9. Connecting Ariazone 5001FA to the A/C system
Use the service hose (5) quick-connect couplers to connect the hoses to the A/C system service
ports, bearing in mind that BLUE must be connected to the low-pressure (suction) side and RED
to high pressure (discharge) side.
If the system is equipped with a single service port, connect only the relative hose.
Note: Before connecting the quick couplers, clean the a/c ports of any foreign material.
Winding the quick coupler hand wheel clockwise, will allow the refrigerant to flow through the
hoses. Turning hand wheel in opposite direction, the flow will be closed. If there is any refrigerant
in the air-conditioning system, the pressure gauges will indicate a pressure rise.
Important: Console manifold hand valves (4) need to stay closed, not to allow
refrigerant to enter the service equipment until the required function has been
selected.
Ariazone 5001 gauges (suction & discharge) are important and useful instruments, the operator
should have basic understanding between gauge reading and air-conditioning system operation,
in order to correctly diagnose any possible system malfunction.
