Operation; Troubleshooting - Water Ace R50VLT Owner's Manual

OPERATION

Risk of electric shock. Shock can burn or kill.
Disconnect the power from the unit. Do not handle a pump or
pump motor with wet hands or when standing on a wet or
damp surface, or in water. Failure to follow this warning can
result in fatal electrical shock.
1. The shaft seal depends on water for lubrication. Do not
operate pump unless it is submerged in the water as seal
may be damaged if allowed to run dry.
2. The motor is equipped with an automatic reset thermal
protector. If the temperature in the motor should rise
unduly, the switch will cut off all power before damage can
be done to the motor. When the motor has cooled suffi-
ciently, the switch will reset automatically and restart the
motor. If the protector trips repeatedly, the pump should
be removed and checked as to the cause of the the diffi-
culty. Low voltage, long extension cords, clogged impeller,
very low head or lift, etc., could cause cycling.
3. The pump will not remove all water. If a manually operated
pump is operating and suddenly no water comes out of the
discharge hose, shut off the unit immediately. The water
level is probably very low and the unit has broken its
prime.

TROUBLESHOOTING

Hazardous Voltage. Can shock, burn or kill. Disconnect power to pump before servicing.

Defective motor
The anti-airlock hole is plugged.
Runs continuously Plugged screen
Defective switch
Float obstruction
Automatic Float Switch
1. Fill sump with 12"-14" of water to check operation and
tightness of connections. During first automatic cycle, it
may take 30 seconds or more before pump is primed and
pumping. Pump will start when water is approximately 7"
above pump base.
2. Check stop position. Pump will stop when water is approx-
imately 2" above pump base.
3. If pump does not operate, check electrical service.
4. Float must be free to move up and down in sump. Make
sure there is no debris in sump and that the switch is clear
from the sump wall.
AIRLOCKS
When a pump airlocks, it runs but does not move any water.
An airlock will cause the pump to overheat and fail. This pump
has a built in anti-airlock hole. See the exploded view on the
repair parts page for the location of the hole. Leakage from
the anti-airlock hole is normal.
If you suspect an airlock, unplug the pump, clean out the
anti-airlock hole with a paper clip or a piece of wire, and
restart the pump.
