LOCATION
Use the following guidelines to select a suitable location for these units.
1.Unit is designed for outdoor installation only.
2.Condenser 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.
Excessive exposure of this furnace to contami- nated combustion air may result equipment dam- age or personal injury. Typical contaminates include: permanent wave solutions, chlorinated waxes and cleaners, chlorine based swimming pool chemicals, water softening chemicals, carbon tetrachloride, Halogen type refrigerants, cleaning solvents (e.g. perchloroethylene), printing inks, paint removers, varnishes, hydrochloric acid, cements and glues, antistatic fabric softeners for clothes dryers, masonry acid washing materials.
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 rails. 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.
Length of the forks must be a minimum of 90”.
An adhesive backed label is provided over the out- side of the combustion air inlet opening to prevent moisture from entering the unit which could cause damage to electrical components. Allow this clo- sure label to remain in place until the combustion air hood is to be installed (refer to Figure 7).
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 con- tact 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 largest dimension across the unit, MUST be used across the top of the unit. Refer to Figure 1.
Units may also be moved or lifted with a forklift, from the front or rear only, providing that an accessory skid is used.
