It is highly recommended that you do not open or close
the stop valves when the outdoor temperature is below
-5°F (-21°C), as this may cause refrigerant leakage.
Do not touch the fins of the coil. Touching the coil fins
could result in damage to the fins or personal injury.
Ensure the power circuit capacity is adequate for all loads
connected to the electrical service panel. Increase the
conductor and panel capacity if the total electrical loads
exceed the power source capacity.
Contact the power utility if the power provided is below
equipment rating plate requirements.
Be sure to install a breaker of the specified capacity.
Refer to local requirements regarding type and kind of
breaker, power wiring, and control cable.
Regulation of cables and breaker differs from each
locality. Be aware of these regulations prior to installtion.
Do not use existing refrigerant lines.
Use refrigerant tubing that is clean and free of any
contamination which may cause damage to the system,
including sulfur, copper oxide, dust, metal chips, powder,
oil, or water.
Avoid coupling lines whenever possible. Use a continuous
length of copper tubing, as oxides formed during improper
brazing techniques can damage the equipment.
Do not use copper pipes that have a collapsed,
deformed, or discolored portion (especially on the interior
surface). Otherwise, the expansion valve or capillary tube
may become blocked with contaminants.
Improper line sizing will degrade performance. Peak
pressure of R410A is much higher than R22. Use ACR
copper tubing with adequate wall thickness.
Use a tubing bender to change piping direction. Make
sure the radius of the bend is no less than 4”.
If the pipe is bent repeatedly at the same place, it will
break.
BEFORE YOU BEGIN
Read these instructions completely and carefully.
•IMPORTANT – Save these instructions
for local inspector’s use.

codes and ordinances.
• Note to Installer – Be sure to leave these instructions
with the owner to use for future reference.
• Note to Owner – Keep these instructions for future
reference.
• Skill level – A licensed certified technician (to handle
refrigerant R-410A, recovery, etc.) and a qualified
electrician are required for equipment and service of this
air handler system.
• Use team lift for installation of this product.
• Proper installation is the responsibility of the installer.
• Product failure due to improper installation is not covered
under the limited warranty.
• For personal safety, this system must be properly
grounded.
• Protective devices (fuses or circuit breakers) acceptable
for installation are specified on the nameplate of each unit.
• Piping or wiring within walls must be protected per local code.
CAUTION
• Aluminum electrical wiring may present special
problems - consult a qualified electrician.
• When the unit is in the STOP position, there is still
voltage to the electrical controls.
OUTDOOR REQUIUREMENTS
There is a matching air handler and must be used with
the outdoor units as rated by AHRI.
The outdoor sections are manufactured with an
interchangeable refrigerant metering device for optimum
refrigerant control and system performance. The AHRI
rating may require the metering device be changed, in
some cases, to meet the rated performance.
