MS8C / MS8H (208-230V)
3. COMPONENT: OUTDOOR FAN MOTOR
ELECTRICAL CHARACTERISTICS:
* Power supply: 100~120V
* Frequency: 60Hz
* Number of poles: 2 or 4
* Output power: 90W.
* Description:
S Single-phase capacitor run asynchronous DC
motor with iron shell. This type of motor is reliable,
highly efficient, well structure, low noise output with
minimum vibration attributes.
S Run capacitor separate remotely mounted in the of
outdoor board
TROUBLESHOOTING:
Measure resistance between wire leads. If resistance is 0
ohms or infinite between any of the wire leads, replace
motor.

4. COMPONENT: ROTARY COMPRESSOR WITH
ACCUMULATOR
DESCRIPTION:
The rotary compressor is a 3-phase, direct-current (DC)
compressor. In a rotary compressor the refrigerant is
compressed by the rotating action of a roller inside a
cylinder. The roller rotates eccentrically (off-center) around
a shaft so that part of the roller is always in contact with the
inside wall of the cylinder.
A spring-mounted blade is always
rubbing against the roller. The two points of contact create
two sealed areas of continuously variable volume inside the
cylinder. At a certain point in the rotation of the roller, the
intake port is exposed and a quantity of refrigerant is sucked
into the cylinder, filling one of the sealed areas. As the roller
continues to rotate the volume of the area the refrigerant
occupies is reduced and the refrigerant is compressed.
When the exhaust valve is exposed, the high-pressure
refrigerant forces the exhaust valve to open and the
refrigerant is released. Rotary compressors are very
efficient because the actions of taking in refrigerant and
compressing refrigerant occur simultaneously.
TROUBLESHOOTING:
Check wiring connections at outdoor control board plug-in
and terminals of compressor.
