Important information Introduction The Quartz Thermo is designed for both built-in and concealed panel mount installation and is supplied complete with adjustable height head. Quartz Thermo provides close temperature stability and fail safe protection when installed on approved gravity or pumped systems and balanced high pressure systems. A cold inlet flow regulator is provided for use with instantaneous (multipoint) gas water heater and combination boiler applications.
Important information Pump installation UNDER NO CIRCUMSTANCES MUST A PUMP BE FITTED DIRECTLY TO THE WATER MAIN. A pump must only be used to boost the pressure from tank-fed supplies. A typical layout is shown on the reverse of this guide. Stored water capacities The minimum capacity of the cold storage cistern should not be less than 225 litres (50 gallons). The capacity of the hot cylinder must be capable of meeting the anticipated demand.
Step-by-step instructions ! In addition to the guide below it is essential that the written instructions overleaf are read and understood and that you have all the necessary components (shown overleaf) before commencing installation. Failure to install the product in accordance with these instructions may adversely affect the warranty terms and conditions. Do not undertake any part of this installation unless you are competent to do so.
5 Set the temperature control lever to full cold (9 o’clock) prior to removing the four screws securing the lever to the valve. Carefully remove the temperature lever to reveal the lilac temperature preset override ring and the white temperature preset location ring. Neither of these parts need to be removed for installation. However if they are removed please take a note of their orientation on the valve prior to removal (as illustrated).
11 Using a silicone based lubricant, lubricate the supply pipe ends and whilst supporting the elbows, push home the supply pipes ensuring the correct orientation for the inlet pipes (HOT LEFT AND COLD RIGHT AS SHOWN ON THE VALVE BODY). Push the valve fully home until a definite stop is reached (tube insertion depth is 25mm). Secure the valve assembly to the fixing surface using the screws provided. 12 Construct a suitable 15mm outlet supply to a suitable point for the wall outlet.
17 Refit the lilac temperature preset override Shroud support ring ring and the white temperature preset location ring if removed prior to installation, taking care to fit the override ring in the correct orientation as outlined in step 5. Prior to replacing the shroud, ensure the shroud seal is in position as indicated. 18 Shroud seal Replace the shroud ensuring that it is fully fitted against the shroud support ring as shown.
23 Ensuring the fixing lugs and locating pins are correctly aligned, carefully place the valve end cap onto the on/off lever and click into position. Adjustable height head installation 1 Prepare pipe work from the shower valve to the required position for the hose outlet using a ø15mm copper pipe. Slide the 15mm gripper ring down the projecting pipe up to the wall face. 2 Trim the projecting pipe to a length of 15-22mm using a rotary type cutter.
7 Drill and plug two holes 642mm-655mm vertically apart using a spirit level if necessary. Fit the rail end clip into position and loosely fit the lower bracket into position. 8 Pass the rail through the handset holder whilst keeping the slider levers depressed with the handset holder pointing in a downward direction. 9 10 Carefully slide the gel hook onto the rail under the handset holder.
14 Connect the hose to the wall outlet assembly after passing it through the gel hook/hose restraint (if required) and run the shower for 15 seconds without the handset attached to clear any internal debris, which may be present.
After installation... Commissioning The Quartz Thermo valve is pre-set to a safe maximum shower temperature. During use, the action of the stop button may be overridden by depressing it as the temperature control is rotated. Should it be necessary to reset the maximum temperature position please observe the following procedures. 1. Ensure that the hot water system is at normal maximum temperature. 2. Turn the temperature control lever to the full cold position (9 o’clock). 3.
User guide Shower operation Turn the on/off control fully anti-clockwise into the open position to turn the shower on. N.B. The on/off knob MUST NOT be used as a method of flow control. Rotate the temperature control lever, depressing the grey temperature limit button if required, to select a comfortable showering temperature using the temperature markings as a guide. Turn the on/off knob fully clockwise into the closed position after use.
Troubleshooting guide Symptom Possible cause Action Water output is either all hot or all cold, or cold only Reversed inlet supplies Check that the supplies correspond with the inlet markings Water output is not hot enough The temperature of the hot water cylinder is too low The cylinder temperature should be at least 15˚c hotter than the blend Water flow through the appliance is too fast Check the flow rate recommendations with the heater manufacturer Flow rate is poor and water temperature is l
