IMPORTANT: Do not under any circumstances switch on the immersion heater before the
primary tank is filled.
Serious damage may result to the heater in addition to danger of personal injury and damage
to property if the heater is switched on when dry.
IMPORTANT: Always isolate electrical supplies and if necessary the water supply before
working on the unit.
IMPORTANT: Always fill and pressurise the secondary (domestic) tank first, filling and
pressurising the primary (heating) tank may result in crushing damage to the domestic tank.
IMPORTANT: ACV recommends the use of a corrosion inhibitor in the primary (heating)
system. The warranty will be invalidated if upon inspection it is found that a tank has failed
due to corrosion caused by the lack of an inhibitor.
IMPORTANT: Ensure that the air is purged from the primary jacket using the air vent on the top
centre of the cylinder.
