The water temperature cannot be adjusted. It is automatically set to approximately 70°C (or 55°C
if eco mode is available and set) and controlled by the heaters control system to prevent bacteria
growth. To avoid scalding, the temperature of the hot water supplied to the taps and showers must
be controlled at the tap or shower. Do not use the water as drinking water.
Any alteration to the appliance, including ue and ue cover, use of non-Whale®spare parts/acces-

5. Whale® Water Heater Operating Instructions
To the User: Read the following instructions carefully.
Observe All Warnings
Never operate the Water Heater without water in it. This appliance must not be connected directly to the
mains water supply without a pressure regulator tted, or any water supply greater than 190 kPa (1.9 bar).
Ensure that the caravan water system, including this Water Heater is full of water and that the vehicle is
level before operating.
When using operating switches provided by the Installer or Vehicle Manufacturer, the Installer or Vehicle
Manufacturer are responsible for providing user instructions and identication of symbols on the Control
Panel.
When using the Water Heater in winter, ensure the ue is not blocked by snow or fallen leaves etc.

Step One: Upon initial operation or to rell after the system has been drained, check that the drain
valve is closed, (see Fig. 1) then ll the system with clean fresh water.
Step Two: To ll, 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 lling. When water
ows smoothly out of the hot tap, the water heater is lled. To allow the remainder of air to
escape from the system, open each hot water tap in turn until water ows smoothly from
each tap.
Protection Against Frost
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). To drain the Water Heater open the drain valve on
the Expanse interface to the open position (see Fig. 2). At the same time the taps must be open in the hot
position to allow air entering the system to aid with the draining process.
Alternatively, if the system is kept active (12V d.c. supply maintained, electrical mains / gas supply availa-
ble) frost protection can be ensured by enabling frost protection on the control panel.
Periods of Disuse
If the Water Heater is not going to be used for more than 3 days, disable the Water Heater on the control
panel, isolate the gas supply by ensuring the gas shut o󰀨 valve to the Water Heater is closed and that the
gas supply is turned o󰀨 (if no other gas appliances require a continued supply).
Please note: Frost damage will not be covered by warranty.

Figure 2. Drain Valve Operation - Open Position
WARNING OPERATING INSTRUCTIONS - DRAIN VALVE
The drain valve is located at the top of the Water Heater, beside the cold and hot water inlet. To operate
the drain valve, turn the yellow lever clockwise 90 degrees to the open position (see Fig. 2). If the plumb-
ing arrangement in the vehicle causes air locking preventing the water heater from draining, consideration
should be given to tting a vacuum relief valve, Whale® Part # AK1228.
Please Note: Water will drip from the discharge pipe of the pressure-relief valve during heating up. The
pressure relief valve must be operated regularly (at least twice a year) by turning the yellow lever from the
closed to open position, to remove lime deposits and to ensure that it is not blocked.
