1.4. Electrical equipment

•Any work extending beyond the scope of equipment maintenance must be performed by a specialist

only.

•Always follow local- and national regulations.

•The heater must always be connected to the mains electrical supply via an earthed socket.

•Keep the socket within reach.

•Always disconnect the appliance from the mains before performing any work on it.

•Never remove the safety grill while the heater is active or could be activated.

•Before starting up the appliance, examine all electrical wiring for any visible defects.

•Change any damaged wiring before switching on the appliance.

•Never remove the plug from the socket while the heater is active.

•Always allow the heater to cool down.

•Never use the heater while any component is missing.

•Have any plug devices that are damaged or destroyed replaced by a qualified electrician.

•Do not pull the plug out of the socket by the flex.

•Covering electric motors can cause high temperatures to build up, which can destroy the electrical

equipment and cause fires.

1.5. Maintenance

Always disconnect the appliance from the mains before working on the electrical

equipment!

Repairs should only be carried out by persons who have the training, knowledge or practical experience

to ensure that the repair is done properly.

Maintenance, repair and cleaning work should only be carried out with the drive switched off and the

motor idle. The same applies to the rectification of functional defects.

Wear protective gloves if there is a danger of injuring your hands!

The user must satisfy himself that the appliance or machine has been returned to its proper state after

carrying out repair work. Technical equipment must not be re-started until all safety devices are in place.

Spare parts must at least correspond to the technical requirements specified by the manufacturer of the

equipment. This will be the case if, for example, original spares are used.

1.7. Liability

Any unlawful alterations to the machine or the software will rule out manufacturer liability for any

resultant damage.

1.8. Interruptions

We recommend installing warning systems to monitor your operating equipment. This will protect your

animals and plants and consequently your economic existence.

In the case of a power failure, the emergency power unit should automatically switch on.

Power units with cardan transmission for attachment to tractors are also suitable for use as emergency

power units. Please consult your property insurance company for More information.

1.9. First Aid

2 Introduction Page 5

2. Introduction

2.1. Equipment description

This air heater is ideal for heating and/or CO2enrichment in greenhouses and plastic tunnels. The

heaters are also excellent for heating poultry sheds or pig sties, or for heating or frost protection in areas

used for the storage and/or preservation of potatoes, tuberous crops and the like.

Particularly in their initial stages of life, young animals need a lot of heat, no matter whether they are

poultry or pigs. Optimum temperatures right from the start have a decisive impact on their development,

health and general performance.

The P 40 - P 120 creates the right conditions for your room. This heater is available for use with

kerosene/paraffin oil or diesel. No chimney is needed. The heater is installed exactly where it will be

most effective in generating heat. 100% of the heat it produces will benefit your animals or plants - so

there is no heat loss. Another positive feature is that the "open combustion" system increases the

relative humidity in the room.

CAUTION

Diesel-fired heaters are not suited for heating and/or CO2enrichment

in greenhouses or plastic tunnels where plants or crops are being

grown.

The P 40 - P 120 is controlled by thermostat or by computer; it also has a photocell control. If for some

reason the appliance does not ignite or the flame is extinguished, the oil supply is immediately cut off.

One solenoid valve unit ensures high levels of safety. No oil can escape unburnt.

2.2. Special safety regulations

The P 40 - P 120 are heaters for use in mentioned rooms. Use of the equipment for

any other purpose shall be regarded as improper use. The manufacturer will not be

liable for any damage resulting from improper use; the user shall bear the sole risk

thereof.

With storing manure, gases are formed which are partly dissolved.

These poisonous and explosive gases (e.g. sulphurhydrogen and methane) can be

released during stirring and rinsing.

With a source of ignition a big explosion may occur.

To prevent a hazardous situation shut off the heaters completely before stirring or

rinsing.

Also observe the following points:

•Close the doors when manure is stored outside.

•Ventilate the room thoroughly.

Notice:

No account is taken with general hazard of fire in this manual. Consult your fire insurance company and/

or your local fire brigade for more information.

*Option, when mounted

The P 40 - P 120 consists of 4 main components:

1. Shell : used for air supply.

2. Combustion chamber : the oil/air mixture is burned in the chamber and ignited by spark ignition.

3. Ventilator : this conveys the hot air into the room, supplies the air needed for

combustion and the air for cooling the combustion chamber and the flue

gases.

4. BCU : the Burner Control Unit; the regulation and safety apparatus.

Description of materials:

Shell and burner chamber : High-grade 430 stainless steel

BCU : PPE (Environment temperature BCU: -10ºC to +60ºC)

The materials used are capable of withstanding the maximum loads.

4 Installation Instructions Page 7

4. Installation Instructions

4.1. Number required

The number of heaters required depends on the size and nature of the room, the required temperature

and the relevant climate zone.

4.2. Installation Instructions

CAUTION

The following points must be observed!

Mounting

The heater must be properly secured using the suspensions eyes or (if it is being fixed down) using

the tunnel brackets on its bottom. Secure the heater using chain or steel cable at least 4 mm in

diameter.

The heater must be as close to the horizontal as possible, and certainly not inclined at an angle of

more than fifteen degrees.

The heater must not be connected to a duct system and no inflammable objects should be placed

within three metres of its outlet.

Oil connection

The oil used as fuel must be purified. (see page 10)

Check the fuel supply lines regularly for leaks and loose fittings.

The oil tank must meet the relevant environmental standards and must be contained within a spillage

sump. The capacity of the sump must be at least the same as the capacity of the tank. The sump

must be protected from the rain.

The bush in the spillage sump through which the primary fuel hose passes must be watertight and oil-

tight by hose clips.

The main fuel pipe must be sturdy and made of stainless material.

The diameter of this pipe must be at least 3/4" (20 mm).

The oil tank and each of the oil boxes must be fitted with a manual oil valve.

The fuel hose must be secured to the heater and to the oil tank with suitable hose clips.

Oil hoses should not be left on the ground, lead them along a steel construction or wall without sharp

bends.

Electrical

Make sure to use a well earthed socket.

Never take off the power when the heater is still working, always let it cool down.

Safety

Never remove the grille or service hatch when the heater is or might start running.

Never use the heater when parts are removed

Keep a free space around the heater, see next page

To avoid oxygen depletion, the room in which the appliances are installed must have enough

ventilation

-either by a mechanical extractor device or ventilation system that extracts at least 10 m3of air per

hour for every 1 kW of installed output,

-or it must have adequate natural ventilation;

If the room has two openings, a ventilation factor of 1.0 (i.e. one change of room air per hour) can be

achieved naturally providing these openings have a free opening area of at least 60 x B cm2where B

is the installed output in kW.

The overall output of the installed appliances must not exceed 1 kW per 20 m3of room volume if

natural ventilation is used.

Always replace defect or faulty parts with original ones or with the same specifications.
