The RVK series is designed for installation in ducts. Duct connected wet room applications of the fan are
possible due to the air tight casing and the IP 44 rated terminal box. We recommend a period of continued
ventilation with dry air for wet room applications.The fans have backward-curved blades and external rotor
motors. The FK mounting clamp facilitates easy installation and removal, and prevents the transfer of vibra-
tion to the duct. The fans can be speed-controlled via a stepless thyristor or a 5-step transformer. To protect
the motor from overheating the models have integrated thermal contacts with manual reset. The casing is
manufactured from PP fibreglass reinforced plastic which gives the fan a less leckage casing.

Storage
»
Store the fan in the original packaging dustproof, dry and protected against weather.
»
Avoid effects of extreme heat or cold.
»
Please observe the storage position to the carton labels!
CAUTION
Hazard due to loss of function of the motor bearings!
» Avoid storing for too long time (recommendation: max. 1 year).
» Before installation, check proper function of the motor bearings
4.2
Transport
WARNING
Hazard of impact if the circular duct fan falls down!
»
Transport the fan carefully!
WARNING
Electrical hazard from damaged connections
» Do not use the terminal box or rotor for transport.
»
Transport the fan in its original packing material.
»
Avoid shocks or impact.
