1.
Valve off any pressure going to the “INPUT PRESSURE” port. Disconnect the
supply gas if desired. Alternately, the Regulator Pressure knob can be adjusted until
the regulator pressure reads zero.
2.
With the input pressure shut off, slowly vent the output pressure by cracking the
output connector to let the pressure slowly release or by continually cycling the
controller between an acceptable control pressure and vent until pressure is drained.
Maintain a safe noise level when venting. Wait until the output gauge reads 0 psi
before disconnecting the controller or load.
TROUBLESHOOTING
This section provides simple operational checks. The Haskel AAD-5 manual attached
contains additional information.
If the unit does not pump…
1.
Verify that the “INPUT PRESSURE” has pressure applied.
2.
Verify that the regulator pressure knob is slightly open and the Regulator Pressure
gauge reads approximately 50 to 150 psi (just not at zero).
If the unit continually cycles after reaching pressure and the temperature of the gas has
stabilized or when cycling occurs when not being used….
1.
Check for leaks in the system. Use a leak detector to track down and correct the
problem.
MAINTENANCE
NOTE:
High Pressure Gas can be dangerous. Maintenance of this unit
should be performed by fully qualified personnel only.
Booster Unit:
The control valve and the pilot valves on the Haskel Booster may occasionally need re-
lubrication on units experiencing a high amount of use. Instructions and a special lubricant
are provided in the Haskel manuals in the Appendix.
Drive Pressure Filters
Each booster is equipped with a filter and regulator. The filters should be inspected on a
regular basis. Drain any accumulated moisture or sludge through the drain petcock on the base
of the filter.
Occasionally, clean the internal filter element inside the filter sediment bowl. To access the
element, first disconnect all pressures from the system. Unscrew the filter bowl ring nut by
hand and remove the bowl and filter element screw.
