10.2. MAINTENANCE OF THE PH PROBE
1.
The pH probe must be calibrated at least once per month. (For calibration procedure, see
chapter 9.3.3).
2.
Ensure that the membrane placed at the end of the pH probe remains always wet.
3.
For cleaning the probe, use fresh water and a soft cloth.
4.
If the probe is not going to be used for a long time, keep it submerged in a conservation
solution at pH 4.
5.
The pH probe is a consumable and it needs to be replaced periodically.
10.3. MAINTENANCE OF THE PERISTALTIC DOSING PUMP
Check periodically if the dosing pipes are leaking or have enough flexibility.
Check the foot valve inside the storage acid tank and clean it if necessary.
Check the injection valve in the circulation pipe and clean it if necessary.
11. WINTERIZING
During a period of low operation, such as winter, the procedures are as following:
a)
Minimum working operation
Activate WINTER MODE. The production of chlorine will drop at half.
If an automatic pool cover is installed and connected to the
SSC
one
®
unit, the system will
detect it and the production will drop the half again. So from the initial chlorine production,
now is reduced 75%.
Reduce the schedule time at minimum working period according to the aims of the pool in
winter season.
Check periodically the complete installation, the storage acid level and the electrolytic cell.
b)
Non-working period
If the installation is not working during a long period of time, the following recommendations have
to be carried out:
Switch off the
SSC
one
®
unit and disconnect it from the power supply.
Close the valves from the by-pass and remove the water from the cell.
Clean the cell plates with fresh water and dry them with a soft cloth. Check if scaling has
been formed. If scaling, proceed with the cleaning of the cell plates (see chapter 10.1).
Remove the pH probe and keep it submerged in a conservation solution at pH 4 in an
indoor place.
Remove the suction pipe of the dosing pump from the acid solution. Clean the dosing pipes
from the acid by dosing manually fresh water.
Clean the foot valve and the injection valve of the dosing pump with fresh water.
