II. Incoming Inspection

Kooltronic Air Conditioners are designed, built and packaged to withstand the shock and vibration normally
associated with shipment by common carriers. Occasionally improper handling during shipping causes damage.
Such handling could include unbanding of palletized shipments, failing to respect 

"This Side Up"

arrows, rough

handling, falling off conveyors, excessive vibration, crushing, etc. Therefore, a thorough inspection should be done
upon receipt of all shipments. Any carton tears, dents, scratches, loose articles or evidence of oil are signs of
damage and should be noted on the Freight Bill. Cartons should be opened promptly and the units inspected for
CONCEALED DAMAGE. Kooltronic Air Conditioners must be delivered in the proper mounting position to assure
that damage to the compressor has not occurred during shipping. Any Kooltronic Air Conditioner that is delivered
removed from the banded pallet, lying down or double stacked should be refused.

An immediate claim MUST be filed with the freight carrier and an inspection requested. Retain all packing
materials. Kooltronic cannot assume responsibility for Consignee's failure to file a timely freight claim.

III. Product Handling:

1) Do not attempt to operate your Kooltronic Air Conditioner until you read and thoroughly understand this

Manual. See section

VI PRE-INSTALLATION TESTING.

2) Before operating the Kooltronic Air Conditioner be certain that it is placed in its correct mounting position.

This Air Conditioner is designed to operate in a vertical position only. 

This placement must be done a

minimum of 5 minutes prior to operating in order to allow the compressor oil to drain to the compressor sump
area.

CAUTION

3) Before operating this unit, all electrical wiring must be checked to assure the proper connection to the

correct power source. Minimum circuit ampacity should be at least 125% of the amperage found on the
nameplate for the corresponding voltage. Do not exceed the maximum fuse size found on the nameplate.

4) We do not recommend that Air Conditioners be shipped to their final destination attached to an enclosure.

In the event that the Air Conditioner needs to be shipped attached to an enclosure it is strongly
recommended that proper support be provided for the Air Conditioner. Excessive vibration can occur if Air
Conditioners are not properly supported when shipped on enclosures, increasing the potential for internal
damage and voiding the warranty.

5)

PROCEDURE FOR PROPER PACKING AND SHIPMENT OF KOOLTRONIC AIR
CONDITIONERS:

Keep Air Conditioner in proper upright position indicated by arrow markers.

Pack Air Conditioner in an appropriate carton (preferably original carton if possible), with adequate
internal protective packaging, making sure carton is marked and is kept in correct upright position.

For local, controlled transportation, strap carton to a secure part of truck to prevent falling or
sliding, minimize vibration, etc.

For common carrier shipment, band unit(s) securely to a pallet. Unpalleted shipment risks
severe damage which voids the warranty.

Kooltronic Air Conditioners must be operated in their proper mounting position. If attempts are

made to operate a unit that is not in its designed mounting position, permanent compressor

damage will occur. This action will void the warranty. To avoid compressor damage do not tip the

unit more than 45° from its proper mounting position.
