Aloha, we have a Taylor #794 batch freezer - what refrigerant should we use (data panel has been removed, but we have been told it was manufactured before 1995) ? Mahalo

    we've been told that it should be R-502 or R-404A - ?

  • Paul B Sep 29, 2010

    the spec sheet for the 2010 model of #794 states: "Refrigeration System
    Two, 9,500 BTU/hr. R404A.
    Separate Hopper Refrigeration (SHR), One, 400 BTU/hr. R134a"

    so, the cylinder refrig sys requires R404A - I only have R-502, can I use the 502 if we vacuum out the system completely

  • Paul B Sep 29, 2010

    mahalo (thanks) and just to help me understand, what is the primary difference(s) between 404A

  • Paul B Sep 29, 2010

    sorry, I forgot to ask you... what should the "normal" pressure be for 404A/ 502 - I've heard between 100-140??

  • Paul B Sep 29, 2010

    OK, thanks for all your help - aloha and mahalo nui loa (thanks very much)

Then, the refrigerant is R-22 and the type of oil is mineral.

    Click on the following link to get the specs of the whole unit. The Refrigerant gas is R134a.

    Good day!!

  • Rene J Solis Sep 29, 2010

    I meant the Hopper is R134a and the actual Cooling system has two compressors that use R404a refrigerant.

    So your system do use R404a and R134a refrigerant.

    Refrigeration System

    Two, 9,500 BTU/hr. R404A.

    Separate Hopper Refrigeration (SHR), One, 400 BTU/hr. R134a.

    (BTUs may vary depending on compressor used.)

  • Rene J Solis Sep 29, 2010

    The two are compatible and if you have no other choice.......

  • Rene J Solis Sep 29, 2010

    I am working on that, give me a few

    Basically, the R502 is a blend of R-22 and R115 and is not as Eco Friendly as the R404a which is 95% less damaging to the Ozone Layer. Both systems are for low temperature compression refrigerants. To be on the safe side, I would use the R404a and not risk system corrosion in the system and eventual compressor failure. If it is an old machine and you just need it to work for a couple of yrs. then you know what to do. Good Luck!1

    Here are the descriptions of the two types of refrigerant:

    R502 refrigerant. Azeotrope blend of R22 and R115 refrigerants. R22 mass proportion constitutes 48,8%, and R115 - 51,2%. It is related to CFC group, has the following ecological characteristics: ODP = 0,33; GWP = 4300. Non-explosive, low-toxic and chemically inert to metals. R502 resolvability in oils, heat transfer coefficient during boiling and condensation are close to the corresponding values for R22. Peculiar feature: R502 is poorly soluble in water. Tolerance concentration of R502 in the air constitutes 3000 mg/m3. Its volumetric refrigerating effect is higher and discharge temperature is approximately 20 oC lower that those of R22, which positively manifests itself on the temperature of electric motor winding during operation of hermetic refrigeration compressor. R502 refrigerant was used in low-temperature compression refrigerating facilities.

    Until concerns about depletion of the ozone layer arose in the 1980s, the most widely used refrigerants were the halomethanes R-12 and R-22, with R-12 being more common in automotive air conditioning and small refrigerators, and R-22 being used for residential and light commercial air conditioning, refrigerators, and freezers. Some very early systems used R-11 because its relatively high boiling point allows low-pressure systems to be constructed, reducing the mechanical strength required for components. New production of R-12 ceased in the United States in 1995, and R-22 is to be phased out by 2020. R-134a and certain blends are now replacing chlorinated compounds. One popular 50/50 blend of R-32 and R-125 now being increasingly substituted for R-22 is R-410A, often marketed under the trade name Puron. Another popular blend of R-32, R-125, and R-134a with a higher critical temperature, and lower GWP than R-410A is R-407C. While the R-22 and other ozone depleting refrigerants are being phased out, they still have value and can be easily sold

What is process to winterize a Taylor ice cream machine?

To winterize a Taylor 794, or almost any water-cooled Taylor machine, we need to get all of the water out of it. Follow the steps outlined here.
1. Remove the supply water hose from the water source.
2. Remove the rear panel of the machine.
3. Locate the water valves. Pictured below.
4. Have one person open 1 water valve. (You can scissor two screw drivers to take pressure off of the spring.)
5. Blow out all of the water with an air compressor until only air comes out of the drain hose.
Repeat step 4 and 5 for the other side.

I had the same ER DH error code, and my refrigerator began to warm up. I replaced the defrost thermostat assembly part # 6615JB2005H which is located inside the freezer, on the right side behind the white plastic panel. I accessed it by removing the freezer door, all components inside the freezer, and the tracks mounted on the sides of the freezer. Be careful when removing the white panel because a fan is mounted to the left side of the white panel and plugs into the back left side of the freezer compartment.
Found the green technical data sheets under the refrigerator in a small plastic bag near the front.

Whirlpool side by side refrigerator

Could be blocked up in the shute. remove all ice from the freezer and check that the ice shute (leading to the dispenser outlet) is clear. Let the freezer create a batch of ice (normally about 4 to 5 hours) and see if it dispenses then. If not , it could be a failed auger motor. That is the main corkscrew looking drive which pulls the ice into the shute. Check the icemaker in the freezer, and look for a button on the side or underneath the icemaker. Most manufacturers put one there to test the icemaker. Press the icemaker ice dispenser button and see or hear if the auger is turning.

I have a Taylor 794 soft serve machine. The left side is too soft.

Viscosity adjustments should not have to be made frequently on these machines. If you change products a lot, such as flavors of yogurt, minor adjustments may be required. If your machine uses 3 phase electricity and it machine has been moved or any electrical work performed you may want to check the beater rotation, the beater should rotate clockwise inside the barrel viewing from the front, if you look at the gear box from the back, the pulley should be turning clockwise as well. Otherwise, there is a fine tuning potentiometer on the control, you must remove the front cover to see it. Clockwise is colder/thicker. I recommend small adjustments. It is best to read the amp draw on the motor to see what type of amps it is drawing. If your mix is soft and your motor is drawing 4 amps, you may have another type of problem such as a bad motor. The board and control can also fail giving these problems. There are many things to check in addition to these. Hope this will help you get started.

Drive shaft stuck

if you can't get it out thru the barrel then you will need to remove the gear box behind the shaft and push it out that way. you should align the shaft afterwards to not rub also make sure your not lubing the bolt pattern on the shaft. after its out use the cleaning brush and clean the coupling.

Taylor 794 machine won't freeze yogurt

Try these sites:

The thermostat has gone bad or the refrigerant charge is low...check the thermostat to make sure that it is calling for the refrigeration system to run, make sure power is getting to the compressor and then make sure the compressor is cooling properly...
If compressor is running them the t-stat is okay and there is a problem it is cycling on and off then the t-stat is bad.....
if it is running continuously then you probably have a refrigerant needs to be found, fixed, and the system recharged...
