D. Starting the pump and adjusting the water flow.
Once the sump tank is full, moving the pump switch to the “ON” position will turn on the pump.
When initially turning on the pump, the level in the sump will drop suddenly and restart the flow of supply
water. This is a normal condition, as the cooling pads require a large amount of water for proper wetting.
When the PORT-A-COOL® unit is new, the new pads will require an initial ‘breaking-in’ period. This
period is required for the pads to begin readily absorbing water. It may require up to a week to achieve
maximum efficiency.
It is important to insure that the spray bar is properly adjusted when first starting the water flow in the
PORT-A-COOL® unit. Increasing the flow using the SPRAy BAR ADJUSTMENT valve on the side of the unit
makes this adjustment.
E. Starting the fan.
(Cooling pads must be installed and caster brakes must be engaged.)
Starting the fan is as simple as turning the fan switch to the ‘ON’ position or to one of the available speeds
on the multi-speed models. On the multi-speed model, it is preferred to step slowly through the speeds
allowing the fan to obtain its full speed at the LOW speed before going to MEDIUM and before going to
HIGH.
Proper adjustments should leave the pads saturated with water, but not flooded. Pads should appear wet,
however, cascading amounts of water can actually reduce cooling efficiency. Proper adjustment will prevent
problems and increase cooling capacity.
When turning the fan off at the end of the day or week, the pump should be turned off about 15 minutes
before the fan to allow the cooling pads to dry. This will increase the life of the pads.
