FIGURES & DIAGRAMS
Although There Is a Large Demand At Startup,
the Compressor Only Runs at Medium Speed
• Regardless of demand the system will always start and run
at an intermediate speed for one minute. Subsequently the
speed may increase signifi cantly.
Humidifi cation or Dehumidifi cation Setpoints Are
Not Being Satisfi ed
• The fi rst priority of the system is to achieve the temperature
setpoint(s). While under most circumstances it will also
satisfy humidity setpoints, its ability to accomplish this is
signifi cantly affected by a variety of installation-based factors
and circumstances.
In an iQ Zone System, the system does not
respond promptly to changes in setpoint or mode
• With zoning systems additional delays may be noticed.
Most commonly this is due to no new changes processed
until zone dampers have completed any prior operation.
For example, an extra minute delay is deliberately included
when one or more zones are closed.
MAINTENANCE
IMPORTANT:
Be certain the electrical power to the outdoor unit
and the furnace or air handler is disconnected before
doing the following recommended maintenance.
• Inspect the indoor air fi lter monthly. Clean or replace it at
the start of each heating and cooling season or when an
accumulation of dust or dirt is visible. If the indoor coil needs
to be cleaned, contact a qualifi ed service technician.
• Inspect the condensate disposal line from the indoor coil at
the beginning of the cooling season to make sure it is not
obstructed.
• Remove any leaves, grass clippings, and debris from the
outdoor unit coil, being careful not to damage the aluminum
fi ns. Dirt may be cleared from the coil by using a water hose
directed through the discharge fan grille toward the outside
of the unit.
• Have a yearly inspection by a qualifi ed service technician
to ensure that the system is performing at its optimal level.
