Water supplies
The Nova-Flo
®
valves are not hot or cold specific, so hot or cold water
can be run through either side.
1. Bath and Wall Mounted taps: (See Fig. 3)
The water supplies for the hot and cold feeds must pass up through
each side valve (Fig. 1, E) of the Nova-Flo
®
unit respectively with the
upper ¾" BSP connectors (Fig. 1, B) leading to the tap controls or mixer.
2. Bath Filler and Waste Combinations: (See Fig. 4)
The mixed water supply fed from the tap controls is to be split and
directed equally to both side valves. The upper connections are then
to be reconnected and a branch led to the filler and waste head.
Use of a Thermostatic Mixing Valve (TMV)
It is recommended that a TMV be installed prior to the Nova-Flo
®
unit.
e.g. Thermally mixed water should be directed through one side valve
of the Nova-Flo
®
unit. Nova-Flo
®
is rated at a maximum hot water
temperature of 60 degrees Centigrade.
Purging of system
Once fitted, the system will need to be purged to clear any air trapped
inside. This is done by allowing the taps to run at full flow for 1 minute,
then turning them off. Repeat this procedure three times. Should the
valves actuate, simply turn off the taps, wait for five seconds then turn
them on gently. Once the system is purged of air, activation of the valves
such as this will not occur. In some installations with an exceptionally fast
flow rate, unexpected water shut off may occur before the bath is full. In this
occurrence simply restrict the water flow by closing the supply valves slightly.
Testing
Test for leaks before replacing any bath surround or cladding.
To ensure correct operation, you are advised to check its operation
once every six months. To do this, keep the taps on and direct water
from a shower head or pour water from a large jug into the overflow
outlet until activation. Whilst doing this it can be quicker to cup a cloth
with your hand below the overflow outlet to channel more water into it.
Should the overflow system ever become clogged with soap, hair etc.
resulting in a blockage remove the lower barb connector by rotating
it 45 degrees anti-clockwise and clear any debris with a cotton bud or
similar, then refit the barb connector. Care should be taken not to lose
the o-ring. Should more intensive cleaning be required you can find
more maintenance guidance at
www.nova-flo.com
Resetting the water upon activation of the valves
If water pours down the overflow outlet, the taps will be substantially shut
off. There will remain a small trickle of water which is intentional and reminds
the user to turn off the taps (the overflow can easily handle this trickle).
To reset the unit, ensure there is no more water going through the
overflow then simply turn off the taps and wait for five seconds. Upon
opening the taps full flow is resumed. Your taps and water supply will be
unaffected in normal use.
Recommended fittings
To ensure compatibility we recommend installers use the Nova-Flo
®
push-fit or compression fixing packs. Where the fixing pack is not used
installers must ensure compatibility of their chosen fittings with the ¾"
BSP side valve connections, which are designed for use with hand
tightened plastic connectors. The lower port of each side valve should be
connected to a flexible hose to ensure that the unit is not installed under
tension. We recommend the use of shower pump flexible hoses or similar.
