5 Set-UP

5.1General Information

The unit must be installed indoors on a level, smooth and hori- zontal surface. The entire base of the frame should lie directly on the floor to ensure a good soundproof seal. If this is not the case, additional sound insulation measures may be necessary. If the device is installed on top of a built-under buffer tank, a surface that fully supports the base is required. The heat pump must be installed so that maintenance work can be carried out without being hindered. This can be ensured by maintaining a clearance of 1 m in front and to the left and right of the heat pump.

Never install the device in rooms subject to high humidity. Con- densation can form on the heat pump and air circuit if the humid- ity exceeds 50% and the external temperature is below

O °C.

If the heat pump is installed on an upper storey, the load-bearing capacity of the ceiling should be checked. On account of the acoustics, measures for isolating possible vibrations should also be very carefully planned in advance as well. Installation on a wooden floor is not recommended.

5.2Condensed Water Pipe

Condensed water that forms during operation must be drained off frost-free. The heat pump must be mounted on a level plane to guarantee proper drainage. The condensed water pipe must have a minimum diameter of 50 mm and should be fed frost-free into a sewer. Condensate should not be discharged directly into clearing tanks and cesspits because the aggressive vapours could destroy the evaporator.

5.3Sound

To prevent solid-borne sound from being transmitted to the heat- ing system, we recommend connecting the heat pump to the heating system using a flexible hose.

Installed air ducts should be sound-isolated from the heat pump to prevent the transmission of solid-borne sound to the ducts.

6 Installation

6.1General Information

The following connections need to be established on the heat pump:

Fresh and exhaust air

Flow and return flow of the heating system

Condensate outflow

Power supply

6.2Air Connection

ATTENTION!

Do not restrict or block the area around the air intake or outlet.

ATTENTION!

Only operate the heat pump with the air ducts connected.

The glass fibre reinforced concrete air ducts offered as accesso- ries are moisture-resistant and diffusion-free.

The sealing collar is used to seal the air ducts on the heat pump. The air ducts are not screwed directly onto the heat pump. Only the rubber seal comes into direct contact with the heat pump when the system is installed correctly. This guarantees easy as- sembly and disassembly of the heat pump and also ensures that solid-borne sound is well insulated.

If another type of air duct is used, observe the external and inter- nal dimensions as specified in the figure. Also ensure that the vi- bration and duct insulation are adequate.

If flange-mounted air ducts are used, connecting stubs are se- cured on the air inlet and air outlet sides of the evaporator with 4 M8 x 16 hexagon bolts in the threaded holes provided. When doing this, ensure that both air duct stubs only touch the insula- tion. There should be no contact with the external sheeting.
