START UP
PLACEMENT
1) Make sure there is a clear, unobstructed path in front of the evaporative cooler to provide maximum airflow.
2) If the evaporative cooler is positioned on a raised platform, ensure the platform is stable, well constructed and will not allow
the evaporative cooler to tip over. Ensure it allows for the full weight of the evaporative cooler, including a tank full of water. The
evaporative cooler must be level and in the upright position and the casters should be locked to prevent movement.
3) If placed near a wall or other obstruction, position the evaporative cooler a minimum of 3 feet (0.9 meters) from the wall or
obstruction with the KUUL evaporative media facing the wall. This allows the unrestricted flow of warm air to the KUUL evaporative
media. When using multiple evaporative coolers in close proximity, be sure to aim each evaporative cooler so the air flows complement
each other to achieve maximum cooling capacity.
STARTING THE PUMP AND ADJUSTING THE WATER FLOW
Once the tank is full of water, pressing the “PUMP” button on the digital control panel will turn on the pump. When initially turning on
the pump, the water level in the tank will drop suddenly and restart the flow of supply water. This is a normal condition, as the KUUL
®
evaporative media requires a large amount of water for proper wetting.
New evaporative media will require an initial ‘breaking-in’ period. This period is required for the KUUL
®
evaporative media to begin
readily absorbing water. It may require up to a week to achieve maximum efficiency.
It is important to ensure that the water flow to the media is properly adjusted to lowest position when first starting the water flow in
the evaporative cooler. Increasing the flow using the water adjustment valve (see Quick Setup in this manual) makes this adjustment.
Proper water adjustment should leave the media saturated with water, but not flooded. Media should appear wet. When properly
adjusted, some dry streaks will appear at the interface of the KUUL
®
evaporative media.
When turning the evaporative cooler off at the end of the day or week, the pump should be turned off about 15
minutes before the fan to allow the KUUL
®
evaporative media to dry.
STARTING THE PORTACOOL EVAPORATIVE COOLER
Start the fan by pressing POWER on the digital control panel, then adjust to desired speed. Before starting, make sure casters
are in locked position.
