MAINTENANCE & REPAIR
4.1 EQUIPMENT RATINGS
220/240V AC, 50 Hz. Up to 11 amps max. (see rating plate for details). The
cooled incubator is designed to operate in an environment from +10ºC to 30ºC
with a relative humidity from 5 - 85% RH non-condensing. Correct
functionality of the cooled incubator or its safety features cannot be guaranteed
if it is used outside these ratings.
4.2 REPLACEMENT OF FLUORESCENT LAMPS (WHEN FITTED)
This must be carried out with the mains power switched off and by a
competent person or engineer. Replacement lamps must be of the same size,
wattage and voltage as originals.
4.3 ROUTINE MAINTENANCE
It is recommended that the cooled incubator be inspected annually by a
competent service engineer. The exterior and interior surfaces can be
maintained in as new condition using standard non-abrasive or non-corrosive
cleaners. Solvent based cleaners must not be used. Switch off during all
cleaning operations. Allow drying before switching on. On Series 3 and 4
cabinets, the condenser should be brushed clean every six months.
A complete defrost is recommended periodically depending on application
To effect a defrost complete the following: -
A. Switch off the cooled incubator at the mains switch.
B. Allow the cooled incubator’s interior to attain ambient temperature by
opening the door.
C. If necessary, to speed up defrosting, start a heating cycle by setting the
temperature to 35ºC and turning the refrigeration off.
D. Allow the cabinet to completely dry-out inside before reusing (the
process usually takes 24 hrs). Please ensure that the cabinet door
remains open during this process.
