INSTALLATION INSTRUCTIONS
CONTROL PANEL
. Select a mounting location away from direct contact with water and oil. Dry locations in the
bathroom, salon, or galley are most desirable.
2. Confirm clearances for the panel behind walls, hull liner or bulkhead.
3. Cut out mounting hole for control panel. (See template for cut-out and hole locations.)
4. Do not mount the control panel until wiring is routed and secured to the terminal block or
rear of the control panel housing.
5. Route wiring following the wiring diagram for blackwater or graywater applications.
PLEASE NOTE: remove jumper wire between pins 4 and 5 if the optional seacock interlock
switch is installed.
6. Include wiring for any of the optional electrical accessories that may be part of the installation
and shown in separate wiring diagrams.
7. Mount the control panel with the (4) #6 x -inch long black, oval-head screws provided.
8. Insert the correct color lens in the appropriate hole from the front side of the faceplate,
snapping the matching light into the lens firmly. Color coding is as follows:
a) Green: Discharge Pump On
b) Yellow: Check Seacock (optional)
9. Tuck the lead wires back into the housing so that the tension is taken off the switch in order
to allow the key to be turned freely. Insert the two (2) small tabs on the left side of the faceplate
into the housing, and snap the large center tab on the right of the faceplate into the housing to secure it.
0. NOTE: The TankMaster
® 4 comes with the lead wires (with female terminals from the
circuit board) attached to the keylock switch numbered tabs as follows:
a) Terminal 1: Red
b) Terminal 2: Brown
c) Terminal 7: Blue
d) Terminal 8: Red
fLOAT SWITCH ADJUSTMENT
1. It is important that the low- and mid-floats of the TankWatch ® 4 level indicator cap are adjusted
for the TankMaster™ to operate properly.
2. The #1 float must be positioned just slightly above the diptube opening or tank outlet. If this float
is positioned too low, the discharge pump will not shut off properly. This is because the low
float will never disengage due to the pump unable to discharge the sewage that is below the tank outlet.
3. The location of the #2 float is entirely up to the installer. The higher the float is positioned, the
longer the discharge pump cycle will be. We recommend locating the float approximately
4 inches above the #1 float.
4. If either a longer or shorter pump cycle time is preferred, adjust the #2 float accordingly.
However, when the floats are also used for the TankWatch 4, the empty, low and mid readings
may not be true after adjustment. For example, if the #2 float switch is raised several inches
in order to obtain a longer pump cycle time, the mid light on the TankWatch 4 will actually
signal that the tank is slightly fuller.
