III. Installation
Electrical Wiring
The controller has an internal regulated power supply that will operate in the range of approximately 100 to
240 VAC on the incoming wiring. Output relay 2 is protected with a replaceable fuse. Relay output voltage
will equal the incoming line voltage.
Prewired units are supplied with a 16 AWG cable with a 3-wire grounded USA 120 volt plug for incoming power
and 18 AWG 3-wire grounded receptacle cords for all control relay outputs. Conduit units are supplied with
liquid tights and adaptors for easy hard wiring to supplied connector.
NOTES:
1.
Liquid tight fittings and some labeled signal leads are provided for signal (low voltage) connections,
such as water meter inputs.
Mounting Instructions
Select a mounting location that provides the operator easy access to the unit and plumbing in and out. The
location should be convenient to grounded electrical connections, with a convienient drain location for the
flush outlet.
Drain
The AFS-E-25 sensor has
been designed to mount
on non-metallic floor drain
grids. The probe tips should
be pointed down through
the grating. Mounting holes
in the sensor body can be
used to secure it to the grid.
CAUTION
1. There are live circuits inside the controller even when the power switch on the front panel is in
the OFF position. Never open the front panel without first disconnecting power from the outlet.
Prewired controllers are supplied with an 8 foot, 18 AWG power cord with USA style plug. A #1
Phillips driver is required to open the front panel.
2.
Low voltage signal wires (probes, flow switch, water meter, etc.) should never be run
in conduit with high voltage (like 115VAC) wires.
3.
Never attempt to land connections to the controller without first disconnecting power from the outlet.
4.
Do not block access to disconnect power during mounting and installation.
5. The controller should be connected to its own isolated circuit breaker, and for best
results, the ground should be a true earth ground, not shared. Any attempt to bypass the grounding
will compromise the safety of users and property.
6.
The electrical installation of the controller must be performed by trained personnel only and
conform to all applicable National, State and Local codes.
7.
Operation of this product in a manner not specified by the manufacturer may result in damage
to equipment or persons.
8.
Avoid mounting in locations that expose the controller to direct sunlight, vapors, vibration,
liquid spills or extreme temperatures; less than 0°F (-17.8°C) or greater than 120°F (50°C).
EMI(electromagnetic interference) from radio transmissions and electric motors can also cause
damage or interference and should be avoided.
