YORK INTERNATIONAL
1. Clearances – Recommended YORK required clearances to pre-
vent condenser air recirculation and faulty operation of units are as
follows:
Side to wall - 5'-0"
Rear to wall - 8'-0"
Front to wall - 8'-0"
Top - 50'-0"
Distance between adjacent units - 12'-0"
*No more than one wall can be higher than the top of the unit.
Failure to heed recommended clearances may result in reduced
system performance, nuisance shutdowns, and servicing problems.
The area within the clearances shown above and the area under the
unit must be kept clear of all obstructions that would impede free
air flow to the unit. In installations where winter operation is in-
tended and snow accumulations are expected, additional unit height
must be provided to insure full air flow.
2. Bottom of panel to be punched in field to allow for power wiring
entry. See page 9.
3. Use of isolators (optional) will increase height of unit approximately 6".
