EMI AMERICA SERIES MULTI-ZONE HEAT PUMP CONDENSING UNITS INSTALLATION, OPERATION AND MAINTENANCE MANUAL P/N 240006458, Rev. 1.0 [01/07] This manual is intended as an aid to a qualiﬁed service personnel for proper installation, operation, and maintenance of these EMI America Series multi-zone heat pump condensing units. Read the instructions thoroughly and carefully before attempting installation or operation.

EMI AMERICA SERIES MULTI-ZONE HEAT PUMP CONDENSING UNITS DESCRIPTION INSTALLER SUPPLIED ITEMS 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.

INSTALLATION INSTRUCTIONS UNIT MOUNTING SECTION Side discharge unit allows for permanent mounting through the feet. This is highly recommended due to the vertical design of the unit. Accumulator Compressor Capacitor 1. Loosen the screws on left and right sides of the front panel. (Do not remove these screws.) Filter Driers Lag Bolts 5. Insert lag bolts through the holes in the bottom of the unit and tighten to secure. 2. Remove the screws on the front of the panel. 3. To remove front panel: 6.

ELECTRICAL WIRING INSTALLATION SECTION ! DANGER ! The EMI America Series condensing unit must: • Be connected to a properly grounded electrical supply with the proper voltage as stated on the rating plate. 3. Use only HACR type breakers or time delay fuses. Select the wire size according to the ampacity rating. 4. To access electrical connections and wiring diagram: a) Remove the screws on the side panel adjacent to the back panel.

REFRIGERANT PIPING INSTALLATION SECTION FIELD CHARGING NOTE: If operating superheat is more than 5°F above the chart value, add refrigerant. If below the chart value remove refrigerant. If below the limit line, remove refrigerant. Example (Using the 12,000 Btuh cooling chart): 1. Suction pressure is 65 psi. which equals 38° F on The R-22 Scale of the LowSide Gauge. 2. Suction line temperature taken at the unit is 70° F. 70° F minus 38° F equals 32° F superheat. 3.

MULTI-ZONE CONDENSER SEQUENCE OF OPERATION EMI America Series multi-zone heat pump condensers are designed to operate with EMI America Series indoor air handlers. Both the condenser (outdoor unit) and evaporator (indoor unit) have a high Volt service connection. Each is to be independently connected to the electrical service panel. (See the unit name plate for the correct breaker type and size). The outdoor and indoor units are also connected to each other through a low Volt interconnect wiring.
PAGE 17
MULTI-ZONE CONDENSER SEQUENCE OF OPERATION When the outdoor temperature falls below 35°F, compressor operation will cease. At that point the unit will switch on the indoor units electric heater to assume the heating demand, (second stage of heat). Note: For full operation the indoor unit must have an electric heater.
