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.

OPERATION AND MAINTENANCE

The EMI America Series outdoor section is the compressor bearing unit of the system. It operates at the command of the indoor sec- tion or room thermostat. Therefore, the opera- tion will be described in the manual pertaining to the indoor section. The S & T series (S2HA, T2HA, T3HA & T4HA) will cease compressor operation at 35°F outdoor temperature. If in heating mode, the electric heat will take over when the compressor ceases operation.

EMI units are designed and constructed for reliability and long life with minimal main- tenance. You can assure peak operating efficiency by regularly inspecting for free air passage into and through the coil. If debris collect on the air coil, it should be cleaned by "back-flushing" with a spray of water or vacu- uming. TURN OFF POWER SUPPLY FIRST. Outdoor units may be cleaned or waxed if desired. Use a non-abrasive car wax.

Panels should remain on the unit at all times. Service should be performed by a QUALI- FIED service agency only.

SPECIFIC CHANGES

All EMI products are subject to ongoing de- velopment programs so design and specifi- cations may change without notice. Please

consult the factory for more information.

GENERAL RECOMMENDATIONS

Do not charge the straight cool units on cold days unless weighing in the charge. The heat pump systems may be charged in heat cycle between 35 and 75°F. These units use a heat cycle TXV and cannot be charged to superheat; use weight or subcooling method only.

Charging should be done with a dial-a- charge or weighed in with a scale.
