Refrigerant
In consideration of our env ironment, Taylor
proudly uses only earth friendly HFC refrigerants. The
HFC refrigerant used in this unit is R404A. This
refrigerant is generally considered non-toxic and
non-flammable, with an Ozone Depleting P otential
(ODP) of zero (0).
However , any gas under pressure is potentially
hazardous and must be handled with caution.
NEVER fill any refrigerant cylinder completely with
liquid. Filling the cylinder to approximately 80% will
allow for normal expansion.
Use only R134a refrigerant that conforms to
the AHI standard 700 specification. The use of any
other refrigerant may expose users and operators to
unexpected safety hazards.
Refrigerant liquid sprayed onto the skin may
cause serious damage to tissue. Keep eyes and skin
protected. If refrigerant burns should occur , flush
immediately with cold water. If burns are severe, apply
ice packs and contact a physician immediately.
Taylor reminds technicians to be cautious of
government laws regarding refrigerant recovery,
recycling, and reclaiming systems. If you have any
questions regarding these laws, please contact the
factory Service Department.
W ARNING: R404A refrigerant used in
conjunction with polyolester oils is extremely moisture
absorbent. When opening a refrigeration system, the
maximum time the system is openmust not exceed 15
minutes. Cap all open tubing to prevent humid air or
water from being absorbed by the oil.
Refrigeration Charging and Line
Construction
The dispensing unit is shipped with a refrigerant
holding charge t hat is sufficient enough to pr event
moisture contamination (8 oz./227 g. R404A). This
holding charge will become part of the total system
charge.
The condensing unit is shipped with the total amount
of refrigerant required for a typical installation of 75 ft.
or less with a single dispenser. For other installation
configurations, use the following chart for line sizing
and for adding required refrigerant.

Note: Maximum line length is 150 ft. (45.7 m).
To meet individual installation requirements, lines
must be purchased and constructed locally.
Line Size
Liquid Line -- Single or dual dispensers require 3/8”
refrigerant grade copper tubing (hard or soft).
Note: Insulating the liquid line is recommended if it is
exposed to high ambient conditions. This will reduce
heat accumulation and prevent the formation of flash
gas in the liquid line.
