Installing the MTC-4C
The MTC-4C must be installed by a qualified electrician.
Before installing or servicing the MTC-4C, switch OFF the power supply at the source.
Install the MTC-4C and all equipment connected to it according to local electrical codes.
Mount the unit on a sheltered, vertical surface, with the electrical knockouts facing down.
Use a screwdriver to tighten the screws in the enclosure. Do not use a drill or over tighten
the screws; this can crack the enclosure and ruin the watertight seal.
Use the electrical knockouts for bringing wires or cables into or out of the enclosure. Use
watertight strain reliefs or conduit connectors at all cable-entry points.
Before removing electrical knockouts, remove the cover to prevent damaging the control.
Do not make additional holes in the enclosure; this can damage the watertight seal or
components and void the warranty.
Only permanent split capacitor motors appropriate for variable speed control, or
shaded pole motors, can be used on the variable stage.
Fill out the information below to help configure your control and verify that you do not exceed the
electrical ratings of the MTC-4C.

Mounting the MTC-4C
When selecting a mounting location, follow the guidelines below.
Select a location that is away from sources of heat.
Mount the control on a solid, vertical surface, with the electrical knockouts facing down.
Failure to follow the mounting guidelines can allow moisture into the control and
will void the warranty.
