void the warranty. A Field installed low- ambient kit is good for operation down to 32º F. This is accomplished by cycling the condenser fan on and off, which will in turn maintain a constant low side pressure pro- viding a steady cooling effect and keeping the air handler from
Items for Consideration
•Locate the unit as close to the indoor section as possible. (see Tubing Specifications chart on pape 7.)
•If the unit is used for low ambient cool- ing down to 32°F, this option must be specified to prevent system damage.
•Avoid high traffic areas and prevailing wind locations.
•Surface must be flat and level.
•Mount unit above typical snow fall levels.
Ensure free flow of air through the unit. Air must not recirculate from discharge to intake. Air is drawn through the coil and side discharged through the fan grille. A minimum 48" clearance is necessary for the condenser discharge. Rear intake (coil side) clearance is 12" minimum. Consider how power will be run to the unit from the power source. Refrigerant piping should be a direct line to the indoor unit.
Installation Instructions
SITE PREPARATION
1.Place the unit on a flat concrete surface or pad if on the ground. Roof mounting should use a build up platform to avoid intake of hot air from the roof.
2.In areas of heavy snowfall, condens- ers should be set above the level of maximum anticipated snowfall (12" is usually adequate).

Unit Mounting Instructions
S1C is shown
Side discharge unit allows for per- manent mounting through the feet. This is highly recommended due to the vertical design of the unit.
1.Loosen the screws on left and right sides of the front panel. (Do not remove these screws.)
2.Remove the screws on the front of the panel.
3.To remove front panel:
4.Slide front panel forward to clear side screws and remove.
