LOCATION

Use the following guidelines to select a suitable loca- tion for these units.

1.Unit is designed for outdoor installation only.

2.Condenser coils must have an unlimited supply of air.

3.Where a choice of location is possible, position the unit on either north or east side of building.

4.For ground level installation, use a level concrete slab with a minimum thickness of 4 inches. The length and width should be at least 6 inches greater than the unit base rails. Do not tie slab to the building foundation.

5.Roof structures must be able to support the weight of the unit and its options and/or accessories. Unit must be installed on a solid level roof curb or appropriate angle iron frame.

6.Maintain level tolerance to 1/2 inch maximum across the entire length or width of the unit.

If a unit is to be installed on a roof curb or special frame other than a YORK roof curb, gasketing must be applied to all surfaces that come in contact with the unit underside.

RIGGING AND HANDLING

Exercise care when moving the unit. Do not remove any packaging until the unit is near the place of installa- tion. Rig the unit by attaching chain or cable slings to the lifting holes provided in the base rails. Spreader bars, whose length exceeds the largest dimension across the unit, MUST BE USED.

Units may also be moved or lifted with a forklift. Slotted openings in the base rails are provided for this pur- pose. Fork lengths must be a minimum of 42 inches.

Remove the nesting brackets from the four corners on the top of the unit. All screws that are removed when removing the brackets must be replaced on the unit.

Refer to Table 8 for unit weights and to the Figure 6 for approximate center of gravity.

Before lifting a unit, make sure that all panels are in place and that its weight is distributed equally on all cables so it will lift evenly.

CLEARANCES

All units require certain clearances for proper operation and service. Installer must make provisions for ade- quate ventilation air. Refer to Dimensions and Clear- ances shown in Figures 7 through 10 and Table 14 for the clearances required for combustible construction, servicing, and proper unit operation.

Do not permit overhanging structures or shrubs to obstruct outdoor air discharge outlet, com- bustion air inlet or vent outlets.
