Do not charge the
straight cool
units on cold days unless weigh-
ing in the charge. The
heat pump
systems may be charged in
heat cycle at any temperature.
These units uses a heat cycle
TXV and cannot be charged to superheat; use weight or
subcooling method only.

a scale.
SPECIFIC CHANGES
All EMI products are subject to ongoing development programs
so design and specifications may change without notice. Please
consult the factory for more information.
STARTING THE UNIT
• Before starting the unit in cool weather, power the system
24 hours before attempting to start if a crankcase heater is
installed.
• Do a final system check using the superheat/subcooling
method. Record results on Test Unit Data Sheet.
• Remove gauge set. Mount all access panels and make sure
they are properly secured.
• Make final visual inspection and repair any deficiencies.
NOTE:
A hard start kit may be required for units in low volt-
age/frequent cycle applications.
OPERATION AND MAINTENANCE
The EMI AmericaSeries 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 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 maintenance. 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 vacuuming.
TURN
OFF POWER SUPPLY FIRST.
Outdoor units may be cleaned or
waxed if desired. Use a non-abrasive car wax.
This unit is equipped with a permanently lubricated motor. Al-
though oiling is not necessary, adding a few drops through the
oiling ports twice yearly will extend the life of the motor. Do not
over oil.
Panels should remain on the unit at all times. Service should be
performed by a QUALIFIED service agency only.
