ALARMS

HIGH PRESSURE ALARM: Beeper advises when the pressure of the fluid in the circuit is too high 290 psi (20 bar). The recovery operation is automatically interrupted.

FULL TANK ALARM: Beeper advises when the tank is filled to more than 80% of maximum capacity, 24 lbs (10.9 kg). The RECOVERY operation is automatically interrupted (to cancel this alarm, charge one or more A/C systems before recovering any more refrigerant).

EMPTY TANK ALARM: Beeper advises when the quantity of refrigerant fluid contained in the tank is low, less than 3 lbs (1.36 kg).

VACUUM PUMP OIL CHANGE: Beeper advises after 15 hours of work of the vacuum pump; change the oil of the vacuum pump.

SERVICE ALARM: Beeper advises whenever the total recovered refrigerant amounts to 155 lbs (70 kg). To deactivate the alarm, replace the filters and the vacuum pump oil. A code for canceling the alarm is supplied with the spare filters.

ERROR MESSAGES

SYSTEM LEAKS: Error message displayed when the AC system

connections are not tight.

Solution: Verify the connections between the service hoses and quick couplers, and make another 5 min vacuum test only on service hoses . If the problem persists, delete the residual oil in the service hoses making a short 4 oz (100 g) charge in the service hoses and then a recovery, and repeat the 5 minutes vacuum test on service hoses.

NOTE: If the vacuum test on service hoses passes, means that the A/C system has a leak which must be localized using a leak detector.

WARRANTY

This product is warranted against any defect in materials and/or construction for a period of 2 (two) years from the date of delivery. The warranty consists of free-of-charge replacement or repair of defective component parts or parts considered defective by the Manufacturer. Reference to the machine serial number must be included in any requests for spare parts. This warranty does not cover defects arising from normal wear, incorrect or improper installation, or phenomena not inherent to normal use and operation of the product.

The manufacturer guarantees the perfect suitability of the materials used for packing, in terms both of composition and mechanical strength/resistance. The guarantee does not cover breakdowns attributable to damage suffered during shipping or warehousing or caused by the use of accessories not meeting manufacturer’s specifications, or to tampering with or repair of the product by unauthorized personnel. It is of utmost importance that the crates containing the machine be carefully inspected, upon delivery, in the presence of the shipping agent. We recommend performing inspection with extreme care, since damages to the crates due to shocks or dropping are not always immediately visible thanks to the shock-absorbing capacity of today’s composite packing materials. The apparent integrity of the packing materials does not exclude possible damage to the goods, despite the due care taken by the manufacturer in packing them.

NOTE: Regarding the above, the Manufacturer reminds the Customer that according to international and national laws and regulations in force the goods are shipped at the sole risk of the latter and, unless otherwise specified in the confirmation of order phase, the goods are shipped uninsured. The Manufacturer therefore declines any and all responsibility in merit of CLAIMS for damages due to shipping, loading and unloading, and unpacking.

The product for which repair under guarantee is requested must be shipped to the manufacturer under the customer’s exclusive responsibility and at the customer’s exclusive expense and risk. In order to avoid damage during shipping for repairs, the Manufacturer’s original packing must always be used.

The manufacturer declines any and all responsibility for damage to vehicles on which recovery/recycling and recharging are performed if said damage is the result of unskillful handling by the operator or of failure to observe the basic safety rules set forth in the instruction manual. This warranty replaces and excludes any other warranty or guarantee that the seller is required to provide under law or contract and defines all the customer’s rights in regard of faults and defects and/or scarce quality in the products as purchased.

The warranty will expire automatically at the end of the twentyfour-month period or whenever one of the following occurs: failure to perform maintenance; use of improper maintenance procedures; use of unsuitable lubricants and/or tracer fluids; inept or improper use; repairs performed by unauthorized personnel and/or with non-original spare parts; damage caused by shocks, fires, or other accidental events.
