Principles Of Operation; Setup; Release Refrigerant Scale; Lock Refrigerant Scale - Wow WAC 2200 Instruction Manual

PRINCIPLES OF OPERATION

In a single series of operations, the machine permits recovering and recycling refrigerant fluids
(R134a or R1234yf, depending on machine model) with no risk of releasing the fluids into the
environment, and also permits purging the A/C system of humidity and deposits contained in
the oil. The machine is in fact equipped with a built-in evaporator/separator that removes oil
and other impurities from the refrigerant fluid recovered from the A/C system and collects them
in a container for that purpose. The fluid is then filtered and returned perfectly recycled to the
bottle installed on the machine. The machine also permits running certain operational and seal
tests on the A/C system.

SETUP

The machine is supplied fully assembled and tested. Referring to Figure 3, mount the hose
with the BLUE quick-connect coupling on the male threaded connector indicated by the BLUE
LOW PRESSURE symbol and the RED quick-connect coupling on the male threaded
connector indicated by the RED HIGH PRESSURE symbol.
Remove the protections under the refrigerant scales as follows:

Release refrigerant scale:

- In order to remove the protections under the refrigerant scale the screw (ref.1, Fig.4)
has to be unscrewed until it full stops
- Connect the machine to the electrical supply and switch it on
- Check if the value of refrigerant scale is correct.

Lock refrigerant scale:

NOTE: in the event that the equipment has to be transported, the refrigerant bottle scale
should be locked in place as follows:
1. Switch the machine on.
2. Tighten the screw (ref.1, Fig.4) until the display signals ZERO availability.
