Upon arrival Hot Well unit was on. The water was drained and the unit was inspected. Left side overload is bad, ohmed out the heater and it was found to have 53 ohms, the same as a new one. Talked to customer and they will wait for overload. Need hi limit. Will order and return. 9/4/20 The water was drained and new high limit switch was installed. Hot well was turned on and all heaters are functioning.
