The Maintenance Kit containing Vacuum Pump, Hoses and Manometers, "T/KIT1", contains the necessary elements to carry out the loading and unloading of a cooling system.

The system consists of a vacuum pump, spark free to avoid fire hazards, which provides the necessary pressure gradient for the refrigerant gas to enter or leave the circuit.

A set of flexible hoses suitable for different pressure ranges is supplied, which incorporate the necessary connections to connect the refrigerant storage vessel to the circuit. In addition, they are made of low permeability rubber to minimize product loss. Finally, the "T/KIT1" kit includes a set of pressure gauges and a pressure and temperature bridge-analyzer for air conditioning systems and two-way refrigeration systems with scale for the most common commercial refrigerants.
