WARNING !

Before any maintenance, please switch AC and DC power off to avoid risk of

electronic shock.

In order to ensure normal operation of the inverter, please check the unit regularly.

Check that all terminals, screws and cables are connected and appear as they

did upon installation. If there are any impaired or loose parts, please contact your

solar installer immediately. Ensure that there are no foreign objects in the path of

the heat outlet and keep the unit and it’s surroundings clean and tidy at all times.
