Routine Cleaning And Maintenance
To maintain the Immersion Heater Circulator in good, safe working order and ensure maximum product lifespan, regular cleaning and
general maintenance is required. The Immersion Heater Circulator should be cleaned at least once every month for a unit being used on
a daily basis, for infrequently used Immersion Heater Circulators a cleaning frequency of once every 3 months 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
CAUTION
If the Immersion Heater Circulator 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 Immersion Heater Circulator element is cold before
cleaning.
Allow the Immersion Heater Circulator to cool for at least 10 minutes after it has last been operated prior to
starting the cleaning procedure.
CAUTION
Do not use abrasive cleaners or solvents on the Immersion Heater Circulator 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 or laboratory sterilization agent when cleaning the Immersion Heater Circulator.
CAUTION
If the Immersion Heater Circulator has been used with any dangerous, chemical or biological substances it should be
decontaminated prior to cleaning. Decontaminate the Immersion Heater Circulator 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 Immersion Heater Circulator 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 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 Immersion Heater Circulator 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 Immersion Heater Circulator 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 Mains Power Switch
-
Unplug the equipment from the mains power supply outlet.
-
Using a mild detergent and damp sponge, clean around the element and circulator being careful not to knock the
over-temperature safety capillary bulb which is clipped to the element. Pay particular attention to any loose
particles that may lead to or accelerate corrosion.
