IMPORTANT SAFETY INFORMATION
READ ALL INSTRUCTIONS BEFORE USING THE SYSTEM
CAUTION
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 circuit breaker of the specified capacity.
Refer to local requirements regarding type and kind of
circuit breaker, power wiring, and control cable.

codes and ordinances. Use for future reference.
• Note to Installer – Be sure to leave these instructions with the
equipment owner.
• Note to Equipment 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 installation and service of this equipment.
• 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.

Observe all governing
Regulation of cables and breaker differs from each locality.
Be aware of these regulations prior to installation.
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.
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.
