Eco Master Installation For Ozone Ready Spas
The instructions contained in this manual will help ensure a successful installation. It is the installer’s responsibility to make sure
these guidelines are followed.

The Eco Master System is designed to operate on either 120 or 240 VAC, 50/60 Hz. Wire system to the circulation
pump or timer. The Eco Master and circulation pump should start simultaneously. Use N.E.C or local code
grounding and installation procedures for spa equipment.

MOUNTING
It is recommended that the Eco Master be mounted as high as possible, to relieve the pressure on the check
valve. The recommended mounting orientation of the Eco Master is on a vertical surface. The Eco-Master should
never be mounted with the inlet and outlet ttings in a vertical orientation. The ¾” ttings should be horizontal
and level.
The above diagram shows that a dedicated return line for the Eco Master is recommended to limit back
pressure on the system, typically in the footwell or at the lter cavity. Alternatively, if the system cannot be
plumbed to a dedicated return, then the system should return as the last component on an unrestricted line.
The Eco Master requires between 3-10 GPM of water ow for optimum performance. This is accomplished by
installing the Eco Master at a location in the water circulation system, where the pressure at the supply line (P1)
is higher than the back pressure on the system at the return line (P2). Install the Injector prior to the EcoMaster,
as close as possible to the unit. If there is not enough pressure dierence between these two points, then you
will not see bubbles owing in the line at the output of the system. These bubbles are the main indicator of a
proper installation. In addition, consideration should be made for backpressure surges on the return line, as
back pressure may result in temporary leakage from the internal check valve. The back pressure on the
system at the return line should not exceed 10 PSI. The Ozone Line and Check Valve must be connected from
the 1/4” Hose Barb on the EcoMaster to the #1 port on the Injector. This line should include at least one full
loop and be secured as high as possible under the skirt, above the water level if possible.
