3. Component Description 3.1 Compliance To Applicable Codes

This spray booth is designed to be in strict accordance with the National Fire Protection Association Standard Number 33, “Spray Application Using Flammable Combustible Materials. The NFPA Standard Safety Code for the Design, Construction and Ventilation of Spray Finishing Operations.” This spray booth meets or exceeds the requirements of the Occupational Safety and Health Administration (OSHA). 3.2 Material Specifications The spray booth panels, filter racks and product doors are constructed of 18-gauge steel, conforming to ASTM A653 “Lock Forming Quality”. All structural steel channel and angle conform to ASTM A36. 3.3 General Description The spray booth consists of four major components: paint area, exhaust fan and chamber, product doors and, in some cases, an air makeup unit. A brief description is provided for these and other related items. 3.3.1 Paint Area The paint area is the actual “booth” part of the spray booth. Parts are placed in this area, through product doors, if so equipped, to be painted. Air flows from the intake filters of the booth to the exhaust filters. The booth is constructed of 18-gauge galvanized sheet metal panels which are bolted together. The booth exhaust is routed through the exhaust plenum at the exit of the booth. The exhaust fan then routes the exhaust out through the exhaust duct and discharges it at a point above the roof height of the building. 3.3.2 Exhaust Fan And Chambers The booth exhaust chamber(s) is/are located as shown in the mechanical drawing package included with this manual. Gases are exhausted through the exhaust duct by an electrically powered fan. The fan is made of spark resistant material and the motor is located out of the air stream. The exhaust chamber(s) operate(s) under a negative pressure to induce the required airflow through the exhaust filters. 3.3.3 Product Doors The product doors can be filtered or solid and may be either overhead doors, bi-fold doors, or tri-fold doors. Some industrial spray booths have an open front in lieu of product doors. Overhead doors are equipped with an intrinsically safe pneumatic safety edge. There are two 3-button controls to operate each door. Doors may also be manually operated. 3.3.4 Door Latch Door latches secure doors in closed position and hold contact against rubber seal. Latches are pressure relief latches that allow doors to open in case of explosion. This feature also allows for ease of booth operator egress from the spray booth by applying moderate pressure to the door from inside the booth.

3.3.5 Door Limit Switch Optional limit switch to indicate when a door is open on the booth. If a door is in the open position, micro switch contact is opened which breaks the circuit for the paint air solenoid. 3.3.6 Air Makeup Unit (Optional) The air makeup unit (AMU) supplies filtered, heated atmospheric air. This unit may be heated by natural gas, LP gas, steam coils or hot water coils. The temperature of the AMU discharge air is controlled by a temperature controller. The airflow capacity of the fan and motor are matched to the airflow capacity of the spray booth exhaust fans. Some air makeup units also have the capability to provide a paint cure cycle. This cycle, employed after the paint spraying operations are complete, typically involves supplying air that is heated to the paint area of the booth to decrease paint cure times. 3.4 Exhaust Filter Manometer Manometer is used to measure pressure drop across exhaust filters to indicate the condition of the filters. 3.5 Air Solenoid Valve The function of this valve is to interrupt supply of compressed air to painting equipment under certain conditions. This is done to prevent painting from occurring when the booth is not operating as designed or if any booth doors are open. The air solenoid valve is electrically interlocked with booth intake and exhaust fans. If optional switches are purchased, it is also interlocked with product doors and personnel doors. lf a fan is not operating properly, or if a door is open, the air solenoid valve will shut off flow of pressurized air to spray gun. Unit should be installed downstream of any regulators and filters and upstream of painting equipment. It should be located near fitting to which painting equipment connects in order to ensure rapid loss of supply pressure. 3.6 Control Panel The spray booth may be equipped with an optional electrical control panel. Electrical schematics are located inside the control panel. Also shown on this drawing is the wiring required for installation. No spare parts are provided with control panel. Panel and its associated wiring must be installed by a licensed electrician. The cabinet that houses controls is either NEMA 1 or NEMA 12 rated. It is not suitable for installation in a Class I, Division II area. Refer to Chapter 6 in the NFPA 33 Standard and consult with the local authority having jurisdiction for definition of this area for paint spray booth.

