MIXER INSTALLATION

Handling

Never lift a mixer by its shaft. Grovhac mixers & agitators should be handled by lifting only on the
gearbox or drive unit, while also carefully supporting the mixer shaft & blades.

Mounting

Mount your mixer on a level tank surface and fasten securely; your mixer may fasten using bolts,
threaded bung, or clamps. For C-Clamp mixers, never use tools to tighten clamp; hand tighten only.

The following illustrations show recommendations for mounting mixers and number of propellers
required.

For proper mixing action in tanks without baffles, mixer

shafts should be mounted 10º to 20º off vertical and 10º to
20º off the tank center line, as shown in Illustrations A & B.

If the depth of the liquid (y) is approximately equal to the

diameter of the tank (x), a single propeller may be used, as
shown in Illustration C. Dual propellers are usually
specified when the liquid depth (y) is 1.5 times (or greater)
the diameter of the tank (x), as shown in Illustration D. The
bottom propeller should be placed 1 to 2 propeller
diameters from the bottom of the tank.

Set-up

Mixers with Air Motors

Install your air motor using air lines the same size or the next size larger than the intake port of the
motor.

It is recommended that you install a moisture trap and filter/lubricator in the air line ahead of the motor.
Excessive moisture in the air line can cause rust formation in the motor and might also cause ice to form
on the muffler (due to expansion of air through the motor). Lubrication is necessary for the bearings,
shaft seals, and to prevent rust formation.

Note: allowing excess moisture or foreign particles from the air line to enter the motor will nullify any
warranties.

If operating the motor intermittently without automatic air line oiler, place motor in accessible position
for easy lubrication.

A non-reversing motor will operate properly in one direction only; a reversible motor will work equally
well in both directions; all Grovhac mixers are designed to run clockwise when viewed from the top of
the motor.

When coupling or connecting the motor to a driven member, avoid any end or side thrust and never

hammer on the shaft.

Mixers with Electric Motors

For electric motors without electrical plugs, check local codes for wiring instructions.

Before making electrical power connections, check for proper grounding of motor and application. All
electrical contacts and connections must be properly insulated and enclosed. Prior to connecting to the
power line, check nameplate for proper voltage and rotation connection. All Grovhac mixers are
designed to run clockwise when viewed from the top of the motor.

Caution: Your electric motor should be installed in compliance with the National Electric Code,
OSHA, and any other applicable codes, Voltage at motor not to exceed + or – 10% of nameplate
voltage. Authorized person should make all electrical connections.

Motor should be located in a clean and dry area with adequate ventilation. Motor must be protected from
the weather, if installed outdoors.

Warning: use only explosion-proof motors for applications with explosive gases or materials
present.
