EMI AMERICA SERIES
DESCRIPTION
EMI offers the finest dual zone heat pump outdoor units in the ductless split market, the S2HA Condensing Unit. The S2HA allows the installation of two circuits from a single outside location when space or aesthetic requirements limit the use of the number of cabinets outdoors. Each zone is independent so no mixing of refrigerant occurs.
When specifying heat pump(s), it is recommended that the matching indoor unit(s) be equipped with electric heat. The S2HA will operate down to 35°F outdoor temperature, at which point it will initiate change over to electric heat and shut down the condenser. All 9,000, and 12,000 Btuh circuit units are equipped with the Duratec Performance Package which include a large capacity suction accumulator with surge baffles and enhanced oil management, a factory installed solid core filter drier and loss of refrigerant charge protection.
NOTE: The crankcase heater is in- stalled with 9,000 and 12,000 Btuh heat pumps.

ITEMS FOR CONSIDERATION
•Locate the unit as close to the indoor sec- tion as possible. Maximum length allowed is 100 equivalent feet.
•Avoid high traffic areas and prevailing wind locations.
•Surface must be level.
•Mount unit above typical snow levels.
Ensure free flow of air through the unit. Air must not recirculate from discharge to in- take. Air is drawn through the coil with side, or top discharged through the fan grille. A minimum 48” clearance is necessary for the condenser discharge. Intake (coil side) clearance is 12” minimum. Consider how power will be run to the unit from the power source. Refrigerant piping must be a direct line to the indoor unit.
Heat pump units produce condensate in the heat pump mode. Water will drain from the unit at the base. Place the unit so as not to create a hazard for pedestrians.
SITE PREPARATION
Place the unit on a flat concrete surface or pad if on the ground. Roof mounting should use a build up platform. Piping is through the wall or roof directly to the unit. In areas of heavy snowfall, condensers should be set above the level of maximum anticipated snowfall (12” is usually adequate).
