authorised by the manufacturer.

2.3 Personal protective equipment

There is a risk of cutting your hands on sharp edges

of the unit.

 Wear cut-resistant protective gloves during trans-

port.

2.5 Disposal

Environmentally hazardous media

Improper disposal of environmentally hazardous me-



 Collect media safely.

 Dispose of the media in an environmentally sound

manner in accordance with to the local regula-

tions.

2.6 Avoid material damage

The ambient air at the heat pump’s installation site, as

well as the air drawn in as a heat source, must not

contain any corrosive components!

Constituents such as

 Ammonia

 Sulphur

 Chlorine

 Salt

 

can cause damage to the heat pump, which can even

result in the complete failure/total loss of the heat

pump.

Decommissioning/draining the heating

If the system/heat pump is decommissioned or drained

        

the condenser and any heat exchangers have been

drained completely for the event of freezing temper-

atures. Residual water in heat exchangers and con-

densers can result in damage to the components.

 Completely drain the system and the condenser,

and open vent valves.

 Blow them clear with compressed air, if required.

Improper action

Requirements for minimum scale and corrosion dam-

age in hot water heating systems:

 Professional planning and commissioning

 Closed system with regard to corrosion

 Integration of an adequately dimensioned pres-

sure maintenance

 Use of demineralized water heating water or

VDI 2035 water

 Regular servicing and maintenance

If a system is not planned, commissioned and operat-

ed in accordance with the given requirements, there

will be a risk of the following damage and malfunc-

tions:

 Malfunctions and failure of components, e.g.

pumps, valves

 Internal and external leaks, e.g. at heat exchangers

 Reduction in cross-section and blockages in com-

ponents, e.g. heat exchangers, pipes, pumps

 Material fatigue

ature can be carried out using an electric heating ele-

ment, which is activated by the heat pump controller

with a tensioning strap.

3. Transport the heat pump module to the installa-

tion site.

5.4 Installation

CAUTION!

In the air outlet area, the air temperature is

approx. 5 K below the ambient temperature.

Under certain climatic conditions an ice lay-

er can therefore develop in the air outlet area.

Install the heat pump so that the air blower

does not discharge into footpath areas
