INSTRUCIONS FOR AUTHORIZED PERSONS ONLY
Before installation
The safety instructions must be read carefully before installation. You must definitely fulfil the requirements stated by the uwe
company and by the standard authorities. If the instructions are not observed, the installation engineer shall bear the sole respon-
sibility. The manufacturer shall thus be absolved of any liability.
See drawing 7 on the last folded page.
Mounting the nozzle assembly (picture number 8 red bronze version)
Moisten the gasket rings (1) of the nozzle assembly (2) and push the assembly into the wall fitting (30) until the front plate rests
against the tiles in the case of tiled/mosaic pools. Ensure that the countersunk holes on the nozzle assembly line up with the
threaded holes in the wall fitting. Insert the countersunk screws (3) and screw in without over tightening.
Repeat the above operation as necessary.
Mounting the intake screen and pump suction hose (picture number 8 red bronze version)
Centre the intake screen (4) on the wall fitting (5) in such a way that the threaded holes in the wall fitting are in line with the
countersunk holes of the intake screen. Insert countersunk screws (6) without over tightening.
Screw both stainless steel screw plugs (7) and washers (8) from the outer side of the pool into the threaded holes (9) if necessary
and seal with PTFE tape or similar sealing material.
Do not forget to insert gasket (16)
Connect the nipple (10), gate valve (11), 90 degree elbow (12) and suction hose (13) to the wall fitting with PTFE tape or similar
sealing material.
The plastic suction and pressure hose connectors should be connected tothe plastic pumpcasing (18/24), first ensuring that the
fibre washers (16) are in place. The plastic connecting nuts should be started by hand, and gently tightened using a strap wrench.
Tightening by means of a metal Stillson type wrench is not advised as it is likely to cause the nuts to fracture.
The pump requires a flooded suction and should be installed in a chamber or walkway behind the pool wall. The chamber must be
dry, drained and ventilated. The motor must be protected against flooding by a suitably sized floor drain, or in cases of high water
table by a float operated submersible pump.
If the pump is to be installed on a console/mounting bracket, supplied as an optional extra, the console should be fitted to the back
of the pool wall beforehand with concrete wall fixings. The pump should be secured with anti vibration mountings.
Alternatively the pump should be secured with appropriate fixing on a concrete plinth (20 cm x 20 cm, minimum height 10 cm).
The 90 degree special pipe-bend (12) features a threaded 1/2" pipe connection, which is sealed by means of a screw plug (19).
This pipe connection may if required be linked with the delivery side of the swimming pool filter by means of a 1/2" or 1" plastic pipe.
The advantage of this is that the lines of the jet system may if necessary be flushed through.
Pipework on the discharge side (picture number 8 red bronze version)
Insert nipple (20), gate valve (21), ‘T’ connector (22) to rear of wall fitting (30) nearest to pump. Into the end of the delivery hoses
(23) insert brass hose connector (17), secure clamps and connect to ‘T’ connector (22) inserting fibre washer (16) before tighte-
ning.
Into the opposite end of the delivery hose insert plastic hose connector and nut (17) and clamps having first cut hose to required
length. Ensure that fibre washer (16) is in place and connect to plastic pump delivery port (14).
To facilitate entry of connectors into plastic hose (23), hose ends may be softened using hot air or by dipping into very hot water.
Insert nipple (20), gate valve (21), ‘T’ connector (22) to rear of wall fitting (30) furthest from pump, attach blanking cap and washer
(26) to spare leg of ‘T’ connector (22).
Into the end of the connecting delivery hose (25) insert brass hose connector and nut (17), secure clamps and connect to ‘T’
connector (22) inserting fibre washer (16) before tightening.
Into the opposite end of the connecting delivery hose insert brass hose connector and nut (17) and clamps having first cut hose to
required length. Ensure that fibrewasher (16) is in place and connect to ‘T’ connector.
Repeat operations for additional wall fittings as necessary.
Installing the air inlet fittings (picture number 8 red bronze version)
It is advisable to make provision for protecting the pneumatic tube (PVC 2/4 Dia.) and air inlet tubes (PVC 12/21 Dia.) by placing
in protective conduit or through adjacent cable/ventilation ducts. Insert and tighten the threaded straight hose connector (27) with
washer (29) into the threaded apertures in the back of the wall fitting (30). This operation applies to all wall fittings.
The air inlet fittings (33) consist of a ball type non return valve with a straight connector, pipe clamp and fixing clip (32).
The air inlet fittings (33) should be located behind the pool wall with its opening at least 5 cm above the maximum water level of the
pool, away from the pump chamber to avoid any possibility of flooding.
The 4 m lengths of air inlet tube (PVC 12/21 ) may be shortened if necessary. The shorter the tube, the lesser the resistance, and
the higher the volume of air flow. It is advisable to thread the air inlet tubes through protective sleeving.
Steps should be taken to ensure that builders debris does not enter the tube or valve during the course of construction. The
purpose of the non return valve is to prevent water spraying out of the air inlet fitting. The valve will only function properly as long
as no hair/debris or lime deposit accumulates within it.
Fit the supplied air inlets to the end of the air suction hose. Push the hose nipple of the valve (33) into the hose and secure by
means of the hose clamps. Fasten the pipe clip (32) with screw supplied to an adjacent wall. This should be repeated for remaining
fittings.
