COMMISSIONING PROCEDURE

EVACUATION WITH A VACUUM PUMP

Evacuation removes air, readying the system for charging.

Connect a gauge set to the service access ports.

Connect the gauge center hose to a high vacuum pump. Start the pump and slowly open the suction gauge hand wheel. As the vacuum drops below 20 inches open both hand wheels fully.

EVACUATION LEAK TEST

Evacuate the system to the best vacuum (lowest pressure). Close the hand wheels to the pump. Observe the vacuum gauge and be sure the pressure remains constant for 5 minutes. If the pressure rises rapidly check all the connections again. Re-evacuate to the lowest pressure and test by holding a vacuum with the gauges closed. Be sure the system will hold this vacuum. Proceed by opening the hand wheels and continuing the evacuation process for 30 minutes or more. A micron gauge can be used to measure vacuum. Proper dehydration and evacuation should be in the range of 200 to 500 microns.

The evacuation leak check is a preliminary check and is not to be considered a system leak check.

NEW SYSTEM CHARGING

INTRODUCING INITIAL CHARGE

After the evacuation leak test and pump down shut off the hand wheels, disconnect the center hose from the pump, and connect it to the refrigerant supply. If the center hose does not have a check valve, vent the hose from can tap (refrigerant supply) to the gauge body. With the refrigerant can (12 oz. in the inverted (liquid) position, open the discharge hand wheel and feed in about 1/2 of a can of refrigerant (6 to 8 ounces). Close the hand wheel and begin an inspection of all the connections in the system. Begin leak check.

LEAK CHECKING

Leak checking is a very important step that should be done with diligence. A leak will cripple this system. Please take the time needed to be sure all connections are tight. Check every connection even the ones that were pre-made in manufacture.
