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.
2. Remove the switch control panel from the top of cooler, by inserting a small screwdriver into
the tap slots and pop loose.
3. The pump is connected to the control via the white plastic clip. Disconnect the pump clip and
feed the plastic clip through the control box into the cooler.
4. The pump cable is connected to the cooler by twist clips that are mounted in the side of the
corner between the left pad and the front of cooler. You may have to remove that pad to get
to the clips. Also there may be cable ties holding cable to the motor mounting bracket.
Remove the pump from cooler when cable is free.
5. Reinstall the new pump in reverse. Being sure to reconnect the cable in the twist ties and
secure the cable in a manner of which it stays clear of fan blade when cooler is running.
Reattach the pump clip in the control box and reinstall the control panel in its place. Be sure
not to pull any other wires loose from control switches when you have panel loose.
6. Reinstall the control panel into the cabinet making sure it is seated. And YOU’RE DONE!
Float Valve Replacement or Adjustment: (Disconnect power supply before this procedure.)
The float valve is mounted to the left side of cooler if you are facing the front grill. It is held in
place by the retaining nut that is visible from the outside. The rubber washer is between the nut
and cabinet. The rear panel will have to be removed to adjust the float (if the water level is too
high or too low) or remove and replace a float that has failed to shut of water supply. Note: Be
sure that the PSI of the supply water is within the 50 PSI spec. before determining the float has
failed.

2. Remove any hose adapters attached to the float valve nipple.
3. Remove the rear panel assembly as instructed in Section 5.
