2. Introduction
The Ariazone 601 is a lightweight refrigerant recovery & recycling system for the onsite
mobile technician or small workshop operator.
This system has been designed to be very user friendly and efficient for every user.
Simply connect the Ariazone to the air conditioning system, switch on and walk away.
The 601 will take care of the rest.
The unit is designed to be:
- User friendly (fully automatic operation)
- Safe (built in high pressure and liquid control protection)
- Efficient (capacity app.200gr/min - liquid state)
- Durable (compressor with thermal protection)
- Universal (recovers vapor or liquid)
- Simple for maintenance (easy accessible filter)
3. Refrigerant Recovery & Recycling - Helpful Hints
The purpose of the Recovery & Recycling process is to take out refrigerant from the
system, condense, purify and putting it into a storage cylinder ready for re-use.
First task is to identify the refrigerant type and quantity in the system.
Use a recovery storage cylinder that has the same refrigerant in it. Must own at least
one tank for every refrigerant type serviced, plus extra for burnouts (if the system is
"burnout" you need special burnout cylinder and extra "burnout" filter prior to recovery).
Do not mix refrigerants in a system, a storage cylinder or anywhere else. Each type of
refrigerant must have its own recovery cylinder.
The key to a quick recovery is to get the liquid refrigerant out first, and then get the
remaining vapour out. Many systems don't have access ports on their lowest points
where the liquid is likely to accumulate. Also, trapped liquid refrigerant in a system
causes the recovery process to slow down, regardless of the size and the type of the
machine. To increase the recovery speed sometimes you need to boil off the trapped
liquid with a heat gun. If possible, remove Schraeder valves from system connections
and core depressor from the end of the hose. Deformed rubber grommet at the end of
the hose can restrict the flow of refrigerant.
To get the liquid out from large systems use push/pull method by using the pressure
created by the recovery machine. This method is mostly used on systems with a
receiver tank larger than 10kg (20lb) of refrigerant or when transferring from on cylinder
to another.
Another trick is to cool the storage cylinder. This will lower the pressure in the cylinder
and speed up the recovery process. This operation can be performed prior or during
the recovery.
