Before start-up of the device, please read the Original Instruction Manual carefully, taking time to ensure full 
understanding: 
The manufacturer and retailer are not liable for the loss of health of persons or animals caused by: 
- usage of the equipment contrary to its foreseen use,
- usage of the equipment not in line with the original instruction manual,
- usage of the equipment contrary to fire and occupational safety provisions in force.

1. General rules

1.1. Foreseen use 

Type M and MP air heaters are foreseen for the heating and ventilation of rooms in which people remain or work. Type M 
heaters are equipped with axial ventilators, while type MP heaters are equipped with radial ventilators. 

1.2. Hazards stemming from improper heater use

 

The hot air chamber is equipped with safety devices that have been checked and tested. 
Improper use of the device can be hazardous to the persons making use of it, and possibly cause damage to components 
connected to the same electric circuit. 
Persons installing, using or servicing the heater should proceed in accordance with this Original Instruction Manual. 

Safety indications 

WARNING!

 

This is an indication of a potential hazard. Seeing this symbol, one should pay particular attention to information found 
below it. Failure to observe remarks indicated with this symbol may lead to damage to the heater or even to personal 
injury.

 

IMPORTANT!

 

This is an indication of the requirement to read the information found after it very carefully, as this will contribute to safe 
use of the device.

 

1.3. General indications

 

Air heaters with heat exchangers may be used in rooms, in which people remain.

 

WARNING!

 

Never install the heater in any room, in which there is any risk of explosions.

 

WARNING!

 

Exhaust fumes may cause a fire. Always maintain a safe distance to combustible materials.

 

1.4. Rules of safe operation 

The heater with a heat exchanger burns light fuel oil or diesel oil in a closed combustion chamber. The exhaust fumes are 
led to the outside through the chimney. Warm air is blown out by the ventilator. The ventilator is covered with a protective 
mesh on the air intake.

 

WARNING! 
Never use the heater without the ventilator safety mesh, as this may cause damage to persons and objects. 
IMPORTANT! 
The air intake and output openings must be uncovered at all times. 
WARNING! 
If the exhaust gases are directed straight towards any combustible material, this may cause a fire. 
WARNING! 
Before commencing any repairs or cleaning of the heater, remove the electric plug from the grid socket. Use the 
heater only as it is supposed to be used, meaning, solely and exclusively for heating and ventilation. 

1.5. Recommendations for the user 

The heater should be operated by a person who, before using the device, had thoroughly acquainted themselves with this 
Original Instruction Manual.
