2. Structure Characteristics and Working Principle

2.1 Main Functions

For cabinet dryer, materials to be dried are placed on the stainless steel made
moveable material trays. During operation, process air will flow to heating wire
and be heated up to required temperature, then flow through a manifold with
evenly scattered holes. Moisture air is sent out through air exhaust port. It is
designed to achieve an even drying effect.

3. Installation and Debugging

Install the CD Cabinet Dryer at a proper place where is easy for service and
maintenance.

3.1 Attentions During Installation

1) Make sure voltage and frequency of the power source comply with those
indicated on the manufacture's plate, which is attached to the machine.

2) Power cable and earth connections should conform with local regulations.

3) Use independent power cable and ON/OFF switch. The cable's size
should not smaller than those applied in the control box.

4) The power cable connection terminals should be tightened securely.

5) The machine requires a 3-phase 4-wire power source, connect the power
lead (L1, L2, L3) to the live wires, and the earth (PE) to the ground.

6) Power supply requirements:

Main power voltage: ±5%
Main power frequency: ±2%

7) Please refer to electrical drawing of each model to get the detailed power
supply specifications

3.2 Machine Ins Tallation Distance

Picture 3-1: Machine Ins Tallation Distance

Note: Keep the machine 2M from the combustible distance.

13(21)

3.3 Check the Rotation Direction of Blower

1) Check whether the wind direction of inlet and outlet on the two sides of oven is
right.

2) If the rotation direction is not right:

a. Stop the machine.
b. Turn off the main switch.
c. Change any two lines of the main power supply 's three lines.
d. Stop the machine, and check it again.

14(21)

4. Application and Operation

Open the distribution box and connect the power source in accordance with wiring
diagram. Make sure that the power voltage is in compliance with the required
specifications.

Notes: Before connecting, the main switch and heat switch

should be off.

4.1 Test

After all wires are connected, turn the main switch and the heater switch to “ON”,
then the pilot lamp light, observe if the rotating direction of blower is consistent
with the arrow. If not, exchange any two power cables.

4.2 Setting Temperature

Firstly press key , then press keys to adjust temperature , finally press
confirmative key to confirm the adjusting. Use temperature adjustor together
with material dry thermometer to set the temperature. After heating for a period of
time, the yellow light and red light will flash alternatively, which indicates that the
setting temperature value has been reached, at that time the actual temperature
of temperature controller and setting temperature are the same.

4.3 Adjustment of Air Rate

Adjustment of air rate is the most important factor for the drying result, should
adjust the air outlet and inlet when drying different material.
For example:

1) When heat and brake the electronic, galvanized and baked-finish products,
the air-inlet and air-outlet should be closed completely.

2) When dry up the plastic materials and other products contained much
moisture, the air-inlet and air-outlet should be opened properly.

Picture 4-2: Adjustment of Air Rate

4.4 Start-up Timer Setting

Turn on timer switch after all switch has been on, take down the glassy shield
outside of the timer, then push the small black switch to "Auto". Set current time
and drying time required, cover the glassy shield. Therefore the cabinet dryer will
run automatically till drying time.
