Flomatic CYCLE GARD I C152E Installation Instructions

Cycle Gard® I
Model C152E ½" thru1-¼"
NOTICE: Annual inspection and maintenance is required of all plumbing system
components. To ensure proper performance and maximum life, this product
must be subject to regular inspection, testing and cleaning.
Regulators in series: Where the desired pressure reduction is more then a 4 to 1
ratio (i.e.. 200psi to 50psi), multiple regulators in series should be installed.
DIAPHRAGM WARNING: Loosen jamb nut and adjustment screw slowly. Look
for any trapped water pressure under the diaphragm. Relieve pressure before
removing cover.
CAUTION: Anytime a reducing valve is adjusted, a pressure gauge must be used
downstream to verify correct pressure setting. To properly adjust the
downstream pressure there needs to be flow through the valve in the direction of
the flow arrow on the body. Do not bottom out adjustment screw on cover.
Valve may be installed in any position.
NOTE: Motor manufacturers recommend using a flow sleeve to be sure the
motor is properly cooled at low flow rates. Do not exceed 125 psi pressure
differential across the valve.
INSTALLATION INSTRUCTIONS:
1. Before installing reducing valve, flush out line to remove loose dirt and scale which might damage disc and seat and
turn power off. Install valve in line with arrow on valve body pointing in direction of flow. If the valve is equipped with (2)
union ends if only one is required, install the union end on the downstream side regulated pressure side of valve.
2. Install the valve downstream of the
pump and before the pressure switch
and tank. Note: If there are any
water outlets such as yard hydrant
of supply between the pump and
Cycle Gard ® I install a by-pass with
a check valve around the valve.
Warning- This pressure will be
unregulated pressure. Not
recommended for high capacity and
pressure pumps. The check valve
shall be installed with flow going in
the opposite direction of the Cycle
Gard® I. this allows for free flow
around the Cycle Gard® I unit to
provide tank pressure to the yard
hydrant or outlet (see illustration).
3. Pre-charge pressure in the tank should be 5 to 10 psi lower than pressure switch turn on pressure. All valves are
factory pre-set to 50 psi. To re-adjust reduced pressure loosen outer jam nut and turn adjustment screw clockwise (into
cover) to increase downstream pressure, or turn counterclockwise (out of cover) to lower downstream pressure. Valve
may be installed in the horizontal or vertical position. Open a line downstream and allow pump to turn on, then slowly
close supply valve downstream until demand is roughly around 2 to 3 GPM. Then adjust the valve until the downstream
pressure is constant, at about 10 psi lower then the cut off pressure of the pressure switch setting. Close off
downstream valve and the pressure tank will fill up at about 1 GPM at 50 PSI differential, 1.5 GPM at 100 PSI differential
for the 1" and 1-1/4" only.
Note: In systems using a small tank with 5 gallons or less of drawdown, adjust the regulated downstream valve
pressure to the same as the cut in (pump on) pressure setting of the pressure switch. For example if your system is
using a 40/60 pressure switch setting set your regulated downstream valve pressure at 40 psi. For longer run rimes set
your regulated pressure closer to the cut on (pump on) pressure setting on the pressure switch.
