MALFUNCTION
TEST OR INSPECTION
CORRECTIVE ACTION
ROWPU ASSEMBLY.
1.
ROWPU leaks oil.
(a)
If air compressor assembly leaks oil, notify direct support maintenance.
(b)
If high pressure pump assembly leaks oil, notify direct support maintenance,
2.
ROWPU leaks air.
WARNING
Make certain COMPRESSOR ON/OFF switch is turned OFF and the bleed valve at the side of the
compressor has been opened to relieve pressure before changing outlet filter or working on compressor.
Serious injury could result if this is not done.
NOTE
Use soapy water to detect leaks.
NOTE
The air compressor is a low volume high pressure air compressor. It does not take a big air leak to cause
air system problems. Find and repair all leaks for best performance.
Isolate air leaks.
(a)
If low pressure air manifolds leak, replace manifold (para. 4-68).
(b)
If low pressure air valve leaks, replace valve (para. 4-68).
(c)
If low pressure air tubing fittings or tubing leaks, repair (para. 4-24).
(d)
Replace tubing that leaks, tighten fittings (para. 4-24).
(e)
If high pressure air pipe line tubing, fittings, or piping leaks, notify direct support maintenance.
(f)
If high pressure air regulator leaks, notify direct support maintenance.
(g)
If air compressor relief valves leak, notify direct support maintenance.
(h)
If air dryer leaks, replace air dryer (para. 4-67).
(i)
If low pressure air solenoid valves leak, repair or replace (para. 4-51).
(j)
If high pressure solenoid valve leaks, notify direct support maintenance.
(k)
If high pressure relief valve leaks, notify direct support maintenance.
(I)
If high pressure switch leaks, notify direct support maintenance.
(m)
If air reservoir tank or shutoff valve leaks, notify direct support maintenance.
(n)
If low pressure air relief valve leaks, notify direct support maintenance.
(o)
If outlet air filter assembly leaks, notify direct support maintenance.
(p)
If air compressor assembly leaks, notify direct support maintenance.
(q)
If turbidity panel air system leaks, repair leaking components (paras. 4-50 and 4-58). (MODEL WTA-
060 ONLY)
(r)
If automatic valves leak at side vent fittings, replace the appropriate air solenoid valves (para.4-47).
3.
ROWPU control panel will not power up.
Step 1.
Check connections between generator and ROWPU.
Tighten loose connections.
Step 2.
Check that generator voltage is 440 VAC on all three phases.
(a)
If voltage is not present on all phases, refer to generator maintenance manual TM 5-61 15-545-12.
(b)
If voltage is present, the generator control panel is properly set up, and the control panel is properly
set up, notify direct support maintenance.
