• All terminals and connection must be tightened.
• Avoid any wires from touching the refrigerant pipe. Apply insulation if necessary.
• Avoid any wires from touching the moving components such as, fan motor, pump & compressor.
Water Piping System Setup
• Fill up the water circuit after connecing all the pipes and equipment. Perform leak checks for all
connections and joints. Do not start the unit when the system is leaking.
• To optimize the capacity of the system, ensure that the system is free of air bubbles.
The air trapped in the system would make the system unbalanced.
Refrigerant Circuit
• All mini chiller units are pre-charged with R410A refrigerant. The only piping that needs to be done is the
water piping from mini chiller (outdoor) to the fan coil unit (indoor).
Safety and Cautions
It is advisable to read through all the safety precautions before installing and commissioning of the unit.
• Contact your dealer for installation, reinstallation or dismantling of unit. Improper handling of unit could
result in leaks, electrical shock or unit malfunction.
• Use the controller handset to switch on/off the unit. Do not plug off the main power supply directly, it would
cause the unit to breakdown.
• Improper connections and fastening could cause electric shock, short circuit and fire.
• Do not introduce foreign objects such as fingers, sticks etc. into the air inlet and outlet.
• Do not spray any chemical agents or flammable agents to the unit. It would cause fire or explosion.
• Do not climb or place objects on top of the mini chiller.
• Do not operate the chiller with wet hands. It would result in electric shock.
• Do not use fuse of different amperage than stated. Using wire, etc. to replace a fuse could cause
equipment damage or fire.
• Provide proper grounding for the mini chiller. Do not connect the ground wire to gas piping, water piping,
lighting rods or telephone ground wire. Improper grounding could cause electrical shock.
• Do not attempt to do any service or maintenance when unit is operating.
• Do not change the settings of the safety devices.
• Do not consume the chilled water in the unit.
• Do not allow water to remain in the water pipes if the unit is not operating for a long period. Water must
be drained out if the unit is not running during winter. Failing to do so would cause the pipe to crack.
• Do not touch the aluminum fin coil. It would damage the coil or cause injury.
Caution
• R410A must be charged as liquid. Usually R410A cylinder is equipped with
a dip-pipe for liquid withdrawal. If there is no dip-pipe, the cylinder should be inverted so as
to withdraw liquid R410A from the valve.
• Do not top-up when servicing leak, as this will reduce the unit performance. Vacuum the unit
thoroughly and then charge the unit with fresh R410A according to the amount recommended in
the specification.
