3. INSTALLATION
Page 3
The shortwave infrared curing lamp is divided into 3 parts (a base, a column and a cassette).
1) Installation of the base.
a. Open the packing of the base.
b. Install the four wheels on the base respectively and tighten up the screws. Usually, the
wheels with brakes should be mounted on the rear of the base.
2) Installation of the column.
a. Open the packing of the column.
b. Put the column vertically on the top of the base, directly engage the screw holes and
tighten up using the screws.
c. Connect the support arm with the column for supporting cassette.
d. Connect the lifter with the column to control the up and down movement of cassette.
3) Installation of the cassette.
a. Open the packing of the cassette.
b. Connect cassette with support arm and tighten up with the screws.
c. Connect control wires and adjust the angle of cassette.

1. Setting for Distance
Press and hold the "Setting" (Button 5) to enter into setting mode. Set the curing parameters
according to the requirements of different paints. Nearest distance: The equipment will stop
automatically when the distance between the panel and emitter is less than its preset distance.
Farthest distance: The equipment will stop automatically when the distance between the panel
and emitter exceed its preset distance. The equipment works only in the preset distance range.
2. Setting for Temperature
Press "Power adjustment" (Button 3) when the lamp is ready to use to set the temperature.
3. Setting for Automatic Mode
Press "Setting" (Button 5) when the lamp is ready to use to set curing parameters (shown on
LCD display) according to the requirements of different paints to achieve the best effect - see
next page.

d. Press the "Auto" button and then press "Start" to go into the automatic curing mode.
Once the automatic mode is selected, four related cure programs become available to
the user – Program 1-4 (Fig. A). The data of these four programs, time (min) and power
(%), can be set respectively (Fig. B). (The curing time and power should be set according
to the requirements of the paint material).
e. Setting curing time. Press the navigation buttons "time +" or "time -” (Button 4, Page 4)
when the lamp is ready to use to adjust curing time.
f. Protect the lamp against shocks and vibrations when the lamp is in use.
g. After this program is completed, the system is able to carry out other programs. Make
sure to turn off the system when the equipment is not in use and keep the equipment

2.The data can also be adjusted during program
with a long press on the button “Setting”
changing the interface to set the data.
c. Move the cassette forward or backward from the paint surface to adjust to the best
distance for curing. The distance data will be detected and shown on the display screen
automatically. The measuring range is 20-120cm and beyond it is blind zone. The curing
distance between the cassette and paint surface should be set according to the paint
material and weather conditions (air humidity). Usually, keeping a distance of about
45cm from the paint surface is recommended.
