NOTE: Refrigerant tubing must be routed to allow adequate
access for servicing and maintenance of the unit.
7.1 Tubing Size
For the correct tubing size, follow the specification for
the condenser/heat pump.

7.2 Tubing Preparation
All cut ends are to be round, burr free, and clean.
Failure to follow this practice increases the chances for
refrigerant leaks. The suction line is spun closed and
requires tubing cutters to remove the closed end.
NOTE: To prevent possible damage to the tubing joints,
do not handle coil assembly with manifold or flowrator
tubes. Always use clean gloves when handling coil
assemblies.
NOTE: The use of a heat shield is strongly recommended
when brazing to avoid burning the serial plate or the
finish of the unit. Heat trap or wet rags must be used
to protect heat sensitive components such as service
valves and TXV valves sensing bulb.
This product is factory-shipped with R-410A and dry nitrogen
mixture gas under pressure. Use appropriate service tools
and follow these instructions to prevent injury.
A quenching cloth is strongly recommended to prevent
scorching or marring of the equipment finish when brazing
close to the painted surfaces. Use brazing alloy of 5%
minimum silver content.
