IMPORTANT - PLEASE READ THIS CAREFULLY

The development of a good safety program, that is rigidly
enforced, is absolutely imperative when involved in the operation of
industrial equipment. Our machinery is well designed and includes
extremely important safety features. The part you the user play
through proper installation and maintenance procedures is of far
greater significance than our designs. Only properly trained
individuals following rigidly enforced safety rules, as recommended
by A.N.S.I. and O.S.H.A., should be allowed to operate these
machines.

UNPACKING

THOROUGHLY INSPECT EQUIPMENT UPON ARRIVAL.

If goods are received short or in a damaged condition, it is

important that you notify the carrier’s driver before he leaves your
company and insist on a notation of the loss or damage across the

face of the freight bill. Unless this is done, no claim can be enforced
against the transportation company.

If concealed loss or damage is discovered, notify the carrier at
once and insist on an inspection. This is absolutely necessary! A
concealed damage report must be made no later than ten (10) days
from the date the shipment was delivered. Unless you do this, the

carrier will not consider any claim for loss or damage. The carrier’s

agent will then make an inspection and grant a concealed damage
notation. If you give the transportation company a clear receipt for
the goods that have been damaged or lost in transit, you do so at
your own risk and expense.

All claims must be filed within six 30 days of delivery date or
carrier will not accept them.

Sealer Sales, Inc. is willing to assist in every possible manner to
collect claims for loss or damage; however, this does not hold Sealer
Sales, Inc. responsible for collection on claims or replacement
of material.

Do not throw away damaged pallets or box until
freight inspection has occurred.

INSTALLATION AND BASIC SET-UP

IMPORTANT

Read this manual carefully, and make it available to everyone
connected with the supervision, maintenance, or production of this
machine. Additional copies are available at your request. (Contact
your distributor for this information.) Be very careful when
operating, adjusting, or servicing this equipment. If in doubt, stop
and obtain qualified help before proceeding.

INSTALLATION OF SHRINK TUNNEL

Place the tunnel in the desired location with the required
electrical power source available. (See power requirements.) Make
certain that proper electrical wiring is provided to guard against low
voltage. If the voltage is too low, the equipment will not function
properly.

Finding the proper location is a most important function of the
initial set-up. One must take several factors into consideration:

1. Adequate power source.

2. Relationship to source of product.

3. Relationship to sealer.

4. Relationship to any conveyors necessary to remove
finished product.

5. Convenience of operator.

6. Avoid drafty areas as heat may be unintentionally
drawn from the tunnel and reduce its efficiency.

An electrician should install a plug on the end of the main
power cord. If there is any doubt, get qualified assistance to do the
initial installation. Do not take any chances!
