To set the pump in Negative head:
1 Turn off the power to the pump, then
turn it back on.
2 The pump will run showing an amber
light (L.E.D.) then will stop.
3 Wait until a green light shows on the
pump and turn the power off for
5 seconds.
4 Turn the power back on to the pump.
5 The pump will repeat this sequence but do
not turn off the pump, at the end of the
sequence the green light will flash then go
off and then come back on and stay on.
6 The pump has now been set in
negative head.
An ESP pump is capable of operating in positive or negative head.
Should you need to
switch from one to the other please follow the instructions below:
Negative head operation
– Green L.E.D. ON
Positive head operation
– Amber L.E.D. ON
HUNTING PROTECTION
Only after two (2) hours of persistent
ON OFF ON OFF hunting due to a
dripping (tap or shower) outlet.
DRY RUN PROTECTION
Only occurs in instances of chronic
aeration or water starvation after
(2) ON OFF ON OFF operation and
a 60 second recovery period.
EXCESSIVE TEMPERATURE
Due to the hot water temperature
exceeding acceptable limits. The
pump will automatically reset to
operate when the water temperature
returns to normal.

ESP CPV pumps (positive head)
ESP twin pump to a whole house system. In
these systems TOILETS must be fitted with
equilibrium ball valve(s).
Figure 11: Positive head
Negative head systems
Negative head systems are those where the
shower head or other outlets are above or
are level with the cold water storage tank,
or when the low head pressure does not
provide enough natural flow to the outlet.
Salamander positive head pumps require a
natural flow of only 1 litre per 30 seconds
per flow switch. Negative head systems
are typically loft conversions or flats with
showers which have self-contained hot and
cold water services. See Figure 10.
Fully automatic negative head systems are
best accommodated by using an ESP CPV
pump (the fully integrated option which
has a built-in pressure vessel and electronic
system protection).
The requirements of large systems including
multiple body sprays and or boosted supplies
to two or more bathrooms are best served
with Right ESP CPV Super Booster with
integral pressure vessels. See Figures 16, 17
and 18.
ESP CPV
ESP CPV pumps can be commissioned to
operate in negative or positive head. The
correct procedure for commissioning is
therefore extremely important.
ANY RED L.E.D. ‘ON’ indicates PUMP OFF indicating unforeseen
system malfunction
To set the pump in Positive head:
1 Turn off the power to the pump, then
turn it back on.
2 The pump will run showing the amber
light then will stop – switch it back off
immediately.
3 Wait 5 seconds then turn the pump
back on.
4 The amber light will come on and go back
off again. The green light will come on
and go back off again. Finally, the amber
light will come back on and will remain
on and the pump is now in positive head.
