Maintenance
Be careful especially of the following point before beginning maintenance
check.
1. Especially the maintenance work without directions of operation should surely
turn off the main power switch and take off the power cord for safety.
2. Warn to spill neither water nor a reagent to mechanism parts and electric parts.
Moreover, please place neither detergent nor medicine on equipment.
3. Please do not touch with a hand other than the appointed place.
● Routine maintenance work
1. Please clean a main part periodically and suitably.
2. Wipe all outside surfaces of the equipment with a diluted neutral detergent
solution.
3. When a liquid is spilt, please wipe off a sample block circumference part as
early as possible.
4. Since dust is easy to collect, please clean a sample block frequently. If dust
and garbage adhere to a sample block, a temperature control performance will
fall and temperature homogeneity will also become bad simultaneously.
5. Please check it that the air filters of the back of equipment, the left and
right-hand side is not closed. Please wipe off, when dust has adhered.
Neither strong alkali, high-concentration alcohol nor use of the organic
solvent can be performed. It becomes the cause of breakage, such as
discoloration, deterioration, and a crack.
