5.2.2. Electrical
There are no user-serviceable parts in the AC transformer, motor, or controller. In the event of a
failure, these should be replaced.
•
All electrical connections must be completed according to local codes.
•
Use only the power AC transformer that is supplied.
Mandatory
The use of any other power transformer than the one supplied void the warranty of all
electronic parts of the valve.
•
The power outlet must be grounded.
•
To disconnect power, unplug the AC transformer from its power source.
•
An uninterrupted current supply is required. Please make sure that the voltage supply is
compatible with the unit before installation.
•
Make sure the controller power source is plugged in.
•
If the electrical cable is damaged, it must imperatively be replaced by qualified personnel.
5.2.3. Mechanical
•
Do not use petroleum-based lubricants such as vaseline, oils, or hydrocarbon-based lubricants.
Use only 100% silicone lubricants.
•
All plastic connections should be hand tightened. PTFE (plumber’s tape) may be used on
connections that do not use an O-ring seal. Do not use pliers or pipe wrenches.
•
All plumbing must be completed according to local codes.
•
Soldering near the drain line should be done before connecting the drain line to the valve.
Excessive heat will cause interior damage to the valve.
•
Observe the drain line requirements:
Maximum 1 m high at 2 bars inlet pressure. Add 50 cm for each additional 1 bar inlet pressure.
•
Do not use lead-based solder for sweat solder connections.
•
The drain line must be a minimum of 12.7 mm (½") in diameter. Use 19 mm (¾") pipe if the
backwash flow rate is greater than 26.5 lpm (5.83 gpm) or the pipe length is greater than 6 m.
•
Do not support the weight of the system on the control valve fittings, plumbing, or the bypass.
•
It is not recommended to use sealants on the threads. Use PTFE (plumber’s tape) on the threads
of the drain elbow, the drain line connections, and other NPT/BSP threads.
