Application
The fan heater is approved for flammable areas and may be used, for instance, in livestock barns, woodworking workshops, etc. The
fan heater is portable, but can also be permanently installed. If the fan heater is permanently installed, an isolating switch with a
contact gap of at least 3 mm must be provided. The fan heater must be easily accessible for cleaning and service. The fan heater has
been tested for electrical safety and has been EMC tested by SEMKO. The fan heater is CE marked. Degree of protection: IP65.
When not in use, the fan heater must be stored in a dust-free location.
Caution
• Don’t use the fan heater closer than 0.5 m to combustible matter.
• The fan heater must not be located so that combustible substances can collect on or near the fan heater.
• On permanent installation without external control, the minimum installation dimensions should be as shown in on page 7.
• On permanent installation with remote control, the fan heater should be installed at a height of at least 1.8 m above the floor.
Before starting
Before starting the fan heater, check that the fan, heater element and protective grille are free from dust and dirt. The fan heater has
neutral point tripping, and the black button is used for starting:
• When the fan heater has been switched off.
• After a power cut.
• After the temperature limiter has tripped.
Accessories
RST control unit with start and stop buttons for remote control, e.g. if the fan unit is installed high up on a wall

Service/Maintenance
Clean the fan heater at regular intervals, since dust and dirt may cause overheating and involve the risk of fire. The fan heater has a
built-in temperature limiter with manual reset, which is intended to trip the power supply in the event of overheating. If the tempe
-
rature limiter has tripped, isolate the power supply to the fan heater and correct the fault. The temperature limiter is reset automati
-
cally when the fan heater has cooled down.