4. Installation 4.1 General

This manual is a guide for installing a variety of spray booths. The assembly drawings enclosed are specific for the booth you have purchased. This drawing is an exploded isometric drawing showing the relationship of each panel or part to the next one. A packing list of all components is provided and must be used in addition to the drawing to identify all components. All DAMAGES MUST be reported within 24 hours of receipt and a freight claim filed with the carrier. 4.2 Preliminary RTT booths are manufactured in accordance with NFPA 33 standard for spray application using flammable or combustable materials. However, local codes and regulations may apply to the installation and use of this product. All permits and approvals should be obtained prior to installation and use of the spray booth. 1. Uncrate and inventory all spray booth components to ensure all of the parts are accounted for. Each component is numbered on the exploded view. 2. The floor surface of the booth must be non-combustible material of such character as to facilitate the safe cleaning and removal of residues. The floor surface must be flat and level.

3. Mark the dimensional outline of booth on floor. 4. Follow the step-by-step instructions provided. 4.2.1 Recommended Booth Layout Tools >> Chalk line or self-leveling 5-way laser >> Tape measure >> Marker >> Framing square

Use the 3-4-5 method (Pythagorean Theorem) A² + B² = C² for a right triangle to layout and square the booth. C is the longest side (hypotenuse) and A and B are the two shorter legs. If a triangle has sides measuring 3, 4 and 5 feet (or any other unit), it must be a right triangle with a 90° angle between the short sides. You can multiply each number by the same amount and still use this method. For example let’s say that the booth width being installed is 9' I.D., use a multiplier of 3 to achieve the 9' I.D. working width of the booth for your first line (A²) and the right triangle will consist of the following dimensions: >> 3 x 3 = 9 (first line A²) >> 4 x 3 = 12 (second line B²) >> 5 x 3 = 15 (third line C²) Step one: Locate a building drawing showing the booth in the building. a b c a 2 +b 2 =c 2

4.2.2 Booth Layout Steps Step 1: Locate a building drawing showing the booth in the building. Step 2: Locate a dimension shown from a reference point such as outside wall, pit, conveyor, building structure, other equipment, etc. to the inside dimension of spray booth. Step 3: Using a chalk line, mark that dimension at two points along a wall (reference point example) and snap a line on the floor. Step 4: Locate the back of the booth and make a mark on the first line that was snapped for the first corner of the booth (I.D.), using 9’ as the first line dimension (A² example) make another mark at 9′ for the back wall of the booth Step 5: Using 12′ as our second line dimension (B² example) make another mark at 12′ from one of the corner markings of the back wall off of the first line snapped. When doing so, be sure to stay as square as possible. This is when a framing square comes in handy. Once marked, snap the second line. Step 6: Using 15′ as our third line dimension (C² example) mark and scribe an arc crossing the end of the second line snapped from the opposing corner marking of the back wall off of the first line snapped. This mark is now perfectly square to the back wall of the booth. Snap the third line between these two marks. Step 7: Pull two points off of the third line and snap a fourth line marking the interior work area of the booth. Now that the square interior of the booth is complete, proceed with the rest of the booth (exhaust chambers, fans, air make-up unit etc.) to verify that all components are placed as planned without obstruction. Step 8: Using a laser, verify building clearance, fan ductwork and air makeup unit (if applicable) orientation. Step 9: Using a laser, verify that the floor is level. Any area that will have more than a ¼″ gap will need to be shimmed. Step 10: Double check the entire layout for accuracy and to prevent losing your layout, spray clear coat over it before beginning the booth installation.

4.2.3 Recommended Booth Installation Tools >> Step ladders (4′, 6′ and 8′) and multi-use ladder >> Wrench and socket sets (1/2″, 9/16″ and 3/4″ most common)

>> Screw driver set >> Allen wrenches

>> Hammer and dead blow >> Alignment pins and pry bar >> Level (magnetic) >> Caulk gun and utility knife >> 1/4″ and 3/8″ drive cordless impacts >> 1/2″ drive drill >> Drill bits and uni-bit/ step-bit >> Hammer drill (SDS) >> Metal nibblers/ cutters >> Cut-off saw >> Welding and plasma machines

