INSTRUCTIONS

GENERAL

1. H-2034 Shrink Tunnel consists of a tunnel and a
conveyor.

The conveyor is a teflon coated mesh belt.
The mesh belt allows the heated air to shrink the
bottom of the package from the tunnel.

2. There are two control panels for the operation of
the machine. The lower panel controls the conveyor
and the upper panel controls the tunnel.

MACHINE STARTUP

1. Turn on the conveyor using the ON/OFF rocker switch.
The ON/OFF switch will light up. Set the conveyor
speed to "2" on the operator panel. (See Figure 1)

4. Set the tunnel temperature to a setting of 325º F
on the tunnel’s operator panel. It will take 20-30
minutes to reach temperature. The heat indicator
light will go off when it has reached temperature.
(See Figure 2)

5. After the initial package has been run through the heat
shrink tunnel, the following adjustments may be made:

a. Increase or decrease the thermostat setting.

b. Increase or decrease the conveyor speed.

2. If the power light is not on, plug in the tunnel.

3. Turn on the tunnel using the ON/OFF switch.

MAINTENANCE

The machine should be inspected on a timely basis to
ensure all is functioning well and in good working order.
There is not much required to keep the machine running
trouble free. The most important area is the seal head.
The following are recommendations for preventative
maintenance on the machine to keep it performing well
over an extended period.

c. Increase or decrease the temperature if

available.

6. Due to the various types of shrinkable films, room
temperatures and voltages, you may have to
experiment with various temperatures and conveyor
speeds, to get the desired shrink. Your film supplier
is familiar with this type of equipment and will be
helpful in determining the best settings for the film
you are using.

MAINTENANCE TIPS

1. Inspect the conveyor belts for wear and
misalignment. If the belts are not tracking properly,
adjust the idler rollers to realign the belts. Replace
worn belts as needed.

2. Lubricate all chain drives every 160 hours of
operation with a bearing grease or chain lubricant.

3. To clean the machine, wipe down the conveyor
belts and other flat surfaces to remove any dirt.
Do not use any type of belt dressing on the
conveyor belts.

MACHINE COMPONENTS

MAIN FRAME ASSEMBLY

1. The main frame assembly of this machine consists of
the rails, conveyor drive motor, and the operator panel.

TUNNEL CONVEYOR ASSEMBLY MESH BELT

1. T

his assembly consists of the tunnel conveyor belt

as

sembly including the DC gear motor. The belt is
heated by a 500W heat element mounted under
the conveyor pan. The heated belt provides positive
shrink on the bottom of the package. The assembly
also includes belt guides and tracking screws.

TUNNEL CONVEYOR ASSEMBLY HEATED BELT

1. This assembly consists of the heated belt including
the DC gear motor. The belt is heated by a 500W
heating element mounted under the conveyor
pan. The heated belt provides positive shrink on the
bottom of the package. The assembly also includes
belt guides and tracking screws.

TUNNEL ASSEMBLY

1. The tunnel assembly set on the tunnel conveyor
uses heated recirculated air to shrink the film onto
the package. The assembly has its own power cord
and requires a dedicated 20Amp circuit. The blower
motor runs in a counterclockwise direction when
looking at the non-shaft end. (See Figure 2)

ELECTRICAL PANEL ASSEMBLY

1. This assembly is located under the drive roller. Only
a qualified technician should access this assembly.

WARNING! Do not tamper with electrical wiring
unless licensed or trained to do so. Disconnect
main power to the machine before attempting
any electrical service.

2. Electrical schematics can be found in the original
manual.

OPERATOR PANEL ASSEMBLY

1. The operator assembly panel consists of the ON/
OFF switch, adjustment for the conveyor speed and
conveyor temperature if available.

2. The ON/OFF switch also acts as a circuit breaker for
the conveyor system. (See Figure 1)

3. The Conveyor Speed is controlled using a DC Drive
Board (203-61) mounted in the Operator Panel. The
speed can vary from 0 feet per minute to 60 feet
per minute.

