MasterCool ADA5112 - User Manual
This installation and operation manual covers single-inlet evaporative coolers, focusing on their setup, maintenance, and troubleshooting to ensure safe and efficient performance. The document addresses key areas like electrical wiring (including 120V/240V connections, grounding, and amperage adjustments), water-cooling system installation (flood valves, overflow protection, and scale prevention), seasonal maintenance (filter cleaning, bearing lubrication, pump checks), and ventilation requirements for optimal airflow. It also includes troubleshooting guides for common issues such as motor cycling, inadequate cooling, or leaks, along with model-specific technical specifications and exploded diagrams of component assemblies.

READ AND SAVE THESE INSTRUCTIONS
SAFETY RULES
1. Read all instructions carefully.
2. Electrical connections should be done by a qualifi ed electrician,
so that all electrical wiring will conform to your local codes.
3. Always turn OFF POWER and UNPLUG motor and pump inside
the cooler before installing or performing any maintenance.
4. Your cooler will run on either 120V or 240V A.C., single phase,
60 Hz (cycle) current.
5. Motor and pump have a grounded, molded plug and an automatic
thermal overload switch which will shut motor off when it
overheats. The motor will restart automatically when it cools
down.
WARNING:
To reduce the risk of fi re or electric shock, do not use
this fan with any “solid-state fan speed control device.”

READ CAREFULLY ALL OF THIS MANUAL BEFORE INSTALLING THE UNIT
Evaporative cooling is nature’s way of cooling. When air is
moved over a wet surface, water is evaporated and heat is
absorbed. When stepping out of swimming pool with the
wind blowing, evaporative cooling makes you feel cool, even
though the air may be warm.
This unit works on the same principle. Air is drawn across
wet fi lter pads where the air is cooled by evaporation and then
circulated throughout the building. It is this combination of
cooled air and the movement of air over the skin which makes
it feel cool.
Unlike refrigeration systems which recirculate the air, an
evaporative cooler continually brings in fresh air while
exhausting old air. You are completely replacing the air every
2 to 4 minutes by opening windows or doors, by using Up-
Dux
®
ceiling vents, or a combination of both. The air is always
fresh, not stale, laden with smoke and odors as happens with
refrigerated air conditioning.
