Before making water supply connections ensure that hot supply is connected to the left hand
tailpipe and the cold supply to the right tailpipe, when viewed from the front. If supplies are the opposite way
round, these will have to be crossed before connecting the mixing valve.

Re-setting maximum temperature.
Re-setting the maximum temperature is not advisable.
Open the water and check the temperature with a medical thermometer
until it reaches 38ºC indication placed on the knob (C) with the slot
on the retainer (D). When the operation is over, tighten the screw (B)
and insert the plate (A).
The BTS is supplied factory set at 46ºC for showering applications we
recommend a temperature no greater than 43ºC.
It is essential that when using the shower function of the BTS the outlet temperature is reduced to prevent
The following temperatures are recommended when using the BTS BATH 46ºC SHOWER 43ºC
Operating the Fully Thermostatic Bath and Shower Mixer.
The purchase of this fully thermostatic Bath and Shower Mixer gives you complete confidence that you can
both bathe and shower in perfect safety.
Operating the central easy grip handle fully controls both the bath and shower water temperature and with an
ambient temperature limit stop at 38 degrees, you know that safety is at heart of this product.
When in operation of either bath or shower both hot and cold handles are to be turned on to operate the
thermostatic control. Failure to not turn on both handles will not allow water to flow correctly as designed,
due to the safety feature designed within.
The default operation is always the bath and then diverter used at the rear of the fitting to change water flow
over to the shower. When either option is in use however, the temperature control is then co-ordinated by
the central handle.
Lower the diverter knob (H) and turn clockwise in order to insert the dowel (I) in the
housing on the auger body (L). Now the water jet shall pass through the flexible shaft (F).
Return the diverter back to its position by following the above instructions backwards.
Please note however upon using the manual override it is always recommended
to divert back to bath after use, so unforeseen discharge from the shower head
upon next time of usage is not hazardous to the potential bather.
Care & 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

It is important to ensure that the water supplies to your taps and mixers are connected in accordance with
the water regulations (WRAS) requirements and good plumbing practice.
It is Pegler’s recommendation and good plumbing practice that the supplies of hot and cold water to the
bath/shower mixer should be at equal (balanced) pressures 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 non
return valves should be fitted (supplied) Pegler supply two non return valves, two filters, two retaining clips
and a flow regulator held with a brass housing.
These products have been designed to function on all types of water systems
Should excessive flow be experienced, then it may be necessary to install a Pressure reducing valve (PRV). It is
also our recommendation and good plumbing practice that full bore servicing valves (PB300) should be
installed upstream in the water supply line.
NOTE – If a pump is to be installed to boost gravity supplies (as fig 1) please refer to the pump manufactures
Pegler fittings have been designed to function under the following conditions:
Minimum bath supply pressure 0.1 bar
Minimum shower diverter operation without manual fixing 0.2 bar
Hot water supply temperature 85ºC Maximum.
Cold water maximum supply temperature 25 ºC.
Valves that operate outside these conditions cannot be guaranteed to work /operate correctly.
The outlet for the shower is 1/2” BSP male thread. This will accept standard shower hoses screwed directly
onto the outlet. Refer to the Francis Pegler luxury showers brochure for a comprehensive choice of ‘Waterfall’
shower kits. All sliding rail kits come with a hose retaining ring ensure that the handset cannot be dropped
into the water creating a possible back syphonage problem.
IMPORTANT. Before making any inlet pipe connections all supplies MUST be thoroughly flushed to remove
any debris. Failure to do so could result in damage or low flow from the mixing valve. It is a requirement of
Byelaw 55 of the Water Fittings Byelaw Scheme that this function is undertaken. Before making any pipe
connections to supplies, flow regulators may be required at this stage if required.

Pre-Installation Checks
When planning the plumbing for your Bath and Shower Mixer installation it is recommended that the hot and
cold supplies are independent for gravity fed and pumped systems, and that no other draw off is on the
same feed. For unvented and gas heater installations it is preferable that both supplies are the first on the circuit.
The hot and cold inlets for your bath and shower mixer are hot on the left and cold on the right when viewed
from the front of the fitting. Connections MUST be made in this way. Failure to do so is dangerous to the user
and could result in irreparable damage to the internal valve mechanism.
It is our recommendation and good plumbing practice that a full bore service valve also (Pegler PB300) should
be installed in the inlet supply lines.
a) Remove bath panel to gain access to securing the plumbing connections.
b) Ensure water is turned off and has been fully drained.
c) Disconnect both supplies.
d) Unscrew backnuts and remove existing fitting or taps.
e) Clean tap platform before installing your new Bath and Shower Mixer.
f) Place sealing gasket on top platform in-line with existing holes.
g) Locate Bath and Shower Mixer through holes and secure to tap platform with brass backnuts provided.
Using the additional sealing washers beneath the ware.

NOTE – When connecting the mixing valve to the mains supply it is recommended that the non return valves
are fitted on both inlets. This is also imperative if the supply of water is unbalanced on the two inlets.
Remove the plate (A) inserting a pin in the hole behind the knobs. Loosen the
screw (B) remove the knob (C) and the temperature retainer (D). Use the special
key to unscrew the thermostatic cartridge (E) and remove it from the body of the
tap. Descale with vinegar and lubricate the gaskets with head-resistant grease.
Re-assemble the whole by following the above-mentioned instructions backwards.
In all installations the minimum fitment must be in order:
Two check valves first-installed with spring loaded central inlet allowing
for the flow of water into the mixer
Next the two flat filters-the installation of these is important to ensure
that any chance of debris
into the thermostatic elements is removed. The lack of installation of
these could cause the unit to
malfunction and make void any warranty on the product.
Finally to hold the above items in position it is equally important that the retaining clips are used.
These are to be located in the groves machined on the inside if the tails by squeezing the clip and locating into
Installations defined where the flow regulator is required, then this should be in place of the check valve.
(The Pegler flow regulator combines a check valve and comes complete in a brass housing) This should be
pushed in place ensuring the spring loaded central inlet allows the flow of water into the mixer. Its location
should always be in the cold side. Push the regulator down the length of the tail and locate securely with the
outside ‘O’ ring.
