Draining the Cooler Tank
Unscrew drain cap from drain assemble and drain away water. You may tip the unit carefully to the
drain side to help drain all the water out.
Removal and Replacement of Xel50 Cooling Media.
The cooling pads are made from a special resin impregnated craft paper specially designed for
evaporative cooling. They will last many years if maintained properly and water quality is maintained.
It is not necessary to remove the pads to clean them.
Inspect the pads for deposits of calcium on the air entering side. If the flute cells are clogged or the
pad is very heavy it may be time to change the media. New OEM Xel50 media can be purchased where
you bought the cooler. Follow these steps for replacing the pads.
1. With access panel removed, simply pull off the pad retainer disc from the pad pin. Older models
may have a pushed on pin that will need to be pulled away using pliers to grasp disc and pull
away. Be careful not to break the pin although the new pads will come with new pins and disc.
The newer models will have a threaded disc that will unscrew from the pin
2. With disc removed, remove the pins from the pads and carefully remove pads from the fixed
side mounting frame. Then do the same for the back panel or panels.
3. Xel50 pads are made with a 45/45 flute and can be installed either side to the frame. Just make
sure the distribution pad that is fixed to the top of the new media pad is at the top. This allows
water get onto the top of the pad evenly. The installation of the pads is opposite of the removal,
install the pad, insert pins and install the retaining disc. YOU’RE DONE… It’s that easy.
4. Reinstall the back panel and you are ready to use the cooler again.
Pump Maintenance and Replacement. (Disconnect power supply before this procedure.)
The submersible pump is mounted inside the tank to the bottom with a retention bracket. While you are
cleaning the cooler the pump may be removed and the strainer cap on the bottom of pump can be
cleaned of debris. If pump has failed and needs replacing follow these steps:
1. Remove retention bracket.
