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 all the pipes and equipment. Check water leakages 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.
Note: For cooling nominal values are based on 12°C / 7°C entering / leaving evaporator water temperature, 35°C air ambient
temperature.
Note: For heating nominal values are based on 40°C / 45°C entering / leaving evaporator water temperature, 7°C DB / 6°C
WB air ambient temperature.
