INSTALLATION INSTRUCTIONS
These instructions apply to both Filters and Softeners.
If
a
Softener,
Softener/
Purifier or Carbon unit is to be
installed in an area where there
is sediment,it is advisable
to install a sediment filter to
keep the media bed clean
and prevent the jamming of
the solenoid valves on the
automatic units.
Check the size of the house.
Larger houses generally have
2 or 3 showers/ bathrooms,
automatic dishwashers and
washing machines and have
20mm (3/ 4”) or 25mm (1”)
pipe supply. This is to ensure
adequate flow rate if two or
more units are in operation at
any one time. Unit selection
must therefore be based on
flow rates and capacity, to
prevent pressure/ flow loss.
CHECKLIST
The unit should be installed:
a) ON a firm level, i.e. a cement path or pre-cast slab.
b) Within three metres of a gully trap or sink. If the distance is greater, the drain pipe size must
be increased to 20mm.
c) Do not supply treated water to the garden taps.
Pressure requirements – Maximum 825 kPa (120 psi) Minimum 275 kPa (40 psi).
a) If the available pressure is lower than 275 kPa the water softener’s A10 valve will not be able
to function properly.
b) If the pressure is above 825 kPa (120psi), fit a pressure limiting valve. A pressure limiting valve
is also recommended if your area is subject to high pressure fluctuations and/ or it is a
requirement of your local Water Authority.
The transformers used on automatic units are not suitable for external installation and should be installed inside or pro-
tected by a weatherproof shroud.
NOTE : In multiple installations, filters are always installed upstream of softeners.
!
CAUTION
CONNECTIONS
Each unit has 3 connections; drain inlet and outlet. These will be 15mm or 25mm, depending on the model
selected.
1) Fit an isolation valve to the inlet supply. This can be in the form of an approved gate valve or ball valve.
2) Connect inlet (top) & outlet (bottom).
3) Connect drain line to either the timer (semi-auto) or to the solenoid (fully auto), using 15mm flexible hose and
run to drain. Leave a 75mm gap between end of drain line and the drain for observation of flow.
4) If the drain is more than 3 metres from the unit, the drain hose size must be increased to 20mm.
5) Connect overflow hose (supplied). Do not interconnect overflow line with drain line, run as a separate and also
leave a 25mm gap. NB Filters do not have an overflow.
6) All softeners have a cabinet overflow, which should be connected to the drain with a flexible hose.
7) If the unit is a softener, load one or two 25kg bags of Commandomatic Water Softener Salt into the Brine Tank
to ensure the tanks is about two thirds full.
INITIAL OPERATION
If a Commandomatic Automatic Controller is fitted to the unit, please program the Controller before initial
operation of the unit, refer to “Programming the Controller ” .
a) For Filters
: Turn on the inlet valve. Start the Filter in the backwash cycle. When the vessel has
filled, there will be a continuous water flow to the drain. Allow the unit to backwash
for 15 minutes, the unit will then return to normal operation.
b) For Softeners
: Turn on the inlet valve. Start the Softener in the regeneration cycle. When the vessel
has filled, there will be a continuous water flow to the drain. As soon as this happens,
regeneration may be terminated, which will return your softener to normal operation.
Then salt may be loaded. Your softener has been factory regenerated and is ready for
immediate use.
