Installation

Mounting

The junction box is located under the sensor portion as shown above. Use appropriate screws
and hardware as needed for mounting the instrument to the chosen surface.

Generally you will want to locate and mount the junction box first using two M4 or #8 screws.
Ensure that the head of the screw used for mounting the junction box fits inside the access tube.

Next mount the sensor portion on top of the junction box. The recommended mounting
hardware is M6 or ¼” screws. Four screws are needed.

Plumbing

The lower sections of the sensor are equipped with push to connect fittings for use in both the
intake and drain. Use ¼” OD tubing. Flexible polyethylene or polypropylene tubing is
recommended. To lower algae growth opaque tubing is highly encouraged. Make sure the flow
through is connected before starting the water flow. We recommended that the flow through be
tested for leaks before inserting it into the sensor.

Electrical Connections

All electrical connections are made inside the junction box. Choose the appropriate cable gland
for each connection.

Power Connection

A method of power disconnect should be provided prior to the instrument to allow for service.
This can be a power cord.

The MTOL+ can accept 100-240VAC 47-63Hz and requires approx. 80VA of power.
Connections are made the green terminal block on the left hand. This block is socketed and can
be removed for easy access.
