Receiving & Installation
Receiving Inspection
Upon receiving the pump, it should be
inspected for damage or shortages.
If damage has occurred, file a claim
immediately with the company that
delivered the pump. If the manual is
removed from the packaging, do not
lose or misplace.
Storage
Any product that is stored for a period
longer than six (6) months from the
date of purchase should be bench
tested prior to installation. A bench
test consists of, checking the impeller
to assure it is free turning and a run
test to assure the motor (and switch
if provided) operate properly. Do not
pump out of liquid.
Location
IMPORTANT ! - A CLEARANCE
UNDER THE PUMP FOR
ENTRANCE OF SEWAGE SOLIDS
MUST BE A MINIMUM OF 3
INCHES TO A MAXIMUM OF 4.5
INCHES.
Submergence
The pump should always be operated in
the submerged condition. The minimum
sump liquid level should never be less than
above the pump’s volute (See Figure 1).
Installation
The sump or basin shall be sealed
and vented in accordance with local
plumbing codes.
This pump is designed to pump grinder
or wastewater, nonexplosive and
noncorrosive liquids and shall NOT
be installed in locations classifi ed as
hazardous in accordance with the
National Electrical Code (NEC) ANSI/
NFPA 70 or Canadian Electric Code (CEC).
The pump should never be installed in a
trench, ditch, or hole with a dirt bottom.
The legs will sink into the dirt and the
suction will become plugged.
Discharge Piping
Install discharge piping or hose assembly
to the pump. Discharge piping should be
as short as possible and sized no smaller
than the pump discharge.
Do not
reduce the discharge pipe size below
that which is provided on the pump.
Both a check valve and a shut-off valve
are recommended for each pump. The
check valve is used to prevent backflow
into the sump. The shut-off valve is used
to manually stop system flow during
pump servicing.
If discharge hose is used instead of a
moveable fi tting assembly, be sure the
discharge pipe has a 1/8” diameter hole
approx. 5” from end nearest volute and
oriented towards the pump body.
Control Panel
PFGPC series grinders
DO NOT
require
a control panel, but do require a level
control with a piggy back plug, see
“Electrical Connections”.
Electrical Connections
Turn circuit breaker off before
plugging or unplugging the
switch and/or pump.
Always rely upon a Certifi ed Electrician
for installation.
Piggy-Back Plug:
Plug the level control
plug into a 6-20R receptacle, then plug
the pump into the piggy-back plug (See
Figure 2). It is recommended that this
cicuit have a 30 AMP breaker. One cycle
of operation should be observed, so that
any potential problems can be corrected.
It is recommended that the level control
fl oat should be set to insure that the liquid
in the sump never drops below the top
of the motor housing. The level control
should have adequate clearance so it
cannot hang up in it’s swing and that
the pump is completely submerged
when the level control is in the “Off ”
mode.
