Davey Promatic ESC-pH SYSTEM Supplément Au Manuel page 3

INSTALLING THE PUMP MODULE:
IMPORTANT: KEEP BARE HANDS AWAY FROM POOL ACID AND ALWAYS USE
CAUTION WHEN HANDLING POOL CHEMICALS.
1. Refer general installation diagram on reverse of this page.
2. Select a convenient position within 2 metres of the ESCpH Control System, and 1.5
metres above ground level. Ensure chemical drum is placed as far away as possible from
the Control Unit and Pump Module to avoid corrosive damage. Control Unit and Pump
Module must be a minimum of 1.0 metre horizontally from drum.
3. Use the same mounting procedures as for the Control Unit. (Refer manual).
4. Connecting Pump Module to Control Unit.
Plug the mains lead from the pump module into the GPO in the bottom right of the unit.
5. Remove cap from drum and clean in water.
6. Drill a 9mm hole through the centre of cap. Fit the clear tube through the cap and then the
tube weight Push enough tube through the cap to allow the tube weight to sit at the
bottom of the drum.
7. Re - fit cap to acid drum.
8. Place chemical drum away from the Control Unit and Pump Module to avoid possible
corrosive damage from chemical vapour. Minimum distance horizontally between Pump
Module and Chemical Drum is 1.0 metres.
9. Using PVC cement fit Probe/Injector Housing to suction or return line (and ensure probe
is horizontal to the ground). NOTE: if return has a high backpressure use the suction line.
The Housing has 50mm standard fittings with reducers supplied for 40mm applications.
Ensure Housing is fitted with arrows pointing in the direction of water flow.
IMPORTANT: ENSURE SENSOR PROBE ALWAYS REMAINS MOIST.
RETURN VALVE MAY NEED TO BE FITTED IN POOL FILTRATION LINE TO STOP
DRAINAGE IN THE PLUMBING. SENSOR PROBE MAY BE DAMAGED BEYOND
REPAIR IF LEFT TO DRY OUT. WARRANTY WILL BE VOID IF THIS TYPE OF
DAMAGE IS APPARENT.
10. Remove cap from sensor probe, discard travel solution and screw into sensor housing.
Keep cap in a safe place for future sensor removal.
11. Connect wire from sensor probe to the connector on the base of the control unit. Ensure
water (garden sprayers, reticulation etc) does not splash or spray onto the connector. This
is likely to cause erroneous operation and may damage the sensor probe, voiding
warranty.
12. Fit Injector to Housing and connect the 6mm diameter clear tubes. Cut Clear tube can be
softened in hot water to enable easier connection. Tube may change colour and/or
become opaque in use.
13. Push tube onto barb connectors of dosing pump nearest arrows facing down and secure
with plastic clamps provided.
