Important information
• The safety lid must be in place before connecting
the power leads to a power supply.
• Turn all power supply controls off and disconnect
the power leads before removing the safety lid.
• Before the first use, fill the base with about 600 ml
50/50 ethylene glycol/water to prevent irreparable
damage to the unit. (See instructions on page
4.) The base must be filled even if no cooling is
required.
• Do not use pure water, commercial anti-freeze, or
any organic solvent to fill the base. Water expands
as it freezes. Because the water is trapped in the
base, it may crack. Organic solvents will cause
irreparable chemical damage to the unit!
• Do not chill the base below -20 °C (-4 °F). Chill the
base in a bucket of ice, refrigerator, or in a freezer.
• Do not operate with gel or buffer temperature above
50 °C. Prevent overheating by chilling the base prior
to use. To prevent overheating during prolonged
high-voltage runs, exchange the first base with an
extra prechilled second base if one is available.
Overheating will cause irreparable damage to the
unit!
