p. Mounting pad
To avoid extra vibration and noise resulted from direct contact between compressor footings and the base on which the
compressor is mounted, it is recommended to add mounting pads in between as the drawing below shown.

q. Temperature sensors Pt100 or Pt1000
To detect temperature of motor coil, Hanbell mounts Pt100 or Pt1000 sensor on motor coil as optional accessories.
This temperature sensor along with controller of the system monitor motor coil temperature and then control on/off of
liquid injection valve accordingly to provide suitable liquid injection as shown in the diagram below.

Note:
1. Liquid injection solenoid valve is controlled by the controller according to temperatures measured by Pt100/Pt1000
sensor.
2. Liquid injection sub solenoid valve is for auxiliary use. Its control logic is the same with that of aforementioned
liquid injection valve.
3. Hanbell suggests to control temperature of motor coil at 60 (not higher than 60 )
