10. GRINDER PUMP STAND
ASSEMBLY:
Temporarily
rest each grinder pump on its
side. Using a block of wood
or similar object, prop up
the lower pump end to allow
installation of the pump stand.
Align the two legs of each
pump stand half with two of
the holes in the pump lower
end (Figure 5). Push the stand
legs into the pump lower end.
Using a mallet, ensure that
the stand legs bottom into the
mounting holes. Repeat for the
other stand half. Turn the pump
upright on the installed stand.
11. DEBRIS REMOVAL:
Prior to start-up test procedure,
the incoming sewer line
must be flushed to force all
miscellaneous debris into
the tank. Next, all liquid and
debris must be removed. Once
the tank is clean, install the
pump(s) and proceed with the
test.
12. INSTALL THE PUMP:
Lower the pump(s) into the
tank. Position the pump so
the pump’s discharge is on
the opposite side of the pump
relative to the discharge in
the tank. Position the pump
in the center of the tank.
Rotate to coil the discharge
hose and slide the adapter on
the discharge hose into the
receiver in the tank wall until
it seats. Push the white slider
down to open the discharge
valve. Refer to Figures 8–11
for slideface connection and
operation.
Hang power cable, breather
tubing with Equalizer, and
lifting rope to prevent them
from laying in sewage. The
Equalizer should be hung as
high as possible in the tank.
13. TEST PROCEDURE
The WH/WR48 Series
stations are provided with
the following alarm panel
arrangements to control station
operation:
Each alarm panel contains
a single-pole circuit breaker
to control station alarm level
functions (visual and audible
alarms). The alarm panel will
also contain one (simplex) or
two (duplex), circuit breakers
to control grinder pump power.
The pump circuit breaker(s) are
labeled “PUMP” in the alarm
panel.
For each grinder pump in the
station, perform the following
procedure to verify proper
installation and operation:
a) Make sure that the slide
face discharge valve(s) is
fully open for each pump
connection. This valve(s)
must not be closed when the
pump is operating. In some
installations, there may be a
valve, or valves, at the street
main that also must be in the
open position when the pump
is operating.
(Ignore all Trouble
indications, LEDs and/or
messages until the panel
is reset at the end of this
procedure.)
b) Fill the tank with
approximately 200 gallons of
water (approximately up to the
top of the grinder pump).
c) Turn on the appropriate
pump power and alarm circuit
breakers, for the grinder pump
being tested, in the alarm
panel. The grinder pump
and alarm should turn on
immediately.
d) Monitor the pump and
alarm to ensure they are
operating correctly.
The alarm will shut
off at a water level
of approximately
18” from the
bottom. The pump
will shut off at
a water level of
approximately 14” from the
bottom.
e) Turn off the pump power
and alarm circuit breakers for
the pump tested.
f) Repeat steps A through
E for the remaining grinder
pumps in the WH/WR48 Series
station.
g) Clear/Reset the alarm
panel:
Sentry and T260 panels:
Reset is not required.
Protect Panel: Turn pump
and alarm breakers off and
back on simultaneously.
Protect Plus Panels: Perform
a “cold start” from the Initialize
System menu. Any user setting
that were previously chosen
will not be reset.
h) If any Trouble or alarm
conditions are indicated after
the panel is reset, contact your
local service provider.
