4.0 – TECHNICAL SPECIFICATION
Outer case and bath constructed in Type-304 stainless steel. The tank is fully insulated for greater
energy efficiency.
The water bath temperature is constantly monitored and controlled precisely within given parameters.
A pump is used to agitate the water and create a uniform temperature throughout the bath. The circuit
constantly monitors the operation of the appliance and warns the user via the CD display if any
abnormal circumstances have been detected.

5.0 – LOCATING THE BATH AND COMMISSIONING:
1). Place Water Bath on a smooth and level worktop capable of holding its weight when full of water
(refer to section-4 for weights).
IMPORTANT: Always ensure there is sufficient clear space above and around the bath, allowing the
hinged glass lid to be raised unhindered, into a fully open position (see diagram below):
CAUTION: Always take care and avoid knocking or bumping the edge or surface of the glass lid in
everyday use. Whilst the lid is made from toughened safety glass, its strength and integrity can become
compromised should it suffer from impact, which could lead to the lid eventually breaking/shattering. If
in any doubt, please contact Instanta technical department. Replacement glass lids are available from
Instanta spares department.
2) Use bath in a ventilated room (ambient room temperature 5°C to 35°C).
3) On initial commissioning, lift glass lid and make sure that the perforated baffle plate (in bottom of
bath) has not become dislodged in transit.
4) If required the stainless steel food rack (supplied) can be placed over the bath, resting on the edges
(portions of food can be suspended from the food rack using the clips provided).
Optional: If preferred, a set of stainless steel partition/divider plates are available (pt. no: SVP/4). These
can be used to divide the bath into compartments as described below:
Slide the perforated stainless steel partition-plates into the tank. With all four partitions used the bath is
divided into five sections, which correspond with the 5 timers on the control panel.
5) Fill water bath with mains cold water. As a minimum, the water level should cover the upper sensing
probe (situated in front of tank, above baffle plate). The maximum fill line is embossed into the back of
the tank-body.

6.0 - OPE ATING INST UCTIONS:
1) Once primed with water, plug bath into standard 13amp power socket and switch on by pressing
THE on/off button (front display panel). The CD display will illuminate and the bath will begin to heat
the water.
2) Set desired temperature by adjusting the temperature control knob (front panel). The temperature
can be adjusted in 0.1°C increments for extreme accuracy.
The CD display shows the “ACTUA ” Temperature of the water, and also the “SET” Temperature.
Once the water in the bath has reached the set temperature, the two readings will be the same.
3) The water within the bath can be “stirred” by pressing the “Agitation” button ( CD display shows
message: AGITATOR ON). This ensures temperature accuracy is uniform throughout the bath (Note:
Agitation does not operate when temperatures exceed 80°C).
4) Timer buttons:
The CD display has five individual timers (A, B, C, D, & E). As soon as these are pressed the time
counts upwards displaying “cooking time elapsed” thus allowing the chef to see at a glance exactly how
long a particular portion (or batch) of food has been in the bath.
The individual timer–buttons correspond with the labelled-rails on the food rack, allowing portions (or
batches of food) to be placed in the bath at different times. When a portion is suspended from a rail on
the food-rack, the corresponding timer should be activated. This ensures that all food, irrespective of
when it was placed in the bath, is accurately timed for perfect results.
To reset timers, press button twice and the CD readout will show 00.00 (zero).
NOTE: The timers will also correspond with up to five separate compartments within the bath (if optional
partition-plates (x4) are used).
IMPORTANT: Keep surface of glass lid clear and avoid placing frozen food or other items on top of it.
Do not dry damp cloths by placing them over the glass lid when bath is in use.
7.0 - IN DAILY USE:
Prime with water and switch on.
Set desired temperature.
8.0 - EMPTYING WATE BATH / CLEANING
The water bath can be drained-down and replenished with fresh water:
a) Unscrew chromed cover-cap from drain coupling (front of bath).
b) Attach drain hose (supplied), and direct hose into sink or bucket etc.
c) Turn drain-knob to “OPEN” to empty contents of bath.
d) When empty, REMEMBER to turn drain-knob to “C OSE” and disconnect drain hose from coupling.
e) Replace chromed cover-cap.
f) ift glass lid and fill bath with cold water to desired level.

CEANING:
If a vacuum sealed food bag bursts and soils the bath, it can be cleaned by draining down (as above),
and sterilising using a “Milton” solution or similar.
Outside surfaces of the appliance can be cleaned using a damp cloth. A suitable stainless steel cleaner
may be used on the stainless steel fabrication. Do not use abrasive cleaning products on the glass lid.
9.0 - DE-SCALING
To de-scale your water bath, first unplug the appliance from the power supply.
ift glass lid and remove partitions and perforated baffle plate.
Remove as much loose scale as possible by hand from the bottom of the bath. Any scale which is
difficult to remove can be dissolved by using a suitable de-scaling solution (available from Instanta
Spares Dept).
Replace perforated baffle plate and fill bath with water to maximum-fill level. Plug in and switch bath
on. Set temperature to 90°C and allow bath to heat water.
Once temperature has reached 90°C gradually stir in the de-scaling solution. eave for approximately
20 minutes to allow solution to dissolve the lime-scale (see de-scaler instructions). Once the solution
has finished working, open drain valve (as described in Section: 6) to remove contents.
Remember to close drain valve. Ensure all traces of de-scaler are removed by flushing bath with clean
cold water. Stubborn lime-scale on the level sensing probes can be removed using a non-metallic
scourer.
10.0 - DISPLAY WA NINGS
LOW WATE ! - There are two level sensors within the bath. When the water level drops below the
TOP sensor, the CD display flashes the message “ OW WATER!” and an audible bleep can be heard
approximately once every 60 seconds. This is a reminder to top-up the water level. In this condition,
the water bath will continue to operate as normal whilst displaying the warning.
If this is ignored and the water level within the bath reduces further, eventually the OWER sensor will
also become exposed. The CD display will continue to flash the message “ OW WATER!” but the
audible bleep will become more frequent, informing users that the water level in the bath has now
dropped to a critical state. In this condition, the heater is shut-down for safety.
As soon as sufficient water is added and the level within the bath increased to cover the two sensors,
any warnings are cleared and the water bath continues to operate as normal.
