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 section or room thermostat. Therefore, the operation will be described in the manual pertaining to the indoor section.

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-fushing" 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.
