Safety
This chapter provides an overview of all important actions required
for a safe and trouble-free operation.
3.1 General safety instructions
Operate the water heater only when fully installed and with all
safety equipment in place.
Unsuitable tools or incorrect handling can result in damage to
the water heater.
DANGER Scalding
The water is heated inside the water tank to 60 °C
(140 °F). There is a risk of scalding at outlet
temperatures above 43 °C (109 °F).
» Ensure that outflowing water does not directly
contact your body.
CAUTION Injury
Where children or persons with limited physical,
sensory or mental capabilities are allowed to control
this water heater, ensure that this will only happen
under supervision or after appropriate instruction by
a person responsible for their safety.
» Children should be supervised to ensure that they
never play with the water heater.
Never place any objects on top of the water heater.
Objects placed on top of the water heater can increase
the noise level developed by the water heater through
vibrations.
Never cover the water heater.
The water heater draws in air. Covering the inlet slots
reduces the air intake. This reduces the efficiency of
the water heater and can even lead to one of the safety
devices interrupting the water heater operation.
3.2 Intended use
This water heater produces hot water automatically.
The water heater can be installed and operated in the open as well
as in enclosed spaces. The temperature of the air that is drawn in
during operation must not fall below 6 °C (43 °F).
Any other use beyond that described shall be deemed inappropriate.
Observation of these instructions is also part of the correct use of
this water heater.
Any changes or modifications to this water heater void all warranty
rights.
3.3 Incorrect use
The following are not permitted:
- Do not heat anything other than potable water

This water heater must not be operated at ambient
temperatures in excess of 42 °C (107 °F) or below 6 °C
(43 °F).
If outside air is directly drawn in ensure, that the
water heater is isolated from its power supply when
the air temperature falls below 6 °C (43 °F).
3.4 Personnel qualification
DANGER Injury
Incorrect handling can result in severe injuries and
material losses. Inadequately qualified personnel
cannot assess the potential risks.
Have the installation, initial start-up, maintenance
and repair steps carried out only by the qualified
individuals specified in the respective chapters.
In the remainder of this manual, such qualified individuals will be
described as the "licensed installer."
3.5 Safety equipment

of the water heater. Dry, this water heater weighs 130 kg (290 lb).
Safety shoes/boots reduce the risk of
3.6 Particular risks
3.6.1 Electric current
WARNING Electric shock
Contacting parts that carry live power is associated
with a direct risk to life. Damaging the insulation or
individual components can result in a risk to life.
» If you detect damaged insulation, immediately
switch off the power supply and arrange for the
necessary repair.
» Have all electrical work carried out by a qualified
electrician.
3.6.2 Hot surfaces
CAUTION Burning
Contact with hot components can result in burning.
» When working near hot components, wear
protective clothing and gloves.
» The pipework connected to the hot water outlet of
the water heater can reach temperatures in excess
of 60 °C (140 °F).
3.6.3 Refrigerant
The water heater is filled with R134A refrigerant at the factory.
WARNING Freezer burn
Should the water heater leak refrigerant, avoid contact
with the refrigerant or breathing in any released
vapors. Immediately vent the room.
In normal water heater operation, the refrigerant is contained in
a sealed circuit.
