OPTIONAL COOLING MODULES
Thermo-Electric Cooling (TEC) Module
TEC Module Installation
Fill the MCH-1000(m) water tank with sterile or 0.22-micron
filtered water to approximately ⅔ full, to a depth of about four
inches (10 cm). Store the factory tank lid in a safe place, and
carefully fit the TEC Module onto the tank. If water begins to
overflow, drain some water from the unit or lift the TEC Module
and remove some water from the tank. The TEC Module may be
installed with its power cord toward the front or rear of the
MCH-1000(m), whichever is more convenient. Connect the TEC
Module's power cord to a hospital-grade electrical circuit.
TEC Module Maintenance
Check the air intake vents on the TEC Module periodically for dust buildup or blockage.
Use compressed air as often as needed to clean dust from the vents and the internal
components. Clean outer surfaces with an EPA-registered tuberculocidal disinfectant wipe.
CAUTION: Do not plug the TEC Module into the same electrical circuit as the
MCH-1000(m). The TEC Module draws approximately 1.5 Amps of power, so it
may be able to share a circuit with other equipment. The MCH-1000(m) requires
a separate dedicated 20 Amp circuit (see Initial Operation Check).
CAUTION: Do not damage the cooling probes. Damaging the protective
coating on the probes may cause corrosion and premature failure of the TEC
Module.
CAUTION: The water tank should be no more than ⅔ full of sterile or 0.22-
micron filtered water when installing the TEC Module. If the water depth in
the tank is more than 4 inches (10 cm), overflow and spillage may occur.

The TEC Module (MCH-11TEC) replaces the lid on the
MCH-1000(m) with an enclosed pair of cooling probes that
continuously chill the water in the tank, maintaining a water
temperature of approximately 5–10˚C depending on ambient
conditions and load. This provides adequate cooling for most
normothermic procedures.