4.3 Planning Ahead 1. Clearances between other work areas and combustible storage areas must be held as follows: >> 3 ft. minimum clearance at all sides and sealed entry ways (i.e., door ways). >> 3 ft. minimum clearance at all non-sealed entry ways (i.e., the open face of spray booth or a silhouette openings). >> 10 ft. minimum clearance must be held between the exhaust stack of the booth and the intake of another apparatus. NFPA 33 dictates a minimum discharge clearance of 3 ft. from the nearest combustible material; however, stack height requirements vary with individual states and can be up to 1½ times the building’s roof height from grade. 2. Permits are not included. It is the responsibility of the end user to acquire all permits to install a booth. 3. A FIRE SUPRESSION SYSTEM IS NOT INCLUDED WITH THE BOOTH BUT IT IS REQUIRED. Generally this is supplied and installed by a licensed local installer. 4. Electrical installation must be performed by a licensed electrician familiar with national, local electrical codes and regulations in your location.

4.4 Booth Assembly When assembling the booth, leave bolts finger tight until the entire booth is assembled. All flanges should face outward. Install bolts from inside so nut is outside of the booth. Use a drift pin to align panel holes when two or more panels are difficult to align by hand. Lay out all floor channel for exhaust chamber and walls. As you attach wall panels together, they will also bolt to the floor channel.

Prevent serious injury or death. Most booth components weigh 50-500 lbs. Use adequate lifting devices to raise, move and install booth components. WARNING Prevent equipment damage. Spray booth roof will not support a person. Do not attempt to stand or walk on spray booth roof. NOTICE

Refer to exploded view drawings included with your spray booth. 1. Starting with exhaust chamber at either rear corner, bolt one corner panel and one rear wall corner panel together (use tie channel where applicable). 2. Bolt opposite rear sidewall panel to rear wall panel. 3. Bolt all rear wall panels in place.

CHAMBER SIDE PANEL

4. Bolt tie channel along top edge of rear wall panels. 5. Place exhaust fan panel above side and rear wall panels and bolt in place. 6. Insert filter filler panels between sidewall, roof panels and exhaust chamber. Bolt in place. 7. Following exploded view drawings, continue alternately assembling wall panels and roof panels to each other until you reach front end of booth. Finish off roof section by attaching fire curtain if needed. If booth has front doors, no fire curtain is needed.

FILTER FILLER PANEL

BOOTH SIDE PANEL

8. Verify walls are plumb and booth is square and on floor layout marks. Tighten all mounting hardware. 9. Anchor floor channel to floor at a minimum of every 12 inches. 10. Caulk all panel joints inside the booth with the caulk provided. Do not use a silicone caulk. 11. If booth is supplied with a personnel door or product doors, apply gasket to perimeter of all door openings. Attach door hardware and adjust latches. Level door with doors off, then attach doors to hinges.

4.6 Manometer Locate manometer on the exhaust chamber so that hardware is not visible inside the booth and can easily be viewed daily. Install close to exhaust filter wall to keep tubing length to a minimum. Excess tubing length will reduce accuracy of the manometer. The high port will connect to work chamber, and the low port will connect to chamber on the suction side of the filter grid.

1. Drill a hole in booth wall just large enough for the plastic hose barb to fit through (approx. 13/32). Install washer and nut on back side. Do not over tighten.

2. Mount manometer on booth wall and ensure it is level using bubble level on manometer. Manometer must be level or it will not be accurate.

3. Turn “Zero Set” knob counter clockwise until it stops, then turn knob counter clockwise three full turns. This will place the adjustment knob in the middle of its travel range. Remove fill plug at top of manometer and slowly fill with red fluid. You will not need the entire bottle. Stop filling as soon as you can see the red fluid enter clear tube at bottom of the manometer. Turn “Zero Set” adjustment knob to set red fluid on 0 mark. If you overfill gauge, remove excess fluid by inserting a pipe cleaner through fill port to blot up excess oil. Once the red fluid is set on zero, replace the fill cap.

Complete booth assembly and then perform steps 4-6 to set manometer. IMPORTANT: All filters in the booth must be installed and new in order to get an accurate baseline.

