Manual & Electric Venting

Manual Venting Option:

Pole Eye and Pole – Replaces the standard crank handle to allow use of the Skylight Pole.

Electric Venting Option:

LWS Motor Kit – A motorized retrofit to existing manually vented skylights. To motorize manually vented models, retrofit the hand crank casing with a WLS Motor Kit. Includes electric motor, rain sensor and wall mounted control unit. The WLS is a hard-wired electric motor with wall switch control. Installation by a certified electrician is recommended. Each motorized window must have its own control unit. LWS Motor and Switch cannot be ordered separately. Optional wireless LWS remote controls are available, purchased separately.

LWS Remote Control – Optional replacement of wall mounted switch. For use with LWS Motorization Kit, RF (radio frequency) hand-held remote can control multiple venting skylights. Nine zones or “unit codes” are available to allow units to be controlled in groups and organized to your needs.

Safety Considerations

Skylights pose an inherent risk of injury or death from fall throughs, and the safety of others is of the utmost importance to VELUX.  VELUX recommends that the customer, building owner or manager use additional protection with the skylight such as an exterior or interior safety cage, to enhance long-term safety.  The building owner or manager is responsible for providing fall protection around the skylight in accordance with OSHA regulations.  VELUX also recommends that the building owner or manager restrict roof access only to personnel who have been cautioned as to the location of the skylights, and warned not to sit, step or walk on the skylights.
