SERVICING
To Empty The Water Heater
!
1)
WARNING: THE POTABLE WATER SUPPLY TO THE SYSTEM SHOULD NOT BE SWITCHED OFF
UNTIL THE COLLECTORS ARE SECURELY COVERED BY AN OPAQUE MATERIAL.
For Closed Circuit Series, securely cover the collectors from sunlight with cardboard or other opaque material
BEFORE emptying the water heater.
Turn off the electricity supply.
Flush cold water through the tank to cool both the tank and the closed circuit fluid and turn off water supply.
For Closed Circuit Series, relieve the pressure in the jacket by removing the PR6 or PR200 jacket relief valve.
Extreme care should be taken when removing the valve as the jacket fluid could be at high temperature and under
pressure.
Release the water pressure at the pressure/temperature relief valve by holding the relief arm open.
Disconnect the cold water inlet and allow the water to drain out via a hose fitted to the cold water inlet connection.
Avoid contact with the hot water and ensure that the hose safely discharges hot water away from the roof area.
Hold open the tank relief lever to allow air into the storage tank.
For „L‟ Series only, unscrew and remove the bung plug on the bottom right-hand corner of the right-hand collector.

Anode Replacement
To replace the anode:
1)
Turn off the electricity supply and water supply.
2)
Release the water pressure at the pressure/temperature relief valve by holding the easing gear open.
3)
Drain the cylinder to a level below the anode fitting (see “To Empty the Water Heater” below).
4)
Remove the electrical cover.
5)
Unscrew the anode nut located to the left of the electric element (or burner tube) and withdraw the old anode.
6)
Insert the new anode assembly into the cylinder through the anode socket. Tighten the new anode nut.
7)
Turn on the water supply, dispel air from the tank via a hot water tap or the pressure/temperature relief valve and
then check that the seal on the nut is watertight.
8)
Re-fit the cover and turn on the electricity supply.
