PREINSTALLATION CHECKLIST
1.
Inspect your pump.
Occasionally, products are damaged during shipment. If the unit or any of the parts are damaged, contact
your dealer before using.
2.
Read all the installation instructions
regarding installing and start up before performing any of the work described within.
Retain for future reference.
SEE BELOW FOR LIST OF WARNINGS
1.
For your protection always disconnect the power supply
from its power source before handling the components of
your primary pump.
2. Sump water is non-potable. To reduce the risk of contamination
of the potable water supply, the Home Guard
®
Max must
be installed with a listed backflow device suitable for the
installation, in accordance with the local plumbing code,
such as a reduced pressure principle backflow preventer
(RP). Alternately, consult the local plumbing and health
codes or the authority having jurisdiction for guidance on
cross-connection and backflow protection requirements.
CAUTION
SEE BELOW FOR LIST OF CAUTIONS
CAUTION
Turbulence caused by high velocity incoming
water can negatively affect the on/off action of the float
mechanism. If this condition exists, the incoming water must
be baffled to avoid excessive turbulence.

REFER TO WARRANTY ON PAGE 2.
1. This pump is designed for handling clear water. Do not use in
septic tanks to pump effluent or sewage pits to pump sewage.
2. Repair and service of your backup system should be performed
by an authorized service station.
3. The installation of this backup pump requires the use of a
variable level float switch for operation. It is the responsibility
of the installing party, to ensure that the float switch will not
hang up on the pump apparatus or pit peculiarities and is
secured so the pump will turn “on” and “off”. It is recommended
that the pit be 18" in diameter or larger to accommodate both
a primary and a backup pump.
4. Check the installation of the primary and backup pump floats
to ensure that both move freely and are not being encroached
upon where the float cannot move. Adequate space between
the floats must be maintained.
5. The pump should be manually activated once a month by
lifting the float rod. Let the pump run for at least 15 seconds
to prevent the pump from building up calcium deposits and
debris, which could harm the pump.
