FIXING WALL OUTLET ELBOW - FOR CONCEALED SHOWERS ONLY :
Visio, Xia, and Lusso Wall Outlet Elbow
1. Decide on location of your elbow and plumb accordingly. Make good the wall with tiles etc.
2. Remove chrome cover and pull out brass insert, be careful not to loose the screws or the horseshoe
shaped retaining clip.
3. Screw brass insert into wall fixing using the two flats provided.
4. Push plastic sleeve into position and mark for screws.
5. Drill the wall, preferably using the two holes on either side of the plastic sleeve. This will ensure drilling
is as far away as possible, reducing the risk of cracked tiles.
6. Once screwed to the wall push on the plastic sleeve and fasten.
7. Slide the retaining clip into the two slots to clamp in position.
8. Slide chrome cover on to finish. At this point silicone can also be used to seal around the face of the cover
and wall.
SHOWER VALVE SERVICING/MAINTENANCE :
Please note - If your Pegler thermostatic shower fails to operate correctly upon installation or after a short
period of time, the following important points should be checked.
1. Check that the valve has been installed correctly in accordance with its particular feed system (see TYPES
OF INSTALLATION).
2. That the hot water temperature is adequate; the recommended minimum temperature is 60°C
3. Isolating the supplies and ensure that the filters are clean and that the check valves are free to move and
are unrestricted (i.e. Hot and Cold water are reaching the valve body)
COMMON PROBLEMS WITH PUMPED SYSTEMS:
1. Insufficient head pressure or flow to initiate pump. (Check for blockages in supply or at valve inlets)
2. Airlocks within the pump impellers. Any air bubbles formed by hot water will tend to cling to the top sur-
face of the pipe and dissipate to atmosphere through the vent pipe.
CARE AND MAINTENANCE:
To maintain the surface finishes, simply wipe occasionally with a mild detergent on soft damp cloth. Dry using
soft cloth, never use abrasive cleaners or chemical household cleaners, avoid contact with concentrated bleach.
Pegler products are manufactured to the highest standards and should require little or no maintenance. In
the unlikely event of any spare part being required, please visit our web site : www.pegler.co.uk , contact
your nearest stockist or the Pegler Technical Office on telephone number 0870 1200285
INTRODUCTION :
All Pegler thermostatic showers are designed to ensure a stable showering temperature during showering
even when other outlets in the system are being used e.g. washing machines. The products will also close
down in the event of cold-water failure reducing the risk of scalding. These products are also designed from
rugged engineering materials to give you years of trouble free service and are backed by the Pegler
Customcare Promise.
WATER BYLAW REQUIREMENTS :
It is important to ensure that the water supplies to your shower are connected in accordance with the water
regulations (WRAS) requirements and good plumbing practice. It is Pegler’s recommendation and good plumb-
ing practice that the supplies of hot and cold water to the shower valve should be equal (balanced) pressure in
order to provide a consistent flow. Supplies should be from a common source, either mains or tank fed. If sup-
plies are not equal pressures then a Non Return Valve (Pegler 801 Non Return Valve) should be fitted.
BYLAW 17 (2) B
The shower head of any shower hose pipe should be fitted with a fixed or sliding attachment so that it can
only be discharged at a point not less that 25mm above the spill-over level of the bath tray or fixed appliance.
BYLAW 30 (2)
Where the shower valve is supplied with hot water from a storage cistern and cold water from the mains
supply pipe a cold storage cistern that complies to bylaw 30 (2) must be used.
WATER SUPPLY OPERATING PRESSURES :
Pegler thermostatic shower fittings have been designed to function under the following conditions:
Maximum static water 10 bar
Minimum flowing water pressure 0.1 bar
Optimum operation pressures 0.1 to 5 bar
Maximum hot supply temperature 90°C - Recommended maximum hot supply 65°C
Minimum hot supply temperature 55°C, optimum 55°C to 70°C
NOTE : Operating pressure (on hot and cold line) should be kept as balanced as possible in order
to assure maximum efficiency. When the supply is higher than 5 Bar a Pressure Reducing Valve should be
fitted before the shower valve.( Pegler PRV-2). Flush out supply pipes before fitting the valve, as debris will
prevent the shower working to its optimum level. To prevent debris damaging the mixers we recommend
that you fit the filters provided. Your Pegler thermostatic shower has been designed to give you years of
trouble free showering. However it may require servicing from time to time to retain optimum perform-
ance. Therefore we recommend the fitting in-line of valves upstream of the valve to allow for servicing of
the shower. Please note on a concealed thermostatic shower elbows are supplied that include isolating
valves. For exposed showers we recommend the purchase of Pegler 808 (order code 523007) Any standard
sealant may be used on this product in accordance with the manufactures recommendations.

