PURON
®
(R-410A) REFRIGERANT
This unit is designed for use with Puron (R-410A) refrigerant.
Do not use any other refrigerant in this system.
Puron (R-410A) refrigerant is provided in pink (rose) colored
cylinders. These cylinders are available with and without dip
tubes; cylinders with dip tubes will have a label indicating this
feature. For a cylinder with a dip tube, place the cylinder in the
upright position (access valve at the top) when removing liquid
refrigerant for charging. For a cylinder without a dip tube, invert
the cylinder (access valve on the bottom) when removing liquid
refrigerant.
Because Puron (R-410A) refrigerant is a blend, it is strongly
recommended that refrigerant always be removed from the cyl-
inder as a liquid. Admit liquid refrigerant into the system in the
discharge line. If adding refrigerant into the suction line, use a
commercial metering/expansion device at the gage manifold;
remove liquid from the cylinder, pass it through the metering
device at the gage set and then pass it into the suction line as a
vapor. Do not remove Puron (R-410A) refrigerant from the
cylinder as a vapor.
Refrigerant Charge
The amount of refrigerant charge is listed on the unit’s name-
plate. Refer to Carrier GTAC2-5 Charging, Recovery, Recy-
cling and Reclamation training manual and the following pro-
cedures.
Unit panels must be in place when unit is operating during the
charging procedure. If unit is equipped with a head pressure
control device, bypass it to ensure full fan operation during
charging.
Charge checking and adjustments must be made while the sys-
tem is operating in Cooling only.
