Factory Equipment Refrigeration Amounts

ICE MACHINE HEAD SECTION

Each ice machine head section ships from the factory
with a R-404A refrigerant charge appropriate for line
sets up to 50’ in length (12.5 lbs.). The serial tag on the
ice machine indicates the refrigerant charge. Additional
refrigerant must be added for line set lengths between
50’ and 100’ (1.5 lbs.).

REMOTE CONDENSING UNIT

Each condensing unit ships from the factory pressurized
with 50/50 nitrogen helium mixture that must be removed
during the installation process (approximately 20 psig).

REFRIGERATION LINE SETS/TRAPS KIT

Refrigeration Rated Tubing and Trap Kits are shipped
capped with atmospheric pressure.
