2.2 CONNECT THE STAGE TO THE CONTROLLER
Connect the two water tubes from the stage to the WATER connection on the front panel of the con-
troller. These tubes are interchangeable - the direction of flow is not important.
Connect the black, corrugated cable to the polarized POWER OUTPUT connector on the front panel.
Twist locking nut to lock connector to controller.
Insert blue thermocouple connector into the socket labelled SENSOR B - STAGE.
2.3 ATTACH THE STAGE TO THE MICROTOME
If the make and model of the microtome were specified with the order, the freezing stage should have
been shipped with the correct mounting hardware already in place. The most frequently used hardware is
a 3/4” vise block. Other pillar and blocks are available as well as adaptor plates for many brands and
models of microtome.
2.4 ATTACH AC LINE CORD
BEFORE CONNECTING CONTROLLER TO AC POWER SUPPLY,
CHECK SETTING OF THE VOLTAGE REGULATOR MODULE.
This module is on the back panel, bottom left. There are four setting; 100 for unusually low power situa-
tions, 120V, 220V and 240V. Confirm that the selector is set for your requirements.
Slide clear plastic panel to the left. If correct voltage is not visible in card, card must be pulled out and
replaced so that correct voltage is visible.
To change the position of the card, eject fuse by pulling on the FUSE PULL lever. Pull card forward,
reposition as necessary and reinsert.
Replace fuse and slide plastic cover back to the right.
Attach line cord to the controller.
2.5 TURN ON WATER SUPPLY
When all parts are connected, water can be turned on. Water supply should be adjusted until it flows
steadily, without spurting.
2.6 CONNECTION TO AC POWER SUPPLY AND “SWITCH ON”
Do not switch on unless water is circulating properly
Switch SENSOR INPUT to B position.
Connect AC line cord from controller to AC outlet and turn controller ON.
The power indicator on the front of the controller will illuminate. IF LAMP FAILS TO LIGHT,
SWITCH OFF AND CHECK FUSES.
