REPLACING A SAMM BLOCK
Switch off the mains supply to the monitor
and wait for a few seconds while the power
supply discharges. Open the enclosure door
with the key provided and switch off at the
internal power input module using the red
button
(1) .
Disconnect the hose from the faulty SAMM
block
(2) leaving the white non-return valve
connected to the SAMM block. Unplug the
SAMM block wiring connector
(3) .
Remove the four fixing screws (4) that hold
the faulty SAMM block to the base of the
enclosure, being careful not to damage the
gasket between the SAMM and the inside of
the enclosure.
To install the new SAMM block, fit the new SAMM block in the vacant position. (Note: It will only fit
with the 8 short sampling pipes facing towards the front of the enclosure.) Fit the shake-proof
washers and fixing screws and tighten. Re-attach the hose to the non-return valve of the new SAMM
block and plug in the SAMM block wiring connector.
If you are wiring the new SAMM block directly to the network module for pump 5-8, 9-12 or 13-16,
then you must connect the wiring for the new SAMM block pump marked 1 to the far left pair of
terminals on the associated network module connector and the wiring for pump 2 to the next pair of
terminals to the right and so on.
Switch on at the internal power input module using the green button. Close and lock the enclosure
door and reinstate the mains supply.
