TEST OR INSPECTION
CORRECTIVE ACTION
Step 9. Check separators. (MODEL WTrA60 ONLY) I
(Normal waste flow is about 1-2 gpm (4-8 Ipm) when the high pressure pump is running.) If little or no flow
comes out of the waste flow hoses when the high pressure pump is running, recheck height of pump above
water level, distance to the ROWPU van, and height of van above pump. If any distance is greater than
limits, reposition equipment accordingly. Check that separator waste hoses are not plugged with sand or
dirt. Notify unit maintenance that raw water pump should be tested for correct operation.
CAUTION
Operation can continue by removing the separators and pumping direct to the van. If operating at a beach
site with surf and sand or if operating at site with a lot of seaweed and organic debris, the in-line strainer
will plug frequently. Do not overstress the ROWPU electrical gear by starting and stopping too often.
If there is a heavy stream of water coming from the separator waste hoses, check for plugged, collapsed
hoses or blockage in the piping.
Step 9. 1. Check Separator (MODEL ROWPu-1 ONLY)
NOTE
(Normal waste flow is about 14-15 gpm (51.8-55.5 Ipm) when the high pressure pump is running.
If little or no flow comes out of the waste flow hose when the high pressure pump is running, recheck
height of pump above water level, distance to the ROWPU van, and height of van above pump. If any
distance is greater than limits, reposition equipment accordingly. Check that separator waste hose is not
plugged with sand or dirt. Tap the bottom of the separator to loosen any clogging debris.
If there is a heavy stream of water coming from the separator waste hoses, check for plugged or
collapsed hoses or blockage in the piping.
CAUTION
If operation at a beach site with surf and sand or if operating at a site with a lot of seaweed or organic
debris, the In-line basket strainers will be need to be cleaned more often.
Step 10. Notify unit maintenance.
15. Raw water pump heat lamp does not work.
NOTE
Heat lamp only works when raw water pump is off.
Step 1. Check SUMP HEAT/PUMP HEAT OFF/ON switch on main control panel.
Turn ON.
WARNING
Position SUMP HEAT/PUMP HEAT OFF/ON switch to OFF before proceeding. Failure to do so could
result in electrocution.
Step 2. Check heat bulb.
Replace if broken or burned out.
