CAUTION: Do not block the air vents around the sides of the TEC Module.
Inadequate airflow will cause overheating and premature failure of the TEC
Module.
CAUTION: During procedures requiring significant cooling, sterile or 0.22-
micron filtered ice may be needed. The TEC Module is designed for low-
demand normothermic cooling applications.

Refrigeration Module

The Refrigeration Module (MCH-10RMS) replaces the lid on the
MCH-1000(i) with an enclosed condensing unit that generates a block of ice
in the tank. With room-temperature sterile or 0.22-micron filtered water in
the tank, the Refrigeration Module will chill the water to 3˚C in about 75
minutes, and begin to make ice in about 1.5 hours.

Refrigeration Module Installation

Remove the factory tank lid from the MCH-1000(i). Team-lift the
Refrigeration Module from its shipping crate per the Lifting
instructions, and set it in place on top of the MCH tank. Always
keep the Refrigeration Module upright. Take care to avoid
bending or damaging the two chiller plates and temperature
probe that hang down into the tank. The Refrigeration Module
may be installed with its power cord toward the front or rear of
the MCH-1000(i), whichever is more convenient.

Refrigeration Module Operation

Connect the Refrigeration Module's power cord to a hospital-grade
electrical circuit. Fill the water tank until the sterile or 0.22-micron
filtered water level reaches the top edge of the chiller plates. Turn on
the mains power switch on the rear panel of the Refrigeration Module.
The Refrigeration Module can be left running all the time; it will not
freeze the entire tank. Use the hinged cover to inspect the water tank
and chiller plates, and to add sterile or 0.22-micron filtered water or
ice if necessary. Keep the cover closed under normal operation.
