in place. Starting the unit without all the enclosure panels in place will result in a
high pressure refrigerant fault.
7.
Units with a motor-driven fan may not use duct work unless a booster fan of
equal volume rating has been installed in the duct.
2.3 TO AND FROM PROCESS CONNECTIONS
A.
Use appropriately rated hose or fluid piping to connect the process
piping going to your process to the “to process” connection on the
chiller.
B.
Use appropriately rated hose or fluid piping to connect the process
piping coming back from your process to the “from process”
connection on the chiller.
C.
Install a high volume basket strainer in the From Process line
with isolation valves. A basket strainer or bag filter with a mesh
screen of 20-40 will protect the unit. A “wye” type strainer
is not recommended because it does not have adequate
debris holding capacity.
D.
Process water piping should be designed to avoid excessive
elbows and/or lengths of pipe or hose. If using flexible hose avoid
tight twists or curls and excessive lengths.
E.
Valves and filters may be installed in the process water piping to facilitate service and
maintenance provided that such devices maintain the full inside diameter of the process
connection. If installed, all such devices must be open and clean during unit operation.
F.
It is important to check all external process connections for leaks prior to starting the unit.
It is also important to check external connections for leaks and internal hose clamps and
connections for leaks after servicing the
unit.
2.4 AIR COOLED CONDENSER
A.
Air-cooled condensers require ambient
air temperatures between 60°F and
95°F for efficient operation. Operating
above 95°F may result in elevated
condensing pressures and eventual
shut-down on the high pressure
limit switch. Air temperatures below
60°F may result in over condensing
pressures and cause a low pressure
refrigerant fault. Consult with the
Manufacturer’s service department
for more information on operating with
ambients air temperatures above 95°F
or below 60°F.
