Inspecting the Equipment 
 

ISC air conditioning equipment is designed, manufactured and packed to prevent damage from normal 
handling, shock and vibration during shipment.  It is necessary to inspect your equipment upon receipt 
to insure that there is no visual or hidden damage. 
 
Upon receipt of the equipment, insure that it is always top side up as indicated by “THIS SIDE UP” 
labels.  This insures that the compressor oil is not displaced.   
 

Note:

 If the equipment has been on its side it must be put upright for 

at least 24 hours

 before installing 

or running to insure the compressor oil has returned to the compressor.   
 
All physical damage to packing or signs of damage to the equipment must be noted on the freight bill 
of lading.  Packages must be opened after receipt and inspected for any internal or concealed damage 
to the equipment and to verify proper count and order fulfillment.  Delivery of without the pallet, not top 
side up, other freight on top, damaged or wet should be refused. 

 
Unpacking the Air Conditioner 
 

Always keep air conditioner top up as shown by the packaging label and arrows.  If the unit is to be 
transported after initial unpacking, place air conditioner back in original packing to prevent damage. 
 
For shipment by UPS or freight carrier, repack as received and re-band to the pallet.   
 

Note:

 Shipping without being strapped to the pallet may result in tipping and damage, this will void the 

warranty.
