5.1.1 The Controller is connected to the battery d irectly, wrong connect the poles doesn t destroy
the compressor and controller, but the compressor d o not work;
5.1.2 The fuse must be connected in the + cable to protect controller, which close to the power
supply, 15A fuse for 12VDC and 7.5A fuse for the 24VDC are recommended;
5.1.3 If a main switch is used, it should be rated to current of min. 20A;
5.1.4 To prevent voltage dropping, please avoid ex tra junction in the power supply system.
5.1.5 A Light Emitting Diode(LED) for compressor o peration monitoring can be connected
between the terminals + and D .
Operational errors will cause the LED to flash a nu mber of times. The number of flashes
depends on what kind of operational error was recor ded. Each flash will last 1/4 second and
each error will repeat every 4 seconds. Operational errors show by Table 5, please see it in
page 6.
5.1.6 If a cooling fan is used. It must be connect ed to electronic unit terminals + and F, only use
12VDC fan , no matter what power supply you are usi ng;
5.1.7 A Thermostat is connected between the termin al C and T of the electronic unit. It will start
or stop the running of compressor automatically;
5.1.8 A Resistor can be connected between terminal C and T, it allows you to adjust the speed of
the compressor, the relationship between the resist or and the compressor speed shown by
Table 3; please see it in page 3.
5.1.9 To ensure sufficient battery power for co mpr essor and avoid permanent damage to the
battery because heavy discharge. A battery protecti on resistor is connected between
terminal C and P, the different resistor will get t he different voltage protection, the details is
showed by Diagram 4;

Controller calibrator to the applied voltage automa tically, when the battery voltage is lower
than 17 VDC, The controller consider it is working in a 12 V DC system, and When the voltage is
higher than 17 VDC The controller consider it is wo rking in a 24 V DC system.
resistor is connected between C - P , the operating voltage range could be
9.6V 31.5V, this means
TD35 VS and TD50 VS are very suitable for
application.
5.5 Error Indication
If the start failed, the controller will attempt r estarting every 60s, until a successful start is
achieved. The following Table shows the Error Type and reason.

7.3 More than two layer package of compressors is no t available, and avoid any rolling during
loading and unloading.
7.4 After consignment, it is better store the compres sors not more than 6 months.
8 Precautions
8.1 The compressor is only allowed to be connect ed to a 12/24VDC system, it is forbidden to
connect compressor directly with an AC power supply.
8.2 The back gas tube on refriger ation system must be connected with the suction tube on
compressor, not the process tube on compressor; otherwise the compressor can t work in gear.
8.3 Please mount the compressor into the refrigerat ion system quickly in 10 minutes after uninstall
the tubes of the compressor (suggest to uninstall the process tube first).
8.4 The maximum ambient temperature of the compress or operation is 55 .When continuously
operating under the maximum ambient temperature 55 , the max condensing pressure and the
peak pressure should not exceed 1.75MPa and 2.17MPa.
8.5 Balance pressure 55 start the compressor the pressure in the compressor could not more
than 0.49MPa.
8.6 Do not operate the compressor before polyester is charged.
8.7 The refrigerant charge should be less than 200g
8.8 The interval of compressor operation Operation is more than 3 minutes, and the stoppage is
more than 3 minutes too.
8.9 Special attention Do not use the compressor as a vacu um pump, and do not start it under
vacuum status too.
8.10 The refrigeration system should minimize the c ontent of chlorines and moisture, and must be
free of paraffin and silicon.
8.11 In order to make the compressor work prope rly, the following cable dimensions must be
observed.
