2. SAFETY STIPULATIONS
Connection of the air heater to the power supply must be performed by a qualified electrician and must be in
conjunction with local prescribed standards and safeguarded accordingly.
• The air heater is protected against overheating by means of a build-in maximum thermostat with a fixed value of
85°C and will reset automatically.
• Switching on the heater is to be performed by a special main switch or a suitable power plug – wall socket
combination.
• The air heater must have separate fuses in the main circuit.
• The air heater is suitable for either wall or floor mounting in normal surroundings with ‘not combustible materials’.
This in compliance the directives according to the NEN 1010. Do not use solvents or light inflammable materials in
the vicinity of the air heater.
• Touching of hot heating elements must be prevented from occuring.
• Operation must only be executed by trained personnel who have read and will adhere to the operating and
safety instructions.
To prevent fire hazards the rear end of the heater must be placed
110 mm from the wall
and 300 mm at the front
and 100 mm on both sides
and minimum 110 mm at the top
When commencing maintenance or other jobs
Let the heater cool down first and switch of Voltage at the mains

Safety
Maximum safety thermostat 85°C (automatic) in combination with a
3-pole magnetic switch (coil voltage: 400 VAC).
Mounting
The mounting bracket is suited for wall mounting and has the ability
to hold the heater at a variety of angles.
Ambient thermostat
The heater has been fitted standard with terminals (pos. 1 and 2,
see electrical wiring diagram) for connecting an external ambient
thermostat. This thermostat must be able to switch the rating of the
heater (400 Volts)
Motor thermostat
Preheating and cooling down takes place with the aid of a motor
thermostat. When the heater is switched on it first preheats before
the ventilator starts running.
Additionally when it is switched of by an ambient thermostat the
heater will leave the ventilator running until the heater has cooled
down enough for the motor thermostat to switch it off.
