Operation and maintenance instructions
1. For rotary heat exchanger (RX) units, check the brush seals on the rotary heat exchanger along the
perimeter in contact with the frame:
If necessary, bring the brush seals closer to the exchanger to ensure good sealing.
2. For RX units, check the tension of the driving belt on the rotating heat exchanger. If there is no tension or if
the belt is damaged, please, contact the service department for a belt replacement.
Ideally the heat exchanger should be cleaned using vacuum cleaner with a soft nozzle to prevent damaging the air
passages in the rotor. Turn the rotor by hand to enable you to vacuum clean its entire surface. If the heat exchanger is
substantially fouled, it can be blown clean with compressed air.
3. For plate heat exchanger (PX) units:
• Clean the drain pan
• Clean the inside of the bypass. To access the interior of the bypass it is necessary to force it open, proceed as follows:
place a jumper between terminals IN3 and +12V on the TAC circuit board. The bypass is now open, regardless of the
temperature conditions.
• Remember to remove the jumper between terminals IN3 and +12V once cleaning of bypass is done.
• Always clean against the direction of the airflow.
• Cleaning must only be done by blowing with compressed air, vacuum cleaning with a soft nozzle or through
wet cleaning with water and/or solvent. Before you begin cleaning, cover adjacent functional sections to protect them.
If cleaning solvent is used, do not use solvent that will corrode aluminium or copper.
4. Fan maintenance:
Check again whether the power supply is shut down and fans are not running.
Inspect and clean the fan impellers to remove any dirt deposits, be careful not to alter the impeller balance
(do not remove balancing clips). Check the impeller to make sure that it is not out of balance. Clean or brush off the
fan motor. It can also be cleaned by carefully wiping it with a damp cloth that has been dipped in a solution of water and
detergent. Clean the fan space, if needed. Remove the fans if necessary.
5. Check seals on the unit:
Ensure that the side access panels are fully closed and that the seals are intact. Replace if necessary.
