20 Minute Rating
Your shower is fitted with an auto resetting safety thermal cut-out. If it is left running
for over 20 minutes, the thermal cut-out may switch off. The thermal cut-out will
automatically turn on again when the motor has cooled down.
2. IMPORTANT INSTRUCTIONS
1.WARNING – The cold water must be connected to the top inlet valve. The hot
water must be connected to the bottom inlet. Incorrect connection will prevent
correct operation of the system.
2.Do not connect to mains water pressure. The Osprey power shower cannot be
used with combination boilers.
3.A minumum supply head of 1 metre is required. The water level in the cold
water storage tank should be 1 metre above the unit.
4.Do not use any jointing compounds such as Boss White. Abrasive compounds
will block the control valve and also damage the pump seal.
5.Solder Flux must not be allowed to come into contact with any of the plastic
parts. Flux will seriously damage the plastic.

TURN OFF ELECTRICAL SUPPLY BEFORE REMOVING COVER.
8.Setting maximum shower temperature
a After thoroughly testing and running the shower to ensure the hot water supply
is up to maximum temperature, test shower maximum water temperature to
ensure that it is not too hot. The temperature “limit stop” as fitted is set to
give a maximum shower water temperature of 42°C ±1°C.
b If a hotter shower water temperature is required, the maximum setting can be
re-set as follows:
i)Remove temperature control knob.
ii)Remove “limit stop” with screwdriver as shown
in Fig. 29.
iii)Using a sharp knife, cut off one segment of
the limit stop as shown in Fig. 30.
iv)Replace temperature “limit stop” into control
knob as shown in Fig. 31, making sure
Fig. 29
to locate to the right hand side of the barrier,
with the cutting guides facing upwards, but not
into the knob. The “limit stop” will easily fit
back into place, if not it is the wrong way
round.
c The desired maximum shower water
temperature can be set by altering the “limit
stop” size to suit.
9.Proceed with completion of installation.

Turn on the shower by turning the temperature control knob anti-clockwise.
Adjust temperature as required. Flow rate can be varied by adjusting the flow control
knob.
Turn off the shower by turning the temperature control knob fully clockwise.
There is no need to adjust the flow control when turning of f the shower.
14. OPERATING YOUR NEW OSPREY –
Thermostatic Model
Ensure electricity and both hot and cold water supplies are turned on. Turn on the
shower by pushing on/off flow control knob.
Adjust temperature and flow rate as desired.
To turn off, push on/off flow control knob.
The temperature control is independent of the on/off flow control and can be
left in the selected temperature position until the next time the shower is used.
There is no need to set to cold position.
The first time the shower is used there may be some residual air in the
system. This may cause uneven flow, spitting from the shower handset and unusual
noise from the pump. This should clear quickly and disappear with further use.
Note: If the water flow stops but the pump continues to run, switch off immediately.
Refer to Fault Finding Section 11, paragraph C.
15. SERVICING
The most common cause of poor shower performance is blockage of the handset
spray plate holes. They are usually blocked by dirt or limescale deposits, which is
more common in hardwater areas. Regular cleaning and descaling is recommended.
To maintain a good flow and spray pattern the handset should be cleaned

16. FAULT FINDING
APUMP DOES NOT RUN
1. Check mains wired correctly and switched on – fuse 3 Amps correct and operable.
2. Check electrical connections.
BWATER DOES NOT FLOW
1. Check that all supply valves (including isolating valves) are turned on.
2. Check cold and hot water are connected to the correct inlet control valve.
CPUMP STOPS – water flow reduces
1. An automatic anti-scald system is fitted. If, for any reason, the shower water
temperature starts to exceed the scald temperature, the pump will be switched
off, until the water temperature is corrected.
To correct, adjust temperature control knob clockwise to reduce shower water
temperature.
2. The motor is fitted with a thermal cutout. Should the pump be run for an
excessive period, it will cut out. When the motor cools it will self-reset.
