5.0 Operating procedures
5.1
Operation
5.1.1 Water level
Ensure that the baths are used with the appropriate base tray and that the water always
covers the tray. The maximum water level should not be higher than the swage line
around the top of the bath or around 2.5cm from the top. These criteria apply both when
there are no vessels in the bath and with the maximum contents.
Avoid letting the bath run dry. In the event this does happen, the safety cutout will trip
and disconnect the heater. If this does happen, unplug the bath and have the cut-out re-
set by a competent person.
5.1.2 Operation above 60°C
The lid must be used above 60°C to maintain proper temperature control and to ensure
that the water temperature reaches the set point
The lid will also prevent excessive evaporation that requires the bath to be filled more
often and will save energy.
5.1.3 Flat bottomed vessels
Do not place flat-bottomed vessels or other objects directly on the bottom of the tank.
Always use the base tray. This avoids possible damage to the heater mounted under the
tank. The base tray also improves temperature control.
5.1.4 Emptying the baths
Before emptying any bath allow the water temperature to fall to a safe level and take
reasonable precautions to prevent accidental spillage.
Drain taps are included in 12L and above JB Aqua Plus and SUB Aqua Plus baths to
allow convenient emptying. These baths should be emptied using the drain tap prior to
moving.
To empty the bath using the drain tap, push the supplied drain insert into the drain tap
(see picture below). Note that the water will begin to empty as soon as the drain insert is
fully engaged. A length of hose can be added to the barbed end of the drain insert if
required.
