Flow rate chart

Safety shut-off feature

The TM200VP will automatically close off the mixed water flow in the event of either hot or cold water supply failure when installed in accordance with these
installation instructions.

After safety, shut-off shutdown has occurred, and the mixing valve has cooled down, the very low flow may occur. This is normal and is no cause for alarm

Installation

6.1 Safety guidelines for installation

Jointing the compound will cause damage to the internals of the mixing valve and prevent the check valves from functioning correctly.

Therefore, the jointing compound must not be used on the connections and could invalidate the warranty if used.

The use of jointing compounds in other parts of the installation should be avoided or flushed out before fitting the TM200VP.

It is preferable for the TM200VP to be installed with balanced dynamic pressure. However, control will also remain within the specified limits when supply pressures are different, provided that underflow conditions the pressure differential between the supplies remain within the stated specification. The installer must take precautions to ensure this.

Failure to observe these instructions may lead to a potential failure or incorrect operation of the valve.

It is strongly recommended that the pipework be flushed before installing the mixing valve.

• Grit, flux, and other debris will adversely affect the performance of TM200VP.
• No claim for malfunction will be considered if adequate protection against dirt ingress is not provided.

If there is any doubt then a strainer (e.g. Resideo FY32) should be fitted upstream of the TM200VP and on both hot and cold supplies.

6.2 Installation Guidelines

These instructions Plaid be followed to ensure a trouble-free instigation. The installation should make sure that the installation complies with the requirements of the Water Regulations and any other relevant regula­tan.

• Before installing a Tti1200VP, check water flow supply temperatures and dynamic pressures at all hot and ccid taps. A calibrated jug or vessel of known volume and a watch with a second hand can be used for water flow measurements. Alternatively, a water flow gauge can be used.
• Due account should be taken of multiple demands. for example, the simultaneous use of Moor more taps to ensure adequate hot and coil flow rates to the nixing valve is maintained even when the outlets are turned on.
• When installing a wall unit with plastic an appro­priate ‘risen should be used according to the pipe manufacturer’s recommendation.
• Sufficient consideration should be given to the supped of the wit particularly if instilling with plastic pipe. Where necessary, it is recommended to use a copper pipe on at least one leg (the valve outlet to the tap may be the most suitable).
• The Th1200VP has been designed to slow down the but-up of calcium within the valve body. However. in known hard water areas, the use of a water treat­ment device should be corny: laced to promote the trouble-free operation of the controls and fittings.
• h is; minds for the TM200VP to be installed with balanced dynamic pressure. However. control will also remain within the specified knits when supply pressures are different provided that under Row conditions the pressure differential between supp­lies is within the stated specification.
• The TM200VP can be installed in any orientation including vertical or horizontal pipework.
• II is recommended that isolation/service wakes are installed in the supply pipework adjacent to the 11N200VP to fabricate servicing of the valve.
• The TtA200VP is provided with 15mm cc 22nrn compression fitting and flanged CalreCtaS to all three ports. This enables the valve to be fitted loan existing system without straining the lipstick and also assists with the servicing of the mixing valve.

6.3 Installation

1. The TM200VP should be connected in the hot water supply pipe with the flow in the direction of the arrows stamped on the body, ‘+’ = HOT, ‘—’ = COLD, and MIX to hot tap(s).
2. The integral check valves supplied within the tail­pieces of the theTM200VP must be fitted to the hot and cold inlet ports, as shown in diagram 2. This is to prevent loss circulation between hot and cold pipes and they should not be removed under any

Setting the TM200VP

The valve is set by turning the green control knobclockwise to reduce the mixed water temperature and anticlockwise to increase the mixed temperature. The valve has a single turn through approximately 360°, with a central control band from 35°C to 46°C. The hot tap should be left to stabilize before the final set to ensure correct adjustment. For convenience typical settings are marked on the green control knob. These settings will be accurate when dynamic hot and cold supply pressures are equal. They will vary slightly from the indicated figure when hot and cold supply pressures are different and should be used as a guide
only. The mixed water temperature should be set at the temperature required for a particular application (See Table 2).

Locking the setting

Once the correct setting has been achieved it can be locked in position by placing the clear cap over the control knob ensuring the notch in the clear cap and lug on the valve are engaged (see diagram 3). The cap is then secured in place with the screw provided. The actual setpoint temperature can be viewed through the clear window as shown on the locking cap in diagram 3.

The TM200VP is now ready for use.

