Operation and Maintenance
The S1CG/S1HG and S2CG/S2HG outdoor
sections are the compressor bearing units of
the system. It operates at the command of the
indoor section or room thermostat. Therefore,
the system 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
collects on the air coil, it should be cleaned
by "back-flushing" with a spray of water or
vacuuming.
TURN OFF POWER SUPPLY
. Outdoor units may be cleaned or
FIRST
waxed if desired. Use a non-abrasive car wax
(on metal surfaces only).
This unit is equipped with a permanently
lubricated motor. Although oiling is not nec-
essary, 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
service agency only
