Figure 3-14 Connecting the Condensate Drain Pipe
If the unit is equipped with a water pump and the user needs to drain from the bottom of the unit. Lead the
drain hose 2 from the drain hole of the water pump (indicated on the baseplate of the cabinet, as shown in
Figure 3-14 ), and connect it to the customer’s condensate drain pipe.
• If the unit is not equipped with condensate drain pump, the condensate drain pan is diversified into two sets
of drain passages to drain the condensate water.
1. During on-site connection, the drain hose 1 and drain hose 3 (reserved length: 2 m, outer diameter:
16 mm) are led from the lower drain holes of the pump and by drain hole of gravity respectively (see
Figure 3-15 ) further connected to the external drain.
2. In order to ensure that the condensate water can be discharged, a separate trap must be provided in the
condensate drain line. The requirements are as follows:
• Use galvanized steel pipe, PVC or flexible polyethylene pipe;
• Allow to slope at 2% in the direction of drainage;
• A Water-trap
1
must be installed at a minimum of 20 cm below the Condensate-drain-pan
2
and the trap must
be installed in the floor under the unit;
• Charge-water
3
in the water trap;
