When water is turned o, reverse flow should be prevented using an appropriate non
return valve. This is to prevent the element from operating without water in the tank.
Note: The outlet of the Pressure relief valve should be kept free of obstruction; it should
be installed with the outlet pointing down and plumbed to waste. A tun dish (Kit-C) is
available for this purpose
A 2 Ltr. Expansion vessel (Kit-A) and a Pressure Reducing Valve (Kit-B) are also avail-
able as optional accessories.

ELECTRICAL CONNECTION
All ATC Pacific water heaters come pre-wired with 1.5mm22 core and earth. The heater
should be connected by a suitably qualified electrician in accordance with IEE wiring
regulations.
A suitable termination to the fixed wiring of the premises must be provided adjacent to
the heater using a suitably rated double pole disconnection switch with a minimum of
3mm contact gap and protected by an appropriately rated circuit breaker or RCD.
If this heater is installed in a bathroom it must be supplied from a circuit that is protected
by a high sensitivity RCD with a maximum rating of 30mA.
