1.3 SYSTEM DETAILS
Taps and Shower fittings
a. Ensure that all terminal fittings are suitable
for mains pressure. Use aerated taps
whenever possible to prevent splashing.
b. Aerated taps are recommended to prevent
splashing. Any type of shower mixing valve
can be used as long as both the hot and cold
supplies are mains fed. However, all mains
pressure systems are subject to dynamic
changes particularly when other hot and
cold taps/showers are opened and closed.
To minimise the impact of this we would
always recommend the use of thermostatic
showers with this appliance.
The shower head provided must also be
suitable for mains pressure supplies.
However, if it is proposed to use a ‘whole
body’ or similar shower with a number of
high flow/pressure outlets please discuss
with the Gledhill technical department.
c. Note that the shower fittings must comply
with the backflow prevention requirements
(Para 15, Schedule 2) of the Water Supply
Regulations 1999.
d. A bidet can be supplied from the Accolade
2000 appliance as long as it is of the over rim
flushing type and incorporates a suitable air
gap.
Dead leg volumes and secondary hot water
circulation
If the dead leg volume of the hot water draw-off
pipework is excessive and the delivery time for
hot water to be available at the tap is more than
60 seconds you may consider using:-
a. Trace heating such as the ‘Raychem HWAT’
system. Please call Gledhill technical
department for further details.
OR
b. A secondary hot water circulation system
as shown schematically in figure 2.2.
Note:
It is not recommended that direct models
utilizing an E7 tariff are provided with a
secondary hot water circulation system.
