STEP 7. CONNECTING THE LINE SETS
Important Information — Read Before Proceeding
Follow the detailed instructions for connecting the refrigerant pipes to the indoor unit and outdoor unit. The
warranty is only honored if the lines are installed correctly as described in the instructions.
• Do not remove the sealing caps until immediately before you install the lines.
• To prevent leaks, ensure that the male condenser couplers are completely free of dirt. Moisture or foreign
bodies will adversely affect the function of the male condenser couplers, leading to a risk of refrigerant loss
(not covered by the warranty).
• Only install refrigerant lines outdoors, in dry weather.
• The refrigerant lines must not be installed and then plastered over. Line hide can be used to help disguise
the line set outdoors if wanted.
• Please make sure that refrigerant is never allowed to enter the environment. Improper handling of refrigerant
may be harmful to your health and the environment. Always wear work gloves and goggles when handling
refrigerant.
• Do not smoke during the installation work.
• The equipment must never be operated without the refrigerant lines connected, otherwise the equipment
will be greatly damaged.
• The screw connections may only be tightened using the appropriate open-ended wrench. Remember that if
they are tightened with too little torque they will leak.
• If you are not confident about connecting the refrigerant line yourself, it is imperative that you contact our
customer service team, refrigeration contractor or a certified HVAC technician.
• IMPORTANT! The male condenser couplers are only designed for one-time installation. Their seal cannot
be guaranteed if they are installed on more than one occasion. This will also void the warranty.
For your safety, always wear goggles and work gloves when
connecting the pipes.
CAUTION
CONNECTING THE REFRIGERANT LINE SET TO OUTDOOR AND INDOOR UNIT
For unparalleled ease and flexibility, your Perfect Aire Multi-Zone Ductless Mini-Split system offers two
installation options for connecting the refrigerant lines to the indoor and outdoor units. The QUICK CONNECT
METHOD offers the quickest and easiest installation solution. To accommodate the many and varied
installation site conditions the FLARED CONNECTION METHOD is still an option, but this must be performed
by an HVAC professional.
IMPORTANT - This product has been designed and manufactured to meet ENERGY STAR® criteria
for energy efficiency only when installed using the FLARED CONNECTION METHOD and matched with
appropriate coil components. However, proper refrigerant charge and proper air flow are critical to achieve
rated capacity and efficiency. Installation of this product should follow Perfect Aire’s refrigerant charging and
air flow instructions. Failure to confirm proper charge and airflow may reduce energy efficiency and shorten
equipment life.
