Routine Maintenance
Inspection
The HPCC requires only simple, routine maintenance.
z Wipe off dust and dirt regularly.
z Check the connectors and cables for damage.
z Clean the connector contacts with alcohol or dry cleaning solvent.
z If dust has collected on the radiator coils, remove the screws around
the edge of the top panel, remove the panel, and vacuum the coils.
z The coolant level should be checked once a week, more often if the Cal
Cart is used continuously or in high ambient temperatures.
Note: The coolant level should be above the minimum mark on the
gauge even when the unit is on. To add coolant, See “Changing the
Coolant” on page 13.
