Manifold Gauge Valves - should be closed when connectrng
the manifold gauge set to the servrce port of the compressor
and the drscharge line% The suction gauge valve at the left is ;
opened to provrde a passagebetween the suctron gauge and
the center manrfold outlet. The discharge gauge valve at the .-
right IS opened to provide a passage between the discharge __
pressure gauge :and the center manifold outlet.
Detailed rnstructCons for proper use of the gauge set manifold z
dre contained in the text covenng each test and service
operation employrng these gauges.
_z
Suction Gauge - the lett side of the manitold~set is calibrated
to register 0 to -100 kPa (0 to 30 in. of vacuum) and 0 to 1,000 'I
kPa (0 to 150 psj). This gauge
IS
connected to the suction port
of the compressor.
-
Discharged Gauge - the rrght of the manifold set IS calibrated
to regrster 0 to 2,100 kPa (0 to 300 psi). For all tests this gauge
;
IS connected to the discharge port of the system
Center Manifold Outlet - provides the necessary connection
for a long service hose used when discharging the system,
using a vacuum pump to "pull a vacuum" before charging the __
system, and for connecting the supply of refrigerant when
chargrng the system.
