WITH AUTOMATIC DIVERTER VALVE (T605A & variants)
INSTALLATION, OPERATING & MAINTENANCE INSTRUCTIONS
Approvals
The TSV1-3 Thermostatic Shower Valve within the panel has been independently tested by the WRc and
approved to all the requirements of NHS Model Engineering Specifications D08 Thermostatic Mixing Valves
(Healthcare Premises) to the following designations and for the following applications:
HP-S
LP-S
Supply Water Pressure requirements
The minimum water pressure required to achieve a satisfactory spray at each spray-head is a dynamic head of
20m (30 psi, 2 bar) measured from the spray head.
Note that dynamic head is measured with the water running.
The maximum recommended supply pressure is 6 bar (90 psi, 60m head) for hot and 10 bar (150 psi, 100m
head) for the cold.
Supply Water Temperature Requirements
Max. Hot Water Temperature*
Min. Hot Water Temperature#
Max. Cold Water Temperature#
A minimum temperature differential of 5°C should exist between the mixed water temperature and each inlet
temperature.
Note that requirements marked * originate from WRAS approval of non-metallic components, and those marked
# originate from HTM 04:01, Part A, 2007.
Temperature Adjustment Range
The mixed water temperature can be adjusted from cool through to a top limit (which can be preset during
installation – factory set to approx. 41°C - with full anti-scald protection throughout the range).
Water and Energy Conservation
The TSV1 range of shower panels is fitted with a flow regulator at the shower outlet to reduce the flow rate and
conserve water and energy. The drawing at the end of this document provides information for accessing the
flow regulator for removal or replacement.
Every HORNE TSV1-3 is supplied with an integral WRAS approved single check valve and integral large
surface area strainer. The Shower Panel terminates in 15mm copper pipes for hot and cold supplies. The hot
pipe is on the left, cold on the right, when viewed from the user's perspective.

- Page 3 Horne Engineering Ltd Fig 3 5) Drill Support Holes Carefully remove the panel from the temporary support screw and, being careful not to scratch the panel or its covers, lay it down where it will not be damaged. Drill 4 x 7.0mm holes and install the wall plugs.
- Page 4 Connect the hot water supply to the left hand inlet, and cold water to the right-hand inlet (see Fig 5). DO NOT OPEN THE WATER SUPPLIES AT THIS STAGE AS THEY HAVE NOT BEEN FLUSHED OUT TO REMOVE THE DEBRIS IN THE PIPEWORK. SUCH DEBRIS CAN DAMAGE THE TSV1-3 VALVE.
- Page 5 Flush out the pipework in accordance with Water Bylaws 2000 (Scotland) and BS 6700:1997 (England & Wales). The use of a Horne flushing kit is strongly recommended, because this connects directly to the water inlets on the mixing valve. Access to the flushing points is gained from underneath the casing through the lower end cap.
- Page 6 Ensure that the TSV1-3 on/off control is closed (i.e. turned fully clockwise) and open the supplies. Open the low level servicing valves on the TSV1 casing (Fig. 6). Adjust the temperature control and check for any water leaks upstream of the TSV1-3 valve. Make good any leaks found. The valve is now ready for commissioning.

TSV1 Panel Mounted Shower Valves are available in versions with flexible braided stainless steel inlet hoses rather than top entry isolating valves. These versions have Product Reference codes with the suffix B, e.g.

Page 9: Maintenance
“O” rings prior to installation. Lightly smear the outside diameter of the slide valve with silicon oil prior to installation. Replace the thermostatic element and slide valve assembly at least once every 6 years in all TSV1-3 valves, or more often if problems are experienced or in installations where the water is aggressive. - Page 10 Horne Engineering Ltd If either check valves is leaking then the inlet elbow (complete with check valves and strainer basket) should be replaced. It is not possible to satisfactorily remove the check valves itself from the inlet elbow and should not be attempted.

Page 11: In-Service Testing
The frequency of in-service testing depends upon the condition of the water passing through the TSV1-3. In- service testing must be carried out more frequently in hard water areas than in soft water areas. As a general guide, in-service testing should be carried out at intervals somewhere between six months and 12 months. - Page 12 Horne Engineering Ltd Insert DRAWING 10393 showing position of Flow Reg.
