General Safety Information
(Continued)
11. This equipment is only for use on
115 volt (single phase) and is
equipped with an approved
3-conductor cord and 3-prong,
grounding-type plug.
To reduce risk of
electric shock, pull
plug before servicing. This pump has not
been investigated for use in swimming
pool areas. Pump is supplied with a
grounding conductor and grounding-
type attachment plug. Be sure it is
connected only to a properly grounded
grounding-type receptacle. Where a 2-
prong wall receptacle is encountered, it
must be replaced with a properly
grounded 3-prong receptacle installed in
accordance with codes and ordinances
that apply.
12. All wiring should be performed by
a qualified electrician.
13. Make certain power source
conforms to requirements of your
equipment.
14. Protect electrical cord from sharp
objects, hot surfaces, oil, and
chemicals. Avoid kinking cord.
Replace or repair damaged or worn
cords immediately.
15. Do not touch an operating motor.
Modern motors are designed to
operate at high temperatures.
Risk of electric
shock. If your
basement has water or moisture on the
floor, do not walk on wet area UNTIL
ALL POWER HAS BEEN TURNED OFF. If
shut-off box is in basement, call electric
company or hydro authority to shut-off
service to house, or call your local fire
department for instructions. Remove and
replace system. Failure to follow this
warning can result in fatal electrical
shock.
Risk of electric
shock. Do not
handle pump or pump motor with wet
hands or when standing on wet or damp
surface, or in water. Always disconnect
the pump and switch from the electrical
power source before doing any
maintenance.
16. Pump water only with this pump.
Installation
(SEE FIGURE 1)
The basin (system) should be located at
the lowest place possible relative to
the area to be drained.
NOTE:
Make sure that the inlet of the
sink tray system is lower than the
water to be pumped.
1. Install inlet pipe in opening as
shown. Use RTV sealants or Plasto-
Joint Stik* to seal threads. See
Figures 2, 3, and 4, Page 3, for
typical installation arrangements.
2. Install discharge plumbing. When
using rigid pipe, use plastic pipe.
Wrap thread with Teflon tape or
use Plasto-Joint Stik*. Screw pipe
into discharge fitting hand tight

turns.
NOTE:
Do not use ordinary pipe joint
compound on plastic pipe. Pipe joint
compound can attack plastics.
3. To reduce motor noise and
vibrations, a short length of rubber
hose ((1

") I.D., e.g. radiator hose)
can be connected into discharge
line near pump using suitable
clamps.
4. Install an in-line check valve to
prevent flow backwards through
pump when pump shuts off.
