7. The boom le drain connecon is the primary drain for
this applicaon and condensate drain line must be aached
to this drain connecon. The top connecon of the three
drain connecons on the drain pan must remain plugged
for this applicaon. The boom le drain connecon is for
the secondary drain line (if used).

NOTE: If removing only the coil access panel from the unit, the lter
access panel must be removed rst. Failure to do so may result in
panel damage.
Do not install the air handler in a location that violates the
instrucons provided with the condenser. If the unit is located in
an uncondioned area with high ambient temperature and/or high
humidity, the air handler may be subject to nuisance sweang of
the casing. On these installaons, a wrap of 2” berglass insulaon
with a vapor barrier is recommended.

7 Refrigerant Lines
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 specicaon for the
condenser/heat pump.
7.2 TubingPreparaon
All cut ends are to be round, burr free, and clean. Failure to
follow this pracce increases the chances for refrigerant leaks.
The sucon line is spun closed and requires tubing cuers to
remove the closed end.
NOTE: To prevent possible damage to the tubing joints, do not
handle coil assembly with manifold or owrator 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 nish of the unit.
Heat trap or wet rags must be used to protect heat sensive
components such as service valves and TXV valves sensing bulb.
This product is factory-shipped with R410A 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.
Applying too much heat to any tube can melt the tube. Torch
heat required to braze tubes of various sizes must be
proportional to the size of the tube. Service personnel must
use the appropriate heat level for the size of the tube being
brazed.
