Tank Switch Installation and Operation:

There are two sets of terminals on the MPC-5000 PCB that can be used in four different con- figurations to automatically start and stop the watermaker, or to automatically stop the water- maker when the tank(s) are full without the auto start feature. These terminals are on the green ten pin connector and are labeled “Float Switch 1” and “Float Switch 2.” Float Switch 1 is the tank full switch and Float Switch 2 is the tank empty switch.

If the unit is wired for both Autostart and Autostop, it can be put into AutoFill Mode by push- ing and holding the Auto Run switch on the MPC-5000 display. In this mode the watermaker will start whenever the water level drops below the tank empty switch, so that it is open (not conducting electricity). When the tank fills up and both the tank full switch and the tank empty switch have remained closed for two minutes, the watermaker will shut down and flush itself. The watermaker will start back up when the water level drops below the tank empty switch and it remains open for 2 minutes. This configuration allows for completely automatic operation. If the watermaker does not need to start up within five days it will automatically do a fresh water flush. AutoFill mode can be ended by pushing the stop button or the Autoflush button. If the watermaker is in Autorun mode it can be put into Autofill mode without stop- ping it by holding down the Autorun button.

If the owner prefers to install the automatic shutoff feature without the automatic start up op- tion, only the tank full switch is used. A jumper must be placed between the tank empty ter- minals (Float Switch 2) in place of the tank empty switch, because the watermaker will only shut down if both sets of terminals are closed. To use this mode the watermaker must be started up with the Stop/Start button or the Autorun button. After the unit starts up, then press and hold the Autorun button until the display reads “Auto Fill Mode”. The watermaker will fill the tank and automatically enter Autoflush mode.

It is possible to use the autofill feature with 2 tanks. A double throw electrical switch must be installed in a convenient location. If only the single tank full switch is installed in each tank, connect the wire from Float Switch 1 terminal “1” to the common on the switch and run sepa- rate wires from the switch to each tank switch. The second wires can both be run to the Float Switch 1 terminal 2. If you are using two switches in each tank, you will need a double pole double throw switch.

Note: If the Automatic startup is enabled the watermaker may start at any time. Because no one may be available to check for oil in the water around the boat, it is recommended that an oil-water separator, part number FT-FTC-OW be installed in place of the 20 micron filter.
