Pool Chemicals - Pool chemicals can be corrosive to electronic circuitry. It is highly
recommended that the communicator is not installed adjacent to the pool chemicals storage area
or the dosing systems themselves.
Minimum Distance from Cellular Signal - The communicator must be installed such that the
antenna is able to be located in an area with sufficient cellular signal (from the carrier of the SIM
card). How to determine this will be explained in 3.2.
Note: The communicator box is IP 55 rated, but should still be prevented from water or chemical
exposure to increase the lifetime of operation. Ensure that the location does not compromise the
equipment. The antenna may not be extended, but the cable from the communicator to the
controller may be extended up to 100m (300 ft) to allow for cellular signal to be obtained and/or
for the communicator to be located away from water or chemical hazards.
Site Requirements and Installation
The HydroGuard communicator is wall mounted. It is advisable to install it where the pool
operator and technician can easily view.
Hardware Installation
The following procedure will determine the required location of the communicator in order to
receive cellular signal.
A SIM card from a cellular provider will need to be obtained. The SIM card will need to allow
for data transfer using GPRS and should have a minimum data plan of 10 MB/month. Blue I can
provide you with a list of approved cellular providers in your area.
1. Remove the cover from the Expert Pool Communicator. Figure 2 displays the main
components inside the expert pool communicator.
2. Lift the cover from the SIM card holder and place the SIM card into the holder with the
notch facing up and to the right.
3. Close the holder and slide to lock in place. The card will only fit one way so do not force
it. If there is resistance, check for proper card orientation.
4. Attach the antenna line to the threaded connection on the bottom of the communicator
5. Place the antenna in a location that is expected to receive strong consistent cellular signal.
Do not modify the antenna/wire or connection to allow for this; move the communicator
if necessary (see below for more information).
6. Plug in the power to the communicator into a 110V or 220V AC plug
