North American TwinBed ® II Cycle Control Manifold for Pair of Burners
Installation 8663B
INSTALLATION PROCEDURE
INSTALLATION, OPERATION & MAINTENANCE INSTRUCTIONS
The 8663B Manifold assembly should be mounted and posi- tioned so that it cannot be accidentally operated. Locate the manifold assembly as close to the cycle valves as possible but not where the ambient temperature exceeds 150 F. When piping the compressed air supply to the manifold as- sembly, take care in routing the pipe so that the compressed air temperature dœs not exceed 150 F. Galvanized or pickled pipe is recommended on the compressed air supply to prevent pipe scale from entering the manifold assembly. Instrument quality air is preferred. An 8645A Compressed Air Filter/Separator is recom- mended just upstream of the manifold.
DO NOT attempt to install, operate, or repair these devices with- out proper training in pneumatic systems and devices. Compressed air systems contain high levels of stored energy. DO NOT attempt to connect, disconnect, or repair this product when the system is under pressure. Always exhaust or drain the pressure from a system before performing any service work. Failure to do so can result in serious personal injury. The user must conform to all applicable electrical, mechanical, piping, and other codes in the installation, operation, or repair of these devices. Please contact Fives North American Combustion, Inc. if there are any questions or concerns regarding the safe installation, opera- tion, repair, or maintenance of this equipment.
Stainless steel tubing is recommended for the piping to the indi- vidual components.
NOTE: Before installing the manifold assembly, all air lines in the system should be blown clean to remove any moisture or loose material. Flexible conduit should be piped to the ½ " female connection on each solenoid valve. A lighted indicator is on the solenoids. Disconnect the indicator from the coil and remove the black electrical plug. Using 16 gauge wire, make the proper connec- tions as shown in the wiring diagram. Insert the plug back into the housing and connect it onto the coil.
