CardioQuip Modular Cooler-Heater Operator/Service Manual
1. Attach the desired heat exchanger and/or blanket circuits to the appropriate connectors on the
rear panel.
2. MCH-1000(i): Verify that the internal recirculation valve is in the NORMAL position.
3. Check the attached hoses to be sure there are no kinks, closed valves, etc. that would block
water flow through the hose loop.
4. Ensure that the cold water tank contains at least 4 inches of water, then add ice as desired.
The amount of ice needed to perform a given procedure is an operator decision; however, it is
recommended that each procedure be started with a full supply (approximately 35 lbs. / 16
kg) of ice in the cold water tank. Note: The MCH-1000(m) holds significantly less ice than
the MCH-1000(i).
CAUTION: Do not operate the MCH with less than 4 inches of water in the cold
!
water tank. Dry operation will cause equipment damage.
5. With the front panel mains power switch in the "off" position, plug the power connector into
a dedicated "hospital grade" power outlet. The outlet should match the voltage, frequency
and capacity listed on the MCH nameplate.
6. Turn on the mains power switch and ensure that the unit runs through a successful system
test.
7. Touch the "Prime" button to initiate the priming sequence. The pump should turn on and the
valve should switch from cooling to recirculation mode approximately every ten seconds
(check for ten-second bursts of water flow in the ice tank). Allow the system to prime until
no air bubbles appear in the external water lines. The priming sequence will automatically
run for 120 seconds, which should be sufficient for most applications.
8. Set the desired temperature setpoint.
9. Touch the "Run" button and monitor the water and patient temperature. Adjust the setpoint as
needed to maintain the desired patient temperature.
10. To halt operation, touch the "Standby" button.
WARNING: The MCH is not fully automatic. Monitoring of patient temperature and
!
rate of temperature change remains the responsibility of the operator.
11. If the water level in the tank is too high to accommodate additional ice, use the tank drain
valve or the system drain to drain excess water from the cold water tank.
