7.4. Commissioning and maintenance
The maintenance interval is 6 months. It is advisable to have the unit serviced at the beginning (autumn) and at the
end (spring) of the heating season.
• Make sure that the heat transfer surfaces are clean and intact.
• Check the operation of the dampers. If necessary, lubricate with a silicone-based lubricant.
• Check that the turning direction of the actuator is the same as that of the dampers.
• Clean the heat recovery cube gently with a brush, compressed air or a vacuum cleaner. If the unit has
water drains, the coil can be cleaned with water and a mild detergent. NOTE! Do not use pressure
cleaning.
• Check and, if necessary, clean the condensation water discharge system, i.e., drip tray, piping and wa -
ter trap.
• Flush the piping and fill the water trap.
• Make sure that there are no loose pieces, debris etc., that could get into the fan impeller.
• Make sure that the electrical cables are intact.
• Make sure that the seals of the access door and plate heat exchanger are in place and intact. Close the
access door and make sure that every latch tightens properly.
CAUTION
If the unit is installed in a place where it is accessible to persons other than service
personnel, the handles of the access doors must be removed and locked in a safe place.
CAUTION
If the heat recovery chamber is pressurised, make sure that the fan has stopped before you
open the access door.
