Refrigeration Module Maintenance

Check the air intake & exhaust vents on the Refrigeration Module periodically for dust
buildup or blockage. Use a vacuum or 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. During the Quarterly Maintenance Procedure, remove the
Refrigeration Module from the system according to the Lifting instructions and wipe down
the chiller plates and underside of the unit with an EPA-registered tuberculocidal disinfectant
wipe.

Refrigeration Module Storage

The Refrigeration Module can be stored on its own, standing upright on its stainless steel
stands; however, it is top-heavy and presents a tip hazard when stored in this manner. If
possible, it should be stored in place on top of the MCH, with the unit drained and dry.
WARNING: Ensure that airflow from the
MCH Refrigeration Module does not
violate the sterile field. The Refrigeration
Module employs a low-airflow heat exchanger
that is designed to function safely and
efficiently within the airflow pattern of a
standards-compliant Surgical Ventilation
System, when positioned as shown in the
diagram at right. The MCH should be
positioned at least 6ft (2m) from the patient,
with the rear-panel water connectors pointing
either directly toward, or directly away from,
the patient. In this position, the Refrigeration
Module exhaust air flows parallel to the
operating table. The Airflow Directional Hood
(MCH-10ARH) may be installed to redirect the
exhaust downward. Even with Airflow
Redirection Hood installation, proper MCH
orientation should be followed to ensure
exhaust air flows parallel to the operating
table. During certain procedures—e.g., with a
substandard surgical ventilation system, or
with immunocompromised or infectious
patients—it may be desirable to power off the
Refrigeration Module, to avoid any risk of
circulating airborne contaminants that may be
present in the room.
