1 Introduction
The Fann Constant Speed Mixer, Model 686CS is designed to mix cements to
comply with American Petroleum Institute (API) specifications and recommended
practices.
As deeper wells are being drilled, heavier weight cements are needed to withstand
higher downhole pressures. The Model 686CS has a heavy-duty motor that can
handle thicker cements at the proper speed.The mixer has control buttons that the
operator can use to program the proper mixing speeds and times. One control
button, the API Profile button is preprogrammed with the API standard settings,
12,000 rpm for 35 seconds. These programming features save the operator time.
For specification details, refer to the following API documents:
•API Recommended Practice for Testing Well Cements, API RP 10B-2
•API Specification for Cements and Materials for Well Cementing,
API Spec 10A

2 Safety
This blender is similar to any mixing blender and does not present any unusual
hazards.
Follow these recommended safety practices:
1. The operator should always wear safety glasses in case the mixture splatters
when adding ingredients.
2. The operator should not drop any foreign objects in the container while mixing
is occurring. These foreign objects could strike the operator or damage the
mixing blades and container.
3. The Model 686CS should be plugged in to a properly grounded outlet with the
ground prong in place.
4. Do not use extension cords.
5. Always remove the plug from the receptacle before performing any work on the
mixer base.
6. Do not immerse the mixer in any fluid or spray it with any fluids.
7. The blender should be at a comfortable height for the operator. The operator
should be able to add ingredients without straining to reach the mixer. Also, the
mixer should be close enough to shut it off quickly if necessary.
8. The mixing cup should be cleaned thoroughly after use to prevent the buildup
of cement or other deposits. These deposits can cause accelerated wear of
components. The mixing blades should be checked daily for damage. Damaged
or worn blades should be replaced immediately.
