• Refer to the wiring diagram provided on the unit when making electrical wiring.
•
Install an isolator (optional) to prevent electrical shock.
•
Do not ground any electrical equipment to the water piping.
• Operation of the mini chiller without any fan speed controller (Field supply) is limited to an ambient
temperature of
20C. With the fan speed controller (Field supply), the unit is able to operate down
to -5C.
All mini chillers will have a 1/4” access valve provided for along the liquid
line of the refrigerant circuit.This valve is for direct pressure connection
to the fan speed controller. To install the fan speed controller, screw in
the female adaptor to the 1/4” access valve. Use a pair of spanners to
tighten properly(max. torque 15Nm). See Fig. 8. Ensure there is no leakage at
the joint. Wire the fan speed controller to the terminal blocks.
