5-2 Reciprocal Shaking Water Baths
Electrical Connections -
Important For personal safety, this apparatus must be properly grounded.
1. The power cord provided on this unit is equipped with a three-prong
(grounding) plug which mates with standard three-prong grounding wall
receptacle to minimize the possibility of electric shock hazard from this
apparatus. If in doubt the user should have the wall receptacle and circuit
checked by a qualified electrician to make sure the receptacle can provide
adequate current and is properly grounded.
2. Where a standard two-prong wall receptacle is encountered, it is the personal
responsibility and obligation of the user to have it replaced with a properly
grounded three-prong wall receptacle. Do not, under any circumstances, cut
or remove the third (ground) prong from the power cord. Do not use a two-
prong adapter plug.
Determine the total amount of current being used by other apparatus connected
to the circuit that will be used for this apparatus. It is critical that the added
current demand (see nameplate) of this and other equipment used on the same
circuit does not exceed the rating of the fuse or circuit breaker.
Caution Be sure that the power supply is of the same voltage as specified on the
nameplate. The power cord is the mains disconnect. Make sure the outlet is easily
accessible after installation.
Shaker Clip Installation - The spring retainer clips provided are designed to firmly
hold flask clips in shaking tray holes.
1. It is important that these clips be inserted into tray holes before inserting
optional flask clips (refer to list of Accessories). To meet specific applications,
a variety of flask sizes can be utilized simultaneously.
Stroke Length Adjustment - The length of the shaker stroke is set at the factory
for a 1" stroke. The following procedure should be observed when changing
stroke lengths.
Warning Turn OFF power to the bath and disconnect the bath from its power
