Warranty Waukesha Cherry-Burrell Warranty Seller warrants its products to be free from defect in materials and workmanship for a period of one (1) year from the date of shipment. This warranty shall not apply to products which require repair or replacement due to normal wear and tear or to products which are subjected to accident, misuse or improper mainte- nance.
READ AND UNDERSTAND THIS MANUAL PRIOR TO INSTALLING, OPERATING OR SERVICING THIS EQUIPMENT SPX recommends users of our equipment and designs follow the latest Industrial Safety Standards. At a mini- mum, these should include the industrial safety requirements established by: 1.
Care of Stainless Steel Waukesha Cherry-Burrell Care of Stainless Steel Stainless Steel Corrosion Corrosion resistance is greatest when a layer of oxide film is formed on the surface of stainless steel. If film is disturbed or destroyed, stainless steel becomes much less resistant to corrosion and may rust, pit or crack.
• VAPOR For steam or refrigeration. Special Considerations for The Vertical Votator II cylinder assembly is shipped for on-site installation on the mounting pole. When receiving the shipment, Vertical Votator II check for the following or multiples of (depending on the order) shipped separately in their own crate or crates: •...
Licensed Electrician in accordance with local regulations. Std. Votator II accepts 7-1/2 HP (5.5 kW), 10 HP (7.5 kW), 15 HP (11kw) or 20 HP (15 kW); Extra Heavy Duty Votator II accepts 25 HP (18.8 kW), 30 HP (22.5 kW) or 40 HP (30 kW).
Have a Licensed Electrician change the wiring so the rotation of the shaft is correct. Mechanical Seals The Votator II is furnished with either a single or double mechanical seal on both ends of the mutator shaft. Units furnished before 2005 were installed with either a single or double mechanical seal configuration.
Waukesha Cherry-Burrell Installation 2005 Mechanical Seal Design Units furnished between 2005 and 2012 have a one-piece chrome-oxide coated rotating body running against a stationary ceramic head insert. It can easily be converted to a double mechanical seal by adding secondary components to contain a steam or water flush.

Before starting a new unit, the system should be checked for media leaks at the Votator II cylinder, the media connections, and the piping to the cylinder using the following procedures: On units jacketed for steam or liquids, follow steps 1 through 6, and then drain condensate from cylinder.
Maintain minimum distance between protective cap and floor. See “Clearances” on page 9. Hydraulic System - Vertical The Vertical Votator II is furnished with a hydraulic cylinder, pump, motor, and fluid reservoir for removing and installing the Votator II mutator shaft and heat transfer tube.
4. Check hydraulic pump pressure by moving hydraulic lift foot away from Votator II unit and running cylinder in the full up, dead head position. At this point, it should be adjusted for a gauge reading of 300 to 400 psig at the pump.
Vertical Refrigeration System located in the addendum section and Votator II Vertical Refrigeration System drawing on page 18 showing the Process Flow Diagram of the Vertical Refrigeration System. It is necessary for on-site installation of these components to insure that the refrigeration system will mate properly with the Votator II cylinders.

Waukesha Cherry-Burrell Maintenance CAUTION: Failing to use the 8. Insert the Head Removal Tool (HRT) through the bearing and Head Removal tool can result in into the threaded end of the shaft, then slide the head over damage to the seal face. Use of the tool so that the seal face is past the end of the shaft.
Mutator Shaft Lubricate each fitting with a handgun, approximately three shots. Bearing Use a suitable NLGI Grade-2 bearing grease. (Not required for Extra Heavy Duty Votator II.) Shaft Remove shaft assembly at least once a week. Always use the removal Assembly trough skid to avoid bottom blades scoring the heat transfer tube.
Extra Heavy Duty Votator II Shaft Bearing The shaft bearing on the Extra Heavy Duty Votator II located in the opposite drive end head is a sealed bearing and does not require lubrication.
The shaft trough skid should always be used when removing or installing the mutator shaft in the Horizontal Votator II (or the Vertical unit if in a horizontal position) to prevent the blade mounting pins from scoring and damaging the tube wall.
You may not be aware that these units are considered pressure vessels under the ASME Code, and that SPX is the only facility authorized to make OEM repairs to the removable tubes that maintain their ASME Code certification. This certification is your assurance that the equipment meets its original design pressure rating.
It is also a requirement of most business insurance carriers, so you are helping to protect your company against potential fines and uninsured losses. With stakes this high, tube repair by SPX is the smart bet. Product Side The heat exchanger tube is designed to last a long time with little maintenance.
Waukesha Cherry-Burrell Maintenance Jacket Side For Units Using Steam, Water, Or Liquid The jacket side of the heat transfer tube has a sealed cover that allows the media flow to circulate around the tube. If it becomes coated with foreign matter and heat transfer is reduced, it can be cleaned by pumping a detergent solution compatible with the carbon steel jacket at a rate of about 100 gpm.
