1. Introduction
Desert Aire climate control units are designed to provide years of reliable service when installed
properly. Read these instructions carefully before you install the unit.
1.1. Inspection
Desert Aire inspects and tests each climate control unit before it leaves the factory so that you
receive a quality piece of equipment. Unfortunately, equipment may become damaged in
transit. Inspect the unit carefully before signing the receiving papers. Check for both visible and
concealed damage. Remove crating and inspect the exterior cabinet for damage. Dented
panels, broken crating or any uid leaking from the unit should be documented upon delivery.
1.2. Freight Damage Claims
Freight is shipped FOB, if damage is noted, the BOL must be marked damaged to process a
claim - Failure to do so will void any future claims
If the unit has been damaged, document the extent of the damage. Take pictures if possible.
Next, obtain a claim form from the carrier. Promptly ll out and return the form. Carriers may
deny claims that you have not lled out within a week of delivery. Notify Desert Aire of any
damage. Damaged units must have signed documents at the time of delivery to be eligible
for a freight claim.
1.3. Rigging
1. Failure to observe rigging instructions may lead to equipment damage, personal
injury, or death.
2. Lifting method and procedure must comply with all local and national codes and
regulations.
3. The use of safety slings in addition to lifting lugs is required.
4. Do not lift the dehumidifier in high winds or above people.
Desert Aire equipment is solidly built and can be very heavy. Avoid personal injury and damaging
the equipment by planning the installation carefully. Use moving equipment whenever possible.
1.3.1. Rigging the Unit
Depending upon the unit type, various rigging methods are used to best lift the
equipment. Please reference the applicable sections below:

Personnel should avoid stepping on the top of the unit. Desert Aire
air handlers are not designed to support the weight of a person on all
portions of the roof. Damage incurred through caved or distorted top
panels will not be covered under warranty. If you must walk on the top
panels, carefully walk on the edges where structural integrity is
greatest.
