Installation
To ensure warranty coverage, this equipment must be commissioned and serviced by an authorized
YORK service engineer. Installation must comply with all applicable local codes.
DANGER
The control and power panels can deliver lethal voltages. Before servicing, open and tag all disconnect
switches.
Location and clearance
For optimum performance and trouble-free service, it is essential that the installation site meet the
location and space requirements for the model being installed.
It is important to ensure that the minimum service access space is maintained for cleaning and
maintenance purposes. Local health and safety regulations, or practical considerations for service
replacement of large components, may require larger clearances than those given in this guide.
Outdoor installations
The units can be installed on rail bracket, at least 6 in. (152 mm) higher above ground, at ground
level on a suitable, level foundation easily capable of supporting the weight of the unit, or on a
suitable rooftop location. In both cases an adequate supply of air is required. Avoid locations where
the sound output and air discharge from the unit may be a problem.
Select a location away from boiler flues and other sources of airborne chemicals that could damage
the condenser coils and steel parts of the unit.
If located in an area accessible to unauthorized persons, steps must be taken to prevent access
to the unit by means of a protective fence. This helps to prevent the possibility of vandalism,
accidental damage, or possible harm caused by unauthorized removal of protective guards or
opening panels to expose rotating or high-voltage components.
For ground level locations, install the unit on a suitable flat concrete base or rails that extends to
fully support the two side channels of the unit base frame. A one-piece concrete slab, with footings
extending below the frost line is recommended. To avoid noise and vibration transmission, do
not secure the unit to the building foundation. It is advisable, at the very least, to use neoprene
isolators.
On rooftop locations, choose a place with adequate structural strength to safely support the entire
operating weight of the unit and service personnel. Mount the unit on a concrete slab, similar to
ground floor locations, or on steel channels of suitable strength.
Space the channels with the same centers as the unit side and front base rails. This allows vibration
isolators to be fitted if required. Isolators are recommended for rooftop locations.
Ensure that the place of installation and operation can support the weight of the unit and any extra
operation and maintenance weights that may occur.
Noise sensitive locations
Ensure that the unit is not located next to occupied spaces or noise sensitive areas where unit noise
levels would be a problem. Unit noise is a result of compressor and fan operation. Use published
noise level information as part of your considerations.
