__________________________________________________________________________________________
Section I. SERVICE UPON RECEIPT OF EQUIPMENT
2-1. Unloading Equipment
a.
The air conditioner is shipped in a single wood crate, packaged for shipment in conformance with Military
Specifications PPP-B-636 and PPP-B-601.
b.
Lift the packaged air conditioner from the carrier using a hoisting device with a minimum rating of 750 pounds
capacity.
Caution:
When unloading the unit be careful to avoid damage to the air conditioner and separately packaged
components. Make sure the air conditioner maintains an upright position during unloading.
2-2. Unpacking Equipment
The air conditioner is securely fastened to supports and bolted to a wooden skid within the crate as shown in figure 2-1.
Unpack equipment as follows:
a.
Cut the metal straps, and uncrate the air conditioner.
b.
Carefully remove the barrier paper and tape.
c.
Remove the eight bolts securing the air conditioner to the wood skid. Using one of the following two methods,
remove the air conditioner from the skid.
(1)
Using the four lifting eyes in the top corners of the cabinet(fig. 1-10) lift the air conditioner with a sling.
Use spreader bars to maintain a 90-degree angle between the sling and cabinet top panel while lifting air conditioner off
skid.
Caution:
Guy ropes must be used to prevent excessive swinging that might damage the air conditioner when a
hoisting device is used.
(2) Using a fork lift with suitable fork prong dimensions, insert fork lift prongs into fork lift channels formed by the
base of the airconditioner (fig. 1-10). Elevate slightly and check stability of unit; the lift air conditioner off skid.
d. Open the separate shipping carton and unpack the remote control box and wiring harness assemblies.
Note
Tiedown points, located at each of the four ends of the fork lift channels, facilitate moving the
airconditioner after its been uncrated. When using the diedown points place a pipe bushing at the four
points between the holes in the ends of the fork lift channels (fig. 1-10); then attach an eyebolt and clevis
through the bushings to provide for attaching the tiedown straps to the airconditioner.
2-3. Inspecting and Servicing Equipment
a.
A complete inspection of the air conditioner should be made upon receipt of unit. Inspect the air conditioner as
follows:
(1)
Remove the housing panels (para. 3-23 thru 3-29), and open the condenser discharge door (para. 3-30).
