3�0 INSTALLATION
Installation must only be attempted by competent
personnel.
3�1 POSITIONING AND AIRFLOW
The heat pump should be located in an open
space wi e maximum possible distance in all
directions to any obstructions. The heat pump should
not be covered by any structure or awning.
The heat pump works by absorbing energy from air
passing rough it so any restriction in e air flow will
reduce performance.
An obstruction is an object such as a wall, fence,
hedge or anying similar which may restrict e free
movement of air.
Obstructions can also cause exhaust air leaving e
heat pump to be sucked back into e heat pump
which will reduce performance.
Locating e heat pump near any obstructions should
be avoided if possible however if it is enclosed on up
to two sides by obstructions at e minimum distances
en e heat pump should perform as expected.
If e heat pump is enclosed on more an two sides
by obstructions at e minimum distances en e
performance will be reduced.
If ere are obstructions closer to e heat pump an
e minimum distances en e performance will be
significantly reduced.
A reduction in performance will result in longer pool
heat up times, e pool not reaching e desired
temperture and excess energy costs.
The diagrams show e minimum allowable mandatary
distances between e heat pump and any potential
obstuctions.
The heat pump should be fixed by M10 bolts to a level
concrete base or to solid mounting brackets which are
securely fixed. Fixings [including any brackets] must be
corrosion proof. Ensure e condensate connection is
made prior to securing e heat pump.
Airflow - general principles
• The heat pump absorbs energy from e air drawn
rough it. To function effectively e heat pump
must have access to e fresh air it needs.
• Air must not recirculate. The air leaving e heat
pump must not be sucked back into e inlet.
• Air must not be restricted. The air volume must not
be reduced.
• The minimum required distances shown must be
provided to minimise e risk of air recirculation or
restriction and reduction in performance. Examples
are shown on e following page.

IMPORTANT
Before installing e heat pump ensure e
blanking disks are removed from e pool water
in/out connections� These should drop out when
e adaptors are unscrewed�
1. Ensure at bypass is installed and set to achieve
e recommended flow rates stated in e data
sheet.
2. Ensure at e condensate drain kit supplied is
fixed and is drained to a drain or soak-away.
(It is best to do is first before e heat pump
is fixed to pipework or e ground)�
3. Inlet and outlet pipework must be supported to
avoid excessive strain on e connections.
4. Water quality must be maintained. See warranty
conditions.
3�4 INITIAL CHECKS
Start e filtration pump before e heat pump is
turned on, and turn off e heat pump before e

Electrolytic corrosion will occur when dissimilar metals
at are in contact wi each oer create a potential
difference between emselves. Sometimes separated
by a conductive substance known as an electrolyte, e
dissimilar metals will create a small voltage (potential
difference) at allows e ions of one material to pass
to e oer.
Just like a battery, ions will pass from e most positive
material to e more negative material.
Anying more an 0.3 volts can cause e most
positive material to degrade.
A swimming pool wi its associated equipment
can create is effect. The pool water being an ideal
electrolyte and components of e filtration circuit,
heating system, steps, lights etc providing e dissimilar
metals needed to complete e circuit.
Whilst ese small voltages are rarely a safety reat,
ey can create premature failure rough corrosion.
Not dissimilar to corrosion rough oxidation, electrolytic
corrosion can cause complete failure of a metallic
material in a very short period of time.
In order to prevent is type of corrosion all metallic
components in contact wi swimming pool water
should be bonded togeer using 10mm² bonding
cable. This includes non-electrical items such as metal
filters, pump strainer boxes, heat exchangers, steps
and handrails. It is highly recommended at bonding
be retrofitted to existing pools, which may not be
protected by is system.
All electrical work to be carried out in accordance wi
l.E.E. regulations, latest issue, or local codes of practice
as applicable.
The machine should be installed in accordance wi
EMC2004/108/EC.
Always isolate e main power supply before removing
machine covers.
The machine power supply must incorporate e
following. Fuses or motor type circuit breakers (aM
Fuse / MCB type C) to specified rating (see datasheet).
When using a fuse, H.R.C. fuses are recommended. An
isolator which disconnects all poles must be must fitted
wiin 2m and in line of sight of e heat pump. The
isolator must have a minimum of 3mm air gap when
turned off.
All units must be correctly eared/grounded and its
own separate type RCD ear leakage trip installed
which protects e machine only. See data sheet for
e correct type.
The following limits of operation must not be exceeded.
Failure to provide e necessary voltages will invalidate
e warranty. This voltage must be available at e heat
pump whilst running. The voltage must not drop below
e above figures when starting e compressor.

For installations where e pool filter pump runs
continuously, ese terminals do not need to be used.
For installations where a timeclock controls e pool
filter pump, and e same pump provides water flow
to e heat pump, e heat pump can override “pump
off” periods to ensure e pool is heated/cooled. To
activate is setting please speak to your installer.
When installed in parallel wi e timeclock, e pool
filter pump will run when:
a) a block period of “pump on” has been set on e
time clock for filtration purposes.
b) e heat pump runs e pool filter pump for
temperature sampling and if e pool subsequently
requires heating/cooling.
This feature operates by over-riding e timeclock for
3 minutes to circulate e pool water rough e heat
pump to sample e water temperature. The default
sampling time interval is 1 hour.
If e measured temperature is more an 1°C
from e set temperature, e point heat pump will
continue to run e filter pump and heat/cool e pool.
If e measured temperature is wiin 1°C of e set
temperature, e filter pump will turned off until e
next sampling period, or e next timeclock “pump on”
period.
When e pool pump is already running, and e
heat pump is not heating/cooling, e heat pump will
sample e water temperature once per hour and will
start heating/cooling if needed. The heat pump will
ignore a demand to heat/cool e pool until e
sampling timer (default 1 hour) has elapsed*.
This feature will reduce e pool filter pump run time to
minimise pump energy usage.
*If e pool filter pump is later changed to run
continuously, it is recommended to de-activate is
setting so e heat pump will respond to a heating/
cooling demand wiout waiting for e sampling time
interval to elapse. To deactivate is setting please
speak to your installer.
