CAUTION: Use only hospital-approved bactericidal agents that are non-acidic
!
and non-foaming. Operation with unapproved agents may cause equipment damage.
7. Run the MCH through five (5) standard priming cycles, or one extended priming cycle, to
fully mix and circulate the cleaning chemical (10 minutes total). At some point during
this step, set the recirculation valve (if so equipped) to INTERNAL for at least 10-15
seconds, to ensure that disinfectant reaches all sections of the internal plumbing.
8. Scrub the cold water tank and outlet screens with a nylon brush. It is imperative that the
tank and screens be thoroughly cleaned to ensure disinfection. The screens may be
unscrewed and removed to assist in cleaning. Be sure to replace the screens before
operating the MCH.
9. Open the system and tank drain valves and drain the unit completely. With the drain
valves open, flush the unit with clean water.
10. Close the drain valves and fill the cold water tank to maximum level. Run the MCH
through a priming cycle to flush residual cleaning chemical from the system.
11. Turn off the mains power switch, and drain the system completely. If necessary, repeat
the flushing sequence until all cleaning chemical is removed from the system.
12. With a brush, clean the fan guard and air intake grille on the underside of the unit. All
debris should be removed so that air flow is not impeded.
13. Inspect all plastic tubing on the hose kits. Any tubing that is clouded and/or has lost its
flexibility should be replaced.
14. Perform the cleaning procedure listed under After Every Use. The system can now be
returned to use or stored. Always store the system drained and dry.

Annually

The MCH should receive a complete preventive maintenance service check by an authorized
CardioQuip service technician every 12 months. The Annual Preventive Maintenance Checklist
at the end of this manual may be used by qualified biomedical personnel to verify essential
performance and safety of the MCH.
If tap water with a high mineral content is used in the MCH, or if mineral deposits are noticed in
the MCH water path, then the device should be treated annually with a descaling chemical like
Liquid Dezcal™, using the Quarterly cleaning procedure. Do not mix the Dezcal with other
chemicals or disinfectants.

Disposal Procedures

Dispose of water drained from the MCH using a standard facility, floor, or greywater drain. Prior
to disposing of the MCH itself (via sale, transfer, recycling, etc.), the Quarterly maintenance
procedures should be performed and the MCH prepared for storage. Internal components of the
MCH and its modules may contain trace amounts of lead or other toxic substances. When
discarding the MCH or any of its modules, consult local regulations regarding the disposal of
used electronics and medical equipment.
