Supply voltage: Verify that the site voltage supply cor-
responds to the unit requirement and is within the lim-
its given in Section 9.
Switch Settings: Ensure that the unit 'ON/OFF' toggle
switch on the control panel and the microprocessor
board system switches 'S2' and 'S3' are set to 'OFF'.
Set the red emergency stop device on the common in-
put section to '1' (ON). For units fitted with door in-
terlocked isolators the power section doors must be
closed and the devices set to '1' (ON). The customers
disconnection devices can now be set to 'ON'.
The unit is now live!
Compressor heaters: Verify the compressor heaters
are energized.
Chilled Liquid System: Verify that the chilled liquid
system has been installed correctly, and has been com-

missioned with the correct direction of water flow
through the cooler. Purge air from the top of the cooler
using the plugged air vent mounted on the top of the
cooler body.
Cooling Liquid System: Verify that the cooling liq-
uid system has been installed correctly, and has been
commissioned with the correct direction of water flow
through the condenser. Purge air from the top of the
condenser using the plugged air vent mounted at the
top of the condenser water head.
Cooler and Condenser flow rates and
pressure drops must be within the lim-
its given in Section 9. Operation out-
side of these limits is undesirable and
could cause damage.
Flow switch: Verify a chilled liquid flow switch is cor-
rectly fitted in the customer's pipework on the cooler
outlet, and wired into the control panel correctly.
Temperature sensor(s): Ensure the chilled liquid tem-
perature sensors are coated with heat conductive com-