4. The Conveyor Temperature is controlled using a
variable voltage supply.

CONSOLE LEG KIT (Optional, see below)

1. ULINE item H-2035.

INSTALLATION AND SETUP

IMPORTANT! Prior to machine set up and
installation the general warnings should be
read and fully understood by all personnel
associated with this machinery.

SET-UP INSTRUCTIONS

1. Remove the tunnel from the crate or box.
Inspect for damage.

2. If available, attach the console stand to the tunnel
conveyor rails. See the enclosed instructions for the

stand. Level the machine using the levelers.

3. Place the tunnel on the conveyor with the operator

panels toward the front.

4. Remove any ties used for shipping.

5. Connect machine to power source. Power supply
for the tunnel should be 220 Volt, 10 Amp grounded
power supply. (Have an electrician install a plug on

the power cord, if you are plugging the tunnel into
an electrical outlet.)

CAUTION! Machine should be grounded in
accordance with local electrical codes.

6. Turn on the power to the conveyor using the ON/OFF
switch. Turn on the tunnel using its ON/OFF switch.

7. Ensure the tunnel conveyor is slowly running.
Ensure the tunnel blower is working. Turn the tunnel

temperature to 325º F. When the tunnel has reached
temperature, check the tracking of the tunnel
conveyor’s belt.

8. Test run a few products through the machine to fine
tune the settings in order to achieve as tight a bag
around the product as practical. This will aid in the

shrink process.

9. When finished, turn the tunnel and conveyor
temperatures off. Wait 15-20 minutes and turn off the
tunnel and conveyor.

OPTIONAL LEG KIT INSTALLATION AND SETUP

CAUTION! Assembling the leg kit to the
conveyor can be dangerous. Two people or
a mechanical lift device must be used to
position the conveyor above the leg kit until
they are attached.

SET-UP INSTRUCTIONS

1. Remove the leg kit from the crate. Inspect for
damage.

2. To adjust leg length, remove shipping bolts from legs
(1 bolt per leg). Adjust leg length by measuring the
desired height and subtracting 12" to account for
the conveyor and caster height.

3. Place legs upside down on floor. Position shelf on
legs. Insert socket screws through shelf and each leg
from outside (7 places per leg). Tighten screws with
flat washers, lock washers and nuts. Use a socket
wrench. (See Figure 3)

4. Screw feet into threaded holes provided on bottom
of the shelf. Insert casters into nylon insert next to
feet. (See Figure 4)

The following guidelines are intended to ease the
solution of potential problems that may be encountered
during the everyday operations of the machine.

The cause/solution statements are generally arranged

in order of most probable, easiest solution first on up to
more involved, difficult solutions. If all possible solutions
have been tried, the distributor or factory should be
consulted.

OPERATING ISSUE RECOMMENDATIONS

Conveyor does not power on. Check incoming power. The ON/OFF switch should be lit.

Check power supply line.

Check On/Off switch on the operator panel.

Conveyor powers on but
conveyor does not run.

Conveyor powers on
belt does not heat up.

Check the position of the Conveyor Speed Pot.

Check the voltage to the DC Drive board. The incoming voltage should be equal to the line voltage.

Check the voltage from DC Drive Board. The voltage is DC and will vary with the speed pot setting. If
there isn’t output voltage, replace the board, 203-62.

Check the wiring to the motor. Replace the gear motor.

Check the position of the Conveyor Temp Pot.

Check the voltage to the Voltage Controller. The incoming voltage will vary with the speed pot
setting.

Check heat element for continuity. The 220V element has a resistance of 97 ohms. (Note that the
resistance given is a nominal value.)

Tunnel powers on but does not
heat.

Tunnel conveyor not tracking. Check tension roller on assembly (belt will track to tighter side). Be careful not to over tighten.

Check incoming power. 20-amp service is required.

With power removed check if the thermostat is turning on by checking continuity across wires #1
and #3.

Check the resistance of the heating element. The 220V element has a resistance of 23 ohms.
the resistance value given is a nominal value.)

E

nsure the voltage matches the element voltage.

Check the operation of the blower motor.

Check for air leaks around the blower housing and manifolds.

Check for worn belt.

Check the condition of the belt guides. The belt guides should just touch both sides of the belt.
