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 reduce 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 Customer Promise.

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.
The mixing valve should be installed in accordance with the water bye laws. For further
details refer to the latest copy of Water Bye Laws guide or your local water authority.
It is Pegler’s recommendation and good plumbing 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
supplies are not equal pressures then a Non Return Valve (Pegler 801 Non Return Valve)
should be fitted.
The shower head of any shower hose pipe should be fitted by 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.

Water Supply Operating Pressures.
Pegler thermostatic shower fittings have been designed to function under the following
Maximum static water 5.0 bar
Minimum flowing water pressure 0.1 bar
Optimum operation pressures 0.1 to 5 bar
Maximum hot supply temperature 85°C – Recommended maximum hot supply 65°C
Minimum supply temperature 5°C – Higher than maximum required mixer temperature.
Minimum difference between hot and cold mixed temperatures 10°C
Please 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)
Pre-Installation Checks.
Fixing Wall Outlet Elbow for Concealed Showers Only
Ensure all supply pipes are flushed 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
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
performance. Therefore we recommend the fitting in-line of service valves upstream
of the shower valve to allow for servicing of the shower.
Ensure that there is sufficient space to install the product without hampering its
Care must be taken during installation to prevent any risk of damage to the product or
injury to installer.
Installation must be carried out by a qualified and competent person and in
accordance with the instructions supplied.
Installations must comply with all Local and National Water Authority Regulations, and
Building/Plumbing Regulations.
Please ensure that you have read and understood all sections of this manual before
Dynamic Head
Flow Rate
Maximum Temperature Setting
Please note flow rates in litre/min on equal pressure drops and open valve outlet.
Recommended Minimum Dynamic Supply Pressure 0.1 bar
For valves have a factory preset temperature of 43°C
The temperature differential required between hot supply and outlet temperature is a
minimum of 10°C (for example if the required outlet temperature is 43°C then the incoming
hot temperature has to be minimum 53°C)
Please Note
The 43°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.
The temperature if required to be different from the factory set 43°C can be done so and
set to your individual requirements. See Maximum Temperature Setting.
Decide on location of your elbow and plumb accordingly. Make good the wall with
tiles etc.
Remove chrome cover and pull out brass insert, be careful not to loose the
screws or the horseshoe shaped retaining clip.
Screw brass insert into wall fixing using the two flats provided.
Push plastic sleeve into position and mark for screws.
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
Once screwed to the wall push on the plastic sleeve and fasten.
Slide the retaining clip into the two slots to clamp in position.
Slide chrome cover on to finish. At this point silicone can also be used to seal
around the face of the cover and wall.
The mixer is factory preset at 2.5-3 bar and at a temperature of 60-65°C for hot
water and 10-15°C for the cold one corresponding to a mixing temperature of
38°C. In every domestic installation temperatures a nd inlets pressures can differ
from those of production.
Pegler do not recommend changing the temperature any higher from the
preset temperature of 43°C
To change the water temperature first using a common thermometer for domestic
use – check the current temperature level.
Remove the temperature control handle
Turn the broached ring of the cartridge until the blended water reaches the
desired temperature.
Re-assemble the temperature control handle.
Shower Valve Service and 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.
Check that the valve has been installed correctly
That the hot water temperature is adequate; the recommended minimum supply
temperature is 10°C higher than required mixer temperature.
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)
Filter Cleaning
Concealed Shower - Introduction
Through years of use impurities and limescale could restrict flow of water through the
To clean it follow the instructions hereunder:
1. Shut off water supply to both inlets.
2. Unscrew the levers (1) and the grub screws (2) with an allen key 2.5 mm
3. Remove the cover plate (3)
4. Unscrew the four fixing screws (4) from the wall
5. Unscrew the nuts (5) of the two inlets and the outlet and remove the valve body
6. Remove the two filters (7) from elbows (8)
Please note: Soak all metal parts in descalent, wash off in clean water.
Examine all seals and replace if necessary; maintenance kits are available from
Pegler technical.
Use silicone based grease on all seal (use a light smear only) and the thread of
the spindle and spindle housing.
Re-assemble the filters (7) to the elbows (8)
Re-assemble the valve body (6) and screw the three nuts (5)
Screw the four fixing screws to the wall
Re-assemble the cover plate (3)
Screw the grub screws (2) and the levers (1)
Decide on location of pipe installation.
Three inlet positions are available for connections of the exposed valve. Top, rear and
bottom are available and can be changed by simply rotating the inlet elbow.
The valve body requires a hole depth of between 52.5mm to 77.5mm measured to the
finished wall and 150mm max diameter hole, plus the depth of the retaining screws
need to be taken into account when deciding the valve positioning.
Rotate the elbows to the desired position and check inlet centre distance.
It is essential that when fitting a concealed shower (of any kind) that access to the
shower valve can be made for service and maintenance purposes. The inlet centres
on all concealed models are fixed at 145mm. Rear access to the valve is always
preferred wherever possible location nearing an airing cupboard / panel wall or similar
are advised as this ensures no disturbance to tiles etc.
If location like the above is not possible then a removable access panel of 300mm
square minimum fitted to a simple wooden framework could be installed to allow full
access and removal of the valve if necessary. A panel of this nature could at least be
tiled and held in place with mirror screws.
Closely fitted isolating valves (not supplied) are advised when fitting any type of
concealed unit. For maintenance and servicing measures required on the valve and
the restrictive area they are likely to be mounted in.
Once the valve has been installed and tiling around the shower valve complete, all
seals can be fitted to the cover plate.
Locate cover plate over handles and around the shower valve body and push towards
the tiled wall. A bead of clear silicon around the outside of the plate is not required
however may be applied if felt necessary to do so.
It’s also imperative that the filters provided are used.
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

On this type of installation you may also need to remove the temperature control
handle, the temperature stop ring and the flow control and relocate. This can be done
at your discretion!
Shower Valve Operation
The front handle adjusts temperature only by progressively increasing the temperature to
the maximum factory set temperature of 43°C (temperature measured with an open
outlet.) The lever handle behind operates flow on and off as well as adjusting the flow rate.
