Need Help with Selectivend Dr. Pepper Machine Identification

[FlightTest]

Howdy,

I just picked up a Selectivend Dr Pepper Machine and need some help with identifying which model it really is.

I believe it is a late 1950s Selectivend S-96 that was modified at some point to add the multi vend front door.   I can't find a data plate but there is a sticker inside that says a conversion was completed and it is now a model C100A-1. However I can not find any information on that model number.

Can any of the knowledgeable people on here help guide me?

Is there any information out there on this model

Thank you very much!

This is only my second machine so I am very much a newbie.

This S/V model may in fact be a conversion form a single flavor/interior rack vendor to a multi-vend shelf vendor, thus it may not have a data plate per say.  S/V (Select Vend) did produce some shelf vendors with glass doors as shown, and they also converted other manufactures models over to shelf style vendors notably the Vendo V39 & V83's.  also note the vending chute block-off plate just below the bottle door, this indicates that it is indeed a converted vendor.

Thank you so much for your clarification.   I have tried searching for any documentation available for the C100A-1 model but have found nothing.   

The Dr Pepper stickers on the side are dated 1964 so maybe that is when the conversion was completed. 

Do you think it was a modified S96 or something different?

I have included a couple more pictures to possibly help with the identification.

Sorry I am having trouble with resizing the pictures to meet the size requirements.

Yes, it’s a converted S96... turned into an S100 vis-à-vis the bottle rack, So it’s quite correct to be calling it an S100 now.

Thank you so much.  I hope to get to it pretty soon and see what works and what needs some help.

I was able to wire up the compressor and it started right up and the evaporator started getting frosty.  The wiring is in rough shape and the thermal overload switch has a crack on the side.  It has a Blissfield compressor tag but some of it is very hard to read. The compressor fan is missing so I am planning to order one soon.  It appears it also had some kind of cardboard fan shroud that has remnants of the cardboard under 4 retaining bolts on the condensor frame.

The thermal overload switch has a large brass blade/connector that goes right to the compressor.  I have not seen any replacement of that type available so I may just put it back together with a 3 in 1. 

Does anyone know what size condenser motor and fan size the Selectivend S-96/S-100 used?  Is it the typical 4Watt motor that most seem to use? 

Thanks for your help.

You’re correct it’s a SV-96 . And give it a couple days on responses there are a few members that are refrigerating people

Yes, between a 4 to a 6 watt motor is Ok, most modern machines use up to a 9-watt for the condenser & a 6 watt for the evaporator fan, but the lighter the wattage the quieter the motor ( I call the vibrational noise "Thrumming" if you put a larger wattage motor on a smaller fan blade) a 4-6 watt will be able to rotate a 6" or 7" fan blade, a tri-blade ( OEM style) moves more air than a 5-segment modern fan but needs a larger motor to spin it & more clearance between it & the condenser... if you go with a too-small motor vs a larger (say 10") fan blade with a 2-4 watt motor, the motor may not spin up to full speed & it will act like it's stalling out & quickly overheat.    So try not to go large than a 8" fan with a 6 watt motor, I hope this helps you out.

Thank you so much for the tip.  I will look for a motor and the 3 bladed fan.  Hopefully I can buy or make a fan shroud to help with the flow.

I really appreciate you sharing your knowledge.

Funtronics sells fan shrouds for Vendo models, they may fit your machine as well,  also sell the motors & 3-blade fans

I have been working on getting the machine all up and running and wanted to ask about the evaporator fan airflow direction.   The set up that came in it blows air down through the round horizontal evaporator with the cold air directed at the bottom of the machine.   I thought it was supposed to draw air up through the evaporator and blow it up to the top of the machine.   Do you all think it has the incorrect motor rotation?

[johnieG]

It should pull air through the evaporator first, then up the back & over the bottles/cans... Basically bottom to top.
 So In your case, yes it's backwards ( wrong rotation) if you are still using the original fan-blade with a reversed rotation motor, it will have poor air circulation, because the reversed blade spin will just "bat" the air around & not really circulate it from the bottom to the top

Thanks JohnieG.  That is what I suspected.   And I appreciate your guidance. I wonder how long it was used with the motor/fan spinning the wrong direction?  The good news is that is still seems to cool really well. 

Thanks again for the help. I am sure there will be more questions in the future.

Putting in the new fan that directs airflow in the right direction made for a huge improvement.  I did have to work with the new fan blade quite a bit because it was pretty far out of balance.  I worked on trimming the blade pitch to make sure all of the blades were positioned the same.   However it still shook like crazy where the old fan blade was smooth.  I put a clip on one blade at a time until it started to run smooth. Then once I found the blade that needed weight I drilled a small hole in it about mid point and put in a very small screw.  At first it still had a small wobble so I kept filing away at the screw end until it finally ran nice and smooth.   

The new blade made the Temps way more even in such a tall machine.   I am still working on getting the thermostat set right.  Currently it shuts off around 27 degrees and turns on at 35 with the temp sensor about 12 inches above the bottom of the machine.  I put several water bottles in it at different heights and the bottom ones seem to average around 33 to 34.  And the tops are around 35 to 36.  So I think that's getting close to where I want it.   

It's nice to have it up and working.   Now I need to go get some bottles to try it out for real!

Thanks again for all of your guidance.

I'm happy you got it up & running again...well done!
