Intended use of the product

This product serves exclusively to accelerate the drying curing of putty, filler, base and clear coats. This applies to both water-borne and solvent- based products. It´s site of use is the preparation area and finishing area. Within the automotive industry and vehicle repair sectors, it is used to cure small areas before polishing. The product must not be used for other purposes than the described drying processes. The maximum ambient temperature during operation should not exceed 40°C. The IRT 3-1
PcD and IRT 3-2 PcD dryers must not be used in spray booths or within a distance of 5m from spraying activities in order to avoid explosion risk. This prohibition is also valid for the IRT 3-20 PcD, if not combined with the IRT Dust Cover and Surveillance System (document 714147).
Observe the regulations described in chapter 5.1 in the installation manual (Document 713683), so that spraying is impossible during the drying operation.

Product description

The dryer is an essential aid for paint repair on small and medium sized areas.
The easily maneuverable IRT 3-1 PcD, 3-2 PcD or 3-20 PcD is equipped with one or two compact cassettes.
Each cassette is equipped with three Infra Red (IR) lamps with gold plated freeform reflectors and a ventilator. The design, combined with a gas spring, makes positioning of the cassette simple. The IR lamps are easily exchangeable and the reflectors are
protected against mechanical damage by a mesh.
The dryer has a selection of sophisticated programs.

2.1 Particular advantages
2.1.1 Higher quality
Using the dryer when you cure putty also improves the quality of the top coat.
The shortwave IR curing enables the coating to be cured from the inside outwards. This prevents solvents to be trapped inside the coating and ensures a fast and high quality curing.

2.1.2 Short drying times
60 cm distance

2.1.3 Hi-tech shape of reflectors with short wave IR
By using short-wave technology and gold-coated reflectors with a high tech shape important advantages are achieved.
Firstly, by radiating only the needed areas and not heating any air, a lower energy consumption is achieved.
Secondly, a more uniform surface temperature is obtained by distributing the energy evenly.
Thirdly, a larger drying surface is achieved.
Fourthly, less radiation outside the curing area.

2.2 Technical data
All dryers emit short wave IR-radiation with a peak at 1120 nm. The following figures show the maximum drying area, when the respective dryer is used in 60 cm distance from a black sheet metal.

Instructions to the owner

The owner of the dryer must produce clear operating instructions, adapted to local site conditions, and make these available to all users who have to observe these operating instructions.
This appliance is not intended for use by persons (including children) with reduced  physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety.
Children should be supervised to ensure that they do not play with the appliance. Dispose of used items at the nearest environmental protection facility for recycling.
For safety reasons the infrared dryer must be supplied by recommended maximum fuse, see tables in chapter 2.2.

Safety instructions

The mobile dryer must not be exposed to paint fog, sanding dust or solvents, due to fire risk. Furthermore, this will reduce the lifetime of the dryer. Allow for sufficient cooling time of the dryer. The distance to the object to be dried must be sufficient. Otherwise there is risk for fire or explosion! Keep all flammable materials in a sufficient distance from the hot surfaces of the dryer.

4.1 Hazards
Tilting
The risk for tilting increases when the arm is located in an upright position. Turning both cassettes to one side also increases the risk for tilting.

Fire and explosion
Do not store, prepare or use solvent-containing materials within a 5 m/16 feet radius of the mobile dryer. Flammable materials should not be placed close to a drying device in use.
If you have a distance less than 60 cm/2 feet to the object the temperature might raise quickly and the risk for fire increases. Never direct the cassette towards highly combustible materials.

Electrical equipment
The mobile dryer is operated with high electrical voltage, which can be highly dangerous.
Before accessing live parts, remove the main connector from the wall socket. Only professional electricians may have direct access to the electrical components.
If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid a hazard.

WARNING!
Intensive heat radiation. Hands, face and other parts of the body should be exposed as little as possible to the heat radiation.

This test procedure is only available in English. By pressing the yes button you enter the first step of the self test.

To exit the self test, press the start/stop button. Automatic testing includes the  following:

Test 1: Push Button Test
All buttons on the control unit are tested. The corresponding symbols are displayed by pressing the buttons.

Press enter for approx.  three seconds inorder to continue to the  next step of the test program.
Test 2: Display Test
Verify that all pixels light up on the display. Press enter  and check that all pixels go out. Press enter to continue.

• or upper left software button

Test 3: Buzzer Test

Maintenance and service

Weekly
Check that all IR lamps light up during mobile dryer operation. Defect IR lamps can cause uneven heat distribution over the surface.
Clean the dryer from dust, which can be a cause of fire, with a damp cloth.
Check that all cables are undamaged. A damaged cable can be a danger to life!

Monthly
Check the gold coated reflectors. Damaged or extremely  dirty reflectors can over heat the reflector body and/ or the cassette. In case of doubt, please contact the customer service in order to clarify if the gold coated reflector needs to be changed.

Yearly
Plan to change the air filter approx. once per year. You  will get a message in the software when it is time to change. When starting up the dryer you will get an indication on how much of the filter time that is used.

9.1 Filter replacement
Attention!
The filters are disposable and should not be reused.

1. Use a knife or screw driver to bend loose the two plastic plugs at the cassette side plates.
2. Remove the used filter.
3. Insert the new filter so the IRT logo is visible from the outside.
4. Place the long side of the filter opposite to the two plug holes on the cassette according to picture.
5. Push in the filter until the two plugs can be reattached.
6. Reset the filter timer. Log into advanced settings mode according to chapter 8.1 and 8.2. Move to parameter 45 and press yes for reset the filter.

9.2 IRT lamp replacement
Attention!
Do not touch either the gold coated reflector or the new IR lamp with your fingers. Only remove the protective paper on the IR lamp after you have installed it.

1. Disconnect power supply.
2. Loosen the three top screws on the front plate of the cassette.
3. Disconnect the cable connector.
4. Loosen the four screws at the ends of the reflector and remove the reflector from the plate.
5. Remove the mesh and unscrew the lamp from the two ends.
6. Install new lamps in the reverse order.

9.3 Gas pressure spring replacement
If the mobile dryer does not park in highest or lowest position but falls or raises slightly by itself, tighten the 4 bolts indicated with the letter “C” in fig 2.
If the dryer arm still does not park or becomes heavy to adjust, the gas pressure spring must be replaced.

Attention!
Due to high weight and complexity it is recommended to be two persons or one person with a lifting device when performing this service.

1. Remove the four screws fastening the cover that is located on either side of the arm (fig 1).

2. Place the parallel arm in the farmost upright position (fig 2).

3. Before removing the pins holding the gas spring, as much pressure as possible from the gas spring should be relieved. To do this, raise the arm slightly until the pins are loose.
   Attention!
   At all times when the gas spring is not securely in position with pins and locking rings, the arm can fall down heavily from it´s upright position and create great danger.

4. Remove the locking rings and the two pins. Move the gas spring slightly upwards/forward and then remove it (fig 2).

5. Place the new gas spring in the same direction as the old one. Reassemble in the reversed order.

Attention! Ensure that the locking rings are refastened properly.
