How do you recover air from a refrigerant line?

Set the recovery machine to recover. 5. PURGE THE HOSES OF AIR (this is done a little bit differently than in direct recovery.) a. Open the liquid line service valve or core tool and then loosen and unseat the hose connected to the liquid port on the recovery tank until refrigerant is present and then retighten.

How do you know when to use more refrigerant during recovery?

The more refrigerant the system holds, the more time you’ll save. Tip: Using an inline sight glass during push-pull recovery will allow you to determine when the liquid flow has stopped visually. 1. Start with all valves closed (recovery cylinder, recovery machine, manifold, hoses.)

How do you use a push pull refrigerant recovery system?

An example of a system set up for the push-pull method of refrigerant recovery. Connect a hose from the discharge port of the recovery unit to the vapor side of the HVAC system. Then, connect another hose from the liquid side of the HVAC system to the sight glass and on to the liquid side of the recovery tank.

How do I connect the recovery tank to the HVAC system?

Connect a hose from the discharge port of the recovery unit to the vapor side of the HVAC system. Then, connect another hose from the liquid side of the HVAC system to the sight glass and on to the liquid side of the recovery tank. Finally, connect a hose from the vapor side of the recovery tank to the suction port of the recovery unit.

How do you recover refrigerant from an air conditioner?

Before beginning recovery, check the positions of all service valves and the oil level of the recovery unit. Recover the refrigerant into the system’s own receiver or storage tank if it has one. It is most efficient to recover liquid first (from the system’s liquid line), then vapor.

How do you clean the air out of a refrigerant line?

PURGE THE HOSES OF AIR (this is done a little bit differently than in direct recovery.) a. Open the liquid line service valve or core tool and then loosen and unseat the hose connected to the liquid port on the recovery tank until refrigerant is present and then retighten.

How do you know when to use more refrigerant during recovery?

The more refrigerant the system holds, the more time you’ll save. Tip: Using an inline sight glass during push-pull recovery will allow you to determine when the liquid flow has stopped visually. 1. Start with all valves closed (recovery cylinder, recovery machine, manifold, hoses.)

What size refrigerant line do I need for a recovery machine?

In general, the larger the hose, the less friction on the flow of refrigerant, and the quicker the recovery time. Many contractors and technicians are now using 3/8-inch lines for the input to the recovery machine, even if those lines originate out of 1/4-inch fittings.

How do you recover air from an air conditioner?

1. Start with all valves closed (recovery cylinder, recovery machine, manifold, hoses.) 2. Setup hoses as shown in the diagram. 3. ZERO/TARE the refrigerant scale. 4. Set the recovery machine to recover. 5. PURGE THE HOSES OF AIR (this is done a little bit differently than in direct recovery.) a.

How do I use the fan on my tank recovery machine?

• With many recovery machines, you can use the fan to draw air over the tank. • Water will work even better, but you’ll need water flow. • Cool down the refrigerant!

How do I Fill my recovery tank?

With the recovery tank fill calculator, all you need to do is supply the tare weight and water capacity, adjust the maximum temperature to your conditions, and select the type of refrigerant you’re using from a drop-down menu.

How do you cool down a refrigerant tank?

• With many recovery machines, you can use the fan to draw air over the tank. • Water will work even better, but you’ll need water flow. • Cool down the refrigerant! This one tends to be your best bet if you’re dealing with large volumes of refrigerant – there are heat exchangers available for just for this purpose.
