W

D

(D)

H

3.3.2 Environmental setting The unit can be operated properly under the following environmental conditions for a long time running without any problem.

No direct sunlight on Laboratory Refrigerator

Ambient temperature: 18OC to 30OC

Relative humidity not to exceed 85%

Altitude not to exceed 2000m (6,562 feet)

Keep incubated shaker away from high frequency noise produced by equipment and/or machinery, such as electrical distribution panels, welders, induction heating mechanism, and large amounts of SCR (Silicon-controlled rectifiers). See Section 6.4—Troubleshooting, E l e c t r i c a l — f o r t h e e f f e c t s o f h i g h f r e q u e n c y n o i s e .

Connect the incubated shaker to earth grounded terminals only.

3.4 Locking/Unlocking Casters & Leveling the unit

The caster assembly allows for easy movement, locking and leveling of the unit. For proper agitation, it requires the unit to be level side to side and front to back. Use the following instructions to ensure the unit is level.

Tool required

Step 1: Place the unit in its location. Step 2: Lower the foot of each caster by turning the red height adjustment counterclockwise until it hits the floor. Turn the height adjustment a quarter turn or more to ensure the unit’s weight is taken off the caster. This will lock the unit in place.

Step 3: Place a level on the top of the door

and check for level side-to-side and front-to-back. Step 4: Turn the height adjustment to raise

or lower the unit until one is level.

3.5 Power connection

Main power should be connected to the unit according to the following procedure. STEP 1: Check the socket located at the upper part of the back side.

STEP 2: Power cord should be connected to the socket at the back side.

STEP 3: Press on the main switch upward after power cord is connected to the socket. .

Ensure that the unit should be connected to a power supply that is an appropriate voltage, phase capacity. Failure to connect to a proper connection of a power will cause the risk of fire, electric shock and personal injury

Never use a forked socket, or a double-tapped socket. Failure to obey a safety warning will cause a drop in a line voltage, resulting in a loss of poor and causing risk of fire by turning the cable. Use the power cord only supplied with the unit.

3.6 Pre start-up checks à Make sure all unit and wall outlet electrical connections are tight. à Make sure caster feet are lowered and have locked the unit in place. à Make sure the unit is level side to side and front to back. à Make sure there are no flammable or explosive liquids inside of chamber
