Installation

511.06-N3Y

LIMITATIONS

These units must be installed in accordance with the following national and local safety codes:

In U.S.A.:

1.National Electrical Code ANSI/NFPA No. 70.

2.Local electric utility requirements.

In Canada:

1.Current Canadian Electrical Code CSA C22.1.

2.Local electrical codes.

Refer to the Unit Application Data and to thefor Electric Heat Application Data table.

If components are to be added to a unit to meet local codes, they are to be installed at the dealer’s and/or the customer’s expense.

Size of unit for proposed installation should be based on heat loss/heat gain calculation made according to the methods of the Air Conditioning Contractors of America (ACCA).

FIG. 1 - TYPICAL RIGGING

Units may also be moved or lifted with a forklift, from the front or rear only, providing that an accessory skid is used.

LENGTH OF FORKS MUST BE A MINIMUM OF 90".

Refer to the Physical Data tablefor unit weights and to the figure below for approximate center of gravity.

COIL END

LOCATION

Use the following guidelines to select a suitable location for these units.

1.Unit is designed for outdoor installation only.

2.Outdoor coils must have an unlimited supply of air. Where a choice of location is possible, position the unit on either north or east side of building.

3.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 rail dimensions. Do not tie slab to the building foundation.

4.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.

CAUTION: 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.

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

RIGGING AND HANDLING

Exercise care when moving the unit. Do not remove any packaging until the unit is near the place of installation. Rig the unit by attaching chain or cable slings to the round lifting holes provided in the base rails. Spreaders, whose length exceeds the larger dimension across the unit, MUST be used across the top of the unit. Refer to the Typical Rigging Figure.

FIG. 2 - CENTER OF GRAVITY

CLEARANCES

All units require certain clearances for proper operation and service. Refer to the Dimensions and Clearances Figure for the clearances required for combustible construction, servicing, and proper unit operation.

WARNING: Do not permit overhanging structures or shrubs to obstruct outdoor air discharge outlet.

DUCTWORK

Ductwork should be designed and sized according to the methods in Manual Q of the Air Conditioning Contractors of America (ACCA).

A closed return duct system shall be used. This shall not preclude use of economizers or outdoor fresh air intake. The supply and return air duct connections at the unit should be made with flexible joints to minimize transmission of noise.

The supply and return air duct systems should be designed for the CFM and static requirements of the job. They should NOT be sized to match the dimensions of the duct connections on the unit.

CAUTION: When fastening ductwork to side duct flanges on the unit, insert screws through duct flanges only. DO NOT insert screws through casing.

Outdoor ductwork must be insulated and waterproofed.

Refer to the Dimensions and Clearances Figure for information concerning side and bottom supply and return air duct openings.
