USAGE WITH NON-MANITOWOC

CONDENSING UNITS

Manitowoc Condensing Units are specifically designed for usage with a Manitowoc Flake/Chiplet Ice Machine Head Sections. Manitowoc Flake/Chiplet Ice Machines will not operate with non-Manitowoc condensing units.

!Warning

Installation of a Remote Condensing Unit may require the use of special equipment for placement. Trained and qualified personnel are required for proper rigging and lifting.

!Caution

The 60-month compressor warranty (including the 24-month labor replacement warranty) will not apply if the Manitowoc Ice Machine and remote Manitowoc Condensing Unit are not installed according to specifications. This warranty also will not apply if the refrigeration system is modified with a condenser, heat reclaim device, or other parts or assemblies not manufactured by Manitowoc Ice, Inc.

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.) see chart below.

Series	Charge
QF2200/QF2300	0’ to 50’ linesets 12.5 lbs (5.7 kg)
RFC2085/	50’ to 100’ linesets 14.0 lbs (6.4 kg)
RFC2385

!Caution

Never add more than nameplate charge to the refrigeration system for any application.

!Warning

Potential Personal Injury Situation

The ice machine head section contains the refrigerant charge. Installation and brazing of the line sets must be performed by a properly trained and EPA certified refrigeration technician aware of the dangers of dealing with refrigerant charged equipment.

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.
