Step 1
Shut off all water at main supply. On a private well system, turn off power to pump and drain pressure tank. Make certain pressure is relieved from
complete system by opening nearest faucet to drain system.
CAUTION CAUTION
To reduce the risk associated with property damage due to water leakage:
• When water supply is shut off, shut off fuel or electric power to water heater.
Step 2
Cut main supply line as required to fi t Hydro-Charger in plumbing between well pump
and pressure tank (Hydro-Charger may be installed in a vertical or horizontal position).
The Hydro-Charger has been supplied with both 1” threaded and 1” barbed (insert)
fi ttings to allow for installation with various types of piping materials. When using the
threaded nipples, use thread tape only. When using barbed (insert) fi ttings, appropriate
pipe clamps must be used. Once installed, the quick release nipples allow the Hydro-
Charger to be rotated, so the air draw adjustment screw is accessible for adjustment
by a small bladed screwdriver. Allow at least 10 inches of straight run of 1” pipe on
both inlet and outlet side of the Hydro-Charger. Refer to Figure 2 for correct assembly.
The quick release nipples also acts as a union to facilitate the Hydro-Charger removal,
inspection and cleaning as needed. With an installation on PVC pipe and copper tub-
ing it may require the addition of a normal plumbing union to aid in removal from the
plumbing due to the rigidity of that type of material. Make certain the directional ar-
rows on the Hydro-Charger points toward the pressure tank and the pressure control
switch is located on the pressure tank side of Hydro-Charger as in Figure 1. Rapid
cycling of pump may occur if the pressure control switch is located on well side. If a
check valve is located between Hydro-Charger and pressure tank, it may prevent the
Hydro-Charger from performing properly. Relocate to well side of Hydro-Charger.
Step 3
Turn back on the power to the well pump and pressurize the water lines to allow for adjustment of the Hydro-Charger. Check for leaks and adjust as
necessary.
IMPORTANT NOTES IMPORTANT NOTES
• Do not apply heat near Hydro-Charger, as damage may occur. On badly scaled, older plumbing systems, it may be advantageous to install a WYE
Strainer to help prevent plugging of the Hydro-Charger nozzle with scale or debris. The use of a WYE Strainer must precede the Hydro-charger
on the inlet side by a minimum of 10”.
• If existing water system includes a captive-air type pressure tank (bladder) and it is desirable to install an additional air to water type with an air
release (not as a split steam type installation) install an air to water type pressure tank between the Hydro-Charger and the existing captive air
type pressure tank.
• Before proceeding with Hydro-Charger installed, re-verify adequate pumping rate pumping by following the procedure described in Section
2. After verifi cation of adequate fl ow, depressurize system as described previously.
• If installation is to be split streamed prior to fi lter vessel or is a public water supply see Figure 1, or refer to Special Instructions on page 3-5.
Step 4
Set Hydro-Charger by following these steps:
a) Open nearest faucet until well pump starts, then close faucet.
b) Place a fi nger lightly over the suction port (Figure 3). A slight suction should be de-
tected for approximately one third (1/3) of pumping cycle time. (Do not confuse with
one third (1/3) of pressure range).
c) If suction is too short, increase by turning air adjustment screw (Figure 3), clockwise.
To decrease duration, turn counterclockwise.
d) Repeat steps (a) through (c) until proper setting is obtained. The optimum cycle time
is 60 seconds or more, with an air draw of 20 seconds minimum.
IMPORTANT NOTE IMPORTANT NOTE
When the duration of the suction is too long, the cold water may have a milky appearance caused by excess air in the water system. Correct this condi-
tion by reducing the duration of suction. This condition is commonly associated with bladder type pressure tanks. In extreme cases where elimination
of excess air prevents system from performing satisfactorily, it may be necessary to install an air to water pressure tank with an air release valve.
