SAFETY : WARNINGS

WARNING - This product can deliver scalding temperatures if not operated, installed or maintained in accordance with the instructions, warnings and cautions contained in this guide.

The function of a thermostatic mixing valve is to deliver water consistently at a safe temperature. In keeping with every other mechanism, it cannot be considered as functionally infallible and as such, cannot totally replace a supervisor’s vigilance where that is necessary. Provided it is installed, commissioned, operated and maintained within manufacturers recommendations, the risk of failure, if not eliminated, is reduced to the minimum achievable.

Installation of the Bar Valve

Important! Before installing the pipework, please ensure that there is a minimum of 1065mm height clearance to allow for the rigid riser and overhead to be installed above. If installing in a restricted height area, a shorter riser rail can be ordered as a spare part.

The thermostatic bar valve should be installed where it will be supported by xed pipework.

1. Install the pipework, making sure that it is set at the correct distance apart (150 ± 24 mm)

and solidly xed.

2. Apply suitable thread sealant (not supplied) and attach the offset connectors to the pipework in the wall. The offset connectors must protrude between 40 and 43 mm from

the nished wall.

Note! Connections are: Hot-Left, Cold-Right. This is very important as this product

does not allow for reversed inlets.

Screw the concealing plates onto the offset connectors until they come into contact with the wall.

Caution! Make sure that the supply pipework

is ushed before installing the Bar Valve.

Assemble the bar valve with a sealing

washer/lter in each inlet and attach to the

offset connectors. Note! Connections are: Hot-Left,Cold-Right.

Installation of the Shower Fittings

1. Slide the hose retaining ring and the clamp bracket onto the middle bar, and then screw

the middle and lower bar sections together.

2. Screw the riser arm to the middle and lower bar section.

3. Push the riser bar into the top of the bar valve.

Note! The riser bar must be located correctly, push down rmly to seat it.

4. Insert the wall xing bracket into the riser arm mounting boss, then swivel the bar if

necessary to reposition the wall xing bracket against the wall.

Note! The grubscrew mounting hole must be positioned at the top.

5. Mark the holes for the wall xing bracket.

Note! Use a spirit level to ensure the bar is vertical.

6. Remove the wall xing bracket from the mounting boss then remove the riser bar from

the bar valve.

7. Drill two holes to suit the wall xings, ensuring that the bar valve is protected from debris.

Fix the bracket to the wall.

8. Ret the riser bar into the bar valve and then put the concealing cover onto the riser arm

mounting boss.

9. Push the riser arm mounting boss onto the wall xing bracket.

10. Fit and tighten the grubscrew (2.5 mm hexagonal key) into the hole on top of the mounting

boss then push the concealing cover over the wall xing bracket.

11. Tighten the grubscrew at the valve end and t the grubscrew cover.

12. Screw the xed shower head onto the riser arm. Make sure that the washer is tted.

Note! The Moxie wireless speaker does not have to be tted at this stage.

13. Fit the shower hose onto the bottom outlet of the bar valve.

Note! The shower hose has slightly different sized conical connections at each end (the

smaller diameter / longer length conical is identied with a Red protective cover or a White label). The end with the red cover or white label connects to the showerhead, the

clear end connects to the valve.

14. Push the shower hose through the retaining ring and screw it to the showerhead.

15. Place the showerhead into the clamp bracket, adjusting the angle and height to the users

preference.

COMMISSIONING

Bar Valve Commissioning

Maximum Temperature Setting

Before using the shower, the maximum temperature must be checked to make sure that it is at a safe level. It has been preset to a safe showering temperature under ideal conditions at the factory, appropriate for most systems. However, site conditions and personal preference may make it necessary to reset this temperature.

Note! Make sure that the hot water temperature is at least 55°C and that there is sufcient

supply.

Caution! Before testing the mixer, make sure that the hot and cold water is owing correctly

by exercising the temperature selector knob between the cold and hot stops.

1. Turn the temperature selector knob anticlockwise until it stops and test that the temperature of the water from the shower outlet is hot enough.

2. If not, depress the override button and carefully rotate the knob further. If the water temperature is still not hot enough complete the following procedure.

3. Rotate the temperature selector knob back to the override position.

4. Push in and rotate the concealing cap clockwise to remove. Remove the xing screw.

5. Pull off the temperature selector knob without disturbing the stop assembly.

6. Replace the temperature selector knob so that the lever is the 1 O'clock position.

7. Rotate the temperature selector knob against the stop, wait for the water to stabilise

and test that the temperature of the water from the shower outlet is hot enough.

If the water temperature is still not hot enough repeat the procedure until a maximum

safe temperature is achieved at the override position.

8. Ret and tighten the xing screw, ret the concealing cap.

Cleaning

Many household cleaners contain abrasives and chemical substances, and should not be used

for cleaning plated or plastic ttings. These nishes should be cleaned with a mild washing

up detergent or soap solution, and then wiped dry using a soft cloth.

Important! The showerhead must be descaled regularly, keeping the showerhead clean and free from limescale will ensure that your shower and showerhead continue to perform

to their maximum. A blocked showerhead can restrict the ow rate and may cause damage

to your shower.

The Moxie speaker must only be cleaned with a damp cloth and then wiped dry. Do not spray, submerge or pour water into the speaker as product damage will occur.
