4102/4105 – Water cooled condenser only. Inlet and Outlet chilled or tower water
connections are located at the rear of the 4102/4105, each connection is ¾” MPT
(Male Pipe Tread) (refer to the Chamber Layout drawing at the end of the manual
for connection locations).
a) We recommend the use of industrial ¾” flexible hose grade with a
minimum 8 feet (2.5 meter) in length. The use of flexible hose for the
water inlet and outlet allows easy movement of equipment during
service and troubleshooting.
Hard piping of equipment is not recommended.
We strongly recommend installation of ¾” ball valve at 4102/4105 inlet (chilled or
water tower), along with strainer and pressure gauge for trouble shooting and
equipment testing purpose. The ball valve needs to be accessible during trouble
shooting of equipment and can also be used for testing and servicing equipment.
4102/4105 unit: Apply Teflon tape to 4102/4105 inlet and outlet connection, and
tighten.
b) After each hose connection has been firmly tightened, slowly turn on
water supply to unit and check for leaks at all connections.
c) Verify water pressure is adequate for equipment operation, along with
nominal flow and temperature requirements as follow:
