Cleaning and Inspection of Rotary Heat Exchanger
Inspection of the rotary heat exchanger is performed once per year. Free rotation of the rotary heat exchanger, con-
tinuity of the rotating belt, absence of damages of the rotor drums and the seal gasket are checked. It is necessary
to check the stretch of belt. Free belt will slide and the efficiency of rotary heat exchanger will fall down. To reach
maximal efficiency, rotor must turn at least 8 times per minute. Polluted heat exchanger will decrease efficiency.
Clean heat exchanger with an air blast or wash with tepid water. Check out water falling on the electric motor.
If the fabric drive belt is worn or substantially fouled, it should be replaced. Do not lubricate it! Contact service
personal.
VERSO-RHP air handling units with integrated heat pump
•
Air handling unit with integrated heat pump operation range is from -15 to 35 °C. At lower temperatures (from
-15 to -30 degrees) heat pump system is switched off. The unit performs air ventilation with regeneration func-
tion, and air is heated with additional heater (if provided).
•
Carefully, high pressure inside (up to 42 bar).
•
Emergency pressure on which the heat pump is stopped: low pressure 1.5 bar, high pressure 42 bar.
•
For stable operation of the device, set the device controlling mode under the outdoor temperature (duct or
room).
•
Inside the unit is refrigerant R410A, friendly to environment.
• Before commissioning, make sure that the air handling unit is filled with refrigerant. This can be done by look
-
ing through the moisture indicator.
•
The unit is equipped with moisture indicator. At high moisture content of the system, it must be cleaned,
changed the filter and re-filled with refrigerant.
•
The unit washing, cleaning, maintenance is carried out as well as any other type of device described in this
manual.
• Device information sticker of the used refrigerants is applied near to the high-and low-pressure filling valve.
Sticker is seen when doors are opened.
•
In heating mode supply air temperature can range due to frozen evaporator. Therefore, this unit is not rec-
ommended for use as a basic unit for heating, at low outdoor air temperatures use with a secondary heater.

2.3. Rotary Heat Exchanger in VERSO-R/RHP Air Handling Units
The heat exchanger actuator mechanism is oiled with synthetic solution; therefore there is no need to oil mechanism
during its exploitation.
It is important to make sure that the rotary heat exchanger mechanism
is clean: to change the filters installed in the air handling unit on time, to
perform periodical heat exchanger cleaning. The temperature efficiency of
a dirty heat exchanger can diminish considerably.
