Logika - use and maintenance guide

page

The machine described in this user and maintenance guide is an 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 and gas 

injection, all managed by a microprocessor and an electronic precision scale. 

Do  not  use  the  machine  for  any  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.

1.  Introduction

•  

Electronic management system

: it allows the whole process to be administered through

    a microprocessor.
•  

Electronic precision scale for weighing of gas

: it can weigh up to a maximum of 10 Kg.

     of refrigerant with a margin of error of 10 grams and is programmed to interrupt the

     RECOVERY and CHARGING functions if pre-set for this purpose or should the quantity of

     gas exceed the set limits.
•  

Electronic precision scale for weighing of oil injection

: it can weigh up to a

     maximum of 500 grams with a margin of error of 10 gr.
•  

Compressor for refrigerant gas recovery

.

•  

Anti-acid and dehydration filters

 (n. 3) with hight absorption capacity of water

     guaranteeing excellent autonomy.
• 

Infeed gas still

 with automatic regulation of refrigerant flow and separated oil coming

     from the A/C system with discharge of oil coming from the same.
•  

Oil separator

: positioned immediately after the compressor with automatic oil return at

    the end of the cycle.
•  

Cylinder for refrigerant gas recovery

, equipped with an electronically controlled

     thermostatic resistor and discharge of incondensable gases.
•  

Two-stage high-performance vacuum pump

.

•  

Control panel

 with digital commands.

•  

Analogic pressure gauges

.

•  

Refrigerant service valve (Ref. Service)

: allows refrigerant contained in the internal

     cylinder of the unit to be sent to a suitable outside container for the purpose.
•  

Solenoid valve

 for the discharge of the incondensable gas which are in the bottle.

•  

Discharge valve

 

for oil coming from the A/C system

.

•  

High-performance flexible hoses

 (n. 2) with rapid coupling and with manual opening

    (screw mechanism) for R134a and R12.
•  

Oil dosing devices

 (n. 2) 500 cc.
