Caution
Please take note of the following important points when installing.
• Do not install the unit where leakage of flammable gas may occur.
If gas leaks and accumulates around the unit, it may cause fire ignition.
• Ensure that the drainage piping is connected properly.
If the drainage piping is not connected properly, it may cause water leakage which will dampen the
furniture.
• Do not overcharge the unit.
This unit is factory pre-charged. Overcharge will cause over-current or damage to the compressor.
• Ensure that the units panel is closed after service or installation.
Unsecured panels will cause unit to operate noisily.

Installation Location
• Installation work should be done by the authorized dealer or qualified contractor. Never install the unit
yourself.
• Make sure there is sufficient airflow around the unit.
• Vibration isolator should be provided to reduce the vibration and noise of the unit.
• There should be sufficient space allocated for servicing and maintenance when installing the unit.
Transportation
• The unit should be lifted using a crane. Ensure that the hanger belts
are not touching the coil, top panel and front panel (use protective panel)
as shown in Figure 1.
• The bolt of the base and channel support can be removed after
putting the unit on the fixed location. Figure 1
Water Piping and Fitting
• All water pipe must be insulated to prevent capacity losses and condensation.
• Install a 40-60 mesh strainer to ensure water quality is good.
• Water pipe recommended are black steel pipe and copper pipe.
• During installation, the piping of the unit should be clamp before rotating the installation pipe to reduce the
moment induce on the unit piping.
• Users are recommended to install the pipe and accessories as shown in Figure 2.
• An air vent must be installed at the highest position, while a drainage plug at the lowest position of the
water circuit. Open the air vent to release any air trap in the water circuit.
• Run the clean water through the water inlet and operate the pump to drain out the dirty water. Clean
the strainer after running the pump for 30 minutes.
• Fill up the water circuit after connecting the pipes and equipment. Check water leakage at 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.
