TRUMA ULTRASTORE WATER HEATER
This water heater features a dual source
system of water heating, powered by Liquid
Petroleum Gas or 230V mains electricity. For a
faster heating-up period the appliance can be
simultaneously operated with gas and
electricity. The holding tank has a capacity of 10
ltrs.
WARNING:
Always fit the cowl cap when the water
heater is not being operated. If there is
any risk of frost and preferably each
time you leave the site, the water heater
should be drained leaving all taps open.
Frost damage is not covered by the
warranty.
The system may be fitted to a mains water
supply with special adaptors, which include a
pressure reducer which does not allow
pressure to exceed 2.8 bar.
During the initial operation of a brand new
appliance some fumes are normal. These
should soon disperse if the caravan is well
ventilated.
Filling the Truma Ultrastore
1. Check the safety/drain valve in the cold
water intake is closed. The lever should be
in the horizontal position ((e) see diagram).
2. Set the hot tap in either the washroom or
kitchen in the open position.
3. Switch on the power for the water pump.
4. Leave the tap open to let air escape while
the water heater is filling. The heater is full
when water flows freely from the tap.
5. It may be necessary to adjust the pressure
switch on the water system.
N.B. If only the cold water system is being
used, the heater tank will still be filled with
water and to avoid frost damage it should
always be drained as described below.
Draining the water heater
1. Disconnect the water pump and switch off
power supply where appropriate.
2. Open all hot and cold water taps.
3. Open safety/drain valve and leave in
vertical position (f).
4. The water heater will now drain directly to
the outside. If towing, it is useful to leave
the drain valve open as movement of the
caravan will help to ensure that the system
is completely drained.
5. Ensure that if a water filter is fitted that this
is also drained as well as any water left in
the submersible pump.
WARNING:
Water may be hot enough to scald.
