Connection Of Valves And Pipe Fittings; Water Injection Into Water Tank; How To Drain Water Tank - Haier TP180REL Manual For Installation And Operation

Installation Introduction
Note:
1.The heat transfer fluid is a food grade propylene glycol and is not toxic. However, care must
be taken when handling not to spill or accidentally consume.
2.It is normal that some heat transfer fluid may flow out from the safety valve as the heat
transfer fluid is expanded due to the high solar energy collected.
3.The safety valve should be left open to the atmosphere and its outlet should not be blocked.
The solar storage tank be filled with water before charging the heat transfer fluid with the
closed circuit fluid.
4.The service valve, hose and the funnel are not supplied.

Connection of Valves and Pipe Fittings

Please refer to the
to connect the valves and pipe fittings.
1.Install the temperature and pressure
valve(T/P valve) to the T/P valve joint
of the water tank.
Note：
A T/P valve shall be installed to the tank.
It is normal that some water drops may
flow out from the pressure relief hole as
the water is expanded with heat while
the water temperature in the heater
gets higher.
Continuous leakage of water from the
valve and its drain line may indicate a
problem with the water heater .Failure
to operate the T/P valve easing gear at
least once every six months may
result in the water heater exploding.
The T/P valve should be replaced at
intervals not exceeding 5 years, or
more frequently in areas where there
is a high incidence of water deposits.
2.Install the cold water line, non-return
valve and the stop valve to the cold
water inlet of the tank.

Water Injection into Water Tank

1.Open the cold water inlet valve, and inject water into the water tank through the
outlet.
2.When the air totally exhausts and the water flow is continuous, close the mixing valve and
watch carefully to find out whether the tank is leaking water.
3.Make sure that the cold water inlet is always open while using the water heater.

How to Drain Water Tank

1.Cut off the power and cold water supply.
2.Disconnect the T/P valve, let water flow out until empty.
