Receiver separator Discharge Piping
The receiver separator discharge piping must be furnished by the customer. Refer to the appropriate
separator fitting location for a typical piping arrangement for these units. A minimum pressure valve and a
manual shut-off valve is supplied with each unit and must be piped into the customer’s system as indicated.
The minimum pressure valve is supplied to maintain approximately 77 pisg (531 kPa) in the air receiver tank
to ensure proper oil circulation and also to prevent excessive oil carryover into the customer’s air service
system. The manual shut-off valve must be installed between the minimum pressure valve and the
customer’s air service system to serve as an isolation valve.
In addition, whenever this unit is connected to a high volume customer’s service air system, a terminal
check valve must also be installed downstream of the minimum pressure valve and the isolation valve to
prevent air from the system from bleeding back into the compressor system on shutdown.
Wiring
The compressor is protected against overheating by a thermal-type discharge air temperature switch located
in the compressor discharge piping. A “normally-closed” type thermal switch, factory set at 248
°
F (120
°
C),
is supplied as standard equipment on these units. This switch is supplied for 12/24 volt DC. As an option,
this switch may be supplied for 125 volt AC. A thermal sensor switch, also set at 248
°
F (120
°
C), normally
closed, is provided as extra protection in the receiver separator. It is to be wired in series with the airend
temperature switch by the user. This switch is supplied for 12/24 volts DC, with optional AC switches
available as an option.
Driver
The installation of a CM Series Compressor with any drive such as a power take-off drive or a hydraulic
motor drive is very flexible. The proper rotation of the compressor is clockwise when viewed from the driver
end.
NOTE
Because the compressor is of the axial
screw type, the rotation cannot be changed.

splined shaft. Mounting flange is SAE “D”.
Alternatively, SAE “C” is available.
A drive shaft from the source of power take-off can alternatively be used to drive the compressor. It is
extremely important that the angularity of the drive shaft, including the universal joints, be within the limits
specified by the manufacturer. The power take-off shaft and the compressor rotor drive shaft must always
be parallel. This gives the same angle at each universal joint and prevents excessive wear. The forks of
the universal joint on the drive end must be installed parallel to the forks on the driven and universal. There
are many types of universal joints that can be used. However, a constant velocity universal joint as
previously described will reduce the possibility of torsional vibration. If a slip joint or spline is used on the
drive system, it should be placed between the two universal joints for best results.
