Introducon:

The Mercury Compact Infrared Dryer is an economical and ideal dryer for any home based business or shop with a limited amount

of space or budget. Using a large IR heang panel and an adjustable belt speed, the Compact Dryer gives you the capability of

professional, long lasng prints. The Compact Dryer comes with a 20” wide belt capable of handling 72 pieces per hour. With

adjustable heat gates the Compact can handle just about any job.

Standard Operaons Guide:

Once the Mercury Compact Dryer is installed, it’s me to cure! The belt speed is crical to ensure the quality of the print and to

prevent the garments from burning. The surface of the IR element can reach temperatures of 600°f, with a curing temperature of

325°-350°f. The belt speed adjustment will allow most garments to pass safely thru the dryer. The heat gates allows the user to

control how much heat is contained or expelled from the dryer.

FAQ.

1. My dryer turns on but the belt isn't spinning.

Does the belt turn easily by hand? If yes, loosen the belt. (Image 1) Next, using pliers pull the belt pin to separate the two ends of

the belt (Image 2 and 3)

Image 1

Next unplug the belt drive motor (Image 4). Remove the motor and roller assembly and set it on a at surface (Image 5). With the

assembly now removed, inspect the chain and sprockets. If the chain has come o it will need to be put back on, however, there is

a reason it has come o. Inspect the sprockets for damage or missing teeth, the sprocket should look like the sprocket in Image 6.

If sprocket is good, next check sprocket alignment (Image 7). If sprockets are misaligned check the set screws on the bearings that

secure the roller sha (Image 9).

If the bearings are loose on the motor side, reset the distance between the arms and the belt

tension bracket (Image 8). This will allow for the assembly to t properly into the arms. Secure

the bearing set screws (Image 9). If the bearings are ght, manually align the chain. Loosen the

set screws for the sprocket, take a measurement from the inside of the bracket to the chain.

Both drive and roller sprocket should be the same (Image 10).

2. The chain is on, but my belt sll won’t turn.

Using a digital Volt/Ohm meter in the VDC seng (Image 11), check the voltage going to the belt motor. The motor operates on a

0v - 90v DC scale. Depending on where the speed control is set will determine the voltage reading. Unplug the belt motor, the side

of the plug with the white/black wires is the power side (Image 4). Insert the meter’s probes into the plug as show in image 12.

With the probes inserted take note of the reading on the meter, if it displays a negave reading, swap the probes and take another

reading.

With the probes inserted into the plug, set the belt speed control at 0, the meter should read zero or close to it. Then turn the

belt speed to 100, the meter should now read 90vdc. If the reading is 0 regardless of speed control seng its now me to open

the top of the dryer. There are 4 screws on the top and 2 on either side just above the vent doors, li o the top of the dryer and

set it to the side (Image 13 and 14)

Image 13 Image 14

Once the top is removed, the speed control board is now visible. (Image 15)

Locate the ceramic resistor on the speed control board (Image 16)

Image 16

Once the Resistor is located, remove it. Using a piece of wire or paper clip, jump the two open terminals the resistor came out

of (Image 17) Image 17

Using the Digital meter in the VDC seng, repeat the tesng seen in images 11 and 12. Start at 0 and move the belt speed control

to 100, if the full range of voltage ( 0 - 90vdc) is reached, the resistor will need to be replaced. If no change is seen in the voltage

and the belt sll wont turn, either the speed control board or motor will need to be replaced.

Part AJ

Resistor

To test the Speed Control Board, use a digital Volt/Ohm meter set the dial to the ACV seng (ACV 200-1000 on a non auto-ranging

meter). With the Red probe from the meter, touch the circuit tab on L1, with the black probe touch the L2 (Image 18)

Image 18

Image 19

If the AC voltage coming into the board is correct (115/230 ACV) but there is no power coming out, the speed control board

will need to be replaced.

3. My Dryer Isn't Heang up

Remove the top of the dryer (Image 13 and 14). Locate the Power Switch (Image 20)

Image 20

Once the Switch is located, 2 large WHITE wires can be seen connected to the switch (Image 20). Using a digital Volt/Ohm meter

set the dial to the ACV seng (ACV 200-1000 on a non auto-ranging meter) , turn the dryer on and test the voltage across the

switch. The Dryer uses 115v or 230v, to verify check the voltage rang on the fan (Image 22).

Image 22 Image 22.1

Fan 220V

Part V

Fan 115V Part AU

If voltage reading is normal, the element is bad (Image 23). To verify the element is bad use a digital Volt/Ohm meter in the

resistance seng (Omega symbol Ω). With the dryer OFF, locate the terminal block. Check the 2 large WHITE wires leading to

the element . For connuity, the meter should have a low reading or produce a beep, if the meter reads zero or doesn’t produce a

beep, the element will need to be replaced.
