5.1.7 Setting up and switching on
Follow instructions in section 5.1.4 to attach the pump connector plate and insulated
hose. Before filling and switching on, attach the open end of the hose to the application,
taking care to note the inlet and outlet.
Ensure all hoses are connected securely. Liquid will begin pumping
immediately once equipment is switched on.
Add the appropriate working liquid to the bath to at least the minimum recommended fill
level. See section 5.1.1
Refer to section 4.6 for the instructions for connecting the equipment to the mains supply.
For 230V equipment.
Make sure the heating circulator power switch is in the ON position.
For 120V equipment.
The refrigerated bath and heating circulator must be switched on separately. Note that
the refrigerated bath will not operate until the heating circulator has started up.
When working at high temperatures, ensure the cables are not touching hot surfaces or
air vents

model and the software version number. The equipment will now display the current
liquid temperature and start to heat or cool to reach the set point temperature.
5.1.8 Eco mode cooling
The equipment has variable power cooling as well as heating. This enables the
equipment to achieve and maintain the required temperature using minimum energy
without a loss in performance. The equipment is preset to run in this energy saving Eco
mode. The eco mode icon on the heating circulator display indicates when the equipment
is set to eco mode. The cooling can also be set to OFF or HIGH for continuous maximum
available power . See section 5.3.2 to configure the cooling mode.
