Check Compressor Mounting

UNITS 48/50MP62L Ð Compressors are mounted on pans and are held down by 4 rail bolts during shipment. After unit is installed, loosen each of these bolts until the snubber washer can be moved with ®nger pressure. See Fig. 40 and 41.

UNITS 48/50MP70M-10R Ð Compressors are mounted on rails and held down by rail bolts during shipment. After unit is installed, loosen the rail bolts to allow the rails and com- pressors to ¯oat freely on the springs located under the rails. See Fig. 40, 42, and 43.

Install Accessories Ð For applications requiring special accessories, the following packages are available: con- denser coil hail guard package, condenser coil protective grilles, and compressor security grilles. Refer to the acces- sory installation instructions for information on accessory installation.

Fan Isolator Adjustment Ð Remove shipping hard- ware from both the supply fan and the optional exhaust fan. The indoor fan shipping blocks on both the supply fan and the optional power exhaust fan (4 per fan) must be removed from each corner of the fan sled before starting unit. Re- move shipping bolt connecting bottom ¯anges of the fan sled crossrail with the fan support rail. Remove the wooden ship- ping block from each corner. See Fig. 39.

After removing all shipping blocks, level fan sled using the adjusting screws of the spring isolators. Verify dimen- sions from fan support rail to fan sled cross rail of 7-in. on all 4 corners.
