Points for Attention during Installation:
1. The unit should be installed horizontally in order to ensure free water drainage and a normal
operation.
2. There should not be any foreign substance piled up in the water drain tray; and all foreign matters
should be removed from the tray. Only if the water drain path is guaranteed to be unobstructed can
the unit be started up.
3. All cooling water pipe valve and cold water pipe of the unit should be supplied with the anti-
condensing water protection. Unless the cooling water pipe valve and cold water pipe are provided
with a heat insulating layer, the extended tray should be installed in the cooling water pipe valve and
the cold water duct when they are installed in the construction field.
4. The connecting length of the air duct should not be greater than that defined by the remained
pressure in the unit. Moreover, the air duct is not allowed to bear any load and should be connected
to the unit.
5. The ceiling suspension unit can only be installed in the place where burning is not to be triggered.
6. The condensed water discharge duct must be installed with an external water seal device.
7. Demand on water quality: the soft water is recommended to be used in order to keep the unit
under a good operating condition.
