installation and every additional adjustments of the device it is necessary to
familiarise with the content of the manual for use and maintenance.
DANGER
Connecting the device to the power source can only be performed by a qualified
installer in a voltage-free state. The cord has to be accessible and the socket
must be of such type which enables the cord to be pulled out in a simple manner.
CAUTION
The heat pump must not be obstructed, objects must not be laid up against it.
Free access to the device must be provided at all time. If during the operation of
the heat pump the water temperature exceeds 75°C, the service department has
to be notified.
4.3 Safety list: Coolant R-134a
4.3.1 Identification
The operating agent of the device is the hydrofluorocarbon HFC 134a. The coolant is not toxic,
flammable or explosive, it is not harmful to the ozone, but it is heavier than air which can cause
the extrusion of air from the room. The consequence could be a lower concentration of oxygen
in the air; but because of the very low quantity of the coolant in the device, there is no real
hazard for health. A lower concentration of oxygen can only occur in rooms smaller than 10 m
3
which are not ventilated and are underground where the coolant, which is heavier than air, can
remain for a longer period of time. Despite this, we recommend reading the safety list of the
coolant manufacturer and follow its instructions.
4.3.2 Danger mark
DANGER
Risk of situations which can lead to serious physical injuries.
1. Risk of endangering health:
The coolant fumes are heavier than air. The coolant can displace the air in the room
and the lack of oxygen can cause dizziness, loss of consciousness or even suffocation.
Liquefied gas: Contact with the liquid can cause serious frostbite and damage to the
eyes.
2. Product classification: This coolant is not characterised as a product “dangerous to
health/harmful” in accordance with the EU regulations.

4.3.4 First aid
1. In case of inhalation: Remove the person from the contaminated room and bring them
outside. If the person does not feel well, take them to the doctor.
2. In case of contact with skin: Frostbite is treated the same as burns. Thoroughly rinse
with clean water and do not remove clothing (danger of adhesion of clothing with the
skin). If skin burns occur, call the doctor immediately.
