Sanyo SAP-CMRV1926EH English, Table, Be sure to completely insert, the hex wrench before, R134a

(4)With the “Lo” knob of the manifold valve open and high-pressure valve (“Hi”) closed completely, run the vacuum pump. Run the pump until the pres- sure is –101 kPa (–76 cmHg). The operation time for the vacuum pump varies with tubing length and the capacity of the pump. The following table shows the amount of time required for evacuation:

Table 5

Required time for evacuation when capacity

of 100 liter/h vacuum pump is used

20 min. or more

NOTE

The required time in the above table is calculated based on the assumption that the ideal (or target) vac- uum condition is around 10 mmHg abs.

(5)With the vacuum pump still running, close the “Lo” knob of the manifold valve. Then stop the vacuum pump. Fully close the low-pressure valve and stop the vacuum pump. (Wait 1 – 2 minutes and check that the manifold gauge pointer does not return. If it does return, find and repair the leak, then apply the vacuum again.)

(6)With a hex wrench, turn the valve stem on the nar- row tube service valve counter-clockwise by 90 degrees (1/4 turn) for 10 seconds, and then turn the stem clockwise to close it again.

CAUTION	Be sure to completely insert
	the hex wrench before
	attempting to turn the valve.

(7)With a standard screwdriver, turn the wide tube service valve stem counterclockwise to fully open the valve.

(8)Turn the narrow tube service valve stem counter- clockwise to fully open the valve.

(9)Loosen the vacuum hose connected to the wide tube service port slightly to release the pressure. Then, remove the hose.

(10)Leak test all joints at the tubing (both indoor and outdoors) with liquid soap. Bubbles indicate a leak. Be sure to wipe off the soap with a clean cloth.

CAUTION	If a CFC gas detector is used,
	use a special detector for HFC
	refrigerant (such as R410A and
	R134a).
