6. POWER CORD
Design-Aire comes complete with a grounded 3-prong electrical cord. Do not remove or alter ground on plug,
serious damage could occur. Do not modify the plug of your unit if it will not fit in your duplex. Have a proper
duplex installed by a qualified professional.
7. PRE-FILTER
Your Design-Aire is equipped with disposable pre-filters, which are manufactured from bonded synthetic media
set into a moisture resistant “beverage” board. Pleated pre-filters supplied with your Design-Aire carry an
efficiency rating of MERV 7 (Minimum Efficiency Reporting Value) to change the pre-filters simply lift it off the
pre-filter housing and replace dirty pre-filter with new pre-filter.
8. PRE-FILTER MAINTENANCE
Disposable pre-filters cannot be washed or cleaned and should be changed regularly. You can determine a
proper schedule for your facility based on your specific room conditions. Pre-filters should be inspected on a
monthly basis or as room conditions dictate and replaced when necessary.
