I have a Nor Lake walk in freezer that I am putting together. I am in need of a wiring diagram for the condenser unit. It is a model # SE 26-758-D.\r\nThe condenser unit has two fans, two defrost heaters, an over temp switch, and two temperature switches that I don't know anything about. The unit is 220volt. Any help greatly appreciated. Tom

The evaporator drains into pan with a coil from the discharge line. The design is intented to sub-cool the liquid refrigertant as well as evaporate the condensation from the coil. Unfortunately the engineer started as career a shipping clerk and never received any further training.  There isn't enough heat or running time to evaporate the condensation from the coil.
The solution is fairly simple
A plastic tube  drains water out of the evaporator in the pan. You can extend the tube and add a defrost pan handled by your refrigeration wholesaler. Wire it so it is on whenever there is power to the unit.  This should get rid of the excess water. These pans are also used on some self contained coolers and freezers. They come in either 120 volts or 220 volts. [email protected]

I have a generic wiring diagram that I use on all my installs that works very well. It is basically the same for most all commercial walk in freezers. Send me a email address and I'll scan and forward what I have.
