FAN HEATER
TECHNICAL DOCUMENTATION OPERATION MANUAL

APPLICATION

LEO heaters make up a decentralised heating system. The air streaming through the heat exchanger filled with hot water is warmed up. Fan heaters are used for heating large volume buildings: general, industrial and public buildings etc.
The casing of LEO heaters is made from extended polypropylene EPP. LEO in special version ST has a casing made from powder coated steel. The devices LEO in special version INOX have casing and air blades made of austenitic stainless steel.
The devices are designed for indoor use where maximum air dustiness does not exceed 0,3 g/m3. Units are built using copper, aluminum and galvanized steel. It is prohibited to install units in the areas where environment inside can causes in rusting. The devices can not be used in an environment where there is oil mist.
Water heat exchanger could be supply by water or glycol solution up to 60%.

INSTALLATION

Fan heaters can be mounted to vertical or horizontal partitions in any position. During the montage, the minimal distances from the walls and ceiling have to be kept.
3.1. INSTALLATION –BRACKET 3.2. ASSEMBLY INSTRUCTIONS

3.3 U-PROFILES (optional) U-profiles should be mounted in corners as drawing shows. Is not allowed to screw profiles in other places.

CONNECTION DIAGRAMS

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 .
It is possible to connect up to 31 modules DRV and control them with one T-box controller .

DRV modules can be connected to the BMS (Building Management System).
WARNING: The connection must be carried out with 3-wire (recommended UTP) to connectors DRV IN

START-UP AND OPERATION

Guidelines for System Connection

• The connection should be executed in a way which does not induce stresses.
• It is recommended to install vent valves at the highest point of the system.
• The system should be executed so that, in the case of a failure, it is possible to disassemble the device. For this purpose it is best to use shut-off valves just by the device.
• The system with the heating medium must be protected against an increase of the heating medium pressure above the permissible value (1.6 MPa).
• While screwing exchanger to pipeline – connecting stubs has to be hold by wrench.

Start Up
 Before connecting the power supply check the correctness of connection of the fan motor and the controllers. These connections should be executed in accordance with their technical documentation.
 Before connecting the power supply check whether the mains voltage is in accordance with the voltage on the device data plate.
 Before starting the device check the correctness of connection of the heating medium conduits and the tightness of the system.
 The electrical system supplying the fan motor should be additionally protected with a circuit breaker against the effects of a possible shortcircuit in the system.
 Starting the device without connecting the ground conductor is forbidden.

Operation

• The device is designed for operation inside buildings, at temperatures above 0oC. In low temperatures (below 0ºC) there is a danger of freezing of the medium.

The manufacturer bears no responsibility for damage of the heat exchanger resulting from freezing of the medium in the exchanger. If operation of the device is expected at temperatures lower than 0º, then glycol solution should be used as the heating medium, or special automatic systems should be used for protecting against freezing of the medium in the exchanger.

• It is forbidden to place any objects on the heater or to hang any objects on the connecting stubs.
• The device must be inspected periodically. In the case of incorrect operation of the device it should be switched off immediately.

It is forbidden to use a damaged device. The manufacturer bears no responsibility for damage resulting from the use of a damaged device.

• If it is necessary to clean the exchanger, be careful not to damage the aluminium lamellas.
• For the time of performing inspection or cleaning the device, the electrical power supply should be disconnected.
• In case water is drained from the device for a longer period of time, the exchanger tubes should be emptied with compressed air.
• It is not allowed to make any modification in the unit. Any modification causes in warranty loss.

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 heat exchanger, if is it filled with dirt or dust. If necessary – use pressurized air stream to clean the exchanger’s lamellas,
  

• Check heat exchanger, if is it filled with dirt or dust. If necessary – use pressurized air stream to clean the exchanger’s lamellas,

• Check fan blades, in case of dirt use damp cloth and remove dirt,

• Check bracket installation,

• Check heat exchanger and hydraulic connection correctness,

• Check wires insulation,

• Check power supply,

• Check medium flow,

• Check levelling of the unit.

SERVICE AND WARRANTY TERMS

Please contact your dealer in order to get acquitted with the warranty terms and its limitation.
In the case of any irregularities in the device operation, please contact the manufacturer’s service department.
The manufacturer bears no responsibility for operating the device in a manner inconsistent with its purpose, by persons not authorised for this, and for damage resulting from this!

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.
For information on the collection system of waste electrical and electronic equipment, please contact the distributor.
REMEMBER:
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.
