2. 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.

• Circulate only water or 50/50 water/ethylene glycol

through the heat exchanger. Never introduce anti-
freeze or any organic solvent into any part of the
instrument. Organic solvents will cause irreparable
damage to the unit!

• Do not connect the heat exchanger to a water tap

or any coolant source where the water pressure is
unregulated.

• Do not operate with buffer temperature above 45

°C. All plastic parts are rated for 45 °C continuous
duty. Circulate coolant through the heat exchanger
during electrophoresis to minimize heating. Addi-
tional passive cooling actions include chilling the
buffer before use, running the unit in a cold room,
or both. Overheating will cause irreparable damage
to the unit!

• If running only one gel, block off the unused part

of the core with a glass plate. Do not ﬁll this side
with buffer.

• Only accessories and parts approved or supplied by

Hoefer, Inc. may be used for operating, maintaining,
and servicing this product.
