A device to disconnect the AQUASWITCH from the
power supply is required. It is recommended that
this switch or circuit breaker be labeled as the
disconnection device for the AQUASWITCH.
1 . AQUASWITCH I MAIN INPUT POWER
WARNING: All AQUASWITCH I’s are factory set for
115 VAC. Before starting, ensure the input power
“115/230” selection is correct for your requirements.
Failure to do so is beyond the responsibility of the
Myron L Company. See section II.E.3. and figure
I I . E . 1 a n d I I . E . 2 .
NOTE: Some models may have either a 24 VAC or a
24 VDC input power requirement - check labels
c a r e f u l l y .
1. Verify that the main AC power source is turned "OFF" or
disconnected.
2. Using a standard slot screwdriver remove the two (2)
screws on the front panel.
3. Carefully wiggle the front panel to loosen the gasket and
pull gently toward you. Do not pull more than about 8
inches/20CM or you could damage the wiring harness.
4. Turn the front panel around so that the back side is
facing you and set aside for now.
5. Using the enclosure cutouts, install the proper wire and
watertight cable restraint (not provided) to comply with
local electrical codes.
6. Neatly connect wires to the AQUASWITCH I 's
connectors*, as shown in figures II.E.1.
*CAUTION: The input power connectors require only a small
screwdriver, or a pen to push on the release levers†. The release
levers may be broken or damaged if not pushed straight toward
the circuit board. DO NOT push the release levers sideways.
† Early versions have screw terminals.
