CAUTION: Do not use sharp objects to adjust or select switches on the control
panel.
CAUTION: Do not overtighten the control panel clamp or articulated arm lock on
the MCH-1000(i). Mechanical damage may result.
CAUTION: Check for mechanical damage to any heat exchanger, blanket, or
other applied part, prior to connecting it to the MCH.
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 water tank contains at least 4 inches of sterile or 0.22-micron filtered
water, then add ice, from a sterile or 0.22-micron filtered source, 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, from a sterile or 0.22-micron filtered source, in the water tank. Note: The
MCH-1000(m) holds significantly less ice than the MCH-1000(i).
WARNING: Only use sterile or 0.22-micron filtered water or ice in the unit. DO
NOT use unfiltered tap water to rinse, fill, refill, or top-off the water tank.
CAUTION: Do not operate the MCH with less than 4 inches of sterile or 0.22-
micron filtered water in the 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
the valve should switch from cooling to recirculation mode approximately every ten
seconds (check for ten-second bursts of water flow in the water 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 set point.
