Note
Before and during operation, use an appropriate refrigerant leak detector to monitor the operation area and
make sure the technicians can be well aware of any potential or actual leakage of inflammable gas. Make sure the
leak detecting device is applicable to inflammable refrigerant. For example, it should be free of sparks, completely
sealed and safe in nature.
16. Installation of Insulated Water Tank
16.1 Installation measure
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.
