Entering Chilled Water Piping
• Air vents (to bleed air from system).
• Water pressure gauges with shutoff valves.
• Vibration eliminators.
• Shutoff (isolation) valves.
• Thermometers (if desired).
• Clean-out tees.
• Pipe strainer.
Leaving Chilled Water Piping
• Air vents (to bleed air from system).
• Water pressure gauges with shutoff valves.
• Vibration eliminators.
• Shutoff (isolation) valves.
• Thermometers.
• Clean-out tees.
• Balancing valve.
Drains
A 1/2” drain connection is located under outlet end of
evaporator waterbox for drainage during unit servicing. A
shutoff valve must be installed on drain line.
Pressure Gauges
Install field-supplied pressure components as shown in
figure above. Locate pressure gauges or taps in a straight
run of pipe; avoid placement near elbows, etc. Be sure to
install the gauges at the same elevation on each shell if the
shells have opposite-end water connections.
To read manifolded pressure gauges, open one valve and
close the other (depending upon the reading desired). This
eliminates errors resulting from differently calibrated
gauges installed at unmatched elevations.
Pressure Relief Valves
NOTICE
Evaporator Damage!
Failure to follow instructions below could cause
damage to the evaporator.
To prevent evaporator damage, install pressure relief
valves in the evaporator water system.
Install a water pressure relief valve in the evaporator inlet
piping between the evaporator and the inlet shutoff valve,
as shown in figure above. Water vessels with close-
coupled shutoff valves have a high potential for hydrostatic
pressure buildup on a water temperature increase. Refer to
applicable codes for relief valve installation guidelines.
