The settings for the circuit breaker should
not be changed from the settings. The war-
ranty will be voided if the breaker settings
are changed.
13. Check the chiller for refrigerant leaks at joints or
water piping leaks. .............................................
14. Make sure 9 liters (2.38 gallons) of compressor
oil were added to both circuits. ..........................
15. Make sure the control panel is free of foreign
material (wires, metal chips, tools, documents,
etc.). Check for signs of water or moisture. .......
16. Make sure the leaving liquid temperature sensor
is coated with the heat conductive compound
(P/N 013-00890-000), and is inserted to the bot-
tom of the water outlet sensor well in the cooler.
This sensor must always be fully inserted in the
water outlet sensor well. ....................................
17. Make sure the flow switches are connected be-
tween Terminals 2 and 12 and 2 and 13 on Ter-
minal Block 1TB in the control panel. .................
18. Check whenever the pump contacts are used,
the coil of the pump starter should be suppressed
with an RC suppressor (P/N 031-00808-000). ...
B. START-UP
Panel Check
Only qualied individuals are permit-
ted to service this product, and are to
be knowledgeable of, and adhere to, all
safe work practices as required by local
codes. Use proper personal protection
where and when required.
1. Verify that the voltage supply corresponds to
the unit requirement, and is within the limits as
specified in SECTION 4 - TECHNICAL DATA in
Form 201.30-ICOM2..........................................
2. Make sure the unit switch at the bottom of the
keypad is in the OFF (O) position. .....................
3. Apply 3-phase power to the chiller. Turn on the
optional panel circuit breaker, if supplied. ..........
4. Verify the control panel display is illuminated.
To prevent the compressors from starting, make
sure that the SYSTEM SWITCHES key is off for
both systems. .....................................................
5. Use a clamp-on ammeter to make sure the both
compressor heaters are turned on. Heater cur-
rent draw is approximately 3A. ...........................
6. Confirm that the compressor overload current
settings have been correctly adjusted by the fac-
tory. These are not normally required to be re-
set. Use the VSD DATA key on the control panel,
navigate to the COMP1 MOTOR OVERLOAD =
### AMPS and COMP2 MOTOR OVERLOAD
= ### AMPS screens. The values should match
the values on the overload setting label, which is
located inside of the VSD cabinet. If the values
do not match, an adjustment is required inside
the VSD cabinet by qualified service personnel..

Liquid Control Setpoint
Program the chilled and condenser liquid (optional heat
pump) setpoints and ranges, then record them below:
1. Leaving Chilled Liquid
Temp Setpoint = ______________________°F (°C)
2. Leaving Chilled Liquid
Temp Control Range = _________________°F (°C)
3. Maximum Leaving Chilled Liquid
Remote Temp Reset = _________________°F (°C)
4. Leaving Condenser Liquid

Date/Time and Daily Schedule
1. Program the date and time by making sure that
the CLK Jumper JP2 on the control board is in
the ON position. Press the DATE/TIME key to
set the date and time. ........................................
2. Program the daily and holiday start/stop by
pressing the SCHEDULE key. ............................
C. CHILLER SYSTEM
After completion of the following
checks for System 1, switch off the Sys-
tem 1 switch on the keypad and repeat
the process for System 2. When both
systems are running correctly, stop the
unit, switch all applicable switches ON,
and restart the unit.
1. Ensure power is on the chiller to energize the
compressor heaters 24 hours prior to start-up. ..
2. Ensure the SYSTEM SWITCHES key is OFF for
both systems. .....................................................
3. Turn the unit switch to the ON position. .............
4. If the chilled and condenser liquid pumps are
manually operated, start the pumps. The con-
trol center will not allow the chiller to start un-
less flow is established through the unit. If the
pumps are wired to the control center, over-
ride the contact to start the pumps to verify the
flow. ....................................................................
5. Throttle back flow to make sure the flow switch
opens with a loss of flow. If the pump is turned
off during chiller operation, it is recommended
that auxiliary pump contacts be placed in series
with the flow switch for additional protection.......

6. Evaluate cooler and condenser water flow indica-
tion compared to design information found on the
sales order. If shell pressure drop is used, it should
be within +/- 15% of the rating information. ........
7. If the chilled water and condenser pump run
contacts on the chiller were overridden to check
flow, remove overrides. Pumps will get start
command when chiller initiates run. ...................
8. Press the SYSTEM SWITCHES key, and turn
on System 1 or 2 SWITCH. There may be a few
seconds delay before the compressor starts be-
cause of the anti-recycle timer. Be ready, when
each compressor starts, to switch the UNIT switch
to the OFF position immediately, if any unusual
noises or other adverse conditions develop. ......
9. When the compressor starts, press the relevant
System Pressures key to verify that oil differen-
tial pressure develops immediately. If oil pres-
sure does not develop, the automatic controls
will shut down the compressor. Under no cir-
cumstances should a restart attempt be made
on a compressor, which does not develop oil
pressure immediately. Switch the UNIT switch
to the OFF position. . ..........................................
10. As the chiller is started, verify the refrigerant lev-
el sensor tracks level from empty condenser to
fully flooded level sensor probe over the range
of less than 10% to almost 100%. ......................
11. Adjust condenser refrigerant liquid level setpoint
to a value that covers the subcooler top and pro-
vides proper evaporator performance with the
chiller running steady. ........................................
12. After the chiller is at full load at Design Leaving
Chilled Liquid Temperature, capture the operat-
ing data to print or save to text file. ....................
