Foot filter
When forming the plumbing connections, follow these instructions:
−
The
FOOT FILTER
must be installed in such a way that it is always 5-10 cm from the bottom to prevent any
deposits clogging it and damaging the hydraulic part of the pump.
−
Installing the pump under a head is always best and is recommended for pumps with a very low flow rate as it
solves all priming problems.
Installation under a head is specifically recommended when dosing
sodium hypochlorite (NaOCl) and hydrazine (N
2
H
2
) or any other product that tends to develop gas.
−
Pumps are supplied standard with entry and exit pipes that are sized to suit the pump’s hydraulic
characteristics. Should you need to use longer pipes, it is important to use pipes with the same internal and
outside diameter as those supplied with the pump.
−
For outdoor applications, where the
DELIVERY PIPE
may be exposed to direct sunlight, we recommend
using black piping that is resistant to ultraviolet rays.
−
It is advisable to position the
INJECTION POINT
towards the top of the pump or the tank. In all cases, to
guarantee the pump’s performance, always use the
INJECTION VALVE
supplied with the pump.
−
THE INJECTION VALVE MUST ALWAYS BE INSTALLED AT THE END OF THE DELIVERY LINE FOR
THE DOSAGE FLOW.
