INSTALLATION

UNPACKING

Immediately after unpacking the mixer, check for possible shipping damage. If this machine is found to be damaged after unpacking, save the packaging material and contact the carrier within 15 days of delivery.

Prior to installation, test the electrical service to make sure that it agrees with the specifications on the machine data plate.

LOCATION

Place the mixer in its operating location. There should be adequate space around the mixer for the user to operate the controls and to install and remove bowls. The area above the mixer should allow the top cover to be removed for routine maintenance and servicing.

Holes are provided in the base for permanent bolting to the floor; although this is not necessary in normal installations. Four plastic plugs are supplied with the mixer to plug these holes if they are not used.

Once placed in the operating location, level the mixer.

1. Remove the top cover screws and the top cover.

2. Place a level on the machined surface of the transmission case (Fig. 1).

3. Slide shims under the legs (base) of the mixer as required to level it front-to-back and side-toside.

NOTE: Do not replace the top cover until installation is complete.

Check Lubrication Before Use

This mixer is shipped with oil in the transmission. Mixer production prior to September 2002 will have oil in the planetary. Mixer production after September 2002 will have grease in the planetary. Check oil levels before starting mixer. Refer to Lubrication, pages 16 to 17, for applicable lubrication procedures.

Check Rotation (Three-Phase Machines Only)

Three-phase machines must be connected so the planetary rotates in the direction of the arrow on the Drip Cup. To check rotation:

1. Set the Gear Shift Lever on 1.

2. Apply power to the mixer, set the electromechanical timer on HOLD or, if equipped with a programmable timer controller, set it on [ -- : -- ]. With the Bowl Support all the way up, momentarily run the machine by pushing the START and then STOP buttons.

3. If rotation is incorrect, disconnect electrical power supply and interchange any two of the incoming power supply leads.
