IMPORTANT SAFETY INFORMATION
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.
Make sure power is turned on for at least 12 hours after periods of
being powered down in an 32 °F (0° C) environment or lower.
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.
Regulation of cables and breaker differs from each locality, refer in
accordance with local rules.
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 brazing lines together. 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 copper tubing with adequate
wall thickness.

BEFORE YOU BEGIN
Read these instructions completely and carefully.
• IMPORTANT –
Save these instructions for local inspector's use.
• IMPORTANT –
Observe all governing codes and ordinances.
• Note to installer – Be sure to leave these instructions with the Consumer.
• Note to consumer – 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 split heat pump system.
• 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.
• Make sure to avoid wiring or plumbing inside the wall when installing.
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.

To prevent breaking of the pipe, avoid sharp bends. Bend the pipe
with a radius of curvature of 4 in. (100 mm ) or more.
If the pipe is bent repeatedly at the same place, it will break.
This manual should be given to the new owner and new user in the
event the building housing the HVAC system changes ownership.
Be sure to read Safety Considerations in the manual before
installation of the equipment.
The safety considerations stated below are divided into Warning
and Attention. The matters identified by these symbols relate to
serious consequences that can be caused by incorrect installation
and will likely lead to death or serious injury. In general; all
issues identified by the Warning and Attention symbols are very
important and relate to safety and security and should be strictly
abided by.
The installer should perform a run test when installation is completed
to ensure that all equipment operations are normal and safe.
When installing or servicing the connection kit, use proper
pressure testing and evacuation methods to ensure the system
is free of air and moisture before adding R410A refrigerant.
Air or moisture in the refrigerant system may cause abnormal
high pressure which could lead to equipment failure or personal
injuries.
During installation, if refrigerant leakage occurs, ventilation
measures should be taken, for the refrigerant gas might generate
harmful gases upon contacting the flame.
Insulate all refrigerant pipes to prevent heat loss and
condensation formation. Condensation from refrigerant piping
may cause property damage or cause a safety hazard.
