This GMX-2848 and Spa Water Conditioning System" is designed for in ground spas and pools without water features. If you have a pool with water features or a spa that shares the filtration system with the pool, then this system is NOT for you. Please go to our Pool and Spa Systems Page and select the correct GMX System for your pool and/or spa. If you are not sure, please contact us via telephone at (928) 978-0757 or via email   .

These Two (2) Devices are placed over the pipe that returns the water to the pool or spa.

The GMX devices easily clamp over the outside of your existing pipes. The is no need to cut the pipes. Complete instructions below.

Mount horizontally or vertically
on your existing pipe.

These GMX devices can be easily placed on the outside of CPVC, PEX, PVC, or any type of Copper, Rubber or Plastic pipe.

Selecting the Proper Location for These Two Devices.

You should mount these two devices on the pipe that directly returns the water to your pool or spa, after the return water valves. You can bury these devices underground, if needed. Do not place these devices on the pipe going directly to the aeration device.

These two GMX Model 848 devices take up a total of 12" of pipe space and there must be at least 3" of straight pipe (no elbows or Ts) before and after these two devices. This is to minimize the turbulence in the water as it flows through each device. You will need a minimum of 18" of straight pipe to install both devices on the pipe returning the water to your pool or spa.

Additional Considerations:

• This location MUST be at least 6" upstream or downstream of the pool or spa heater.

• This location MUST be at least 12" downstream of (after) the pool or spa filter.

• This location MUST be at least 24" downstream of (after) the pool or spa pump.

1. Place the first Model 848 device against the pipe to be treated. Take note of the orientation of the label or arrow on the device.

2. Place the backing plate on the opposite side of the pipe and align the holes with the device.

3. Insert the nylon bolts through the holes in the device and backing plate. Then secure with the nylon wing-nuts. These bolts can pass through the device and the backing plate in either direction.

4. Tighten the wing-nuts until the device is snug against the pipe. Do not over tighten!

5. The second Model 848 device should be mounted tandem (see picture above) to the first. They MUST be spaced exactly 1" apart (very important) and both devices MUST be on the same side of the pipe.
   
   The GMX devices should tend to oppose, not attract each other. The GMX labels on both devices should face the same direction. It makes no difference which way the labels or the arrows point as long as both are facing the same direction.

6. You are finished with the installation.
