Refrigeration Charging and Line
Construction
The dispensing unit is shipped with a refrigerant
holding charge that is sufficient enough to prevent
moisture contamination (8 oz./227 g. HP62). 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.

Dispenser Required Charge
Less than 22.8 m Single 4.5 kg
More than 22.8 m Single 5.4 kg (add 0.91 kg)
Less than 22.8 m Dual 5.9 kg (add 1.4 kg)
More than 22.8 m Dual 6.8 kg (add 2.3 kg)
Note: Maximum line length is 150 ft. (45.7 m).
Note: 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.
Single Dispensing Installations
Suction Line - Less than 75 ft. (22.8 m) total line
length requires 5/8” refrigerant grade copper tubing
(hard or soft). Maximum 5/8” tubing length is 75 ft.
(22.8 m).
Note: Suction lines must be insulated.
Suction Line - More than 75 ft. (22.8 m) total line
length requires 3/4” refrigerant grade copper tubing
(hard or soft). Maximum tubing length is 150 ft. (45.7
m).
Dual Dispensing Installations
(One Condenser, Two Dispensers)
Individual Suction Line - Requires 5/8” refrigeration
grade copper tubing (hard or soft) from each dispenser
to the common suction tube.
Common Suction Line - Requires 3/4” refrigeration
grade copper tubing.
Note: Lines must be insulated and requires a 5/8” x
3/4” reducer fitting at the quick disconnect
connections. See Figure 1 below.
Note: Use 5/8” wire to attach the quick disconnects to the other components.
