Fitting the communications lead
Connect the communications lead from the heating circulator to the refrigerated bath.
The connecting ports are shown in Section 4.2 and figures 2 to 4. This enables the
heating circulator to control the cooling power. If the lead is not connected correctly the
heating circulator will display the fault

Electrical supply
Connect the equipment to a grounded (earthed) electrical power supply with
voltage and frequency within the range specified on the serial number plate.
The equipment must only be connected to the mains using the mains cord
supplied or one with an identical rating (see section 9.4)
Ensure the mains switch and isolating device (power supply connector) is
easily accessible during use.
The method of connection of 230V equipment and 120V equipment differs: on 230V
equipment, the heating circulator is supplied with mains power via a link cable from the
refrigerated bath; on 120V equipment, the heating circulator has its own permanently
attached power cable with a NEMA 5-15P plug suitable for North American outlets.
230 V equipment
Connect the heating circulator using the mains link cable by plugging it into the “Mains
power inlet” on the heating circulator (see figure 2) and the “mains outlet for heating
circulator
” on the refrigerated bath (see figure 4). Connect the equipment to the mains
supply by plugging the mains supply lead into the “Mains power cable inlet” on the
refrigerated bath (see figure 4) and a suitable mains power outlet in the building.
CAUTION: Take care not to plug the heating circulator into the
“mains outlet for
accessory pump” (see figure 4) as this will blow the replaceable accessory pump fuse. It
won’t cause any further damage, but it will cause inconvenience.
120V equipment
Connect the heating circulator by plugging its fixed cord-set into a suitable mains power
outlet in the building. Connect the refrigerated bath to the mains supply by plugging the
mains supply lead into the “Mains power cable inlet” on the refrigerated bath (see figure
5) and a suitable mains power outlet in the building.
CAUTION: this equipment is designed to be connected to wall outlets with branch circuit
protection. Use only the supplied mains cords or identical replacements. The heating
circulator mains cord is not replaceable by the user (see section 9.4).