MAXIMUM TEMPERATURE SETTING :
There are two ways of adjusting the temperature. The first is to switch off the water supply preferably using
the recommended isolating valves fitted either upstream on an exposed valve or fitted on the inlet elbows
of the concealed valve. This will enable the use of water to other outlets in the system. Continue by remov-
ing the handle then adjusting temperature, switching the water back on and testing. This method can how-
ever become tedious as it may be done a number of times until the correct temperature reached.
Alternatively the temperature can be adjusted while the water is flowing; however this option means that a
jet of water will be spraying from the valve body while the temperature is being adjusted, take adequate pre-
cautions to limit the spray of water. Pegler would not recommend this process due to uncontrolled hot
water being dispersed.
1. Decide on which option you will be using to adjust the temperature.
2. Remove handle.
a. For Visio and Xia simple pull handle directly off. Once the handle is off remove screw and pull off brass
handle adaptor. Please note do not lose splined white plastic adaptor.
b. For Lusso unscrew Satin plated indice and remove screw to release handle. Once the handle is off
remove by pulling off brass handle adaptor.
3. Unscrew brass plug using a flat screwdriver. Remove ‘o’ ring inside spindle and keep safe.
4. Please note - at this point the valve may weep of water for a short period of time as it drains the water
from the pipe work. The amount of water will vary on installation due to the location and position of the
isolation valve.
5. Using a 4mm A/F size Allen key position down the
hole central in the valve until you reach the Allen
screw. Locate and turn anti-clockwise to increase
the temperature and clockwise to decrease.
6. Place ‘o’ ring on to the collar at the base of the brass
plug and reassemble back into the valve. This cannot
be over tightened.
7. Loosely reposition handle adaptor on the valve
ensuring that the stop [pip normally positioned at the bottom of the brass castellated ring] is aligned with
the cut-a-way on the underside of the handle adaptor. See right.
8. Reassemble the handle onto the handle adaptor using the reverse directions to those in point 2
9. Carefully operate the valve via the handle to ensure the correct showering temperature has been
achieved.

TYPES OF INSTALLATION :
There are a number of basic types of installation detailed below. If you are unsure as to your circumstances
please call us on 0870 1200285. To accommodate for these variations we enclose in your packing kit a num-
ber of flow limiters, check valves and filters. Having established your site installations see table below to
determine which, if any, flow limiters have to be fitted.

Please note for exposed thermostatic shower -
When using any of the flow limiters they must
be installed in the inlet of the elbow before the
check valve is inserted. Please ensure that the
restrictors are firmly located in position. In all
types of installation the minimum requirement
is that the filter and check valves are fitted.
Please note for concealed thermostatic shower – When
using any of the flow limiters they must be installed in the out-
let of the elbow after the filters. Fit into carrier before fasten-
ing to the loose nut. In all types of installation the minimum
requirement is that the filter, restrictor carrier and check
valves are fitted. The carrier for the restrictors is required to
hold the filter in place and should therefore still be used even
if no restrictor is.

MOUNTING - EXPOSED THERMOSTATIC SHOWER :
1. Use the backplate as a template for the fixing holes.
2. Drill and plug the wall to suit screws provided.
3. Secure backplate to the wall.
4. Flush out pipe work before connecting the valve.
5. Locate valve body onto the backplate and lock in position with the 4 grub screws provided.
6. Please note - Before connecting the inlet pipes you must read "TYPES OF INSTALLATION" to ensure
correct restrictors and filters are fitted.
7. Connect inlet pipes to the valve using the compression fittings on the elbows. Ensure the two lose flanges
are used to cover over the holes in the tiles around the exposed pipes.
