For refrigerated baths: Ensure all communication and electrical connections are made prior to starting the unit.
Install the supplied RJ45 shielded cable between the immersion circulator and the bath RJ45 connectors (similar to Ethernet). This is required for proper operation. Install the power cord from the connector on the rear of the controller, A, to the connector on the rear of the refrigerated bath, B. Connect the bath’s power cord, C, to a grounded power outlet.
For refrigerated baths, never connect controller power inlet, A, to a power outlet. Never connect power outlet, B, to anything but an immersion circulator. Ensure the electrical cords do not come in contact with any of the plumbing connections or tubing.

Requirements
The unit construction provides protection against the risk of electrical
shock by grounding appropriate metal parts. The protection will not
function unless the power cord is connected to a properly grounded
outlet. It is the user's responsibility to assure a proper ground
connection is provided. 
The unit is intended for use on a dedicated outlet. All units are equipped with
automatic thermally-triggered 20 Amp circuit protector.
NOTE If the circuit protector activates allow the unit to cool before
resetting. Restart the unit. Contact us if it activates again. 
The circuit protection is designed to protect the controller, and is not
intended as a substitute for branch circuit protection. Position the unit so it is
not difcult to operate the disconnecting device.
If the unit's power cord is used as the disconnecting device, it must be
easily accessible at all times. 
Refer to the bath nameplate on the rear, upper-left-hand corner of the
bath for specic electrical requirements. Voltage deviations of ± 10%
are permissible. The outlet must be rated as suitable for the total power
consumption of the unit, see next page.
NOTE If a bath and immersion circulator were purchased separately, follow
the electrical requirements listed on the bath nameplate. 
DANGER
Ventilation
CAUTION
The unit can operate with 0 clearance on two exhaust sides as long as the
third exhaust side has unrestricted air ow. Blocked ventilation will increase
the unit's temperature, reduce its cooling capacity and, on refrigerated units,
eventually lead to premature compressor failure.
