STEP 4: (Continued)
4.2) Do not braze/solder copper fi ttings within 18” of Home Guard
®
Max, as the heat from the torch will damage the
pump body.
4.3) When assembling threaded fi ttings into the Home Guard
®
Max inlet, do not use pipe dope on the inlet threads,
use PTFE (Tefl on
®
) sealing tape. Take special care to keep any debris (including pieces of tape) from entering
the inlet fi tting that might get caught in the operating valve.
4.4) The Home Guard
®
Max includes a fi eld installed Push-to-Connect fi tting. This fi tting is designed to be used with
¾” PEX, CPVC, or copper pipe. The fi tting must be installed on the ¾" NPT thread of the pump inlet fi tting.
Caution must be used when installing the fi tting to not over tighten the inlet fi tting and crack the body. Using a
backup wrench, hold the inlet fi tting while tightening the Push-to-Connect fi tting. If the Push-to-Connect fi tting
is not used, the same precaution must be used when installing any other fi tting to the inlet fi tting.
4.5) Purge the water line prior to connecting to the Home Guard
®
Max to ensure that debris does not enter the unit
and clog the operating valve.
4.6) If using the Push-to-Connect fi tting, cut the tube so that the ends are square. Ensure that there are no burrs or
damage to the cut end. Once the tubing end is cut square and clean, scribe a depth mark on the outside of the
tubing 1” from the end. Insert the tube through the release collar to rest against the grab ring. Push the tube
fi rmly with a slight twisting action until it reaches the tube stop. The depth mark should be up to the end of the
release collar. The tube liner is not necessary with CPVC or Copper tubing, and may be removed based on
preference or local codes. The tube liner can be easily removed by pulling it out with a needle nosed pliers.
4.7) Once the pump has been installed and the municipal water source connected, open the municipal water source
valve and the supply line valve. Inspect the valve body and all connections looking for leaks. Close the
municipal water valve and fi x any leaks before operating the pump.
STEP 5: Testing of Pump Operation
5.1) Unplug the primary pump so that it does not start.
5.2) Fill the sump with water until the Home Guard
®
Max starts.
5.3) Verify that the pump starts and stops at the desired ON/OFF points.
5.4) Verify that there are no leaks in the discharge line.
5.5) If adjustment is necessary, raise or lower the stops according to STEP 2.
5.6) If the pump is not operating properly after following the above steps, refer to the Troubleshooting guide.
5.7) When fi nished testing, plug primary pump back into AC receptacle.
5.8) Install and adjust alarm reed switch (optional) to desired level.
WATER PRESSURE:
20 PSI minimum with valve open.
80 PSI maximum with valve open.
100 PSI maximum with valve closed.
EFFICIENCY:
The pumping capacity increases with household water pressure and fl ow.
At an eight-foot static head and a supply pressure of 20 PSI at water supply inlet with water fl owing, it takes one (1)
gallon of supply water to remove one gallon from the sump. As the supply pressure increases with the static head
constant, less supply water is required.
