Final Inspection; Maintenance - Komfovent DOMEKT REGO 400VE-B Manuel D'installation Et De Maintenance

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.
Heating coil connection
service work. When carrying out the installation of heater pipes, make sure that hot water supply is completely
disconnected. Before start-up of the air handling unit, the heater system should be filled in with water. Glycol is
used in the air handling units with coil heat exchanger. Never pour glycol down a drain; collect it in a receptacle
and leave it at a recycling centre or the like. Glycol is highly dangerous to consume and can cause fatal poisoning
or damage the kidneys. Contact a doctor! Avoid breathing glycol vapour in confined spaces. If you get glycol in
your eyes, fush them thoroughly with water (for about 5 minutes).

MAINTENANCE

It is recommended to carry out routine maintenance of the air handling unit KOMFOVENT DOMEKT REGO
400VE(W) 3–4 times per year. Extracting unit elements (see 17 Picture). Cables must be disconnected when
extracting electric heater and rotary heat exchanger.
During inspection, the following operations should be performed:
1. Rotary heat exchanger check. Inspection of the rotary heat exchanger is performed once per year. Free rota-
tion 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 efficiency
of rotary heat exchanger will fall down. To reach maximal efficiency, rotor must turn at least 6 times per minute.
Polluted heat exchanger will decrease efficiency. Cleaning can be performed by compressed air or soapsuds.
Check out water falling on the rotor's electric motor.
Rotor cleaning. If rotor cleaning by compressed air is not effective, it can be washed with soapsuds
(18 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.
If water heater build in.

When operating air handling unit in the temperatures lower than 0 °C, it is
necessary to use glycol additionally or assure the reversible heating agent
temperature more than 25 °C.
It is important to maintain air heaters and coolers cleanliness; that is to
change filters installed in the air handling unit on time. If the air heater or
