1.Tighten the fan fastening bolts.

2.Connect the power supply cable to the fan.

! WARNING

Risk of electric shock. Can cause injury or death.

Reconnect the earth ground cable to the sheet metal panel to prevent a potentially hazardous open circuit in case of loose or disconnected electrical wiring or a fan motor short circuit.

3.Switch on the circuit breaker.

4.Dispose of the old fans correctly.

6.2Inspect the Heat Exchanger—Annual

The efficiency of heat exchangers is sharply reduced by dirt and debris; retaining high efficiency requires regular cleaning. Use a vacuum cleaner, compressed air or a soft brush to clean the fins.

Do not bend the fins during cleaning—this will interfere with proper air flow through the unit.

Check heat exchanger on air side for soiling, damage and corrosion.

Check feed and return for correct function.

If necessary clean the air side.

Regularly check odor trap (external) for correct function.

Heat exchanger can be pulled out for improved cleaning.

Regularly visually inspect the water circuit for leaks.
