WATER CONNECTIONS
• When a piping is connected to the unit main body or
removed from it, be sure to use two wrenches to fasten it.
(See the figure 1)
Carefully insulate pipes, valve assemblies and coil con-
nections to avoid condensation forming on the pipes and
dripping on the false ceiling.
• Provide the drain piping as short as possible with down-
ward inclination and no air trap (figure 2 and 3).
• To ensure correct condensate water flow, the drain pipe
should have a gradient of 2% without obstructions.
Furthermore an odour trap of at least 50 mm. depth should
be made to prevent unpleasant odours from reaching the
room.
• Maximum pump head is 500 mm from the bottom edge of
the unit.
The condensate pipe must be insulated.
• If more than one unit is installed in the room, the drain sys-
tem can be made as shown.
External Drain Pan
Procedures:
1. Align the two (2) screw holes in the fixing plate to the two
(2) holes in the external drain pan. (Figure 5)
2. Make sure the drain pan is horizontal.
3. Tighten the two screws and making sure the external
drain pan is installed flush with the fixing plate. (Figure 6)
When the installation is completed, it is necessary to wrap
connecting pipe with thermal insulation to prevent conden-
sation on ceiling tiles.
