Installation

Supply/Return Pipe Connections to the Loop Pump Kit

(1) Connect the supply and return hos- es to the water-inlet (from supply) and water-outlet (to return) of the unit. The rubber gaskets for the water-in and water-out connections are located in the control box. These gaskets require field installation prior to connecting the water piping to the unit.

(2) Hand tighten the 1" FPT brass swiv- el quick connections to the 1" MPT adapter with P/T ports. Using a wrench, tighten the adapter approxi- mately 1/2 additional turn. Care must be taken to avoid overtightening as to not dislodge the snap ring.

(3)The water lines should be routed not to interfere with access to the unit. The use of a short length of high pres- sure hose with the swivel fitting may simplify the connections and prevent vibration. Pressure/Temperature (P/T) ports are required for troubleshooting the hydronic side of the unit. Extreme care should be taken by the installing contractor to prevent dirt or other for- eign matter from entering the pipes or piping components during construc- tion. Pipes should be capped until they are in place and ready to be connected to the system.

(4)Install the Trane loop pump mod- ule. See installation manual WSHPC- IN-5 or 72-9006-03 for instructions. If the unit does not contain a Trane loop pump module, two ball valves must be installed between the unit and the loop’s water pump to isolate the unit from the system’s water loop during maintenance and emergency situa- tions. See Figure 7.

If the unit s contain a Trane loop pump module, shut-off valves are supplied by the manufacturer within the pump module assembly.

(5)Connect the unit’s water-in and wa- ter-out hose to the loop pump module.

(6)The pumps connect to the load side 230 volt compressor contactor, and re- quire a field installed 6 amp in-line fuse and holder.

(7)Insulate all indoor piping. Equip- ment is designed to operate with fluid temperature of 25ºF to 120ºF
