SERVICE HERU®
Duct cooling coil
The safety switches must be switched off and locked after the unit has been switched off
before starting any service work.
Function
The air cooler uses water to cool the supply air to the desired outgoing temperature. The
cooler consists of a number of copper pipes with aluminium slats. For circulation and
regulation of the water, the cooler is usually equipped with a shunt group. Condensation
usually forms on the cooler, which is therefore fitted with a tray and drainage. A water
trap with a non-return valve should be connected to the drainage.
Check
1. That the front surface of the coil is not dirty.
2. That the pump is running and that the water is circulating and has the correct
temperature for the season.
3. That the slats are intact.
4. That the coil is not damaged and is not leaking.
5. That the drainage tray is free of contamination.
6. That the water trap is working and is full of water
Corrective action
1. Clean with a vacuum cleaner fitted with a soft brush.
2. Check the pump for damage. Make sure the sensor is working.
3. Adjust the slats with a “slat comb”.
4. Turn off the water and empty the system through the coil’s drain valve. Change the
coil.
5. Clean. If necessary, adjust the coil’s incline toward the condensation pipe.
6. Make sure the ping-pong ball can move freely and is not stuck.
