INSTALLATION.
3.1
THE FOLLOWING INSTRUCTIONS ARE TO BE FOLLOWED ONLY AFTER
SECTION 2.0 HAS BEEN COMPLETED.
3.2
FOR BENCH-MOUNTED UNITS UTILIZING "HOUSE" AIR AS THE PRIMARY AIR
SUPPLY TO THE PURE AIR GENERATOR, connect the "house" air adapter,
Figure 2 (1), to the EXTERNAL SOURCE fitting on the rear of the pure air
generator, as shown in Figure 2. The stainless steel tubing supplied with the
"house" air adapter will support the adapter rigidly when all fittings are properly
tightened.
NOTE:
SINCE MOST "HOUSE" AIR SUPPLIES ARE FROM OIL-PUMPED
SOURCES, IT IS MANDATORY THAT THE AADCO INSTRUMENTS'
"HOUSE" AIR ADAPTER, AND ONLY THIS ADAPTER, BE USED. This
is an oil-indicating filter and dramatically indicates when depletion is
imminent. Use of this filter avoids contaminating the purification reactor
and jeopardizing the purity of the output air.
3.3
If a source selector valve, Figure 1 (5), is present, place it in its downward position
indicating EXTERNAL SOURCE. If not present, unit is ready for connection to the
air source.
3.4
Connect the "house" air to the lower inlet, Figure 2 (3), of the "house" air adapter
utilizing
inch swage connectors. Admit the "house" air to the "house" air adapter
1/4
and open the shutoff valve, Figure 2 (3), so that the "house" air enters the pure air
generator and registers its pressure on the INPUT PRESSURE gauge, Figure 1 (6).
NOTE:
THE MINIMUM ACCEPTABLE PRESSURE FOR THE INPUT AIR IS 50-
PSIG AND THE MAXIMUM PERMISSIBLE PRESSURE IS 95-psig. Any
pressure lower than the minimum will compromise the effluent air purity
and any pressure greater than 95-psig will exceed the working capacity
of the inlet solenoid valves.
3.5
At this time, check for leaks using soap solution on all connecting fittings. Tighten
as required.
NOTE:
The horizontal shutoff valve, Figure 2 (3), at the base of the "house" air
adapter serves as a shutoff to the air supply so that the pure air
generator may be moved and, should the need arise, the filter element
may be changed without shutting off the main air supply.
