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.
