Installation of Insulated Water Tank
Note:
The insulated water tank should be installed and keep levelly within 5m and vertically within 3m from the
indoor unit. It can be installed in the room.
Standing water tank must be installed vertically with the bottom on the ground, never suspended. Installation
place must be firm enough and the water tank should be fixed on the wall with bolts to avoid vibration, as
shown in the following figure. Weight capacity of water tank during installation should also be considered.
The minimum clearance from the water tank to
combustible surface must be 500mm.
There should be water pipe, hot water joint and floor drain
near the water tank in favor of water replenishment,
hot water supply and drainage of water tank.
Connection
of inlet/outlet waterway:
Connect the safety check valve attached with the unit
(with the arrow on it pointing at the water tank) with the
water inlet of water tank with PPR pipe according to the
following figure, sealing with unsintered tape. The other
end of the safety check valve should connect with tap
water joint. Connect the hot water pipe and water outlet of
water tank with PPR pipe.

Note :
1. For safe use of water, water outlet/inlet of water tank must
connect with a certain length of PPR pipe ,
L
≥
70×R2(cm, R is inside radius of the pipe). Moreover, heat
preservation should be conducted and metal pipe cannot be
used. For the first use, water tank must be full of water
before the power is on.
2. The water may drip from the discharge pipe of the pressure-
relief device and that this pipe must be left open to the
atmosphere.
3. The pressure-relief device is to be operated regularly to
remove lime deposits and to verify that it is not blocked.
4. The discharge pipe connected to the pressure-relief device is
to be installed in a continuously downward direction and in a
frost-free environment.
5. The appliance is intended to be permanently connected to
the water mains and not connected by a hose- set.
6. The type of the pressure-relief device is A3J, and this device
shall be installed with threaded connection.
7. The replenishing water pressure in water tank shall be
beyond 0.2MPa and below 0.7MPa.
8. The method of water drainage must be operated strictly
abide by the instruction on the label of the water tank.
