tubing run leading to the inlet of the compressor's suc-
tion service valve.
• The PWM valve must be mounted in a horizontal posi-
tion so the solenoid coil valve stem is in the vertical
position. Mounting in any other direction or imposing a
tilt angle may result in valve malfunction. See Fig. 40.
• The PWM valve has 1-1/8 ODF connections for brazed
installation. Do not braze the valve in-place with the
solenoid coil installed, and always wrap the valve in wet
rags to prevent any heat damage to the valve during the
brazing process.
• The PWM valve has a refrigerant flow directional arrow
located on the top of the valve to ensure correct horizon-
tal orientation. See Fig. 41.
