Required maintenance material (not included in the scope of delivery):

☐ A suitable water-free, heat-resistant lubricant

☐ Talcum, petroleum jelly or wax for maintaining the seals

DANGER

Danger to life due to electric shock or electric arc if live components are touched

• Switch off the inverter and wait at least 15 minutes before opening it to allow the capacitors to discharge

completely.

• Disconnect the inverter (see Section 4, page 26).

Procedure:

1. Check whether the seals in the sealing area show any damage.

If seals are damaged, contact us (see Section 9 "Contact", page 68).

2. Apply talcum, petroleum jelly or wax to seals. This will prevent frost damage.

3. After removing the side panels: check whether the side panel seals display any damage in the sealing area.

If seals are damaged, contact us (see Section 9 "Contact", page 68).

6.4.2.7

Checking the Latches, Door Stops and Hinges

Required maintenance material (not included in the scope of delivery):

☐ A suitable, water-free and heat-resistant lubricant, e.g. WD40

☐ Non-greasing antifreeze agent, e.g. PS88