A typical example

The example shown in diagram 4 below shows a typical system with mains pressure cold feed and low-pressure tank fed hot water installation. Under these conditions, the hot and cold water is separate, and therefore differences in fluctuations in hot and cold flow rates and pressures whilst being a nuisance are not that important. Once mixing valve(s) are fitted as shown in diagram 5 to give a blended hot water temperature, the hot and cold systems are connected and steps
must be taken to ensure that the supply pressures are kept within the specified differential. In diagram 5 this has been achieved by fitting a pressure reducing
valve (for example, a Resideo D05 pressure reducing valve) on the common cold inlet. This not only gives improved performance from the mixing valves but
also the system in general. In a ddition, pressure-reducing valves help reduce the overall water consumption.

1. If new water main is fitted, or work is carried out to the old water main then a strainer should be fitted immediately after the stop tap to prevent debris from entering the mixing valves. If work is carried out to an existing system please refer to the section on installation. If there is any doubt, then a strainer should be fitted.

2. Because pressures vary due to head loss between upper and lower floors as well as pipework layout and sizing, fitting pressure-reducing valves in higher pressure zones will reduce the flow from outlets in those areas minimizing the risk of starving flow in other lower pressure zones.

3. The mixing valves are normally fitted one per hot outlet. The TM200VP can be fitted to serve several outlets provided that both the water supply pressures and mixed flow rates are adequate. To comply with health regulations, no tap should be more than two meters away from the mixing valve.

Commissioning the TM200VP

1. Check that the designation of the TM200VP matches the intended application (Table 2), that the supply pressures are within the range of operating pressures, and that the supply temperatures are within the range permitted for the valve from guidance information on the prevention of legionella.
2. Adjust the temperature of the mixed water following the instructions given in ‘Setting the TM200VP’, and the requirements of the application o record the temperature of the hot and cold supplies o record the temperature of the mixed water at the smallest and largest draw-off flow rates o turn off the cold water supply to TM200VP and record the mixed water temperature and the maximum temperature achieved

The values should not be greater than 2°C of the nominal setpoint shown in Table 2.

Servicing

11.1General information
Most domestic water supplies contain calcium which will separate out when the water is heated in a system.

The degree and speed of scaling depend, amongst other factors, on water flow rates, system design, the degree of hardness of the water, and the temperature to which it is heated.

Over a period, the scale may form within the valve, particularly at the hot inlet where the water is hottest and this may eventually prevent one or more ports from closing fully and thereby impair the temperature control.

Descaling of the mixing valve then becomes necessary.

Because circumstances differ between installations, it is not possible to give a definitive water hardness level that will affect the mixing valve within a certain time period.

Simple scale protection of the incoming water supply on any system will always provide benefits in extending the efficient operating life of thermostatic mixing valves and other fittings before service is required.
Scale protection is essential in applications where water is particularly hard.

If purpose-made measuring equipment is not readily available, a good guide to hardness can be established by checking site experience with the speed of scale build-up in kettles or coffee machines.

11.2Servicing

It is recommended that the mixing valves are inspected on a regular basis, at least annually, or more frequently if performance is impaired, to ensure they are working correctly and that dirt ingress into the system does not cause a loss in performance of the mixing valve.

Please note that during servicing the valve piston should be greased with an approved (WRAS) silicon lubricant.

If required, a Resideo service kit is available for cartridge replacement.

2. Prior to servicing the TM200VP, the mixed water temperature must be recorded Should the tempera­ture be 2°C greater than the nominal setting the following should be checked before dismantling the valve o Check strainers are clean o Ensure check valves are in good working order o Check isolating valves are fully open
3. If these checks are satisfactory then the Resideo service kit is available for cartridge replacement (separate instructions in the service kit detail this procedure). After servicing the commissioning procedure detailed in point 10 under Commis­sioning the TM200VP’ should be followed.

12. In-service testing

Following commissioning, in-service tests (as shown in Commissioning the TM200VP’) should be carried out at 6-8 weeks and 12-15 weeks.

1. If no significant changes (i.e. 1K) occur in either test, a further inservice test should be carried out at 24 to 28 weeks after commissioning.
2. If small changes (i.e. 1 to 2K) occur in one test necessitating adjustment, a further in-service test should be carried out at 24 to 28 weeks after
3. If small changes (i.e. 1 to 2K) occur in both tests necessitating adjustment, a further in-service test should be carried out at 18 to 21 weeks after
4. If significant changes (i.e. > 2K) occur in either test necessitating service work, a further in-service test should be carried out at 18 to 21 weeks after

The general principle to be observed after the first 2 or 3 in-service tests is that the intervals of future tests should be set to those which previous tests have shown can be achieved with no more than a small change in mixed water temperature.
