4.0 SETTING UP
4.1 Electrical Hookup
The power (off/on) switch, fuse tray, and power cord receptacle are located on the rear of
the Geno/Grinder cabinet, toward its bottom. The detachable power cord should be
plugged firmly into its inlet, then into an electrical outlet. Make sure that the electrical
outlet is easily accessible in case it becomes necessary to unplug the unit. For 115V/60HZ
use, a 3-prong outlet fused at 20 amps is recommended. The 230V/50HZ Geno/Grinder
power cord has a standard European 2-prong plug, but modification by the user may be
necessary to meet local electrical codes.
4.2 Cabinet Set-Up
To open the cabinet, grasp the handle and raise the top cover to its full upright position.
The gas spring will hold the cover in its open position. To close, grasp the handle and
carefully lower the cover until it is fully closed.
A safety interlock will engage the Geno/Grinder only when the top cover is closed. If the
START button is pressed while the cover is open, the Geno/Grinder will not start. Similarly,
if the cover is opened during operation, the safety interlock will disengage, the motor will
immediately stop, and movement of the clamp assembly will cease.
4.3 Installing the Clamp Assembly
The Geno/Grinder is available with three clamp assembly options. The 2189 adjustable
clamp can accommodate a variety of titer plate and vial sizes. The standard 2194 clamp
assembly is designed to hold two standard deep-well titer plates. The optional 2199 large
clamp assembly holds four standard titer plates: two side by side, with two more stacked on
top. This clamp assembly also is used with 15 mL or 50 mL centrifuge tubes. The
Geno/Grinder clamp can also be adapted to hold anything with the same general
dimensions (5 in. long x 3 in. wide x 2 in. (or 4 in.) high). This includes titer plates with
fewer and/or larger wells, racks that hold multiple individual vials, and other possible
configurations. The 2194 and 2199 clamps are supplied with height adjustment spacers of
varying thickness to accommodate sample holders of differing heights. Spacers are not
required for the 2189 adjustable clamp.
To prevent damage during shipping, the clamp assembly is not installed at the factory.
Before operation, this must be installed by the user.
