In positive head systems, allow for increased
resistance of long pipe runs with multiple
bends. The natural flow from the shower
head or other outlets MUST be at least
1 litre/min per side (hot or cold).

Right whole House Pumps
(RHP)
Equipped with a bypass loop. Selection of
the Right whole house pump for a system
will be determined by the resistance of,
quantity of and the pressure required by,
the outlets.
In these systems
• Toilets MUST be tted with an equilibrium
ball valve.

ESP CPV pumps – system operation and
L.E.D. indication
With electronic system protection
ESP CPV pumps are the culmination
of four years intensive research
to develop advanced pumps
incorporating micro electronic
technology and sensors capable of:
• Positive or negative head operation
• Supply water temperature sensing
• Dry run protection
• Sensing chronic aeration or water
starvation
• L.E.D. indication of system function and
any unforeseen system malfunction
IMPORTANT NOTE
The HOT and COLD pump ends are identified
by RED (hot) and BLUE (cold) tie wraps.
See above illustration.

ESP CPV pumps have been designed
to protect customers by responding to
unexpected or unforeseen conditions.
ESP CPV pumps will only be switched ‘OFF’
if the unexpected or unforeseen conditions
are serious.
System operation and system malfunction
is indicated via five L.E.D’s located on top of
the pump junction box, see Figure 9.
For ESP CPV pumps only NON-RETURN
VALVES MUST NOT be fitted in the
discharge pipework between the pump
outlets and system outlets unless
specified by Salamander.
Either side of these pumps can be used for
hot or cold water.
