Pool Lab Add-on modules and accessories
Detailed installation instructions are included with the Pool Lab add-on modules and
accessories, please refer to these documents for more detailed information.
ASP
The power/data cord from the ASP connects to the Pool Lab Salt Chlorinator into the
socket labelled “ASP” and the peristaltic acid pump connects to the Pool Lab Salt
Chlorinator into the socket labelled “ACID PUMP”.
IMPORTANT NOTE: When installed on a pool and spa combination system, a SPA FLOW
SWITCH is required (sold separately, see below).
Please ensure the following system configuration items are set and correct before use:
– POOL VOLUME (default is 50,000 L)
– SPA VOLUME (default is 2,000 L – this can be safely ignored if there is no spa, and
no spa flow switch installed)
EXP
For all models except PL Hybrid (PL COMM and PL LT), the data cable from the EXP
connects to the Pool Lab Salt Chlorinator into the socket labeled “EXP”.
(For PL Hybrid systems see below)
The EXP module is fitted with a power lead which should be connected to constant power.
Pool or other equipment to be controlled by the EXP module should be plugged into the
outlet sockets at the bottom of the unit.
The water temperature sensor should be installed into the pipe on the filtration water
circuit, preferably before the filtration pump, and connected to the terminals labeled
“FILTER CIRCUIT TEMP SENSOR” in any polarity.
If controlling a solar system, the solar sensors (sold separately) will need to be installed
with the solar inlet sensor into the pipe on the inlet side of the solar array, and the roof
sensor mounted into a small piece of solar matting on the roof near to the solar sensor
array.
SPA FLOW SWITCH (Plus and MAX models only)
When installed on a pool and spa combination system, a SPA FLOW SWITCH is required
to prevent over-chlorination of the smaller volume of water when the spa is in use. This
switch must be installed on the SPA SUCTION line in the filtration circuit.
