Step One: Upon initial operation or to refill after the system has been drained, check that the drain valve is
closed, (see Fig 35A) then fill the system with clean, fresh water.
Step Two: To fill, 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 filling. When 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.
Option 1 Operating with Whale® Water Heater Manual Control Panel
Gas Operation. Operate the switch to the 'on' position. There will be a pre-purge pause of approx. 20
seconds to allow any unburnt 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 The Appliance Off. Operate the switch to the top 'Off' position (O). If the Water Heater is not going to be
used for more than 3 days, isolate the gas supply, by ensuring the gas shut off valve is closed and that the mains
gas supply is turned off. The Water Heater must be fully drained if there is a risk of freezing (unless Frost Protection
is active). Please note: When using the Frost Protection setting, the user must ensure that Frost Protection is
turned on, activated and remains in operation for the duration of its use. This must not exceed 3 days.
Frost damage will not be covered by warranty.
Symbol
Please Note: Water will drip from the discharge pipe of the pressure-relief valve during heat up. The pressure relief
valve must be operated regularly (at least twice a year) by turning the yellow lever in the anti-clockwise direction
(see Fig. 36B), to remove lime deposits and to ensure that it is not blocked. If blocked, please contact Webasto.
General Safety Notes: The operating pressure of the gas supply to the Water Heater must be 28 - 30mbar Butane
or Propane.
Please Note: In cold temperatures, the water in the supply pipe work may freeze and prevent filling.
