MAINTENANCE & REPAIR
5.1 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.
5.2 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.
5.3 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 re-using (the process
usually takes 24 hrs).
E. Please ensure that the cabinet door remains open during this
process.
