EMI America Series
DESCRIPTION
EMI offers the finest
When specifying heat pump(s), it is recommended that the matching indoor unit(s) be equipped with electric heat. All 9,000, and 12,000 Btuh circuit units are equipped with the Duratec Performance package which includes a large capacity suction accumulator with surge baffes and enhanced oil management, and a factory installed solid core filter drier. All 18,000 and 24,000 Btuh circuit units include a solid core filter drier and high pressure limit switch. The 18,000 Btuh circuits also include a large capacity suction accumulator with surge baffes and enhanced oil management.
NOTE: The crankcase heater is installed with 9,000 and 12,000 Btuh heat pumps.
CONTROLS and COMPOnENTS
(FACTORY INSTALLED OR SUPPLIED)
•Compressor and Fan Motor Contactor
•Capacitor
•Low Voltage Connections
•Large Capacity Suction Accumulator (9, 12, & 18 Only)
•High Pressure Control (18 & 24 Only)
•Solid Core Filter Drier
•Thermostatically controlled crankcase heater (9&12 Only)
•Common suction pressure access point
•Hard Start Capacitor
Thermostatically controlled crankcase heater – This feature energizes the crank- case heater only when needed, removes the heater from the electrical circuit at conditions where it’s not required, saving unnecessary Watts, and increasing overall system efficiency.
Multi-zone Heat Pump Condensing Units
SYSTEM OPTIONS
•Sea Coast Style Coated Coils /
•Wind Baffes - Louvers•
INSTALLER SUPPLIED ITEMS
•Power wiring
•Low Volt wiring - 18 AWG minimum
•Secure mounting pad or foundation
•Refrigerant piping
•Disconnect switch
ITEMS FOR CONSIDERATION
•Locate the unit as close to the indoor sec- tion as possible. Maximum length allowed is 100 equivalent feet.
•Avoid high traffiic areas and prevailing wind locations.
•Surface must be level.
•Mount unit above typical snow levels.
Ensure free air flow through the unit. Air must not recirculate from discharge to in- take. Air is drawn through the coil with side or top and 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).
