4 Installation notes
When you choose the site for your Pallas Duo, please take into account the following points and procedures:
1) To install your Pallas Duo in the chosen place, ensure that the floor is clean, flat and stable (If necessary, put a board under
the softener to ensure a level area ). There must always be a drain tundish adjacent to where the softener is to be installed to
allow the regeneration water to run-off. A power socket protected by a RSB and suitably earth bonded must be sited adjacent
to the softener.
2) In cold weather, it is recommended that the Pallas Duo is bought up to ambient temperature before proceeding with the
installation. The Pallas Duo must posititioned so that it is protected from freezing. Do not install the unit where it is exposed to
direct sunlight or high temperatures (45 °C max).
3) Plumbing must be installed according to the local bylaws and regulations in force. The size of the drain tube must be at least
13 mm (1/2").
4) The soldered joints on the principal plumbing and the connection to the drain pipe must be carried out before the Pallas Duo
is connected to prevent any damage to the softener. For all interventions, isolate the water supply at the stop cock and
disconnect the electrical supply.
5) Fill the salt reservoir with 50mm (2") water. Do not add salt for the moment.
6) Put the by-pass valve of your Pallas Duo in the "by-pass" position. Open the raw water feed tap and a cold water tap in the
vicinity run for a few minutes until all of the pipes are rinsed of any residual foreign bodies (solder remains). Turn off the raw
water feed tap and cold tap when water runs clear.
7) Put the by-pass valve in the "service" position and let the water run into the resin tanks. When the water flow stops, open a
cold water tap and let run in order to purge the air remaining in the resin tank. Repeat for the second resin tank.
8) Connect the softener electrically. Once powered, the valve may cycles itself and turn over the position service.
9) The valve includes an indicator to inform the fitter of its position: the wheel directly below the motor indicates the bottle
that is currently in the service position. The Digital display on the front of the softener alternates between the volume
remaining in the tank in service, the number of the tank in service (U-1 or 2 corresponds with the wheel: "INDICATION OF
the TANK IN SERVICE") and the time of the day.
Important: to understand various dislays, please see the following chapter: Programming.
10) Initiate a regeneration and bring the valve to cycle 1, by pressing the
regeneration button. The valve begins by
transfering from one tank to the other and then entering the regeneration cycle of the tank that was in service. The water runs
until the system is purged of the air. Once the air is completely evacuated, it enters the Brine draw & slow rinse stage and then
into brine refil. On return to the service position repeat the precedure. This allows the complete purge of the second bottle
.
11) The installation must be carried out under hygienic conditions. It is recomended that annual maintenance is
undertaken by qualified personnel.
