To Empty the Water Heater
Warning: The water supply to the system should not be switched off until the collectors are securely covered by an
opaque material.
1)
Turn off the electricity supply.
2)
Flush cold water through the tank to cool the tank and turn off water supply.
3)
Release the water pressure at the temperature pressure relief valve by holding the lever open.
4)
Disconnect the cold water inlet and allow the water to drain out via a hose fitted to the cold water inlet
connection.
5)
Avoid contact with the hot water and ensure that the hose safely discharges hot water away from the roof
area.
6)
Hold open the TPR valve lever to allow air into the storage tank.
Anode Replacement
To replace the anode:
1)
Turn off the electricity supply and water supply.
2)
Release the water pressure at the temperature pressure relief valve by holding the lever open.
3)
Drain the cylinder to a level below the anode fitting (see
“To Empty the Water Heater”
above).
4)
Remove the center cap on the side of the tank where the Hot Water outlet is located to uncover the anode nut. Unscrew
the anode nut and withdraw the old anode.
5)
Insert the new anode assembly into the cylinder through the anode socket. Tighten the new anode nut. Plug back the
center cap
6)
Turn on the water supply, dispel air from the tank via a hot water tap or the temperature pressure relief valve and then
check that the seal on the nut is watertight.
7)
Re-fit the cover and turn on the electricity supply.
Warning
: Do not turn power on until the water heater is filled with water or damage to the heating element will result.
Troubleshooting – Save A Service Call
Should your Solahart not provide hot water please check the following before requesting a service call:
1)
Shading from trees is not excessive and is not covering the collectors for all or part of the day.
2)
Hot water usage is not excessive.
3)
Hot water is not leaking from within the plumbing system.
4)
Electrical heating unit switch and/or time switch is turned ON.
5)
