Cut main supply line as required to fit hydrocharger in plumbing between well
pump and pressure tank (hydrocharger may be installed in a vertical or
horizontal position). Allow a minimum of 6 inches straight run of pipe on each
side of hydrocharger, excluding fittings. Be certain direction of flow arrow on
hydrocharger points toward pressure tank, and pressure control switch is located
on pressure tank side of the hydrocharger as in Fig. 1, 2 or 3, (rapid cycling of
pump may occur if pressure switch is located on well side. If check valves are
used, they should be installed before the hydrocharger – not between the
hydrocharger and pressure tank).
NOTE: It is advisable to install the hydrocharger with the unions at both ends to
facilitate removal and inspection. If heat is applied near hydrocharger, remove
rubber check valve to prevent damaging it. On badly scaled, older pumping
systems, it may be advantageous to install an optional "Y"-strainer ahead of
hydrocharger to prevent plugging hydrocharger nozzle with scale.
3.
Cut main supply line as required to fit plumbing to control valve and attach the
bypass valve (Figure 5).
4.
Solder or solvent weld plumbing. Do not apply heat to any fitting connected to
control valve as damage may result to internal parts. Check to be certain water
supply pipe is connected to control valve inlet fitting, and pipe connected to
control valve outlet fitting is in direction of house service (see Figure 6).
NOTE: If the installation is to be split-streamed prior to the filter tank (Figure 2)
or is a public water supply type installation (Figure 3), refer to special
instructions on Page 7.
5.
Loosen set screw and pull out drain line flow control assembly from valve body.
Unscrew drain line fitting elbow from drain line flow control. Apply pipe dope or
teflon tape to threads. Reassemble to valve body, making certain drain line flow
control assembly is fully inserted into valve body before tightening set screw.
Attach 1/2 inch ID drain line to drain elbow. CAUTION: Set-screw requires only
finger pressure to hold plastic flow control in place. Over-tightening set-screw
may crack fitting.
6.
Position drain hose over drain and secure firmly. To prevent back-siphoning of
sewer water, provide an air gap to code or equivalent. (Figure 6) Do not raise
drain hose more than 10 ft. above floor.
7.
Loosen the two screws on the timer cover to remove it from the timer.
CAUTION: This timer's programs will be out of sync if you turn the knob too far
or do not allow the drive motor to stop completely before continuing to the next
step. If this happens while doing any procedure rotate the knob clockwise until
the white dot lines up with the time of day arrow and the unit will return to the
service position. You can then start again.
8.
Turn on power to well pump. The DUROclean IF is supplied from the factory in
the backwash position ready for start up. Turn the water supply on to the unit.
Open the supply line slowly and allow the air to escape from the filter before
turning the supply water on all the way. Allow the unit to backwash until all the
air and media fines are no longer showing at the drain. This procedure may take
several minutes so do not supply power to the timer until this procedure is
complete.
During initial backwashings, a small amount of fine white media may be
observed in the drain water. This is normal. Now supply power to timer and
allow the unit to finish the cycle on its own.
9.
Set hydrocharger by following these steps:
A. Open nearest faucet until pump starts, then close faucet.
B. Place a finger over suction port (Figure 7). A slight suction should be detected for a minimum of 20 seconds or for
approximately one-third of pumping cycle whichever is greater.
C. If suction duration is too short, increase by turning water flow adjusting screw (Figure 7) clockwise. To decrease
duration, turn counterclockwise.
D. Repeat Steps A through C until proper setting is obtained. When the duration of the suction is too long, cold water
may have a "milky" appearance caused by excess air in system. Correct this condition by reducing the duration of
suction. This condition is one commonly associated with bladder-type pressure tanks. In extreme cases excess air
prevents the system from performing satisfactorily, consequently it is essential to install an air relief valve (such as
Braukman) in the proper location.
10. Make certain bypass is closed and inlet and outlet valves are fully opened. Check for leaks.
11. Set time-of-day and backwash frequency (see Page 10, Programming Backwash Controls).
NOTE: After start-up, this filter may take several days to completely remove the iron. This is normal because of the
nature of the media.
