Filling the Water Heater:
The water heater must be filled with water
before turning on the electrical supply.
1.
Open all hot water taps.
2.
Open the isolating valve at the cold
water inlet slowly and allow the water
heater to fill until water flows through the
system.
3.
Close each hot water tap after the air is
expelled from its line.
4.
Open the Pressure & Temperature Relief
Valve for approximately 10 seconds
by lifting the easing lever on the valve.
Confirm water is relieved to waste
through the relief valve drain pipe.
5.
Lower the lever gently and check it
closes correctly.
Cold Water Connection Diagram:
Note: a combined isolating valve/non-return valve/line strainer may be used.
The expansion control valve is only required where local regulations demand, although it is
recommended in areas where the water saturation index is greater
than 0.40.
