10. Maintenance and Service
No routine maintenance is required except for cleaning, there are no user serviceable parts
inside the CRF-1 unit.
Warning: Attempted disassembly could cause damage that could seriously affect the
operation of the unit and its ability to follow the desired temperature profile.
10.1. Cleaning
The freezer unit and sample plate is designed to be easily cleaned and sterilised. It is
important to use a cleaner which does not leave a residue and will not attack the sample plate
(chlorine based products must not be used).
We recommend the use of Klercide
™ Sporicidal Low Residue Peroxide (formerly known as
Premier Klercide
™ -CR Sterile Filtered Biocide C) which meets these requirements. Before
using any other cleaning or decontamination method, check with Grant Instruments to ensure
that the proposed method will not damage the equipment.
Side and rear vents should be kept clean and free of dust to ensure good ventilation.
If a potentially hazardous liquid is spilt onto the equipment, disconnect it from the power
supply and have it checked by a competent person. It is the
user’s responsibility to carry out
appropriate decontamination if hazardous material is spilt on the equipment.
