Running Specifications Expansion Valve Setting Ambient Temperature Normal Operating Head Pressures R404A 340--12: 38 -- 39 PSI (262 -- 268 kPa.) 340--27, 341 & 342: 35 -- 36 PSI (241 -- 248 kPa.) Low Side Pressure Low side pressure = expansion valve setting. To adjust the low side pressure, place the gauge on the low side suction port at the compressor.
General Installation Instructions The following are general installation instructions. For complete installation details, please see the check out card. Uncrate the machine. Inspect the unit for damage. Report any damage to the Taylor factory immediately. This piece of equipment is made in the USA and has USA sizes of hardware. All metric conversions are approximate and vary in size. Site Preparation Review the area the unit is to be installed in before uncrating the unit.
Note: This unit is provided with an equipotential grounding lug that is to be properly attached to either the rear of the frame or the under side of the base pan near the entry hole for incoming power, by the authorized installer. The installation location is marked by the equipotential bonding symbol (5021 of IEC 60417-1) on both the removable panel and the equipment’s frame, as well as on the diagram. THIS UNIT HAS MANY SHARP EDGES THAT CAN CAUSE SEVERE INJURIES.
Beater Rotation A back flow prevention device is required on the incoming water connection side. Please refer to the applicable National, State, and local codes for determining the proper configuration. Beater rotation must be clockwise as viewed looking into the freezing cylinder. The following repairs must be performed by an authorized Taylor Service Technician. Refrigerant Disconnect all power to the unit. Failure to follow this instruction may result in electrocution.
Compressor Warranty Disclaimer Environmental Notices _________________________________ The refrigeration compressor(s) on this machine are warranted for the term indicated on the warranty card accompanying this machine. However, due to the Montreal Protocol and the U.S. Clean Air Act Amendments of 1990, many new refrigerants are being tested and developed; thus seeking their way into the service industry.

Refrigeration System Systems and Controls 14 Models 340/341/342
Torque Control Function/Operation To product a hard slush, the beater, torque arm, torque rotor and adjustment spring will have to changed. The adjustment spring is stronger, therefore, the torque arm has to work harder to trip the microswitch. The thickness (and indirectly the temperature) of the slush is controlled by a sensing device called the Torque Switch. The refrigeration system is brought on and off by a microswitch.
Component Replacement If the timer, microswitch, toggle switch or solenoid is faulty, simply replace by: Note: DO NOT attempt any repairs unless the MAIN POWER SUPPLY TO THE FREEZER HAS BEEN DISCONNECTED. Failure to follow this instruction may result in electrocution. Note: DO NOT attempt any repairs unless the MAIN POWER SUPPLY TO THE FREEZER HAS BEEN DISCONNECTED. Failure to follow this instruction may result in electrocution. Step 1 Remove the front switch cover assembly.
Section 3: Troubleshooting Models 340/341/342 S General Troubleshooting Guide S Troubleshooting Torque Components 17 Troubleshooting
General Troubleshooting Guide PROBLEM 1. 2. 3. 4. No product is being dispensed with the draw valve opened. The product is too thin. The product is too stiff. The walls of the freezing cylinder are scored. Troubleshooting PROBABLE CAUSE REMEDY a. Improper mixing of product. a. Carefully follow the directions for mixing the product. b. There is a mix low condition. b. Add mix to the mix hopper. c. The torque arm is not installed. c. Install the torque arm. d.
PROBLEM 5. REMEDY a. There is lubrication on the square end of the drive shaft. a. Remove lubrication from the square end of the drive shaft. b. The corners of the drive shaft and/or drive coupling are bent. b. Replace the drive shaft and/or drive coupling. a. There is improper or inadequate lubrication on the drive shaft o-ring or seal. a. Use an approved food grade lubricant (Example: Taylor Lube) and follow the lubrication procedures. b. Bad or missing o-ring or seal on drive shaft. b.
Troubleshooting Torque Components C. If incorrectly sized, damaged or improperly lubricated o-rings are used, the rotor, door, torque arm, torque rotor and torque lever may be damaged. D. If the torque arm is missing, the product will freeze and the pulley belt will begin slipping. The beater reset will then deactivate freezer operation. In addition, torque components may be damaged.
