General Care and Maintenance
• To remove the safety lid, push thumbs down on
the plastic lugs and lift the lid vertically with
your fingers.
• Before use, clean and dry the apparatus with
DISTILLED WATER ONLY.
• Before use, and then on a monthly basis, check
the unit for any leaks at the bonded joints. Place
the unit on a sheet of dry tissue and then fill with
DISTILLED WATER ONLY to the maximum fill line.
Any leakage will be seen on the tissue paper. If
any leakage is seen DO NOT ATTEMPT TO REPAIR
OR USE THE APPARATUS, but notify Hoefer
immediately.
• The replacement platinum electrodes are partially
shrouded for protection. However, when cleaning
the main tank DO NOT use cleaning brushes in
the electrode area. Usually a thorough rinse with
distilled water is all that is required.
• Ensure that the connectors are clean and dry before
usage or storage.
Storage of Water Cooled Units
We recommend complete drainage of cooling plate
coil units before storage. Store in a dark cupboard
or cold room.
Using the Cooling Platform
The Cooling Platform will already contain a small
quantity of water from control tests. The Cooling
Platform can be used in two ways. Static water can be
used as a simple heat sink or the tank can be actively
regulated using flowing water from a tap or water
bath/flow cooler.
IMPORTANT! Acrylic plastic
is NOT resistant to aromatic
or halogenated hydrocarbons,
ketones, esters, alcohol’s (over
25%) and acids (over 25%),
they will cause “crazing”
especially of the UV transparent
plastic and should NOT be
used for cleaning. DO NOT use
abrasive creams or scourers.
Dry components with clean
laboratory tissues prior to use.
