NOTE TO INSTALLER - READ THESE INSTRUCTIONS
CAREFULLY AND COMPLETELY before installing this unit.
Also, make sure the Owner's Manual and Service Instructions are
left with the unit after installation.
SAFETY CONSIDERATIONS
Installation and servicing of air-conditioning equipment can be
hazardous due to system pressure and electrical components. Only
trained and qualified personnel should install, repair, or service
air-conditioning equipment.
Untrained personnel can perform basic maintenance functions of
cleaning coils and filters. All other operations should be performed
by trained service personnel. When working on air-conditioning
equipment, observe precautions in the literature, tags, and labels
attached to the unit, and other safety precautions that may apply.
Follow all safety codes. Wear safety glasses and work gloves. Use
quenching cloth for unbrazing operations. Have fire extinguisher
available for all brazing operations.
Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

ICM FIOP Installation Instructions
Improper installation, adjustment, alteration, service, mainte-
nance, or use can cause explosion, fire, electric shock, or
other occurrences, which could cause serious injury or death
or damage your property. Consult a qualified installer or
service agency for information or assistance. The qualified
installer or agency must use only factory-authorized kits or
accessories when modifying this product.
Recognize safety information. This is the safety-alert symbol
When you see this symbol on the product or in instructions or
manuals, be alert to the potential for personal injury.
Understand the signal words - DANGER, WARNING, CAU-
TION, and NOTE. Danger identifies the most serious hazards,
which will result in severe personal injury or death. Warning
indicates a condition that could cause serious personal injury or
death. Caution is used to identify unsafe practices, which would
result in minor personal injury or product and property damage.
NOTE is used to highlight suggestions which will result in
enhanced installation, reliability, or operation.
The power supply (volts, phase, and hertz) must correspond to that
specified on unit rating plate.
The electrical supply provided by the utility must be sufficient to
handle load imposed by this unit. Electrical supply must match the
voltage requirements listed on unit rating plate.
This installation must conform with local building codes and with
NEC (National Electrical Code). Refer to provincial and local
plumbing or waste water codes and other applicable local codes.

Be sure to follow the installation instructions supplied with the Thermidistat™. - Page 6 (4.) ENH (enhanced) selection provides a 30 sec. cooling & heat pump on delay with no airflow, plus 150 seconds at 70 percent airflow and no off delay for added comfort. This will minimize cold blow in heat pump operation and could enhance system efficiency.

This configuration provides the following comfort enhance- ments: (a.) A 30 sec blower on delay with 150 sec at 70 percent airflow to allow the indoor coil to warm up or cool down before the blower is asked to deliver 100 percent airflow reducing the cold blow sensation at start up in heating and allowing the indoor coil to more quickly reach wet coil operating conditions in cooling. -

(2.) COOLING MODE— Press MODE button on the Thermidistat™ until COOL icon is displayed. Cooling begins within 10 sec. and remains on for 4 minutes. Observe that compressor, outdoor fan and indoor blower motors start after the call for Cooling. At the end of 4 minutes, the cooling cycle stops and the MODE reverts back to OFF. -
