Installation • Operation • Maintenance
Follow these guidelines for installation:
1. Provide properly sized pit (see Specifications) on
sewage tank. Minimum pump run time is two
minutes. For maximum pump life, three minutes
is recommended.
2. Make sure sump is free of string, cloth, nails, gravel,
etc., before installing pump.
3. Do not set pump directly on the bottom of sump pit
if it is not solid. Raise the pump by using bricks or
concrete blocks underneath it.
4. Do not remove ground pin from electrical plug.
5. Do not use an extension cord to operate this pump.
6. For proper automatic operation, make sure the pump
power cord is plugged into the piggyback receptacle
on the switch cord. Three phase models must be
properly connected to a suitable control panel.
Do not cut, crimp, or bend single phase switch
power cord. This may cause pump failure and
void warranty.
7. Use steel or plastic pipe for all connecting lines
between pump and sewer outlet.
NOTICE: Some city regulations do not
allow installing a pump with plastic pipe.
Check local regulations.
8. Use PTFE pipe thread sealant tape on pipe
connections. Do not use ordinary pipe joint
compound on plastic pipe or pump. Pipe joint
compound can attack plastics and damage pump.
9. In applications where the pump may sit idle for
months at a time, it is recommended that the
pump(s) be cycled every month to ensure the
pumping system is working properly when needed.
10. A check valve should be installed horizontally in the
discharge pipe.
11. The optional Hydromatic Q Alert is an audible
alarm system for high water conditions. It should be
installed in every sump for greater protection.
NOTICE: Q Alert is for indoor use only. Other
Q Alarm and control panels are available for
outdoor use. Contact your Hydromatic distributor
for applications.
12. Use pump partially or completely submerged for
pumping waterlike liquids. The pump will pump
solid materials up to 3/4" (spherical) in diameter.
Risk of fire. Do not pump flammable
liquids. Strong chemicals or salt water should not
be pumped without consulting your Hydromatic
distributor for proper seals and coatings.
Operation
NOTICE: Do not allow pump to run in a dry sump.
Doing so will void the warranty and may damage
the pump.
An automatic overload protector in the motor will
protect the motor from burning out due to overheating/
overloading. When the motor cools down, the overload
protector will automatically reset.
If overload trips frequently, check for the cause. It could
be a stuck impeller, wrong/low voltage, or electrical
failure in motor. If an electrical failure in the motor is
suspected, have it serviced by a competent repairman.
Maintenance
Read the following instructions carefully before replacing
any parts. Reasonable care and safe methods should be
practiced. Check local codes and requirements before
installation. Only a competent plumber/electrician
should make the installations.
Submerge pump in a disinfectant solution (dilute chlorine
bleach) for at least one hour before disassembling pump.
The following steps should be performed only by an
authorized service center.
NOTICE: Read all directions before replacing any
parts. Remove pump and switch from power source
before servicing.
The numbers in parentheses, such as "(3)" or "(16)", refer
to item numbers used on the Repair Parts diagram.
Checking power cord
To be sure wires are not burned off or broken in cord,
use ohmmeter for check. Set ohmmeter scale to R X 1
scale and check meter by putting both meter leads
together and adjusting the needle knob until meter reads
zero. If meter cannot be adjusted to zero, the batteries in
meter must be replaced.
NOTICE: Always reset meter to zero [0] when going to a
new scale before making any checks on motor.
Attach one meter lead to white cord wire and one meter
lead to black cord wire, then place a screwdriver blade
across terminals of plug. If cord is OK, meter needle
will go to zero and stay there. If meter needle does not
move, the cord has an open wire and the cord must
be replaced.
