Ensure that the instrument is switched OFF.
Open the wash bottle cap (Fig. 6.1) very carefully to release any
residual pressure. Let the hissing sound end prior to opening the cap
all the way. Fill the wash bottle with appropriate washing reagent and
tighten the bottle cap firmly (Fig. 5.12).
Select either one of the preprogrammed wash cards or the
programmable switch card (Section 6.5).
Before inserting any program card, ensure that it is clean and dry.
Wiping the surfaces with a soft dry cloth will suffice. If any liquid is
present on the card, a malfunction of the program may occur.
Position the plate carrier on its slideway with the priming reservoir to
the rear under the wash head (see Fig. 5.13).
The POWER indicator on the keypad (Fig. 4.2) illuminates and a
countdown sequence will begin on the row indicator LEDs.
The PRIME indicator flashes until you prime the system.
The priming function is complete when the PRIME indicator turns OFF.
If no further key entry is made within fifteen seconds of priming, then
the pump will automatically switch OFF. The instrument will then enter
the idle state, waiting for instructions from the keypad and program
card.
Check that the correct wash head (8-way or 12-way) is fitted.
Check that the plate is placed properly onto the plate carrier (Fig. 5.16).
Select the row number of the last row to be washed. If no row is
selected, the whole plate will be washed.
The instrument performs the wash sequence.
