Installation
Use the checklist provided below in conjunction with the “General Unit
Requirement Checklist“ to ensure that the unit is properly installed and ready
for operation. Be sure to complete all of the procedures described in this
section before starting the unit for the first time.
[ ] Turn the field supplied disconnect switch, located upstream of the unit, to
the “Off” position.
WARNING
Hazardous Voltage!
Disconnect all electric power, including remote disconnects before
servicing. Follow proper lockout/tagout procedures to ensure the power
can not be inadvertently energized. Failure to disconnect power before
servicing could result in death or serious injury.
[ ] Turn the “System” selection switch (at the Remote Panel) to the “Off”
position and the “Fan” selection switch (if applicable) to the “Auto” or “Off”
position.
[ ] Check all electrical connections for tightness and “point of termination”
accuracy.
[ ] Verify that the condenser airflow will be unobstructed.
[ ] Check the condenser fan blades. Ensure they rotate freely within the fan
orifices and are securely fastened to the fan motor shaft.
[ ] Verify that all compressor service valves, discharge service valves, and
liquid line service valves are back seated on each circuit.
CAUTION
Compressor Damage!
Compressor service valves must be fully opened before start-up
(suction, discharge, liquid line, and oil line). Failure to fully open valves
prior to start-up may cause compressor failure due to lack of refrigerant
and/or oil flow.
[ ] Inspect the interior of the unit for tools and debris.
[ ] Fill the chilled water system.
[ ] Vent the chilled water system at the highest points in the system. Vent the
air out of the chiller barrel by opening the vent, located on the top of the
chiller barrel. Close the vent when the chiller barrel is full of water.
[ ] Once the system has been filled, inspect the entire chilled water piping
system for leaks. Make any necessary repairs before proceeding.
