Ventilation; Electrical Requirements - Thermo Scientific STANDARD Series Instructions Manual

Section 3 Installation

Ventilation

All circulators except A45HC can operate with 0 clearance on two exhaust
sides as long as the third exhaust side has unrestricted air flow. A45HC must
have at least 25mm [1"] of clearance on both sides to comply with UL leak
mitigation safety standards. Blocked ventilation will increase the circulator's
temperature, reduce its cooling capacity and, on refrigerated baths, eventually
lead to premature compressor failure.

Electrical
The circulator's construction provides protection against the risk of
electrical shock by grounding appropriate metal parts. The protection
Requirements
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.

For Sahara baths, and stand-alone immersion circulators, use the
supplied nut and washer to secure the grounding strap to the top of
the metal tank. See previous page.

The circulator is intended for use on a dedicated outlet. All circulator are
equipped with automatic thermally-triggered 20 Amp circuit protector.
The circuit protector is designed to protect the circulator.
Note If the circuit protector activates allow the circulator to cool before
resetting. Restart the circulator. Contact us if it activates again.

The circulator's power cord is used as the disconnecting device, it
must be easily accessible at all times.

Operate the circulator using only the supplied line cords, never operate
equipment with damaged cords.

Refer to the bath nameplate on the rear, upper-left-hand corner of the
bath for specific electrical requirements. Voltage deviations of ± 10%
are permissible. The outlet must be rated as suitable for the total power
consumption of the circulator, see next page.
Note If a bath and immersion circulator were purchased separately, follow
the electrical requirements listed on the bath nameplate.
