The wire connecting the motor to the controller is supplied
with a pre-mounted 4-pole connector (Tyco MATE-N-LOK). The
other end of the wire is equipped with bushings and should be
connected to the drive motor terminals (U, V, W, PE).

4.7.2 Tension of the drive belt of the rotary exchanger
Tension the drive belt by pressing with a moderate finger
strap at a distance of about 100mm from the axis of the
pulley. The belt deflee should be 15-30mm – as in the dia-
gram below.
In case of deflection the belt should be shorten.

4.7.3 Operation of the rotary exchanger
The rotary exchanger should be inspected every 6/12
months. Aluminium laths get dirty.
Before cleaning rotary exchanger sections, the neighbo-
uring sections should be secured.
Clean with a vacuum cleaner with a soft suction nozzle on
the side of air inlets or blow through with air in the direc-
tion opposite to the airflow in the exchanger. The drive
belt of the rotary exchanger is an operating element and
should be replaced if an incorrect tension is noticed.
The rotary exchanger in the standard version of the unit is
equipped with a spare belt. If the exchanger design does
not include a spare rotor drive belt, contact service to de-
termine its type and proper length.
4.8 PR cross-flow exchanger / CPR high efficiency hybrid heat re-
covery system
The cross-exchanger allows heat recovery from the outlet
air with an efficiency of up to 75% and the high efficiency
hybrid kit up to 92%.
The main components are: cross-flow exchanger or hybrid
exchanger, by-pass, two-section damper, condensate tray
and condenser. The cross-flow exchanger is made of thin
extruded aluminium plates, which form ducts for supply
and exhaust air. The flow of warm air extracted from the
room, flows through the ducts of the exchanger, heating its
plates. The intake air stream flows in a perpendicular direc-
tion to the outlet air stream, taking heat from the exchanger
plates.
Heat recovery on the cross-flow exchanger does not require
any energy supply from outside, the exchanger has no mo-
ving parts, which ensures its high reliability. The intake and
outlet air streams are separated from each other. The inter-
nal tightness is determined at 99.5-99.9%
