Side Note : couple of years ago we ordered a STR225 refrigerator for our showroom. It arrived nicely crated with no dings or dents. Having only pictured this product in a brochure, we were was amazed at how nicely constructed and how large this unit was. After a simple unpacking, the unit was carried into our showroom.
After a two hour wait to make sure that the compressor oil had settled, we attached a 10 amp fuse and ring terminals to the power cables and then attached the unit to a 12 volt battery that was being charged by a 80 watt solar module.
The unit made a faint whirring sound which let us know that it was running. We walked away and began locking up for the day. Even though the instructions said that we should wait approximately 2 hours before loading it up with food, I decided to take a peek after only an hour. To my amazement the inside of this fridge felt like a freezer !
I hurried over to our service department and told our senior technician that he had to see this thing to believe it. He opened the fridge door and placed his hand against the side wall and could not believe it either.
We became concerned that these Ultra High Efficiency had shipped us a freezer instead of a fridge so we went back to our loading area to look for the packing slip and discovered that there was no mistake, the unit was what we ordered, a refrigerator not a freezer. We decided that we should adjust the thermostat, so that we didn't wind up freezing the sodas that we had placed in our new fridge.
If you happen to be in the area, be sure to stop by and share an ice cold one (soda that is !) with us from this amazing machine, you wont believe it either. All from a single 80 watt solar panel !
