b) We strongly recommend installation of ½” 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.
c) Connections to unit: Apply Teflon tape to inlet and outlet connection, and tighten each
connection accordingly.
d) After each hose connections have been firmly tightened, slowly turn on water supply to unit
and check for leaks at all connections.
e) Verify water pressure is adequate for equipment operation, along with nominal flow and
temperature requirements as follow:
Tower water: ≤ 85°F (29.5°C). ≥ 20 PSI differential (1.4 bar)
Water flow rate at maximum load = 7 gpm (26.5 L/min)
Water flow rate at average load = 4.5 gpm (17 L/min)
Chilled water: ≤ 45°F (7.5°C). ≥ 20 PSI (1.4 bar)
Water flow rate at maximum load = 3.5 gpm (13.2 L/min)
Water flow rate at average load = 2.0 gpm (7.6 L/min)
