2. System Installation a. Installing Module

Loosen the connections holding the curved cover in place. Lift off the curved cover being careful of protruding parts (e.g. air filter)

Remove orange stoppers from module and manifold. Add manifold to center of module using stem adapter. Rotate the module so the red terminal is on the left and the black terminal is on the right. Push the module on the frame up against the stoppers. If done correctly, the module inlet (the connection that is NOT in the middle of the module top) will be facing outwards from the system, and the edge of the module will be in line with the edge of the frame. The vertical tube that is attached to a T-junction should be pushed into the module inlet. If placed correctly, pulling on the tube firmly should not disconnect it from the module. The tubing that comes from the pump should be pushed into the horizontal connection coming from the center of the module. The tubing that comes from the waste line (above the center of the module) should be pushed into the vertical connection coming from this point. Each module has one red and one black electrical terminal, with each terminal having two M8 nuts. Unscrew one of the nuts from the red terminal. Place the red cable from the system on the red electrical terminal, then screw the nut back on. Tighten using two size 13 wrenches, one on the top nut and one on the bottom nut. Repeat the process with the black terminal and black cable.

b. Placing Leak Sensor Wires

Take the two wires and place them on either side of the single module connection.

c. Water Connections

Size 3/8” tubing should be used to connect the inlet to the middle connection on the side of the unit. The purified (Out) water is discharged through the top connection. Concentrate (Waste) is discharged through the bottom connection.

d. Powering System Up/Down

A power cable is provided with the system. Connect the cable to the power connection on side of unit. Turn the switch on to power the system.

e. Replacement of CIP Solution

Loosen the white tube gland by rotating the gland nut (topmost piece, circled in red here) whilst holding the bottle steady. After the gland nut is loose, unscrew the lid of the CIP container, being careful of any tension seen in the white tube that could cause splashed of the cleaning solution. Fill container with new solution. Screw the lid of the CIP container back on and tighten the gland nut until tube is held. Avoid over tightening.


2. System Installation (Cont') e. Replacement of CIP Solution (Cont')

On the LCD, navigate to Voltea DiUse/Start Process/Alarms/Clear Alarms, and press Enter to clear the Low CIP Level alarm.

f. Starting System - Operation With Pressurized Tank

Once the pressure on the Out line after the system drops below 3.5 bar (51 PSI), the system will automatically start producing water. When the pressure increases above 3.5 bar (51 PSI), the system will stop producing water (once its operational cycle is finished) and enter standby mode. A second pressure switch is present, which will trigger an alarm if the outlet pressure reduces below 1.5 bar (21 PSI). Using the LCD, press Enter to go from Voltea DiUse to IDLE-START. Press Enter again to put the system in operation mode.


3. Basic System Functions

a. Alarms

The alarms can be viewed on the LCD at Voltea DiUse/Idle, then pressing the down arrow to reach Alarms. Alarms will show you a binary representation of which alarms are active. Pressing Enter will take you to the Alarms List, if there are any active. In the alarms list, it is possible to scroll through alarms and see the date and time at which they last occurred, with any active alarms indicated by a "yes". Any alarm that is no longer active can be reset by pressing enter when viewed. The full alarm list is shown on the next page.

General Description

Low Purify

Flow Low Purify

Low flow during the Purify phase. Set in the Set Points screen. Only triggered during the Purify phase. Low flow during the Waste phase. Set in the Set Points screen. Only triggered during the Waste phase. Emergency shutoff of DiUse System due to high internal temperature within the electrical cabinet. Set in Set Points. Pure line pressure has dropped below the set point of the bypass pressure switch (standard is 1.5 bar (21 PSI). Voltea recommends opening a bypass, or reviewing operational parameters with Voltea staff. If the two leakage sensors come into contact with water, this alarm will be triggered and the system will go into idle until ENTER is pressed.

