Exhaust Requirements MD8 Series Dryers
MD 8 Series dryers are produced under the UL Code 795, Fourth Addition –
Commercial Industrial Gas Heating Equipment. The dryer is also listed under ETL
compliance with the same and has a reference number of J98*10442. All utility hook
ups and exhaust connections should comply with these codes.
The MD8 is supplied with a 6 inch exhaust duct connection point. Connect 6 inch single
wall or double wall ventilation piping. Please consult your local city and/or state code to
determine which type of ventilation piping is required.
If the ventilation piping travels a distance of over 30 feet from the initial connection
point or if there are more than two 90 degree bends in the total run on the ventilation
piping, a booster blower may be required. It is necessary to maintain 350 - 500
CFM Maximum Exhaust Capacity (12 -17 M3 / Minute Maximum) at connection
point. Exhausting air temperature after 15 ft is approximately 200F. (95C)

OPERATIONS INSTRUCTIONS
MD8 INTERCHANGE EQUIPMENT, INC.
1. Blower on—Push Button
2. Blower off—Push and Hold Button for 3 seconds
START DRYER:
Blower must be on—
Turn burner switch to right and hold until blue purge light illuminates.
Set temperature on controller by using the up and down arrows. (start at 350 degree).
Set belt speed to the desired dwell time. This is dependent upon many factors; ink type
material type/color and product type. Consult your ink supplier to determine exact ink
requirements.
To turn off - turn burner switch to left. This will turn off heat (gas or electric). Blower will
time out (remain on) for 10 minutes and then shut down. The belt will continue to run as
long as power is supplied to dryer. After blower has timed out, power may now be
disconnected from dryer.
Operating Instruction

BELT TRACKING
MD8INTERCHANGE EQUIPMENT, INC.
1. If your MD8 is equipped with the "Belt Sensor" tracking system, supply the system
with 70-80 psi of compressed air. Belt tracking is very important, and all tracking
systems must be monitored especially during the break-in period.
2. Check that the tracking arm is centered between the two jacking bolts. Bolts should
only be hand tight (see Figure c).
3. Center Belt on infeed and exit roll. Adjust belt proximity switch to read edge of belt,
then move back ¼".
4. Remove slack from belt using adjustment bolts until belt has a uniform tension.
(Too much tension can cause belt failure, do not over tighten.)
5. Turn conveyor switch to on position. Turn speed to a minimum. Belt sensor switch
must not be reading the belt. When the switch does not read the belt, the tracking
cylinder is extended causing the belt to walk towards the belt sensor switch. The belt
should always walk towards the switch.
6. Slowly increase speed to determine which way the belt is walking. If belt is walking
away from proximity switch, loosen jacking bolt A; this will further extend the tracking
cylinder causing the belt to walk towards the proximity switch.
7. When the switch reads edge of belt for a constant 2 seconds, the cylinder will retract
which will cause the belt to walk away from the switch. If this does not happen,
loosen jacking bolt B; this will allow the cylinder to further retract.
8. Adjust the position of the switch (by rotating rod in or out) to control how the belt
centers on the main rollers.
9. When adjusted correctly, belt movement is very slow and steady. If belt moves left
and right too rapidly, adjust jacking bolts A&B to slow movement down.

MD-8 GAS FIRED MODEL MAINTENANCE
1. Grease the bearings on the blower fan drive shaft (with high
temperature grease only),every 200 operating hours or once a month
depending on your production level. They are located on either side of the
burner section under the heat extensions.
2. Grease the shaft and conveyor bearings (with standard grease) every
200 operating hours or once a month depending on your production level.
Check oil level in belt speed reducer every 4 to 5 months or every 300
operating hours.
3. Check belt drive brushes every 600 operating hours.
4. If the dryer is equipped with "Belt Sensor" switch, check the operation of
cylinder for smooth operation. This is important to keep the belt tracking
working properly.
5. The dryer is equipped with lint filters which are located on the rear of the
dryer for easy access. They should be cleaned at least once a week along with
recirculation blower blades.
(depending on your production level). Check daily until a schedule can be
determined.
6. We recommend checking the inside of the dryer for buildup of dust and
debris. This can easily be accomplished by un-latching the exhaust hoods
and checking the inside of the hoods. The burner section can be checked
by opening the door located under the filters. Every application is different,
so there is no set schedule. Check monthly until a schedule can be
determine.
7. Inspect Blower Motor Pulley Belt damage. Tension if necessary.
8. Inspect and clean Flamerods and Igniter at Burner Basket location with a fine
grit sandpaper quarterly. Also inspect and replace if necessary, all related
wiring.
9. Inspect and clean or replace Main Panel Cooling Fan Filter periodically
NOTE:
It is very important to keep the entire dryer clean. If lint is allowed to
build up, the
efficiency and drying capabilities will be greatly diminished.
