The installer must ensure that this control and its wiring are
isolated and/or shielded from strong sources of electromagnetic
noise. Conversely, this Class B digital apparatus complies
with Part 15 of the FCC Rules and meets all requirements of
the Canadian Interference-Causing Equipment Regulations.
However, if this control does cause harmful interference to
radio or television reception, which is determined by turning
the control off and on, the user is encouraged to try to correct
the interference by re-orientating or relocating the receiving
antenna, relocating the receiver with respect to this control,
and/or connecting the control to a different circuit from that
to which the receiver is connected.
Cet appareil numérique de la classe B respecte toutes les exi-
gences du Règlement sur le matériel brouilleur du Canada.
Radio Frequency Interference
Location
• Keep the control dry. Avoid potential leakage onto the control.
• Maintain relative humidity less than 90% in a non-condensing environment.
• Avoid exposure to extreme temperatures beyond 32-122°F (0-50°C).
• Install away from equipment, appliances, or other sources of electrical interference.
• Install to allow easy access for wiring, viewing, and adjusting the display screen.
• Install approximately 5 feet (1.5 m) off the finished floor.
• Locate the control near pumps if possible.
• Provide a solid backing which the enclosure can be mounted to. Example: plywood or wall studs.
• Use the conduit knockouts provided on the upper, lower, and back of the enclosure for wiring.
Installing the Enclosure
To prevent the risk of personal injury and/or death, make sure power
is not applied to the control until it is fully installed and ready for final
testing. All work must be done with power to the circuit being worked
on turned off.
Please be aware local codes may require this control to be installed
or connected by an electrician.
