Brief Description of the Unit
• Casings of air handling units are made of galvanized steel sheets, which are powder painted. Mineral wool is used
for thermal insulation and sound attenuation. Unit cover panels are 15...20 mm thick. The air handling unit is in-
tended for ventilation of small-sized spaces (eg. single family houses, ats). The unit is designed to be mounted on
kitchen hood. As standard, the unit is designed for indoor placement. The operating temperature range for the unit
is -300C ... 400C, outdoor air temperature.
The air handling unit is not to be used to transport solid particles, even not in areas where there is a risk of
explosive gases.
• KOMFOVENT DOMEKT REGO 200VE(W) is equipped with a rotary heat exchanger, air lters, an electric air
heater, fans and automation control system, to ensure safe and efcient operation of the unit.
• Before you open the door, the unit must be switched off and the fans must have been given time to stop (up to 3
minutes).
• The unit contains heating elements that must not be touched when they are hot.
• To maintain a good indoor climate, comply with regulations and, to avoid condensation damage, the unit must never
be stopped apart from during service/maintenance or in connection with an accident.
• If the unit is placed in spaces with high humidity, condensation might occur on the surface of the unit when outdoor
temperatures are very low.

Final Inspection
After installation of the unit, a thorough inspection should be carried out. This should include inspecting the
inside of the unit and removing debris and tools, which may have been left behind by on site contractors. Replace
any panels, which may have been removed and close all access doors, ensuring that the door sealing gaskets
have not been damaged.
Maintenance
It is recommended to carry out routine maintenance of the air handling unit KOMFOVENT DOMEKT
REGO 200VE(W) 3 – 4 times per year.
All components inside the unit are easily detachable for cleaning. Don’t forget to unplug the cables out of
electric components and unscrew bolts from electric heater and rotary heat exchanger.

Installation and Maintenance Service Manual
Besides preventive maintenance inspection, the following operations should be performed:
1. Rotary Heat Exchanger Check. Inspection of the rotary heat exchanger is performed once per year. Free
rotation of the rotary heat exchanger, continuity 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
efciency of rotary heat exchanger will fall down. To reach maximal efciency, rotor must turn at least 8
times per minute. Polluted heat exchanger will decrease efciency. Clean heat exchanger with an air blast
or wash with tepid water. Check out water falling on the electric motor.
Heat Exchanger Washing. If rotor cleaning by compressed air is not effective, it can be washed with soap-
suds (11 Picture), or if needed – use degreasing soak for metal (aluminum) cleaning. Check out water falling
on the rotor’s electric motor and other automatics’ elements. In case if water got into details, they must be
urgently dry up. Leave rotor to dry in a warm place. Rotor can be connected only when it is absolutely dry.
Heat Exchanger Washing
2. Fans Check (once per year). Polluted fans decrease efciency.
Before performing any inspection work, check whether the unit is switched off from the
electric power supply.
Fans should be carefully cleaned with textile or soft brush. Do not use water. Do not break balance. Check
if direction of fan turns is right, because wrong direction of turns gives only 30% of rating. Check if fan freely
rotates and is not mechanically damaged, if impeller does not touch suction nozzles, fan does not spread
noise, the pressure tubes are connected to the nozzle (if required), mounting bolts are screwed.
3. Air heater check. Recommended to perform periodical inspection and cleaning of heater. Check the
plates of water air heater. The air heater is cleaned with hoover from supply air side or with air blast from
exhaust air side. If it is very dirty, wash with tepid water, which will not make corrosion of aluminium. Check
if position of return water temperature sensor is right. Check if electric air heater is properly xed, wires
connections are not damaged and heating elements are not bent. They can be damaged or bent due to
uneven heat or uneven and turbulent air direction. Check if electric air heater is clear of unnecessary
things and heating elements are not clogged, because this can cause unpleasant smell or in the worst
case – dust can start burning. Air ow through the air heater should be greater than 1,5 m/s. Heating
elements can be cleaned with hoover or wet textile.
4. Air Filter Clogging Check. Change air lters when air lter clogging is indicated. We recommend to
change lters at least twice per year: before and after heating season, or more*. If air handling unit is work-
ing in small speed, the lters must be checked on unit maximum speed. Filters are one time used. We do
not recommend cleaning them. Stop the air handling unit before changing lters.
* Clogged lters unbalance ventilation system, air handling unit uses more power.
