Observe All Warnings.
Never operate the Water Heater without water in it. This appliance

caravan water system, including this Water Heater is full of water and that the vehicle is level before operating.
If temperatures are likely to fall below zero degree celsius, you
must ensure
that water is drained from the Water
Heater. (Unless Frost Protection is in operation).
Please note:
The Frost Protection setting is only recommended for a period of 3 days or less. The user
must
ensure
that Frost Protection is turned on, activated and remains in operation for the duration for its period of use.

For operation of this Water Heater, a 12V d.c. supply
must be
connected at all times. To operate the Water Heater’s
electric elements, it
must also
be connected to a suitable 230V a.c. supply.
Step One:
Upon initial operation or to refill after the system has been drained, check that the drain valve is
closed, (see Fig. 38A) then fill the system with clean fresh water.
Step Two:
To fill, open one hot tap and switch on the water pump.
Step Three:
Leave the tap open to allow air to escape while the Water Heater is filling. When water flows
smoothly out of the hot tap, the water heater is filled. To allow the remainder of air to escape from the
system, open each hot water tap in turn until water flows smoothly from each tap.
