MAINTENANCE:
The Ice Qube air conditioning system is designed to provide many years of trouble-free operation with
minimal amount of maintenance. Primary maintenance consists of checking the condition of the
ambient air filter and the condensate management system.
1.
Ambient Air Filters
: It is recommended that the ambient air filters be inspected and cleaned
regularly; frequency will depend upon ambient conditions. To check the condition of the air
filter, it is recommended to first remove electrical power from the Ice Qube system. Next,
locate the filter cover and filter, (location will vary by model). Slide the filter from the filter rack
through the end slot and clean by soaking in warm soapy water. Rinse with clean water. Use
a shop-vac to remove excess water from the filter before returning it to the system. Replace
the filter if it is showing signs of deterioration.
NOTE: If rain or wash down hoods have been installed, a filter would not have been
supplied, therefore no filter maintenance is required. However systems
equipped with rain or wash down hoods will require regular condensing
section maintenance by qualified personnel. For systems equipped with
filters, it is recommended to have a spare clean filter in stock in order to
prevent prolonged cooling system downtime. The dirty filter may be cleaned
at a more convenient time.
