START UP
PLACEMENT
Make sure there is a clear, unobstructed path in front of the evaporative cooler to provide maximum airflow.
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 the platform is strong enough to hold the full weight of the evaporative cooler, including a
reservoir full of water. The evaporative cooler must be level and in the upright position and the casters should be locked to prevent
movement.
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 Comfort™ with FirePro Technology™ 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 reservoir is full of water, turn the pump on. Please note that the hose connection must be connected to a pressurized
water source before the pump may be primed. Open primer valve for three (3) seconds. Close primer valve. DO NOT leave primer
valve open, as it could cause flooding. When initially turning on the pump, the water level in the reservoir 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 of use to achieve maximum efficiency.
It is important to ensure 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 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
Before starting, make sure casters are in locked position. Start the fan by pushing the power lever into the on position.