8. Check joints are watertight.
9. Push in the four chrome plugs into the body holes.
MOUNTING - CONCEALED THERMOSTATIC SHOWER :
1. Flush out pipe work before connecting the valve.
2. Screw in the four mounting pins provided, into the four holes located on the diameter of the valve at the
rear end of the body. The holes in the pins should be then aligned parallel with the body.
3. Locate the valve in position and mark the holes of the mounting pins for drilling.
4. Drill and plug the wall and secure the valve body in position with the four screws provided. (Depending
on pipe layout/access it could be beneficial to connect the inlet pipes before securing the valve in the wall)
5. Please note - Before connecting the inlet pipes you must read "TYPES OF INSTALLATION" to ensure
correct restrictors and filters are fitted.
6. Connect elbows to inlet nut using the ‘o’ ring to seal. Both elbow and seal are supplied lose.
7. Connect inlet pipes to valve elbows with compression fittings.
8. Ensure isolating valves in elbows are open.
9. Check joints are watertight before making good the wall around the valve.
10.Fit seal onto concealing plate internal diameter.
11.Apply silicone to the back of the concealing plate [outer diameter] and lubricate the seal using washing
up liquid or similar.
12.Assemble by pushing over the valve body and press up to the wall, remove any surplus silicone.
SHOWER VALVE OPERATION:
The handle adjusts temperature only. However first turning the handle anti-clockwise will switch on the
water to the maximum flow. Further rotation will progressively increase the temperature to the maximum
factory set temperature of 44°C (temperature measured with an open outlet.) Please note 44°C with an
open outlet is described as water flowing straight from the valve. No hose or fixed pipe is involved. Once
fitted with hose or concealed pipe work the outlet temperature will be less due to heat lost in its travel.
A fully open valve will allow 247° of rotary movement for full operation. The temperature if required to be
different from the factory set 44°C can be done so and set to your individual requirements. See MAX
TEMPERATURE SETTING.
This valve performs satisfactorily without flow limiters although it is recommended that they be fitted for the
purpose of economical water usage. The valve can be used in conjunction with most makes of pump on the
market. If you are in doubt or require further information contact us on 0870 1200285.
*With certain permutations of combi-boiler hot supply and mains supply it may be necessary to fit the gray
6-litre limiter.
**IMPORTANT. It is a requirement of instantaneous electric water heaters that a stable flow of water passes
through the heater. Using a flow stabiliser in the supply to the heater can satisfy this requirement. It should
be adjusted to give a flow temperature if 45-50°C from the heater.
SHOWER VALVE INSTALLATION :
Exposed Shower :
Before mounting the exposed valve to the wall, the positioning for pipe work should be decided. Three inlet
positions - top, bottom and rear are available simply by rotating the elbows in the valve body. With the elbow
screwed fully against the valve body it can be unscrewed to suit existing pipe work with centres between
143mm and 151mm, any adjustments should be made to both elbows. Both hot and cold supplies must be
connected to the correct inlet ports identified. The Pegler valve is manufacture against a standard type of
installation, which is for water supplies to be hot on the left and cold on the right when viewing the valve from
the front. If your existing pipe work is "hot on the right, cold on the left," the valve can be rotated through
180°. The outlet adapter & blanking plug can be reversed to give top or bottom outlet as required.
Concealed Shower :
Before mounting the concealed valve to the wall, the positioning for pipe work should be decided. Three
Inlet positions - top, bottom and rear are available simply by rotating the elbows before tightening the elbow
nut. The valve body requires a hole depth of between 65mm to 95mm measured to the finished wall and a
90mm min-160mm max diameter, plus the depth of the retaining screws need to be taken into account
when deciding the valve positioning. It is essential that when installing a concealed mixing valve full access to
the valve can be achieved for servicing purposes. For this reason the elbows provided are fitted with isolat-
ing valves which are essential to the installation. The inlet centres on all concealed models are fixed at
172mm. Rear access to the valve is always preferred wherever possible (e.g. an airing cupboard or panelled
wall), as this would negate the need to disturb any tiling or decorative features at the front of the valve.
Please note - If you find that your installation will mean hot is on the right, cold is on the left, the valve will
need to be rotated through 180° before assembling to the wall. Remove the blanking plug and outlet adapter
using a flat screwdriver and 12mm A/F Allen key respectively.
Please note - Failure to attach the correct feed to the correct inlet will cause valve malfunction.
