(3) Cooling in the recirculating air mode
The room air is extracted from the storage room or a wine cellar, subsequently cooled and
dehumidified in the heat pump and finally re-introduced into the room. Recreation rooms,
boiler rooms or utility rooms are ideal installation sites. The air ducts leading through warm
sections must be insulated to prevent the formation of condensation.
(4) variable change over of intake air
A duct system with integrated bypass flaps allows for variable utilization of the heat
contained in the outside air or room air for the production of hot water.
Handle the unit in a proper way
；
Keep the unit in its original package if possible when handling
；
There must be electrical insulation between the unit and location site if the site is with a
metal part, and such electrical insulation must meet the requirements of the relevant electrical
standards.
5. Hydraulic connection
Please notice the points below when connecting the water pipes:
Try best to decrease the resistance in water pipes.
Inner surface of whole pipe system should be clean, no rusty spots and dirts to avoid any
pipe jam. After connecting pipes, please check the leakage status of whole system to
assure there is no leakage firstly and then make the insulation.
Add one-way valve, P&T valve and other safety valve in water way.
The installation of water pipes have to be accordance with the requirements of the local
standard(To avoid too higher water pressure, please install a discharge valve ).
When connecting the water pipes, please prevent any pollution going into pipes.
The male specification of P&T valve is G3/4". After installation, please assure that
drainage pipe is open to the air.
If the discharge outlet of P&T valve is drainage hosepipe, please assure its direction is
down and its outlet is opened to the air. At the same time, the valve should be in a no-
frosting surroundings.
Precautions before installation
Attention

At least pull once half a year the handle of one way valve in order
to remove the sediment of Calcium Carbonate. Please confirm
the device is with no jam. The drainage outlet water temp is high,
please pay attention to it.
Please make good insulation to drainage pipe to prevent pipe
freezing in winter, which may lead to safe accidents.
The discharge mouth water temperature may be higher than e
xpected and please take care to avoid burns.
