GENERAL
Always read the Safety Instructions chapter of these operating instructions before putting the
heater into operation.
Even loss of life and loss of property can result from nonobserving the following instructions or
the valid national and international safety regulations.
Installation, electrical connection, commissioning and maintenance are only to be carried out
by authorised personnel and in accordance with requirements and current legislation. There
should be enough space provided for a safe working on service and maintenance.

SAFETY
2.1 Safety instructions
Caution: To avoid possible electrical shock, ensure the power is turned off before attempting
to wire. All wiring must be in accordance with local electrical codes. This equipment requires a
ground as precaution against electrical shock.
Basic precautions should always be followed to reduce the risk of fire, electric shock, and
injury to persons.
- Disconnect all power supplies before working on circuit.
- Do not heat air containing combustible materials.
- Mount heater out of reach.
- Install at least 2ft. (61 cm) from fl oor except 40 - 60 kW at least 8 ft. (2.4 m) from fl oor.
- Do not use outdoors.
- Do not insert or allow foreign objects to enter any ventilation or exhaust opening as this may
cause an electric shock or fire, or damage the heater.
- Do not block air intakes or exhaust in any manner.
- Heater contains arcing and sparking parts. Do not use it in areas where gasoline, paint, or fl
ammable liquids are used or stored.
- Use this heater only as described in this manual. Any other use not recommended by the
manufacturer may cause fire, electric shock, or injury to persons.
- Connect only to the voltage and frequency specified on the nameplate.
- Wire used to connect to the heater should have insulation rated to at least 75°C.
- Connections are to be made as shown on the wiring diagram

- Check out the fuses carefully. Beware of the sufficient power and amperage.
- A disconnecting means and ground must be provided in accordance with the National
Electrical Code.
- An optional integral thermostat may be installed to control heating element and fan. If so
equipped, the thermostat range is approximately 55°F to 105°F.
- Check out the contactor if it is working properly in threephase models.
Hot Furface: The surface temperature of the heater may rise up to temperatures which will
cause inquiry. Do not touch the surface while the heater is operating. In case of maintenance
or contact must, wait at least 2 hours after the unit is disconnected for the unit cool down .
2.2. Correct use
Heater will not operate.
• Make sure installation instructions and wiring diagram were followed.
• Disconnect switch or main circuit breaker may be in off position.
• Check for proper control voltage.
• Automatic or manual reset thermal cutout(s) may have opened due to overheating. Let unit
cool before resetting manual cutouts. Determine and correct the cause for overheating.
The unit is designed for heating air in closed areas. Do not intent to use the unit for other
applications.

OPERATING PRINCIPLE
COMPONENTS
• LOUVERS: Louvers are discharge air deflectors, either adjustable or nonadjustable, that
change or route the air flow
• HEATING COIL: convert electrical energy to heat by passing electrical current through a
specifically designed resistance wire. Constructed of spiral wound resistance wire, surrounded
by an insulating power , encased in a metal enclosure. Either Monophase or Threephase
types can be provided upon by request.
• FAN (FAN BLADE): is a propeller type device, used to move the air through the unit heater.
Unit heaters discussed in this manual are directly coupled to an electric motor. They are not
belt driven.
• MOTOR:are permanently lubricated electrical devices that rotate the fan to move the heated
air from the heater to the space. When the unit heater wattage is over loaded one or more
CONTACTORS are employed to switch the electrical current to the elements and / or
the motor. Usually a thermostat or fan delay will control when the contactor is energized.
• OVER TEMPERATURE LIMIT: is a normally closed temperature sensing device, located on
or in close proximity to the element, designed into the heater to open f an abnormally hot
condition occurs. Abnormally hot conditions are usually the result of a loss of moving air
across the element. Frequent causes of over temperature limit opening are; blocked inlet or
discharge, motor stoppage and loose fan.
5 APPLICATION AND INTENDED USE
The units are designed for heating air in closed areas. Heaters can be mounted for horizontal
or vertical air flow.
Typical Application Areas:
 Factories
 Warehouses
 Garages
 Stores
 Power Stations and Aircraft Hangers
 Agricultural Barns
 Green Houses
 Industrial assembly areas
 Enclosed outside smoking areas.
 Wall type or ceiling mounting bracket for horizontal or vertical air flow or any position
between.

- Do not heat air containing combustible materials
- Do not use outdoors
- Heater contains arcing and sparking parts. Do not use it in areas where
gasoline, paint, or fl ammable liquids are used or stored.
- Use this heater only as described in this manual. Any other use not
recommended by the manufacturer may cause fire, electric shock, or injury to persons.
6 PACKAGING, HANDLING, STORAGE
The units are packed in carton boxes and made ready for shipments on pallets. It is
essential that great care is exercised when handling the unit. When handling the equipment,
care should be taken with corners and edges and that the weight distribution within the unit is
considered.
The units should be stored indoors away from humidity.

COMMISSIONING
 For the first-commissioning it is recommended to use our specialist personnel
7.1. Installation
HEATER LOCATION: Unit heaters should be located along outside walls to provide
perimeter air circulation. The discharge air should wipe the walls without blowing directly on
them.
a. Small rooms - can be heated by one or two units. Locate the unit heater(s) to provide
circular air movement within the space.
b. Large rooms - requiring multiple unit installations. Units should be located so that the
discharge air from one unit supports the discharge from another unit and provides a circular
air movement.

7.3. First Start up and controls
1- Place the fan switch to ON position
2- Set the temperature control thermostat to a setting below the temperature
3- Energize the heater electrical supply circuit
4- The heater fan should come on but the heater should remain off
5- Place the fan switch to OFF position
6- The fan should go off
7- Set the temperature control thermostat to a setting above the current room temperature
8- The heater should come on and the fan should energize approx. 1-2 minutes. If the room
temperature is high or the heater is mounted too close to ceieling or walls the unitmay cycle
on the thermal high limits of the motor and/or heater
9- Check out and repost any unusual or questionable operating characteristics, such as noise,
vibration ..etc
10- Set the fan switch and temperature control on desired operating positions
7.4. Operation
1- Before the unit is energized, the discharge louvers should be be adjusted for desired air
deflection
2- Perform the operation steps for the applicable temperature control option
2- Place all switches in their normal operating position and place the unit heater in service.
8 SPARE PARTS
All replacements must be factory supplied to ensure safe heater operation. PITSAN assumes
