Installation Instructions

FELTONMIX^® Shower Valves Types U, E and H

1. Provide a stud or other suitable fixing in the shower wall on which to mount the shower valve Shower head at about eye level (between 1.5 and 1.8 metres) is a good guide. Ensure distance from mounting face to front of wall lining is 45mm.
   
2. Flush out pipework. Mount shower valve assembly and secure with two wood screws provided. It is important that the pipes which are now connected directly to the isolator valves on each side of the shower valve assembly line up correctly with the isolators and do not place any unnecessary strain on the valve assembly. Ensure isolators are open, (turn anticlockwise). Do not apply heat to pipes connected to the mixer as internal damage may occur.
   Note: When tightening crox nuts it is important to hold the hexagon face to prevent any strain on the isolator. Do not attempt to tighten or remove the brass nipple from the isolator. This has been installed with correct pre-loading at the factory and any alteration may cause damage to the isolator.
   
3. Cut an access hole in the wallboard to suit the shape of the wallplate using the template provided.
4. Position the wallplate over the valve outlet and fit the two 1¹/8 x 7 screws provided through each wallplate slot and into the valve body lugs. Tighten screws alternately until wallplate is firmly clamped to the wall.
   
   Do not overtighten. Light pressure is sufficient to clamp the wallplate firmly.
5. Rotate slotted sleeve on valve body (projecting from central hole of wallplate anticlockwise and fit handle to sleeve, locating at the 4 o'clock position. Handle should recess into the wallplate and match its contours. Ensure that handle has about 10 mm of engagement.
6. Screw showerhead into valve assembly until full home. If necessary unscrew the showerhead part of a turn to bring it to the correct position. The O-ring seal fitted to the showerhead stem will ensure a watertight seal. Tape or hemp on the thread is not necessary or desirable.
7. CHECK OPERATION. When installed check that the handle swins from right to left from OFF to HOT. Total movement is about 130°.

TROUBLE SHOOTING

Insufficient Water Flow

Check that the correct model (Type U, Type E or Type H) has been installed for the supply conditions. Check fi lters for foreign matter.

SHOWER HEAD

Your Feltonmix shower head is manufactured from self-cleaning plastic materials and cleaning with a soft nylon brush and bathroom cleaners is usually sufficient.
If dismantling is required, insert the two leg's of the Feltonmix spanner into the face of the rose. Turn the rose approximately thirty degrees and withdraw it from the shower head body.
When assembling ensure that the sharp outer edge of the soft spray ring is located at the front edge of its support ring. Align the assembly pips on the front face of the rose and lip of the body. Push them together until they click twice.
