1 - I N T R O D U C T I O N
The machine described in this user and maintenance guide is a semi-automatic, multifunctional
digital-setting system for operation with vehicle air conditioning (A/C) plants with functions for gas
recovery, used oil discharge, vacuum, leakage control, oil injection, gas injection and discharge of
incondensable gases, all managed by a microprocessor and an electronic precision weighing
machine. It is equipped with analogic pressure gauges with silicon absorber pads with a
diagnostics section for monitoring operating pressures of any type of conditioning or refrigerant
plant installed on vehicles working with R12 (model Pratika/12) or with R134-a (model Pratika/134).
The PRATIKA system, thanks to the digitally controlled unit means that all operations can be
carried out while fully respecting the environment.
•
Recovery:
allows recovery both of the refrigerant fluid as well as part of the oil that it
contains, automatically overseeing separation of the two components and relative storage. The
contaminated oil is recovered in an apposite outside graduated container, while the fluid following
reprocessing by dehydration filters, is stored in a cylinder for the purpose. The electronic precision-
weighing machine automatically determines the quantities.
•
Re-injection:
the reprocessed refrigerant fluid can be recycled (after injection with new oil)
using the method adopted by the operator. It is also possible to add new refrigerant fluid as
required.
•
Vacuum:
it is possible to depressurise the A/C plant to the maximum level in the set time,
maintaining a vacuum. In this way, it is possible to completely eliminate any humidity present in the
system and check the vacuum seal for possible leaks.
The machine comes complete with connection cables for connection and liquid injection inside the
A/C plant.
Do not use the machine for any other purpose other than which it was designed. In the
case of demolition or hauling away, check the legislation codes that are applicable in
your Country (note that the machine contains refrigerant fluids and we therefore
recommend demolition by specialised operators).
The machine is supplied with two distinct models for two types of refrigerant. Do not use
the same model for both types of fluids.
