5.1. Maintenance Safety

• Keep components in good condition. Follow the maintenance
procedures.
• Ensure the service area is clean, dry, and has sufficient
lighting.
• Do not modify any components without written authorization
from the manufacturer. Modification can be dangerous and
result in serious injuries.
• Shut down and lock out power before maintaining
equipment.
• All electrical maintenance must be performed by a qualified
electrician in accordance with all applicable local codes and
standards.
• When the power is locked out, fans can still be dangerous
because of potential "windmilling." Always block the
impeller/blade before working on any moving parts.
• After maintenance is complete, replace all guards, service
doors, and/or covers.
• Use only genuine Keho replacement parts or equivalent. Use
of unauthorized parts will void warranty. If in doubt, contact
Keho or your local dealer.
