Section 1 Safety Information
Your Thermo Scientific MaxQ 7000 Shaker has been designed with
function, reliability, and safety in mind. It is your responsibility to install
it in conformance with local electrical codes. For safe operation, pay
attention to Notes, Cautions, and Warnings throughout the manual.
This manual contains important operating and safety information. The
user must carefully read and understand the contents of this manual prior
to the use of this equipment.
Warnings
To avoid electrical shock, always:
1. Use a properly grounded electrical outlet of correct voltage and current
handling capacity.
2. Disconnect from the power supply prior to maintenance and servicing.
To avoid personal injury:
1. Do not use in the presence of flammable or combustible materials -
fire or explosion may result. This device contains components which

The Thermo Scientific MaxQ 7000 series of bench top, water bath shakers
are available in either analog or digital control configurations:
• SHKA7000, SHKA7000-1CE: control temperature by a
Proportional/Integral/Derivative (PID) microprocessor-based
controller. Solid-state control maintains time and speed and is
adjustable with rotary dials. Analog tachometer displays speed in RPM,
verifying accuracy of speed setting.
• SHKE7000, SHKE7000-1CE: control temperature, time and speed by
a Proportional/Integral/Derivative (PID) microprocessor-based
controller that is adjustable on a keypad in 1 rpm increments with
switches. Flashing display indicates power interruption. Pressing any
key will clear display. Speed and time set points are automatically
reactivated after power is restored. Audible and visual signals indicate
when temperature deviates more than 2°C over set point-unit will
automatically shut down. Audible and visual signals indicate when
water level is too low.
Temperature range: SHKA7000, SHKA7000-1CE, SHKE7000,
SHKE7000-1CE, 5ºC above ambient to 65°C with accuracy in flask at
37°C ±0.2°C. Cooler temperatures are attainable using the optional cooling
coil.
In addition, all versions offer:
• Seamless stainless steel bath chamber with rounded corners
• Space efficient tubular heaters
• Set points are retained by non-volatile memory that automatically
reactivate after power is restored
• User adjustable over temperature thermostat controls temperature if
main controller fails
• ½ inch (1.27 cm) triple eccentric orbital drive
• 6 permanently lubricated ball bearings
Note Propylene glycol must be used as the media instead of water at
temperatures above 90°C.
• 35 lb (15.9 kg) platform load capacity at safe speeds less than 400 rpm
for SHKA7000/SHKA7000-1CE and less than 500 rpm for
SHKE7000/SHKE7000-1CE

Section 4 Unpacking and Installation
The shipping carton should be inspected upon delivery. When received,
carefully examine for any shipping damage before unpacking. If damage is
discovered, the delivering carrier should specify and sign for the damage on
you copy of the delivery receipt.
Open the carton carefully making certain that all parts are accounted for
before packaging materials are discarded. After unpacking, if damage is
found, promptly report it to the carrier and request a damage inspection
properly.
Important Failure to request an inspection of damage within a few days
after receipt of shipment absolves the carrier from any liability for damage.
Call for a damage inspection promptly.
Use the packing list below when unpacking to verify that the complete
unit has been received. Do not discard packing materials until all is
accounted for.
The following items are included in the shipment:
Adapter Fitting (to drain tank) - 950-170-00
Male Connector (Digital Only) - 420-359-00
Splash Baffle (Qty. 2) - 014-290-00
If any items are missing, contact Technical Services.
Put the shaker on a level table or bench capable of supporting the weight
of the shaker with any accessories while in operation. Place shaker near an
electrical outlet that matches the unit nameplate requirements. Allow
approximately 2” (5 cm) of clearance around the unit for free air
convection, accessory attachments and user convenience.

Unpacking and Installation
Electrical
Requirements
SHKA7000 and SHKE7000 Series shakers require a 120VAC, 50/60 Hz
power source. They are supplied with a 3-wire line cord and should be
plugged into an outlet designed for 3-prong plugs. If an extension cord is
used, it also should be the 3-wire grounded type. For an outlet designed to
accept 2-prong plugs (ungrounded), it is required that a qualified
electrician replaces the outlet with a new, grounded type.
SHKA7000-1CE and SHKE7000-1CE Series shakers require a 240 VAC,
50/60 Hz power source. Power cords are supplied.
If a plug must be installed, use only the 3-prong grounded type, rated for
the unit load requirements and matching the power outlet. Make sure the
green ground wire is secured to the plug ground terminal.
To eliminate hazard of electrical shock, make sure floor around shaker is
dry. In the event of accidental spilling or splashing of liquids, clean up
and/or neutralize the spilled liquids before continuing.
Disconnect the shaker from the power source when not in use.
Warning Do not operate shaker with a damaged electrical cord. s
1. Place shaking platform on suspension arms. The short leg of each arm
goes under the platform, the longer arms stand up and out from the
platform. Bolt each arm in place to fit flush against the edge of the
platform. Refer to Figure 4-1 on the following page.
2. Remove the clamping knobs from the support arms and set them aside.
Place the suspension arms over the support arms and align the holes.
Bolt the arms together with the threaded bolt attached to the knob.
Arms may be squeezed together to align the bolt holes. Be sure to use a
flatwasher and a lockwasher on each knob. Insert splash baffles in
guides at front and back of the tank.
3. Fill the water bath to the desired level. For best operation of the
equipment, fill the unit with sterilized distilled water or equivalent.
The acceptable resistivity range is 50K to 1M ohms (conductivity 1 to
20 micro Siemens). A non-chlorine-based bath fungicide/bactericide
can be added to increase the useful life of bath water.
Caution Do not operate shaker with an unbalanced load. Platforms should
be loaded for optimum stability and operation. Do not lift shaker by the
platform. s
