Note About Evaporative Coolers
:
Ventilation:
Unlike traditional air conditioners, evaporative
coolers require an open ventilation system, not
a closed system. Both a fresh air source and an
exhaust opening are required to provide
correct air flow. Typically, a partially opened
window or door in each room where cooling is
desired will create correct airflow for optimum
effectiveness of an evaporative cooler.
NOTE
: For best results, open windows/doors
should not be on the windward side on the
house.
Water bleed or purge
:
Evaporative Coolers require a continuous supply of water to keep the media saturated for maximum cooling.
Water pumped into the cooler must be removed from the unit to ensure mineral and bacteria build-up do not
occur. This can occur with a gravity-fed steady bleed off stream or a timed purge system via a pump.
CAUTION:
Water expelled from the cooler must be routed away from any areas that could do damage to
foundations or other vulnerable areas.
NOTE:
Drawings in this manual are for illustrative purposes only and may reflect slight differences depending
on design level and configuration.
Features of the MasterCool® MCP44 Window Cooler
This cooler’s housing and frame are made of heavy-duty U-V resistant plastic to provide a light weight, easily
installable cooler. The unit is constructed in two basic sections to facilitate quick installation into traditional
sash windows or slider windows.
The high-efficiency rigid media offers superior cooling over other types of evaporative coolers.
