CLT1 – Test tool for externally controlled compressors
Dear Customers,
Thank you for making the decision to purchase the CLT1 from Adiator.
The CLT1 can be used for testing all clutchless, direct drive, externally controlled
compressors, all year round, no matter how low or high the ambient temperature is.
The CLT1 has been designed “by technicians for technicians.”
Technical Application
The CLT1 will provide a direct power supply to the electronic control valve on all
clutchless, direct drive, externally controlled A/C compressors without having to
connect to the vehicle’s electrical system. Its simple, easy-to-use format will greatly
save valuable A/C diagnostic time. The CLT1 allows you to expand your A/C
diagnostic skills.

Preparations prior testing the vehicle
• The vehicle should be at operating temperature.
•Set the air conditioning system to maximum cold.
•Set the speed of the blower on maximum.
•Only use vents in the centre of the car (close others).
•The airflow should be positioned and set at face vent level. Position a temperature
probe in the centre allowing you to measure the air outlet temperature.
•Connect a gauge or A/C service station to allow you to view the operating
low and high side system pressures.
•Disconnect the plug on the A/C compressor control valve or control valve harness.
Connect the appropriate CLT1 Universal, VAG-group or Denso harness.
• Connect the simulator to the disconnected control valve plug.
Shows you an example of the CLT1 connected to a compressor.
General Advice
The 12V battery power supply should be maintained for the protection of the test
equipment and the compressor.

Connecting the battery
Attach the 12V battery clamps to the vehicle battery ensuring the correct polarity
connections; otherwise the CLT1 unit will be damaged.
This means:
Red = positive = plus = 30
Black = negative = ground = 31
Prevent error codes with CLTSIM
To prevent storing an error code in the vehicle’s electronic fault code memory system,
use the simulator (Pt No.: CLTSIM). Connect the simulator to the disconnected control
valve plug.
The CLTSIM has a universal 2-pin connector that will fit all vehicle control valve harness
applications. For vehicles with a single wire harness, connect one of the pin connectors
to ground 31.
