c) Pipes connection
i) All threaded pipes must be sealed using PTFE tape during connection.
ii) After leak testing of water pipes, all pipes must be insulated to prevent heat lost / heat gain.
iii) All valves on the piping system must be located within the area of the drain pan of the unit. If the site
condition does not permit that, additional insulation or an additional drain pan should be installed to
prevent condensation.
iv) The drain pan is designed to have gradient to ease the flow of condensate water. To facilitate the proper
drainage of condensate water, it is recommended to install the unit at a gradient of 3 ~ 5mm tilting to
the drainage pipe.
v) Condensate water pipe should be insulated to prevent condensation at the outer pipe due to the cool
drainage water. It is recommended that the gradient of the pipe should not be less than 1:75 to facilitate
the flow of drainage water.
Caution : When connecting water pipes, proper sized tools should be used to avoid damage of pipes
or unit.
d) Electrical connection
i) All electrical wiring must be performed by a qualified technician who is certified by the local authorities.
ii) All electrical wires used for wiring must comply to the local codes and regulations.
iii) Fluctuation of electricity should be /-10% of the rated power supply.
iv) During installation, wiring should be connected according to the wiring diagram provided by the
manufacturer and do not wire all of the three speeds of motor together to a single power source.
v) Earth wire is provided and it is being connected to the casing of the motor for protection. The unit should
be properly GROUNDED to avoid incident of electrical shock.
vi) Unit of different model should not share a single 3-speed switch, or the motor will not work properly or
it will be burnt.
