6.8. Frost protection
The frost protection equipment must be inspected prior to the start of the cold seasons:
- Test thermostat function and settings (standard temperature setting: +5°C to +8 °C).
- Check all parts containing water or refrigerant for leakage.
- Check the condensate drain and siphon. Fill the siphon.
- Clean the condensate tray.
- Clean the fins with a soft brush or vacuum cleaner. Do not clean the fins with
compressed air.
-
Check all connections and pipeline systems for tightness.
6.9. Potential equalization / earthing
In order to prevent ignition sources caused by electrostatic charging, all non-conductive
connecting points must be equipped with potential equalization connections (flexible
connections, fan-motor unit). The entire unit must be earthed.
6.10. Motor overload protection
Protect the motor according to DIN EN 60204 / DIN VDE 0113 against overload.
Safety fuses and automatic circuit breakers do not provide adequate protection of the
motor.
Damage to the unit caused by insufficient motor protection is not covered by the
manufacturer's warranty.
6.11. Filters
When installing bag filters, ensure that the joint between the filter frame and the installation
wall is air-tight. Ensure that the filter pockets are not clamped or damaged, and that all filter
pockets can align themselves freely in the air flow.
At the filter side facing the door, there must be sufficient space so that the filter can be easily
removed and installed.
After changing a filter, attach and complete the filter label.
When using filters, observe the following:
•
Filters must be stored in a dry and dust-free room.
•
Do not use filters whose expiry date has lapsed.
•
Ensure that the newly installed air filter is not inadvertently contaminated by dust
from the old air filter.
