STAR Water Systems HomeGuard OPTIMA Manual Del Usuario página 3

The Home Guard Optima pump can be installed very easily as a standby to an electric sump pump (see
®
sketches). However, a check valve is required between the electric pump and the Home Guard
Note 1: Per the Uniform Plumbing Code and the Plumbing Codes of some states, installation of this product
requires the use of a RPZ backflow protection device. Contact your local plumbing or water authority for more
information regarding the requirements for your specific area.
Note 2: Per the Uniform Plumbing Codes and IAPMO PS119, the discharge of the water-powered sump pump should
not be connected to the discharge of the primary sump pump.
STEP 1: Placement of the Pump in the Pit
Note: If your pit has a cover, it will have to be modified to accommodate the Home Guard
1.1) Inspect the pit for debris and clean as necessary.
1.2) Place the pump in the pit, making certain that the inlet fitting of the pump is at least 6" above the basement floor
or top of the sump pit. Ensure the pump is clamped securely to the primary pump discharge pipe. Mark the
location on the discharge pipe.
This pump is to be used as a backup to your primary pump. Make certain that there is no interference
between the two pumps, especially between the float systems.
STEP 2: Float Stop Adjustment
2.1) With the Home Guard
inches above the ON level of the existing pump). The pump turns on at a water level of 2" to 3" below the upper
float stop, depending on the incoming water pressure. Calculate the appropriate float stop location based on
this distance.
2.2) The OFF level is determined by the buoyancy of the float as well as the incoming water pressure, roughly 6" to
8" below the ON level. The OFF level must be above the suction screen of the foot valve. Adjusting the lower
float stop will not change the OFF level of the pump. It is recommended to install the lower stop tight to the
bottom of the float so that it cannot move on the float rod.
2.3) Remove the pump from the pit and adjust the float stops as necessary. Tighten all screws. Be sure to tighten
the lower stop properly so that it will not come off. If the lower stop comes off, the float will drop off the float rod,
rendering the pump non-operational and possibly damaging the pump.
2.4) Replace the pump in the pit at the same location on the primary pump discharge pipe as marked earlier (Step
1.2). This will ensure that the ON and OFF levels are consistent with the calculations.
STEP 3: Installation of the Discharge Piping
3.1) Glue the discharge pipe into the pump as shown in the figure below (reference SK2721B).
3.2) Per the Uniform Plumbing Codes and IAPMO PS119, the discharge of the water-powered sump pump should
not be connected to the discharge of the primary sump pump.
3.3) In order for this installation to work properly, a check valve must be installed onto the discharge line. The
following Star Water Systems check valves are recommended: KH34 and KH81. Some local codes require a
union check with ball valve.
STEP 4: Installation of the Source Water Piping
4.1) Shut off the municipal water supply and plumb the tubing/piping into the municipal water supply line. This must
be branched off of a ¾" line and plumbed with ¾" tubing/piping to the Home Guard
hose or other flexible hose/tubing. Install a shut off valve in the ¾" supply line to the Home Guard
the appropriate back-flow prevention for your jurisdiction.
