10°F, contact your nearest YORK representative for application
requirements.
2. Operation above 115°F requires the Optional High Ambient Kit.
Contact factory.

YCAS 140-246 DIMENSIONS
(English)
NOTES:
1. Clearances - Recommended YORK clearances for peak performance, reliable operation and maintenance:
Side to wall 8'–0"*; Rear to wall 8'–0"; Control Panel End to wall 5'–0"*; Over the top - No obstructions allowed; Distance between
adjacent units 12'–0", (Walls should be no higher than the unit.)
*No more than one high wall can be higher than the top of the unit. The area within the clearances shown above and area under the unit
must be kept clear of all obstructions or clutter that would impede air flow to the unit. In installations where winter operation is intended
and snow accumulations are expected, additional unit height must be provided to insure air flow.
NOTE: Reduced clearances may be used due to jobsite restrictions or competitive recommendations. The unit will unload to prevent the
condenser pressure and motor current from exceeding the maximum limits and will continue to operate without nuisance high pressure
or motor current cutouts even though the air flow will be restricted at these conditions.
2. Cooler liquid connection sizes (inlet and outlet) 8" victaulic for all models.
3. Dimensions are in inches.
4. Spring isolators (OPTIONAL) will increase overall height of unit.
5. Modules have 1-1/8" of space between to facilitate maintenance.
