Routine Cleaning And Maintenance
To maintain the water bath in good, safe working order and ensure maximum product lifespan, regular cleaning and general maintenance is required.
The water bath should be cleaned at least once every week for a unit being used on a daily basis, for infrequently used water baths a cleaning
frequency of once every month is recommended. On each occasion, the general maintenance routine should be employed following cleaning with the
exception of the over-temperature safety cutout test which need only be conducted every 2 years of normal operation.
Cleaning The Water Bath
CAUTION
If the water bath has been operated recently the heating element may be hot enough to create a hazard sufficient to burn or
scald if contact is made. Ensure the water bath is empty before cleaning.
Allow the water bath to cool for at least 20 minutes after it has last been operated prior to starting the cleaning
procedure.
CAUTION
Do not use alcohol based cleaners or solvents on the water bath as these may break down certain components of it’s
construction, reducing it’s life and potentially creating a hazardous situation. Use only a mild household detergent when cleaning
the water bath.
CAUTION
If the water bath has been used with any dangerous, chemical or biological substances it should be decontaminated prior to
cleaning. Decontaminate the water bath using a decontamination procedure appropriate to the contaminant, however in all cases
ensure the following :
-
No decontamination or cleaning agents are used which could cause a hazardous situation to arise as a result of a
reaction with parts of the water bath or with any materials contained in it. For example, substances that may
compromise the integrity or function of electrical insulation, electrical components, stainless steel components or water
seals.
-
Ratek and the manufacturer are consulted prior to decontamination or cleaning being undertaken if there is any doubt
about the compatibility of decontamination or cleaning agents with parts of the water bath or with any materials
contained in it.
CAUTION
When cleaning the unit, only use a damp sponge.
Do not use a sodden wet sponge.
Do not make any part of the control panel,
any exposed control or receptacle or any part of the water bath excessively wet. If these receptacles and controls remain wet
once electrical power is restored they can create a hazardous situation sufficient to cause serious injury or risk to life due to
electrical shock. Always ensure the unit and in particular all controls and switches are completely dry before restoring electrical
power.
-
Turn off the On/Off mains power switch (element 6 in Figure 1).
-
Unplug the equipment from the mains power supply outlet.
-
Empty all water from the water tank as per the section of this User Manual titled “Emptying The Water Tank”.
-
Allow the water bath to air dry, or use a dry cloth to remove water from all surfaces.
-
Remove the mesh platform.
-
Using a mild detergent and damp sponge, clean around the sides of the water tank as required. Pay particular attention to any
loose particles that may lead to or accelerate corrosion. Impurities out of your water supply may leave corrosive sediment
behind, it is
important to remove
these before returning the bath to operation. A soft dish scourer or metal polish (eg
Brasso) is generally sufficient for this purpose, be careful not to scratch the stainless steel of the water tank. The resulting
tank should be clean and clear with no visible brown spots or “halos” which are sediment particles sitting on top of the tank
surface. These particles can lead to corrosion if left unchecked.
