DANGER: RISK OF BURNING/SCALDING
WARNING
Provide adequate measures to prevent that the unit can be used as a shelter by small
animals. Small animals that make contact with electrical parts can cause
malfunctions, smoke or fire.
WARNING
Some sections of the refrigerant circuit may be isolated from other sections caused
by components with specific functions (e.g. valves). The refrigerant circuit therefore
features additional service ports for vacuuming, pressure relief or pressurizing the
circuit.
In case it is required to perform brazing on the unit, ensure that there is no pressure
remaining inside the unit. Internal pressures need to be released with ALL the service
ports indicated on the figures below opened. The location is depending on model
type.
WARNING
▪
Only use R32 as refrigerant. Other substances may cause explosions and
accidents.
▪
R32 contains fluorinated greenhouse gases. Its global warming potential (GWP)
value is 675. Do NOT vent these gases into the atmosphere.
▪
When charging refrigerant, ALWAYS use protective gloves and safety glasses.
WARNING
The discharge pipes from the pressure relief valves MUST terminate in a safe and
visible position without forming any risk to persons in the vicinity.
WARNING
▪
Discharge piping, tundish, drain valves, etc. MUST be positioned away from any
electrical components.
▪
The discharge pipe away from the tundish MUST terminate in a safe, visible
position without forming any risk to persons in the vicinity.

Do NOT install shut-off valves between the expansion relief valve and the
domestic hot water tank.
