INTRODUCTION The fittings covered by these instructions should be installed in accord- ance with the Water Regulations published in 1999*. Ideal Standard strongly recommends that these fittings are installed by a professional fitter. *A guide to the Water Supply (Water Fittings) Regulations 1999 and the Water Byelaws 2000, Scotland is published by WRAS (Water Regulations Advisory Scheme) Unit 13, Willow Road, Pen-y-Fan Industrial Estate, Crumlin, Gwent, NP11 4EG.
WATER SUPPLY CONDITIONS Introduction These thermostatic shower mixers are manufactured to the highest standards The mixer is intended to be installed on high pressure systems (1.0 bar or greater). The mixer has safety features such as cool body technolgy and temperature limit stop. To make installation easier, fast fix wall mounts are supplied. Ø15mm water supply pipes should be installed at 150mm horizontal centres in the wall, behind a shower panel or tiled duct wall.
WATER REGULATIONS CATEGORIES OF RISK The water regulations published in 1999* take a new approach to backflow in that they look at different categories of risk. The installer must assess the risk from the various categories of fluid in adjacent appliances before determining the level of backflow protection required for a particular installation.
PRE-INSTALLATION NOTES The thermostatic mixing valve must be installed in such a position that maintenance of the TMV, its valves and the commissioning and testing of the TMV can be undertaken. Ceratherm T50 is an exposed two hole thermostatically controlled shower mixer. This product is designed to provide water from ambient cold up to a safe maximum temperature for bathing.
INSTALLATION IMPORTANT BEFORE CONNECTION, FLUSH WATER THROUGH PIPEWORK TO REMOVE ALL DEBRIS ETC. WHICH COULD DAM- AGE THE VALVE MECHANISM Wall mount mixers Pair of wall brackets A7216AA A7221AA A7227AA with connectors & A7697AA escutcheons Template x1 Ø15mm copper supply pipes should be run within the wall cavity. Hot supply pipe should be on the left hand side and the cold on the right.

Place the brackets over the exposed pipes and use the template provided to position them 150mm apart. Mark the hole positions for the fixings onto the mounting surface. Ensure that the positions of the holes will not result in damage to the pipework inside the wall cavity during drilling.

Screw the brass adaptors over the pipes into the plastic brackets. 36mm A/F Spanner flats are provided, hand tightness is adequate. Fit the olives to the pipes prior to screwing the two 3/4“ connectors into the wall mount plate using a 1/2“ allen key. The connectors will have to be secu- rely screwed in to form the necessary compression joint between the olive, wall...
A7697AA As with the bar shower mi- xer, the wall mounted bath/ shower mixer is assembled to the wall brackets in the same way to complete the installation.

The functionality of the flow control handle is the same for all products except A7225AA &...
A7225AA & A7227AA Q=0% Q=50% Q=100% Right handle controls the 3 function diverter • This handle is shown above parked in the off position (giving no flow at this position). • Rotating this handle downwards from the parked position, commences water flow & will direct water to the bottom outlet of the mixer.
TEMPERATURE ADJUSTMENT If the mixer is not discharching 40°C water when the temperature handle is parked & aligned with the body, then (if desired) this can be adjusted as follows: 40°C 40°C 1-2. First remove the temperature control handle (left side) as detailed in section 16, steps 1 to 3. Before sliding the handle off, ensure the dot on the handle is inline with the 40 marker on the mixer.
COMMISSIONING & PERIODIC CHECKS •A7216AA •A7221AA •A7227AA •A7697AA. The following procedures should be carried out after installation and every 12 months after to ensure that the valve is functioning correctly. Check that: 1. The application of the thermostatic valve matches the approved designation. 2.
COLD WATER ISOLATION (CWI) TEST CWI test is a guide to showing the performance of the thermostat. Prior to CWI test: • Make sure that the temperature handle is aligned in the 40°C position. • Make sure the supply temperatures are within the ranges 55 to 65°C for hot, & 5 to 20°C for cold. •...
THERMOSTATIC CARTRIDGE AGEING Following many years of normal service you may notice the following: 1. The need to carry out more frequent adjustment of mixed temperature. 2. The thermostatic element may not pass the CWI test. These issues could be due to the ageing of the thermostat which loses some expansion capability over time.
