Maintenance - Whakin WH0822 Guide D'installation Et D'utilisation

When using operating switches provided by the installer or manufacturer, they are responsible for providing user
instructions and identification of symbols on the control panel.
OPERATING INSTRUCTIONS
For operation of the heater, a 12V dc supply must be connected at all times.
Upon initial operation (or to refill after the system has been drained) check the drain valve is closed then fill the
system with clean fresh water. To fill, open one hot tap and switch on the water pump. Leave the tap open to allow air
to escape while the water heater is filling. Once 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.
Please note: In cold temperatures, the water in the supply pipework may freeze, prevent filling and cause damage.
Check that all the gas and/or electricity supplies are turned on.
Gas Operation. Operate the switch to the on (flame) position. There will be a pre-purge pause of approx. 5 seconds
to allow any un-burnt gas to leave the flue. A green LED will light upon successful flame ignition. If there is air in the
gas supply line it may take a few attempts for the gas to ignite. See section 9 for gas lockout re-setting. If the ignition
is not satisfactory, the red LED will flash - refer to the trouble-shooting guide (see Section 9).
Switching Appliance Off. Operate the switch to the top Off position (O). If the heater is not going to be used for
some time, isolate the gas supply and drain water if there is a risk of freezing.
Please Note: The water may drip from the discharge pipe of the pressure-relief valve during heating up. This pipe
must be left open to the atmosphere, must be installed in a continuously downward direction and in a frost-free
environment. The pressure relief valve must be operated regularly (at least twice a year) by turning the yellow lever
in the anti-clock wise direction, to remove lime deposits and to verify that it is not blocked.

MAINTENANCE

To clean and sterilise inside the Water Heater use diluted sterilising fluid and fully rinse through with clean water
afterwards.
Disinfection
• Clean and disinfect the water supply system at least one time per year.
•
In case no water has been taken from the water system for a period of a week or more, drain the
whole water system and rinse it thoroughly before refilling it.
To clean the water system.
1. Drain tank and water system.
2. Make up sterilizing solution as per the manufacturer's recommendations.
3. Fill entire water system with water sterilizing mixture ensuring all air is removed by opening all water
taps in kitchen, bathroom and shower.
4. Close the taps and leave it on for 1-2 hours.
5. Drain the system again.
6. Rinse the system with fresh drinking water.
7. Repeat rinse if necessary.
8. The system can now be used normally.
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. 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.
The Whale ® Water Heater must be checked periodically by a Whale ® authorised service engineer, or 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. We recommend annual testing of gas soundness and combustion by an
accredited LPG gas engineer.
