Sea Frost BG 2000 Commissioning Procedure Evacuation with a Vacuum Pump, Evacuation Leak Test

Page 21

Disconnecting the gauge set on a static system may be done by rapidly unscrewing the hoses from the service ports.

Adding charge to a working system should be done through the suction side (blue) as liquid. The suction pressure must be monitored and not allowed to rise more then 15 PSIG above operating pressure.

VENTING THE CHARGE HOSE

WHEN ATTACHING GAUGES TO A CHARGED SYSTEM

Note: This procedure will vary with the type of gauges being used. Be sure to vent the charge hose to the gauge set before opening the valve to add refrigerant.

LIQUID CHARGING

REFRIGERANT IS EITHER a vapor or liquid. R-404a is a blend that may separate if vapor charged. To supply LIQUID to a system, keep the refrigerant canister in the inverted position (valve down). If properly handled the refrigerant will flash to vapor when charging.

COMMISSIONING PROCEDURE

EVACUATION WITH A VACUUM PUMP

Evacuation removes air, readying the system for charging.

Connect a gauge set to the service ports. (See "Access Port Location” page 33)

Connect the gauge center hose to a high vacuum pump. Start the pump and slowly open the low side/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). As the gauge reaches this low pressure close the valves on the manifold. 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 valves and continuing the evacuation process for 30 minutes or more. A micron gauge can be used to measure the vacuum. Proper dehydration and evacuation should be in the range of 200 to 500 microns.
