5. Operation and maintenance
5.1 Compressor start-up
PRE-START CHECKING- Table below shows the required procedures and checkpoints before starting-up the compressor during
commissioning or initial operation of the unit.
Items
Things to be checked
States or standard values
1. Accessories
1.
Oil level
2.
Oil heater
3.
System valves status
4.
Solenoid valves
5.
Capillary
1.
Higher than the middle line of oil level sight glass
2.
Should be kept energizing after compressor shut down.
3.
Opened
4.
Fixed
5.
No serious distortion or damaged
2. Electrical system
1.
Voltage of main power
2.
Voltage of control circuit
3.

terminals connection.
5.
Grounded
6.
Capacity of electrical accessories
7.
7. Settings of switches, sensors and
controllers.
1.
Electricity voltage should be kept within 5
%
to the
rated voltage, instant maximum voltage drop while
starting should be less than 10% to the rated voltage.
2.
Standard voltage is 220V. Maximum voltage is 230V.
If there is other demand, contact HANBELL.
3.
Insulation resistance value should be above 5M
Ω
.
4.
Power terminals are firmly fixed on terminal block and
well insulated. Keep wire cables away from heat
source and sharpened metal. Power terminals are fixed
firmly and well insulated. Terminal screw and block
are both required.
5.
(Ruled by the local Electricity Regulations.)
6.

2.
Leakage test
3.
Bolts to fix the compressor.
4.
Vacuum before compressor start.
(Vacuum procedures following p.)
1.
Fixed firmly.
2.
No leakage.
3.
Fix the compressor tightly.
4.
Following EN378-2 and vacuuming compressor are a
must before the system starts.
4. Safety devices
1.
Motor coil sensor (thermistor)
2.
Discharge sensor (thermistor)
3.
Controller
1.
Connected in series with discharge sensor to controller.
2.
Connected in series with motor sensor to controller.
3.
Closed circuit with N.C. & N.O.
