Frequently Asked Questions

Where should I take the unit for installation and major repairs?

Contact an authorized service man for repair maintenance or an installer for setup.

What are key safety concerns regarding electrical connections?

Always perform grounding and use a dedicated, properly installed circuit breaker to prevent electric shock and fire.

Clean the filters every two weeks; failure due to dirty filters can damage the appliance or cause operational accidents.
