Installation and Maintenance Manual
The Cycle Valve is a unique device that allows a series of jets to pulsate in a predetermined pattern. The pattern or
layout of the jets is infinite and even the speed at which they pulsate is adjustable.
The Cycle Valve is also unique in that it is water powered. There is no special requirement for electric motors or unsafe
electrical wiring. The same water pump that powers the jets also powers the Cycle Valve.
The Cycle Valve has been designed for years of trouble free operation.
However, a few installation tips will insure your continued satisfaction.
The Cycle Valve should be installed so that it is only operating when desired by the user. Never install the Cycle Jet 1.
on a time clock or filter cycle operation.
When sizing your system for pump requirements, we recommend approximately 8 to 10 GPM at 15 PSI for the 2.
motor end and 28 to 35 GPM at 15-18 PSI for the output housing or jet operation. NEVER exceed 20 PSI for the
motor or output housing as it may cause damage to the Cycle Valve.
The Cycle Valve is designed to operate with jet orifice openings of 7/16” diameter, but can also operate on jets 3.
with 1/4” orifice size. When operating two jets per outlet, a smaller orifice size should be used. Always consider
the orifice sizes when planning your installation and pump requirements. Do not use flow adjustable jets for the
Cycle Valve . If the flow of water is interrupted by use of flow adjustable jets, a pressure spike could occur and
cause damage to the Cycle Valve.
When installing the Cycle Valve for the first time, the spa or whirlpool manufacturer should install the unit as shown 4.
in the diagram marked “OEM FIRST TIME INSTALLATION”. By using the valves and pressure gauges shown in the
diagram, you can balance the system, evaluate and optimize the pressure of the massage delivered by the Jets as
well as the duration and frequency of the massage delivered by the jets.
NOTE: Production installation will not require the valves and pressure gauges shown in the “OEM FIRST TIME
INSTALLATION,” but may require the use of a bypass valve or additional jets.
Once the level of performance and the system have been optimized, a standardized installation method can be
used. Some standard installation methods are described below and shown in the accompanying diagrams.
The Cycle Valve can be installed using several different options:
A. When using the Cycle Valve with larger pumps or in conjunction with other jets or options, it can be installed
using a 3 way valve to divert flow to and from another bank of jets or other option. (See the diagram labeled
“CYCLE VALVE INSTALLATION USING A 3 WAY VALVE”.)
B. It can be installed on a pump designated solely for the Cycle Valve. The Cycle Valve will run very efficiently
using a 1.0 HP Pump designated specifically for the Cycle Valve. See the diagram labeled “CYCLE VALVE
INSTALLATION USING BOOSTER PUMP”.
C. When using a larger pump with a 3 way valve, it may be necessary to use a Bypass Valve to prevent applying
too much pressure to the Cycle Valve. NEVER exceed 20 PSI to the motor or to the output housing of he Cycle
Valve. See the diagram labeled “CYCLE VALVE INSTALLATION USING 3 WAY VALVE WITH BYPASS”.
