 DOWN-THE-WELL INSTALLATION:

Often it is desirable to provide chemical feed

near the intake of the well pump for

additional retention time and mixing of the

chemicals. An additional length of discharge

tubing will be required for this installation.

Secure the end of the discharge tubing to the

pump cylinder, drop pipe, or foot valve and

lower it into the well. An anti-siphon valve

must be installed on systems such as this

where the discharge is lower than the feeder

and the chemical storage tank.

Failure to install anti-siphon valve may

allow siphoning to occur.

 ANTI-SIPHON VALVE: (optional)

Under any installation condition where the

possibility of siphoning or suction may occur

on the discharge side of the pump, install an

anti-siphon valve on the discharge side of the

feeder. The anti-siphon valve is not part of

the standard package. This item can be furnished by your dealer at extra cost.

 PRESSURE RELIEF VALVE: (optional)

Series 100/150 chemical pumps are rated to pump against a line pressure up to

100 PSI (7 BAR). If the line pressure on an installation could fluctuate above 100

PSI (7 BAR), install a pressure relief valve on the discharge side of the pump

head. Once the pressure reaches a certain level, the pre-set relief valve will

return the solution being pumped back to the solution tank. This will prevent

motor burnout or diaphragm rupture. The relief valve is not part of the standard

package. This item can be furnished by your dealer at extra cost. Read relief

valve instructions carefully before installing.

 BLEED VALVE INSTALLATION: (optional)

NOTE: After disconnecting power to the pump and taking necessary safety

precautions regarding the chemical and system.

1. Remove the coupling nut and tubing from the discharge port of the pump.

2. Remove the valve housing from the discharge side of the pump head and

replace it with the .38inch valve housing from the kit (this step is not required

if the pump is already fitted for .38inch tubing.

3. Install the TFE gasket over the discharge fitting.

4. Install the bleed valve assembly over the discharge fitting and gasket.

5. Install the bypass tubing from the kit into the bypass port of the bleed valve

and hand-tighten the coupling nut. Bypass tubing should be connected to

return bypassed liquid back to the solution tank.

6. Install the discharge tubing into the discharge port of the bleed valve and hand tightens the coupling nut.
