C. Installation instruction
8. When unit operation, put the unit in a well-ventilated place and non-blocking the air vent, so that the
machine can be able to inhale and exhaust enough air, to achieve hot water supply function.
9. There should be with drain around the system unit for drainage. And the surrounding should have
enough space for maintenance. Because the top cover can be opened, at the top side of the unit
should have
≥
800mm space for maintain.
10. Nearby the system unit, there should be reserved a water supply pipe and hot water pipe interface
equipped with valves, the water inlet pipe should be with filter (for cleaning).
11. For waterway connection of this integrated unit, please refer to the following (Fig.4) “Waterway
installation diagram”. On the system unit, there should be installed Three-port valve, Safety valve and
Filter. Connect them to the water inlet and outlet of the unit.
12. If the Heat pump equip with
“Circulation Water Hole”
(optional), It can be connected with SOLAR
WATER HEATER, HEAT RECOVERY SYSTEM and other water heating equipment to heat the water
tank by circulation. Retain original if no need external connection.
13. The working pressure of this water heater tank must
≤
0.7MPa. Water inlet must connect the safety
valve, and its operation pressure is 0.7MPa, Connect another end of the safety valve to water supply
pipe. The safety valve should be connected by a small rubber pipe interlinked with atmosphere; this
pipe must not be blocked, in order to drain the water when the tank’s pressure exceeds 0.7MPa.
14. Water inlet pressure should >0. 1MPa, if the pressure is lower, can connect the pressure pump on
inlet pipe to get the high water flow.
15. Ensure the water tank is full fill with water before turn on the system: First, open the valve on the
water supply inlet, then switch on either valve of the water outlet, and then you can affuse water to the
tank until the water overflow the water outlet valve. After which you can turn off the water outlet valve
and check for leakage. Make sure there is no water leaking.
NOTE: For the first time use, ensure the water tank has been filled with water before turn on the
system.
16. In order to ensure the water tank filled with water, require a certain section of hot water outlet side
should be about 10cm higher than the water heater tank section.
17. The water heater temperature thermal sensor was put and sealed well in a tank by the factory before
launch to market. No need to install it when installation.
18. This water heater unit is filled with refrigerant by the factory, and no need to vacuumize or refill
refrigerant.
19. In the winter cold regions, the water heater unit can not turn off the power, if the system stops running
for a long period in winter, should be drain the tank water to avoid water pipe or tank frost crack.
Meanwhile, we should strengthen or check the external pipe to prevent the pipe frozen.
