Refrigerant Charging Instructions - Howe 1000-RLE Installation & Service Manual

Refrigerant Charging Instructions
All Ice Flakers are shipped with a small holding
charge of dry nitrogen. Ice flakers must be
evacuated before charging.
1. Install a liquid line drier in the
refrigerant supply line between the
service gauge and the liquid service
port of the receiver. This extra drier will
ensure that all refrigerant supplied to
the system is clean and dry.
2. When initially charging a system that is
in a vacuum, liquid refrigerant can be
added directly into the receiver tank.
3. The approximate refrigerant charge is
listed in the table below. Do not over
charge.

Piping Charge is approximate additional pounds
refrigerant per 100 linear feet of liquid line
4. Start the system and finish charging
until the sight glass indicates a full
charge and the proper amount has
been weighed in. If refrigerant must be
added to the system through the
suction side of the compressor, charge
in vapor form only.
