I just bought a house that has a 5 year old ultratemp installed. I dont see any drain installed as per the manual, and I dont even see where a drain could be installed. There is only water in and out, Relay connection, and the electrical connection. There is some water in the pockets at the bottom of the cabinet, and some dripping when its running. What location should a drain be installed on these? Its on a concrete pad now. Id like to clean all the landscaping debris from the bottom of the cabinet, and properly install a drain and hose to get the water in the right area.
