I. UNPACKING
A. Your Middleby Marshall GP Series Mixer will
arrive in a carton 54-3/8"H(1381 mm) x 351/4-D (895mm) x 32-7/8"W(835mm). Cut and
remove bands from around the carton.
Remove nails at bottom of carton to expose
the mixer and accessories. Before removing
mixer from the skid check packing list against
your order and inspect all Hems for damage
during transit. If any damage is found save all
packing materials and parts and arrangement
should be made to file a claim against the
carrier.
B. Loosen and remove the 4 lag bolts holding
the mixer onto the skid.
C. To process a valid claim the driver or other
representative of the delivering freight
company should immediately be notified and
requested to witness and certify in writing the
damage found. Interstate Commerce
Regulations require that the claim must be
initiated by the consignee.
D. After the damage has been certfied a
Middleby Marshall, Inc., Authorized
Service and Parts Distributor, should
immediately be contacted for assistance
in the repair or replacement of damaged
parts. Failure to do so could lead to added
costs.
lated room with proper storage facilities for
agitators and accessories.
C. Be sure to allow working space on the
controls side of the mixer.
D. It is recommended that the accessories all
be thoroughly washed and rinsed in very
hot, soapy water. The mixer should be
washed with mild soapy water and then
rinsed clean.
E. Electrical Connections - The Specification
Data Plate shown in Rgure 2-1 and located
on the outside of mixer must be noted for
proper electrical requirements before
connecting the mixer to the electrical
supply.
II. INSTALLATION
A. Bench and floor model mixers are both
designed to be placed on rigid level
surfaces. Since the operating weight of
this machine is approximately 250 tos
(112 kg), the bench or floor mounting
surface must be strong enough to support
this weight. The base of the mixer is
provided with mounting holes(refer to
base dimension drawing on Page 4) for
bolting to a bench, counter or floor, if
necessary.
B. Sanitary standards for food processing areas
require a clean, adequately lighted and venti

OPERATION CHECKS
installation
• Machines with cord:
A 7 ft. (2.1 m) cord and grounding plug comes
standard with all 115V/60Hz/1ph mixers. On
mixers with other voltages local codes govern
type of cord and wiring to the mixer. Consult your
local electrician
• Machines without cord:
IMPORTANT:
All electrical connections must be made by a
certified electrician.
1. Amps - Check amp rating on
mixer Specification Data Plate to
properly size your electrical wiring
and circuit breaker.
2. Voltage (115V, 220V, etc.) and
phase (1 or 3 phase) on mixer
Specification Data Plate must
correspond with voltage and
phase of your power supply.
Figure 2-2 Correct Planetary
Rotation
NOTE: If your machine is equipped with a 15 minute
timer turn the knob clockwise to the "Hold'position. The
mixer motor can then be operated manually for the preopera-tion checks by pushing the start and stop switch.
A. Before attaching any accessories to the mixer
make certain that the direction of rotation of the
planetary corresponds to the arrow located on the
head of the mixer as shown in Figure 2-2. Refer to
Section 3 for operating instructions to oerform the
above check.
3. Type of power supplied (60Hz
or 50Hz) must correspond with
rating on Specification Data Plate.
IMPORTANT:
The mixer must be wired and
grounded in accordance with
local codes, or in the absence of
local codes, with ANSl/NFPA latest edition.
4. This mixer has been completely
internally wired at the factory. To put into operation,
connect the power supply to mixer. This is the only
connection required.
If the planetary is not rotating in the proper
direction you must change wiring. On single
phase motors change wire connection as per
instructions inside motor cover. On three phase
motors reverse any two of the three line leads.
B. It is recommended that each of the mixer bowls,
agitators and accessories be assembled onto
the mixer to become familiar with their installation. Refer to Operation Section 3 of this manual
for bowl, agitator and accessory installation.
C. Operate the machine with an empty mixing bowl
and agitator installed in place to verify that there
is clearance between the rotating agitator and
inside of bowl. The agitator and bowl clearance
has been set at the factory and should be approximately 1/4".
