9. Verify the shipping anti-freeze solution has been
drained from the VSD, and replaced with the
proper amount of inhibited water coolant that
shipped loose with the chiller. Refer to SEC-
TION 7 - MAINTENANCE in the 201.30-ICOM2
for filling process. ...............................................
10. Verify electrical connections in the VSD are
tight, especially motor leads to terminals. ..........
11. If the VSD provides an optional circuit break-
er at the incoming power connection to
the VSD, make sure the settings are prop-
erly set per the information on the next page.
A. GENERAL:
The following basic checks should be made with the
customer power to the unit switched off.
1. Review the Installation Checklist (Form 201.30-

2. Inspect the unit for installation damage that may
have occurred. If damage is found, take action
and/or repair as appropriate. ...............................
3. Water connection inlet and outlet are at proper
locations, have hangers nearby that would sup-
port their weight and show no visible strain on
chiller nozzles. ...................................................
4. Wiring is complete (power feed terminations in
the VSD), and all sources of electrical supply to
the unit are taken from a single point of isolation
per 201.30-PW2. ................................................
5. Confirm any field control wiring modifications
are in accordance with Form 201.30-PW2 .........
6. Verify the chiller is charged with refrigerant
(pressures match R-134a saturation for ambient
temp). .................................................................
7. Verify that the unit’s protective ground terminal(s)
are properly connected to a suitable grounding
point. Ensure that all unit internal ground con-
nections are tight. ...............................................
8. Verify the following isolation valves are open.
a. Compressor 1 discharge (optional) ...............
b. System 1 condenser subcooler outlet (option-
al) ...................................................................
c. System 1 main oil supply inline ball valve ......
d. System 1 condenser pressure transducer .....
e. System 1 condenser gas to oil eductor .........
