Important information

2.1

General safety precautions

Warning! Risk of personal injury! Children are not permitted to play with the product.
Caution! The heat pump must be installed by authorised installation engineers and the installation must
follow the applicable local rules and regulations as well as these installation instructions.
Caution! This product is not intended for persons (including children) with reduced physical, sensory or
psychological capacity, or who do not have knowledge or experience, unless supervised or they have
received instructions on how the apparatus functions from a safety qualified person.
Caution! When cooling it is important to limit the lowest flow line temperature to prevent condensation.
2.2

Refrigerant

2.2.1 Fire risk
The refrigerant is not combustible or explosive in normal conditions.
2.2.2 Toxicity
In normal use and normal conditions the refrigerant has low toxicity. However, although the toxicity of the refrig-
erant is low, it can cause injury (or be highly dangerous) in abnormal circumstances or where deliberately abused.
Warning! Risk of personal injury! Spaces in which heavy vapour can collect below the level of the air must
be well ventilated.
Refrigerant vapour is heavier than air and, in enclosed spaces below the level of a door for example, and in the
event of leakage, concentrations can arise with a resultant risk of suffocation due to a lack of oxygen.
Warning! Risk of personal injury! Refrigerant exposed to a naked flame creates a poisonous irritating gas.
This gas can be detected by its odour even at concentrations below its permitted levels. Evacuate the area
until it has been sufficiently ventilated.
2.2.3

Work on the refrigerant circuit

Caution! Work on the refrigerant circuit must only be carried out by a certified engineer!
Caution! When repairing the refrigerant circuit, the refrigerant must not be released from the heat pump -
it must dealt with in the appropriate way.
