Selecting the Proper Location for this Device.

You should mount this device on one of the pipes that are returning the water to the spa, after it has been filtered and heated. If possible, place this device on the main return line that feeds all jets, preferred, but usually not possible.

This single GMX Model 848 device will take up about 5" to 6" of pipe space.

Additional Considerations:

• This location MUST be at least 6" downstream of (after) your spa heater.

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

1. Place the GMX Model 848 device against the pipe to be treated.

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. You are finished with the installation.

Spa Stabilization After Installation

After installation, run your spa continuously for the first five to seven days to remove the scale build-up from the heater and other surfaces. You must THEN drain and refill to the proper level and run for at least twenty-four more hours. This will purge the excess minerals from the spa water.

In many circumstances, no chemicals are required to maintain crystal clear water with no scale build-up as long as the pump is run at least two hours per day.

Installation Instructions are Shipped with Each System.
