HOW TO USE YOUR MOTORHOME’S EQUIPMENT
Operating Instructions - Drain Valve
The Water Heater must be drained before travelling or if it is not being used for a period of more
than 3 days, or if there is a danger of freezing (unless Frost Protection setting is active). Check
the heater has fully drained if there is a risk of freezing. 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.
If the plumbing system in the vehicle causes air locking preventing the water heater from
draining, consideration should be given to fitting a vacuum relief valve, Whale Part # AK1228.

Winterising
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 off valve to the
Water Heater is closed and that the gas
supply is turned off (if no other gas
appliances require a continued supply). The
Water Heater must be fully drained to avoid
risk of freezing.
General Safety Note: The operating
pressure of the gas supply to the Water
Heater must be either 28-30mBar Butane or
Propane.
Maintenance
To clean and sterilise inside the Water Heater
use diluted sterilising fluid and fully rinse
through with clean water afterwards. The
outside of the appliance should not normally
require cleaning. If it does, isolate the
electrical supplies and wipe down with a soft,
damp cloth only. Do not use abrasive
cleaners. Allow to fully dry before
reconnecting the electrical supplies. If
descaling of this appliance is required, this
can be done using a domestic liquid de-
scaling product and fully rinse through with
clean water afterwards. Cleaning and user
maintenance must not be carried out by
children without supervision.
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 in the anti-
clockwise direction, to remove lime deposits
and to ensure that it is not blocked.
The Whale Heater must be checked
periodically by a Whale Approved Service
Centre/Technician, or a competent person, at
least annually. This must be completed
according to the practice in the country where
it is used and according to the Whale
instructions. Whale recommends annual
testing of gas soundness and combustion by
an accredited LPG engineer. The appliance
contains ESD sensitive components and
therefore must only be opened by a Whale
Approved Service Centre/Technician.
