INSTALLATION
Hazardous voltage. Can shock, burn or kill.
Do not lift pump by the power cord. See “Cord Lift Warning”
on Page 3.
NOTICE:
Install the pump on a hard, level surface (cement,
asphalt, or inside a sump basin, etc.). Never place the pump
directly on earth, clay or gravel surfaces.
Piping
Piping must not be smaller than pump discharge.
When installed in a
sewage
system, the pipe must be capable
of handling semi-solids of at least
2"
(51mm) in diameter.
The rate of flow in the discharge pipe must keep any solids
present in suspension in the fluid. To meet minimum flow
requirements (2 feet per second in the discharge line), size
the pipe as follows:
A Pipe Size Of:
Will Handle a Flow Rate Of:
1-1/2" (38mm)
12 GPM
2" (51mm)
21 GPM
2-1/2"(64mm)
30 GPM
3"(76mm)
48 GPM
In a
sewage
system use a
2"
(51mm) check valve in pump
discharge to prevent backflow of liquid into sump basin. The
check valve should be a free flow valve that will easily pass
solids. Be sure check valve installation complies with local
codes.
NOTICE:
For best performance of check valve when han-
dling solids, do not install it with the discharge more than 45°
above the horizontal. Do not install the check valve in a verti-
cal position as solids may settle in the valve and prevent it
from opening on startup.
Drill a 3/16" (5mm) hole in the discharge pipe about 1–2"
(25-51mm) above the pump discharge connection (but below
check valve) to prevent airlocking the pump.
Electrical
Hazardous voltage. Can shock, burn, or kill.
When installing, operating, or servicing this pump, follow the
safety instructions listed below.
1.
DO NOT
splice the electrical power cord.
2.
DO NOT
allow the electrical cord plug to be submerged.
3.
DO NOT
use extension cords. They are a fire hazard and
can reduce voltage sufficiently to prevent pumping and/or
damage motor.
4.
DO NOT
handle or service the pump while it is connect-
ed to the power supply.
5.
DO NOT
remove the grounding prong from the plug or
modify the plug. To protect against electrical shock, the
power cord is a three-wire conductor and includes a
3-prong grounded plug. Plug the pump into a 3-wire,
grounded, grounding-type receptacle. Connect the pump
according to the NEC or CEC and local codes.
For automatic operation, plug or wire the pump into an auto-
matic float switch or duplex controller. The pump will run con-
tinuously when plugged directly into an electrical outlet.
Connect or wire pump to its own individual branch circuit with
no other outlets or equipment in the circuit. Size fuses or cir-
cuit breakers according to the “Motor, Switch and Cord
Specifications” chart.
Risk of electrical shock and fire. Be sure
that power supply information (Voltage/ Hertz/Phase) on
pump motor nameplate matches incoming power supply
exactly. Install pump according to all electrical codes
that apply.
Explosion hazard.
Improper ventilation of
sewer gases can result in leakage of methane sewer gas,
and a possible explosion of fumes, resulting in severe injury
or death. Vent basin according to all local codes.
NOTICE:
Proper ventilation is needed to prevent negative
basin pressure and to provide air for proper aerobic activity
within the basin.
The sewage basin should be located at the lowest place in the
basement or area to be drained. Floor drains from other areas
in the basement may be tiled into the basin. Drain tile around a
house foundation may also be tiled into the basin, effectively
removing water and relieving pressure from this area.
Basin covers are used to exclude refuse from the basin.
NOTICE:
Read and understand this instruction manual
before your concrete floor is poured.
Installation Instructions. See Figure 1.
1.
Dig the hole for the sewage basin and the sub-base. The
hole must be deep enough so the finished floor is flush
with the top of the basin. Refer to Figure 1, Page 3.
NOTICE:
The sub-base should include 4" of sand or
gravel. The maximum diameter of crushed rock should be
1/2". The recommended maximum diameter of pea gravel
is 3/4".
2.
Level the sub-base out, until it is smooth. Sharp rock can
damage the basin.
3.
Install the basin on top of the sub-base.
4.
Backfill around the basin with crushed rock, with a maxi-
mum diameter of 1/2", or use pea gravel.
5.
Insert the 4" inlet pipe through the rubber grommet. Insert
it 2 inches into the basin. Dish soap can be used to lubri-
cate the rubber grommet. If necessary, file the sharp
edges of the pipe to prevent damage to the grommet.
NOTICE:
The pipe should pitch down to the basin inlet at
1/4" per foot. This will cause the water to run into the
basin.
6.
Lubricate the square cut O-Rings with dish soap. Insert
them into the groove on the bottom side of the flanged
grommets.
7.
Install the flanged grommets into the basin lid.
8.
Install the discharge pipe into the 2" FNPT discharge
grommet.
