5.1.2 Location Considerations
NOTICE
Risk of leaking water. Can cause equipment and building damage.
Do not mount units over equipment or furniture that can be damaged by leaking water.
Install a watertight drain pan with a drain connection beneath ducted cooling units and
ceiling mounted water/glycol condenser units. Route the drain line to a frequently used
maintenance sink so that running water can be observed and reported in a timely manner.
Post a sign to report running water from the secondary drain.
Locate the evaporator unit over an unobstructed floor space if possible. This will allow easy access for
routine maintenance or service. Do not attach additional devices (such as smoke detectors, etc.) to the
housing because they could interfere with maintenance or service.
Do not install units in areas where normal unit operating sound might disturb the working
environment.
Avoid locating the evaporator unit with the optional air grille kit in confined areas that affect the
airflow pattern. Such locations could cause short cycles, downdrafts and air noise. Avoid installing the
unit in an alcove or at the extreme end of a long, narrow room. Avoid installing multiple units close to
each other. This could result in crossing air patterns, uneven loads and competing operating modes.
