RECOVERY AND RECHARGING PROCEDURES
Do not purge refrigerant to the atmosphere. Capture
refrigerant using recovery equipment. Follow the
manufacturer’s recommendations.
Important
Manitowoc Ice assumes no responsibility for the
use of contaminated refrigerant. Damage resulting
from the use of contaminated refrigerant is the sole
responsibility of the servicing company.
Important
Replace the liquid line drier before evacuating and
recharging. Use only a Manitowoc (OEM) liquid line
filter drier to prevent voiding the warranty.
CONNECTIONS
These ice machines are critically charged. There are no
refrigerant access ports on these ice machines.
1. Locate the high and low side process tubes.
2. Install a piercing valve (saddle valve) on both the high
and low side process tubes.
Important
• Remove piercing valves after charging.
• Unit is critically charged. Nitrogen must be purged
through the system while brazing to prevent build up
of copper oxide in the refrigeration system.
• Manifold gauge set must be removed properly to
ensure that no refrigerant contamination or loss
occurs. A quick disconnect is required for the high
side connection.
