1. APPLICATION
LEO EL heaters make up a decentralised heating system. Fan heaters
are used for heating large volume buildings: general, industrial and
public buildings etc. The devices are designed for indoor use where
maximum air dustiness does not exceed 0,3 g/m

. INSTALLATION
1. Fan heaters can be mounted to vertical or
horizontal partitions. During the montage, the
minimal distances from the walls and ceiling
have to be kept.
2. U-profiles should be mounted in corners as
drawing shows. Is not allowed to screw profiles
in other places.

:
When connecting DRV modules to the T
-
box controller or BMS, you
have to binary set addresses on each (each DRV must have individual
address) DRV module by DIP-switch SW1. To address modules check if
the power supply is turned off, than set then the addresses as shown in the
table, than turn on the power supply .

UP AND OPERATION
Start-up
•supply and controls have to be connected as shown in technical manual
•before connecting supply check that current is same as on the nameplate
•start-up without grounding cable is forbidden
Operation
•unit designed to indoor operation
•never place any things on the casing while operating
•unit should be serviced periodically; in case of failure the unit should be
switched off immediately
Never operate a failure unit. The producer does not take any
responsibility for damages caused by failure operation.
Switch off the electrical supply while servicing or cleaning.
Periodic inspections
To keep proper technical parameters Flowair recommends periodic
service (every 6 months) of fan heaters on behalf of the user.
During inspections user should:
 Check heating elments , if is it filled with dirt or dust. If necessary - use
industrial vacuum cleaner or pressurized air stream to clean the
exchanger’s lamellas. Excessive dirt on the heaters can cause
permanent loss of the rated parameters,
 Check fan blades, in case of dirt use damp cloth and remove dirt,
 Check bracket installation,
 Check wires insulation,
 Check power supply,
 Check levelling of the unit.

For information on the collection system of waste electrical
and electronic equipment, please contact the distributor.
R E M E M B E R :
Do not dispose of used equipment together with other waste! There
are financial penalties for this. Proper handling of used equipment
prevents potential negative consequences for the environment and
human health. At the same time, we save the Earth's natural
resources, reusing resources obtained from the processing of
equipment.
Running a business without harming the environment and
observing the rules of proper handling of waste electrical and
electronic equipment is a priority for Flexiheat.
The symbol of the crossed out wheeled bin placed on the
equipment, packaging or documents attached means that the
product must not be disposed of with other wastes. It is the
responsibility of the user to hand the used equipment to a
designated collection point for proper processing. The symbol
means at the same time that the equipment was placed on the
market after August 13, 2005.
