Connect the terminal plug from the electronic unit to the compressor terminal. Mount the electronic unit
on the compressor by snapping the cover over the screw head.

Power supply
The electronic unit must always be connected directly to the battery poles . Connect the plus to + and
the minus to -, otherwise the electronic unit
will not work. The electronic unit is protected against reverse battery connection.For protection of the
installation, a fusemust be mounted in the + cable as close to the battery as possible. 15A fuse for
12V and 7.5A fuse for 24V circuits are recommended.If a main switch  is used, it should be rated to a
current of min. 20A. The wire dimensions in Table. 2 must be observed. Avoid extra junctions in the
power supply system to prevent voltage drop from affecting the battery protection setting.

Battery protection
The compressor is stopped and re-started again according to the decided voltage limits measured on the
+ and - terminals of the
electronic unit. The standard settings for 12V and 24V power supply systems
appear from Table. 3. Other settings  are optional if a connection which includes a resistor 
is established between terminals C and P.

The thermostat is connected between the terminals C and T. Without any resistor in the control circuit,
the compressor with electronic unit
will run with a fixed speed of 2,000rpm when the thermostat is
switched on. Other fixed compressor speeds in the range between 2,000 and 3,500 rpm can be obtained
when a resistor is installed to adjust the voltage (v) of the control circuit. 

A fan can be connected between the terminals + and F. Connect the plus to + and the minus to F.
Since the output voltage between the terminals + and F is always regulated to 12V,a 12V fan must be
used for both 12V and 24V power supply systems.The fan output can supply a continuous current of
0.5A avg . A higher current draw is allowed for 2 seconds during start.

A 10mA light emitting diode(LED) can be connected between the terminals + and D. In case the
electronic unit records an operational error, the diode will flash a number of times. The number of flashes
depends on what kind of operational error was recorded. Each flash will last 1/5 second. After the actual
number of flashes there will be a delay with no flashes, so that the sequence for each error recording is
repeated every 3 minutes

100% high quality.
Perfect to replace your old or broken car refrigeration air compressor.
Unique charm, wear-resisting durable and undamage.
Easy to install.
No drilling and cutting required.
