Note: After replacement, the compressor and it’s accessories must have
proper processing, and the components must be recycled according to
the material group (ferrous, non-ferrous, polymers, oils, ...) directives.
These recomendations are intended to minimize the adverse impacts that
may be caused to the environment.
Embraco will not be responsible for, nor will it give a warranty/guarantee
to any compressors proven to be damaged by improper handling,
transportation or storage.

01 Compressor Handling
1 - Introduction
The Embraco compressor is designed for durability as well as
exceptional performance. It is after all, the key component within a
refrigerator, freezer or light commercial refrigeration unit, such as in a
vending machine, water cooler or icemaker.
Despite its steel outer shell, the compressor is not indestructible.
Because of its sensitive internal mechanisms and asymmetric external
components, the compressor requires common sense care in handling.
By following the recommended Handling, Transporting and Storing
Procedures outlined in this valuable brochure, you can be certain the
Embraco compressors you have received will leave your dispatch area in
perfect working condition. You may find these procedures very similar to
the materials handling standards your company already requires.
PLEASE NOTE: Failure to comply with Embraco's recommended
handling procedures can result in irreversible damage, which may
render the compressor unusable and void any warranty. These
procedures include protecting the stored compressors from unfavorable
climatic conditions such as excessive humidity, dust, and most
importantly, precipitation such as rain.

Embraco compressors are shipped according to your company's
instructions. The three most common methods are:
• Bulk - unboxed compressors transported directly on pallets, which
are then stacked according to recommended height and weight.
• Boxed - individually boxed compressors transported on pallets,
which are then stacked according to recommended height and weight.
• Custom format - according to customer specifications.
This brochure will cover the proper handling instructions for Bulk
and Boxed shipments.

2 - Pallet removal
We recommend that pallet removal be conducted from right to left
successively, avoiding contract between the dividers, as shown in figure
below:

Warning: The container's transportation (by water carriage/truckage/
air service) may displace the goods resulting a high risk of tumbling and
fall, while oppening the container's door.

3 – Pallet relocation
Due to product safety and soundness, each palette must be
individually removed and relocated.
OBS: The palette must not be dragged as this operation can
cause breakage or damage to the base structure.
05 Compressor Handling
4 - Pallet lifting
Carefully position the forklift blades under the pallet's main
supports, making certain the lift blades do not come into contact with
the compressors or their external components.
• Positioning the forklift blades under the outer edge of the pallet
frame can cause damage to the compressor's base plate.
Compressor Handling 06
5 - Pallet moving
When transporting loaded pallets, avoid allowing one pallet to come
into contact with
another pallet. These
"knocks" or bumps
can cause damage
to the connectors,
relay cover support,
hermetic terminals
and/or label.
6 - Pallet stacking
Make sure that the point of the fork lift does not exceed the limits of
the palette.
This precaution
will prevent
damage to
compressors on
other palettes.
(Palette
depth = 800 mm
or 31.5” (inches)).
07 Compressor Handling
7 - Truck loading
When loading the pallet(s) of compressors into a truck, take care to
prevent pallets from bumping
into each other. Pallets of
compressors must not
come into contact with
each other while
being transported.
8 - Compressor transporting
When compressors are loaded for delivery in a trailer, the load
must be properly blocked and braced in order to
insure there is no movement
or shifting of the load
during transport, which
could cause damage.
Compressor Handling 08
9 - Additional cargo
Should it become necessary to take on additional freight, the
Carrier must guarantee there will be no contact between other products
and the compressors, especially if these other products are corrosive.
10 - Pallets with compressors packaged
in individual boxes
Regardless of how short the transport distance, the pallets of
compressors in individual boxes must be banded and stretch/shrink
wrapped and protected
from humidity and
rain/or precipitation.
The boxes can
not be transported
in stacked pallets
without being
securely tied, nor
can they be placed
loose on the truck floor.
Precautions must be
taken to prevent denting,
crushing or damaging the boxes.
09 Compressor Handling
11 - Unloading the compressors
Due to their bulk weight and the need to maintain even weight
distribution for safety, standard fork lifts or manual pallet handlers must be
used when unloading the compressors from a truck or stacking area.
12 - Unloading the truck / throwing the boxes
Under no circumstances should any compressor be tossed or
thrown during unloading. The compressor suspension system was
designed to absorb normal transportation requirements, as well as the
vibrations when the compressor is running. However, any other type of
impact, no matter how small, can permanently damage the suspension
system, rendering the compressor unusable and voiding the warranty.
NOTE: Compressor suspension system can be damaged when
boxes are thrown.

13 - Returning compressors to stock
If a surplus of compressors develops at the assembly line, the extra
compressors are usually re-palletized and returned to stock. Please verify
your company's procedures.
During repalletizing movement,
great care should
be taken to position
compressors correctly
on the pallets so they
can stack properly, and
to avoid contact/impact
with the fragile external
compressor components.
14 - Correct positioning for handling, transporting
and storing
The compressor should remain in
an upright position, supported by
its base plate, during handling,
transporting and storing.
This upright position
prevents possible damage
to the compressor's internal
mechanisms, and keeps the oil
out of the suction chamber.

• The table below illustrates other acceptable positions during
these basic operations.
Any position marked “X” should not be used.

This recommendation is applicable for the compressor before or
after it has been installed in the refrigeration system.

15 - Storage/stacking
There should be a minimum distance between stacks of
about 40 cm / 1.30 ft. For personnel safety, and to prevent collapse,
make certain the floor is flat/even and strong enough to accomodate
the accumulated weight of multiple pallets. A pallet, loaded with
compressors, weighs approximately 950 kg / 2,095 lbs.
A four (4) pallet stack is the maximum permitted for safety.

16.1 – Compressor
16.1.1 – Internal Aspects:
The compressor is not subject to any type of internal
degradation, as long as the seals are not violated through
rubber stopper removal.
If not exposed to sunlight, average useful life of the rubber
stoppers is 5 years. During this period they maintain the
characteristics which ensure compressor sealing.
13 Compressor Handling
16.1.2 - External Aspects
Externally, the compressors react according to the
environmental conditions in which they are stored.
The compressors must be transported to and stored in
a covered facility protected on all sides as well as being
protected from aggressive agents such as saline mist,
dampness and dust.
OBS: Dust absorbs and retains humidity, accelerating the
oxidation process.
In non aggressive, covered environments, the compressor is
not expected to present any sign whatsoever of oxidation or
any other external variations for a period of 18 (eighteen)
months.
It is recommended that the compressor be applied before
completing 18 (eighteen) months after date of manufacture.
16.2 - Packaging
16.2.1 - Wooden
Wooden packaging maintains its normal compressor
storage characteristics for 18 (eighteen) months after
manufacturing date of the compressors it contains,
providing that it is kept in a covered place, with side
protection and ventilation.
16.2.2 - Metal bands
Metal bands follow the same behavior patterns as those
described in item 16.1.2 above.
On completing the 18 month storage period, we suggest that
periodic (monthly) verification is conducted to evaluate the soundness of
critical items such as wood, metal bands and the external aspects of the
compressor.
OBS: The compressors and respective packaging which remain for
a certain time in Embraco’s stock, receive a thorough inspection before
being shipped. This ensures that the compressors and packaging are in
perfect condition when released.
