OPERATION
INSTALLATION
1. Select the insert aluminium alloy block(s) appropriate for the application. A list of available blocks is
given on page 28 of this manual. Ensure that both the underside of the block(s) and the top of the
hotplate are clean; efficient heat conduction between these two surfaces is essential.

2. Place the insert blocks onto the hotplate in the well of the unit and place the tubes containing the
sample liquid in the blocks.
3. The heater design, temperature sensor and control circuit give good temperature control and
uniformity, but it is important that there is a close fit of the tubes in the block to allow efficient heat
transfer.
4. If less than the maximum number of insert blocks are fitted it is recommended that plastic half blocks
are fitted to the space either side of the aluminium block. The dummy blocks have the effect of
reducing heat loss, thus improving temperature stability.
5. Plug the mains cable into the socket in the rear of the unit. Connect to the mains electricity supply
with the plug provided or one wired correctly for your supply. Switch the power ON from the switch
located next to the mains input lead. The mains indicator on the front panel will light up (as well as
the fuse light on the mains input unit).