4. Turn on exhaust fan. If exhaust fan is connected to a VFD to control the speed of the fan, make sure it is set to run at full speed. You will notice the red fluid should move up the scale and then settle at a number. The number will be different from booth to booth, but that does not matter, this is just a baseline setting.

5. Wherever the red fluid stops is where you will place the green arrow. In this example, the red fluid stopped at .25 inches of water column. So because we know our filters are rated for .5 inches of water column, and we know that with clean filters the fan is drawing .25 inches of water column, we simply add the two numbers together to tell us where the filters will pack out. .25 inches of water + .5 inches of water = .75 inches of water total

6. Now that baseline is set, measure up the scale .5 inches of water. That is where you will place the red arrow.

At this point, your manometer is set up and ready to use. You should never need to move the arrows once they are placed. Always check the manometer before turning the fan on to ensure the red fluid is sitting on the 0 mark. If the fluid is not on 0, turn “Zero Set” knob to adjust fluid to zero before starting fan.

4.7 Exhaust Filter Installation Install one wire grid in each filter cell with prongs facing into booth. Exhaust filters will be attached to prongs.

4.8 Intake Filter Installation If booth has an intake plenum, insert intake filter into filter grid. The side marked “Air Leaving Side” on filter goes toward inside of booth.

4.9 Motor Installation Couplings, drive belts, chains or other mounted devices must be in proper alignment, balanced and secure for safe motor operation. 4.9.1 Mounting This motor must be securely mounted. Sufficient ventilation must be provided to insure proper operation. 4.9.2 Install Sheaves And Fan Belts 1. The fan sheave (A) and motor sheave (B) must be in axial alignment. Shafts must be parallel in both vertical and horizontal planes. 2. The sheaves must be in radial alignment. When sheaves are of equal width, align with a straightedge (C). When sheaves are of unequal width, align center of sheaves. 3. Check fan belts for proper tension and for signs of wear. Belt A B C

should have a slight sag at bottom of sheaves. Belt (D) is properly adjusted. Belt (E) is too loose. Belt (F) is too tight.

4.9.3 Electrical

Prevent serious injury or death. Electrical installations must be performed by qualified electricians. Installation must conform to all national, local, and provincial codes and standards. WARNING

Complete booth assembly and then perform steps 1-5 below to connect electrical service to motor. 1. Determine voltage at your facility. RTT does not recommend using 120V single phase on motors above 1HP. 2. If a control panel or motor starter was ordered with this booth, confirm that the voltage and phase on the control panel matches the voltage and phase you intend to use. 3. Locate the wiring diagram inside the control panel that matches your voltage, phase, and HP. 4. Some motors may have 2 additional red wires. These wires are for an internal thermal overload. We do not use these wires and they should be capped off with wire nuts or electrical tape. 5. Locate the rotation arrow on the fan and verify belts are rotating in the direction of the arrow. If the belts are not rotating in the direction of the arrow, reverse the motor. 6. To insure proper wiring refer to motor nameplate for wiring diagram.

4.10 Tubeaxial Fan

WARNING

Fan assembly is heavy. Fan assembly weight is approximately 50 - 200 lbs., depending on model. Use an adequate lifting device to install fan assembly.

WARNING

Prevent serious injury or death. Electrical installations must be performed by qualified electricians. Installation must conform to all national, local, and provincial codes and standards.

The fan and motor assembly will bolt to fan panel. 4.11 Exhaust Duct Installation If equipped with optional exhaust ductwork, it is recommended to have this professionally installed. To assemble ductwork: 1. Bolt pipe with connecting ring to the exhaust fan. 2. Remaining ductwork is crimped on one end to interlock

with the next section. Crimped ends of duct shall be installed with the crimped edge pointed inward in the direction of airflow. 3. Your ARV (automatic roof ventilator) will be mounted on top. 4. Storm collar will attach to duct above flashing to make it weather proof. Where more than 25 ft. of piping is required, static pressure (resistance) is increased and the airflow may be hindered when using the standard exhaust unit recommended for use with the booth. Where a piping arrangement of an unusual nature is necessary or where two or more elbows are used, a similar condition may exist. Therefore, if either of these situations arises, contact RTT for recommendations.

Exhaust piping, including the ARV (if used), should extend a minimum of 6 ft. above the highest point of building. There should be an access door just above exhaust unit.
