  • Working Conditions: 0 to 40°C ambient temperature, up to 80% humidity, 2000m altitude.
  • Noise Level: < 70 dB (A).
  • Fuse: 10 amp/250V (slow blow type).
  • Measuring Instrument Category: I category (Not to be mixed with II, III, IV category).
  • Approvals: EN 61010-1 Electric safety, EN 55014-1 EMC-CE.

Usage Features:

The unit is designed for ease of use, with a clear LCD display and intuitive icons.

  • Preparation: The manual outlines steps for unpacking, securing the unit head, connecting service hoses (blue for low-pressure/suction, red for high-pressure/discharge), and connecting the power lead to an earthed outlet.
  • Main Components: Key components include LP and HP digital displays, a touch screen, a printer, USB port for wireless temperature sensor, connecting cable, new oil/UV dye injection vessels, a recovered oil drain ball valve, suction and discharge ports with pre-filters, service hoses storage ports, ON/OFF switch, power inlet socket, and various covers and wheels for mobility and protection.
  • Switching On: Upon startup, the machine displays remaining hours before maintenance and performs a self-purge and hose evacuation to prevent non-condensable air from entering the cylinder, ensuring refrigerant purity. The main menu then appears on the LCD.
  • Icons: A comprehensive set of icons guides the user through operations, indicating states like "machine requires servicing," "self purging," "updating software," "set up/adjusting settings," "set weight," "edit," "please wait," "return to previous menu," directional arrows for scrolling, "minus/decrease," "plus/increase," "good/function completed," "bad result/cancel," and "set time."
  • Operational Icons: Additional icons indicate power status, A/C system refrigerant presence, recovery status (partial or full), refrigerant cylinder status (full, change cylinder, or transfer), pause function, evacuation status, leak test status, oil charge status, oil injection from different vessels, dye injection, and refrigerant charging.
  • Printer: The unit includes a printer for reports, with a green LED indicating its status (ON, blinking for error/no paper, OFF). Paper specifications are 57-58mm width and 80μ max thickness. Instructions are provided for opening the cover, loading paper, and closing the cover.
  • Refrigerant Transfer: Procedures are detailed for filling the storage cylinder from both refillable and disposable cylinders, emphasizing correct hose connections and valve operations.
  • A/C System Connection and Testing: Clear instructions are given for connecting service hoses to the vehicle's A/C system, ensuring proper port connections (blue to low-pressure, red to high-pressure). The unit's digital displays show suction and discharge pressures, with a bar graph providing an estimation of good, fair, or bad working pressures, color-coded for easy interpretation.
  • Recovery & Recycling Mode: This mode is used to recover refrigerant from the A/C system. The process involves selecting the recovery icon, confirming the desired amount of refrigerant (or 100% for full recovery), and starting the process. The machine self-purges and evacuates hoses before recovery. During recovery, the display shows the amount recovered. The process includes pauses to allow remaining refrigerant to boil off and re-runs if pressure increases. After recovery, the machine drains and measures recovered oil, displaying total recovered refrigerant and oil.
  • Evacuation Mode: This mode removes air and moisture. The user sets the evacuation time, selects the A/C service port(s), and can perform a leak test after evacuation.

Maintenance Features:

  • The unit is designed for long-lasting operation and high reliability.
  • Maintenance should be carried out according to manufacturer recommendations using only original parts.
  • Maintenance must be performed by an authorized technician.
  • The manual emphasizes safety procedures, including wearing protective clothing and safety glasses, avoiding refrigerant inhalation, using only R134a refrigerant, keeping the machine dry, and not tampering with safety controls.
  • Electrical safety is paramount: connect to an earthed power point, never operate with a damaged power lead, and always unplug the power lead before removing any protective cover.
  • Ventilation openings must not be covered during operation.
  • Only non-aggressive substances should be used for cleaning.
  • The unit does not contain or operate with flammable refrigerants.
  • Environmental information highlights the importance of proper disposal of electrical and electronic equipment, including batteries, and recycling internal and external packaging to protect the environment.
