When the pump is running, the icon will turn green and state ‘Pump Running.’

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 ‘Kettle Klear’ or an equivalent
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. Whale recommends annual testing of gas soundness and combustion by an
accredited LPG gas engineer.

The Water Heater is equipped with an electronic diagnostic system which will detect fault conditions ranging from
poor gas or d.c. supply to internal Water Heater malfunctions. In the unlikely event of a failure, the red LED on the
Control Panel will light. To diagnose the problem please refer to the table on page 17.

Option 1 - Whale

®

Water Heater Control Panel

In the unlikely event of a failure, the red LED on the Control Panel will flash a number of times, pause, and repeat
until switched off. Count the number of flashes and refer to the table on page 17.

Gas Lockouts

Gas lockouts must be cleared by moving the gas switch from ‘on’ position to ‘off’ position then back to the ‘on’
position. The complete sequence of switch movements must be completed within 2.5 seconds for a lockout to be
successfully cleared. If there is air in the gas line, e.g. after a gas bottle change, the Water Heater may require
several attempts before it lights.

Other Lockouts

If the lockout is caused when the unit is operated on electric, the lockout can be cleared by moving the electric switch
from ‘on’ position to ‘off’ position then back to the ‘on’ position. The complete sequence of switch movements must

be completed within 2.5 seconds for a lockout to be successfully cleared.

Note: A cycling of the power supply to the unit will not clear a lockout. Some gas lockouts, e.g. Ignition lockout will

still permit use of the appliance in electric only operation.

If the problem persists contact Whale® Support on [phone].

Check gas supply making sure there is gas in the bottle and no
blockage in the gas line. Ensure that Propane is used at
temperatures below +5°C. Clear lockout as described above.

Check that there is water in the appliance. Whale recommends you
wait at least 5 to 10 minutes to allow the Water Heater to cool
before clearing lockout as described above.

Minimum operating voltage is 10V d.c., maximum is 15V d.c., when
measured at the Water Heater. Check battery voltage. If between
10V d.c. and 15V d.c., check connections between Water Heater
and battery. Check alternator or external battery charging. Clear
lockout as described above.

Attempt to clear lockout as shown above. If this fails, contact a
Whale Authorised Service Engineer.

Duo Control Panel

In the unlikely event of a failure, the red ‘ ! ’LED on the Control Panel will light. To identify the lockout press and hold,
both the Water Heater Function Button and ‘ + ’. at the same time. The temperature control bars will light to indicate
the fault code e.g if 1 bar lights, the fault code is 1, if 2 bars lights, the fault code is 2 etc. Press ‘ + ’ to clear the fault
code. Please refer to the table on page 17.

Note: A cycling of the power supply to the unit will not clear a lockout. Some gas lockouts, e.g. ignition lockout and
combustion air faults will still permit use of the appliance in electric only operation.

If the problem persists contact Whale Support on [phone].

Option 3 - Whale iVan® Control Panel

iVan® is equipped with an electronic diagnostic system which will detect fault conditions ranging from poor gas
or d.c. supply to internal heater malfunctions. In the unlikely event of a failure, a pop-up screen will appear with either
a tap icon to indicate there is a problem with the Water Heater, or a van icon to indicate there is a problem with the
Space Heater. Follow the instructions on screen as outlined below:-

Space Heating Fault Screens:

“Check gas supply”

Make sure that there is gas in the bottle and no blockage in the gas line. At temperatures below 5°C use Propane
rather than Butane. Press “Retry” once the checks are complete. If there is a problem with the gas supply (which
cannot be dealt with immediately), select an electric-only heating option instead.

18

“Clear / open vents, retry after 10 minutes”

The Space Heater has overheated due to the vents being either closed or blocked – for example with a cushion or
bag. Remove the blockage and open any closed vents. Leave the heater for 10 minutes to cool down, then try again.

“Check voltage supply”

Ensure that voltage is above 10V d.c. and below 15V d.c. at the Space Heater. This can be done by recharging the
battery.

“Check outside flues for blockages”

The Space Heater is not getting enough air through the flues – check the flue ends and clear any obstructions away
from them.

“Fault on Space Heater”

Contact Whale®Heater Support on [phone] and quote the fault number shown on the screen.

Water Heating Fault Screens:

“Check gas supply”

Make sure that there is gas in the bottle and no blockage in the gas line. At temperatures below 5°C use Propane
rather than Butane. Press “Retry” once the checks are complete. If there is a problem with the gas supply which can
not be dealt with immediately, press “Gas off” and select an electric water heating option instead.

“Check water supply”

The Water Heater isn’t completely full of water. Run the pump with one hot tap open until water flows smoothly out of
the tap. Wait at least 5 to 10 minutes to allow the Water Heater to cool before pressing “Retry”.

“Check voltage supply”

Ensure that voltage is above 10V d.c. and below 15V d.c. at the Water Heater. This can be done by recharging the
battery.

“Fault on Water Heater”

Contact Whale Heater Support on [phone] and quote the fault number shown on the screen.

When using the Water Heater in winter, ensure the flue is not blocked by snow or fallen leaves etc. When not in use,
the Water Heater must be fully drained. This is particularly important during the winter months as a precaution
against freezing. To drain, switch off the water pump at either the pump switch or main switch. Open all the hot water
taps in the vehicle and operate the drain valve fitted in the system. The drain valve must be left in the “open” position
to ensure all the water drains out.
