IMPORTANT. Before commencing maintenance on the shower isolate the hot and cold supplies.
When maintenance is complete ensure the shower valve is checked and fully commissioned before use.
PARTS LIST
1. Fault, After installation shower only runs Hot or Cold and will not mix.
Hot & Cold supplies are plumbed the wrong way around. Remove the thermostatic cartridge, undo the 52mm AF clamp nut
and pull the cartridge out (use the temperature knob to aid removal) reinstall the thermostatic cartridge with the lug pointing
away from the hot and cold inlets.
2. Fault, Shower will not run hot enough when first installed.
Maximum temperature needs adjusting, see SETTING THE TEMPERATURE
3. Fault, Cold water tracking through the valve into the hot water system.
Check and clean the non return valve cartridges
and gauze filters located under the non return valves. (See illustration on Mounting and plumbing stage).
4. Fault, Shower will not run hot when first installed.
See SETTING THE TEMPERATURE. Check hot water supply from
boiler is at specified temperature. See IMPORTANT.
5. Fault, Shower only runs cold or lukewarm when first installed.
Thermostatic cartridge may have debris trapped in the
cold side. Clean thermostatic cartridge.
6. Fault, Very low flow or no flow (gravity)
. Check Hot & Cold feeds (the valve will shut down if either Hot or Cold supply
fails). Ensure the correct operation of any flow switches (in pumped applications).
7. Fault, No flow or very low flow (gravity fed installations)
. Very low pressure or blocked filters or pipe work.
8. Fault, No flow or very low flow (pump fed installations).
Flow rate may be insufficient to activate booster pump flow
switches, check pump requirements.
9. Fault, Vibration or hammering.
Dynamic water pressure ratio between hot and cold inlets greater than 5:1 maximum. For
optimum performance the inlet pressures should be balanced to within 10% of each other. Check for loose pipe work.
10. Fault, Shower will not turn off, turning flow control has no effect.
Shower may be plumbed to wrong outlet.
