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 & 3.
•
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.