4. Advanced System Functions a. Changing Output Conductivity

Output conductivity can be adjusted as follows:

Start at Voltea DiUse page, press ENTER to go to IDLE page. Once in IDLE, press DOWN 6 times (this will take you through several screens). You will arrive at Target Conductivity page. Press ENTER to begin editing the target EC. Use UP and DOWN to increase or decrease the highlighted digit. Press enter to confirm each digit. When ENTER is pressed at the final digit, the screen will flash with the word SAVED, indicating that the system has accepted the new target EC value. To return to the IDLE page, press ESC 2 times. To return to Voltea DiUse page after reaching IDLE page, press ESC, then press ENTER to confirm exit from the process.

b. How To Change Flow Restrictors

Locate the High and Low flow restrictor positions, which are inside the "High Flow Valve", circled in red here. Remove the inlet assembly from its supports by carefully pulling on the two black valve bodies.


4. Advanced System Functions (Cont')

b. How To Change Flow Restrictors

To remove the connections holding the flow restrictors in place, use a flathead screwdriver to hold the latching mechanism in place, whilst rotating the black fitting counter-clockwise by 90 degrees . This will unlock the fitting, which can then be removed by pulling away from the assembly.

Once the fittings are removed, use a small flathead screwdriver to lever out the flow restrictors, being careful not to damage the central mechanism. Replace these flow restrictors with the desired ones, making sure that the "High Flow" restrictor is facing towards the module inlet, and the "Low Flow" restrictor is facing the pump. Push the black fittings back onto the valve assembly, rotating them 90 degrees clockwise to lock in position.

On the LCD, update the Pure Flow Target set point in Systems/Set Points. This value is only in Liters per minute (L/min). If adding an X flow restrictor in the pure valve, set the pump to X - 0.2.; i.e., if you add a 2 flow restrictor, set the pump to 1.8 L/min.


4. Advanced System Functions (Cont') c. How To Receive Data and Alarms Remotely

The system comes with a GSM communication antennae. In order to utilize this feature, insert a data-ready, unlocked SIM card into the SIM slot. Once the SIM is placed, use the Laptop functions detailed below in the section "Adding Email and Telephone Users", to put in the email address and phone number of the data/alarm recipient to receive information. Nano or micro SIM's are not compatible with the card holder.

d. Connecting to Laptop

Ensure no power is applied. These functions are generally not needed for the setup, but are required for adding email and telephone functionality. To do this, connect the laptop to the system using a USB 2.0 cable placed directly into the USB port of the PCB. Power up the system after connection. Open the "Voltea Command" program to access the low- level functions of the system. Double click on the "COM3" field. In the dialogue box, edit the "Send/Receive on Comm." field to reflect the virtual port that the USB is connected to. This can be found under "Ports" in the device manager. Press OK.

Press the Start button to begin communication. If errors occur after multiple attempts, unplug the USB from the laptop and plug it in again.

e. Adding Email and Telephone Users

It is possible to input email addresses and phone numbers into a list that can be used to receive data and alarms from the system. This list can hold up to ten addresses. Using the "Voltea Command" program, double click on the text "Set User Email ID". In the dialog box that appears, edit the default address. Press OK. To save the email address, press the arrow on the left of the text. Repeat the process with "Set User Mobile No." to enter the mobile phone number associated with the email address. This number will receive SMS messages with information on the system. To confirm that the address was entered correctly, press the arrow on the left of the "Get User Mobile No & Email ID". The number and email ID will be displayed on the Communication panel to the right. When advised by Voltea, settings can be adjusted via the LCD. Navigate to System, press ENTER and then Down to Set points. A PIN will be required. A cursor can be seen that shows which digit is being edited. UP increases the value, and DOWN decreases it. Press ENTER to move onto the next digit. The edit will only be saved when ENTER is pressed on the final digit. Use the Up/Down arrows to navigate to the set point. Press ENTER to edit the set point. The valves can be changed as described above. A full list of variables is shown below. Please note that timings cannot be input when they are lower than the value on the left, or higher than the value on the right.
