Pentair FLECK 5800 SXT - General Advice; Installation Instructions

3 - INSTALLATION INSTRUCTIONS
1. Install the softener pressure vessels in a chosen place on a
at rm surface.
2. During cold weather, it is recommended to bring the valve
back to room temperature before operating.
3. All plumbing for water inlet, distribution and drain lines
should be done correctly in accordance with legislation in
force at the time of installation.
4. The distribution tube should be cut ush with the top of the
tank. Slightly bevel the ridge in order to avoid deterioration
of the seal whilst tting the valve.
5. Lubricate the distribution tube joint and the joint with a
100% Silicon lubricant. Never use other types of greases
that may damage the valve.
6. All soldering on main plumbing and to the drain line should
be done before tting the valve. Failing to do so can
generate irreversible damages.
7. Use Teon® tape if necessary in order to seal between the
drain tting and the outlet ow control.
8. Ensure that the oor under the brine tank is clean and at
9. On units with by-pass, place in by-pass position. Turn on
the main water supply. Open a cold soft water tap nearby
and let run a few minutes or until the system is free from
foreign material (usually solder) that may have resulted
from the installation. Once clean, close the water tap.
10. Place the by-pass in service position and let water ow into
the mineral tank. When water ow stops, slowly open a cold
water tap nearby and let run until the air is purged from the
unit.
11. Plug the valve to a power source. Check that the valve is in
service position.
12. Fill approximately 25mm of water above the grid plate, (if
used). Otherwise, ll to the top of the air check in the brine
tank. Do not add salt to the brine tank at this time.
13. Initiate a manual regeneration, bring the valve into "brine
draw and slow rinse" position in order to draw water from
the brine tank until the blockage of the air-check valve ; the
water level will be approximately in the middle of the air
check. Open the cold water tap and let water ow in order
to drain the air out of the circuit.
14. Open a cold water tap and let the water run in order to drain
the air out of the circuit.
15. Put the valve in brine rell position and let it get back to
service position automatically.
16. Now you can add salt to the brine tank, the valve will
operate automatically.
2 - GENERAL ADVICE
1 WATER PRESSURE
A minimum of 1,4 bar of water pressure is required for the
regeneration valve to operate effectively. Do not exceed
8,5 bar; if you face this case, you should install a pressure
regulator upstream the system.
2 ELECTRICAL CONNECTION
An uninterrupted current supply is required. Please make
sure that your voltage supply is compatible with your unit
before installation. If the electrical cable is damaged, it must
imperatively be replaced by a qualied personal.
3 EXISTING PLUMBING
Existing plumbing should be in a good shape and free from
limescale. In doubt, it is preferable to replace it. The installation
of a pre lter is always advised.
4 BY-PASS
Always provide a by pass valve for the installation, if the unit is
not equipped with one.
5 WATER TEMPERATURE
Water temperature is not to exceed 43°C, and the unit cannot
be subjected to freezing conditions. (It could cause irreversible
damage to the valve).
