4. Unscrew the Nut (#15) on the end of the cylinder and remove the Piston, Shaft, and
Handle Assembly (#1) from the Tester.
5. Drain all the liquid from the Piston, Shaft, and Handle Assembly (#1) and from the
Manifold and Sleeve Assembly (#2), in the plastic container.
6. Remove the Tester from the large plastic container.
7. Carefully remove the O-rings from the Piston, Shaft, and Handle Assembly (#1) to
avoid scratching the Piston. Rinse the O-rings in hot running water and blow dry.
CAUTION:
DO NOT USE ALCOHOL TO CLEAN O-RINGS.
8. Rinse all metal parts in a solvent such as mineral spirits or naphtha. Then, rinse in
hot running water.
Note:
While cleaning and drying the Tester, turn the Selector Valve (#9) alternately
between the Reservoir (#3) and the Outlet Fitting (#18) positions.
9. Drain all the water. Then, rinse in alcohol and blow dry.
CAUTION:
DO NOT USE WOOD ALCOHOL.
10. Install the O-rings (cleaned and dried in step 3.3.A.7) on the Piston, Shaft, and
Handle Assembly (#1).
11. Using the large Nut (#15), assemble the Piston, Shaft, and Handle Assembly (#1)
together with the Manifold and Sleeve Assembly (#2). To do this, lubricate the
Threaded Shaft (#1) with commercial Vaseline, and the O-rings with silicon grease
(refer to section
12. Install the Master Gauge on the Adapter (#14) using Teflon tape.
13. Refer to section
to fill the Tester with the new
fluid.
4. OPERATION PROCEDURES
A. After completing all steps listed in section
with the appropriate hose or tubing, the Tester Outlet Fitting (#18, not included) to the
unit or system to be tested. The size of the outlet port of the Selector Valve (#9) is 1/8”
NPT. Then, perform the following steps.
CAUTION:
ENSURE MAXIMUM WORKING PRESSURE FOR TESTER (600 psig) OR
MASTER GAUGE (WHICHEVER IS LOWEST) IS NOT EXCEEDED
DURING TEST.
Note:
Refer to Figure 6 to identify item numbers.
1. While observing the Master Gauge and the system or unit-under-test, and with the
Selector Valve arrow (#9) pointing toward the Outlet Fitting (#18), rotate slowly the
Screw Handle (#1) clockwise (CW), until reaching the desired testing pressure.
Lightly tap the Master Gauge when taking test readings.
Note:
When connected to units or systems with long lines, the Shaft Screw (#1) may
reach the fully CW position, before the target testing pressure is achieved. If
this happens, perform steps 3.4.A.2-3.4.A.9, and then continue with the rest of
the test. If this situation does not happen, skip those steps, and proceed
directly to step 3.4.A.10.
2. Turn the Selector Valve arrow (#9) to point toward the Reservoir (#3).
