1.1 Controller s reen
Under normal operating conditions your LED screen should appear as below
(temperatures may vary.)
This controller has various timer functions that you will not need. You can set the date
and time, apart from this, all you need to set is your desired temperature with the arrow
buttons.

1.2 Cir ulation/filtration pump timer/ lo k
Setting the Time Clock (Guidelines only):
Time clock above illustrates auto mode with 12 daytime hours (between 9.00am and
9.00pm), n.b if the top slider switch is in the I position the filter pump will run
continuously, and in O will be off. There are many types and makes of timer; however
they all have this basic functionality. It is far better if you have or get fitted a timer with
a memory so that the settings do not shift after power interruptions.
It is recommended that for optimum filtration of an 8m x 4m or 10m x 5m pool with a
0.75 - 1.2 kW circulation/filter pump, the pump runs for 6 - 8 hours a day during the day,
i.e. from 10.00am until 6.00pm. This coincides with the optimum time settings for the
running of the heat pump too. As the ambient air temperature drops into the colder
months you may find that you need to increase the time that the circulation/filter pump
runs up to twelve hours to maintain the pool water temperature that you require.
Please note that in colder climates you may find that it becomes uneconomical to
maintain a high pool water temperature during the colder months, or that the
temperature loss is greater than the temperature gain provided by the heat pump. In
such cases you may decide that it is prudent to cease using your heater. Remember
during months where the outside ambient temperature drops to zero you must use the
by-pass and drain down your heat pump.

2. Installation.
Materials. To Install your Calyenty heat pump, you will need:
• x 50mm ball valves for the bye-pass.
• 2 x 50 mm pressure 90°elbow fittings.
• 2 x 50 mm pressure T fittings.
• Adequate 50mm pressure tubing (rigid or flexible).
• uPVC solvent and cement.
• Adequate 2.5mm x core flexible electrical cable.
You may find that you need some more pressure fittings or 45°elbows depending on
where you position the heat pump in relation to your existing installation.
2.2 Tools:
Tape measure, hacksaw, Philips screwdriver, Drill + m8 masonry bit, strap wrench.
Do not over tighten any water fittings; hand tight should be sufficient to ensure a good
watertight seal.

5
2.3 Where to put the heat pump in the hydrauli system:
The unit is generally installed outdoors (for indoor installation, please consult Calyenty).
Install the unit downstream of all pumps and filters and upstream of all chlorinators,
ozonizers and chemical pumps.
2.4 Multiple heat pump installations:

6
Where more than one heat pump is to be installed it is essential that they are connected
to the water system in parallel, see diagram below:
2.5 Installation Pro edure:

7
1. This unit should be installed by a competent person.
2. All electrical work should be carried out by a qualified electrician / lampista.
. Check packaging for obvious signs of damage, before installation begins. Report
any damage to Calyenty before installation if you have concerns.
4. Please read the Installation & Operation Manuals carefully before you install or
operate the unit.
5. The company will not be responsible should someone be injured in the event of
the proper installation procedures have not having been adhered to.
6. Choose a suitable location for your heat pump. Remember this must satisfy your
aesthetic requirements, should be close to the filter pump, be on flat ground
(unless positioned on a custom bracket), be in a sunny position if possible and
comply with the space requirements as illustrated:
The unit needs continuous fresh air while running. Please leave enough space around
the unit for unobstructed air absorption and discharging. Don't keep the unit in an
enclosed area, or the discharged cold air will circulate in the unit again and
consequently lower the heating efficiency.
7. Lift the heat pump into place onto the base.

8
8. The water is fed through the heat pump using the circulation/filter pump. You
will need to identify the return pipe from the filter to the pool (this is often
marked RETURN). You will now need to cut into this return plumbing / pipe work
of the pool system. Before you make this cut, make sure that if there are shut off
valves/taps in this pipe-work, and that they are in the closed position. USEFUL
TIP: If there are not any taps, it is possible to do this work without draining the
pool by inserting wine bottle corks into the return jets. IMPORTANT – Make sure
that the connection from the filter goes to the pipe connector on the heat pump
marked WATER INLET. Connect the pipe connector on the heat pump marked
WATER OUTLET to the return pipe that continues to the pool jets. See diagram
on page below to ensure that the pipe work is connected correctly as shown.
When making uPVC connections, it is very important that the surfaces of both
the pipe and the fitting are clean and dry. It is also very important to thoroughly
wipe the surfaces with the solvent cleaner, as this starts the chemical reaction to
ensure a good bond when the adhesive is applied. Make sure that the adhesive
covers 100% of both surfaces that are to come in contact with each other.
9. Connect the supplied control panel to the snap connecters to complete the
installation. The control panel must be mounted in a convenient dry place,
preferably inside, under a terrace roof is OK provided the controller is out of
direct sunlight.
10. We recommend that the heat pump is fitted within 8 meters (25 feet) of the
existing circulation pump for maximum performance. This is not critical but could
slightly reduce the efficiency of the unit if positioned further than this distance.
11. If the water in the heat pump is allowed to freeze it will damage the unit. It is
essential for the guarantee to remain valid to drain the heat pump during
months where the outside ambient air temperature can drop to 0°C. Simply
close the ball valve / shutoffs and open the bye-pass. Drain the unit by removing
the lower most water connector.
12. Please make sure that minimum water flow speed is m³/h.
1 . While the unit is running, water in the air may condense on the fins of the
evaporator. If the air humidity is very high, the condensation water within an
hour can be several gallons.

2.6 Conne ting to the ele tri ity supply:
IMPORTANT: Power supply to the filter pump, and the heat pump, and the switching on
and off of both devices must be the same and simultaneous. Using the electrical entry
marked “Power Supply” connect the heat pump to the dead side of the filter pump
timer clock electricity supply. Please ensure this is carried out be a qualified Electrician
or Lampista. It is important to give the heat pump power supply its own RCD circuit
breaker. N.B. Please check that when the power to the filter pump is cut or times out
from the timer, the power to the heat pump is also cut and the back lit LCD controller
switches off.
Make sure no power is supplied to the unit while connecting.
Always comply with the national and local electrical codes and standards.
In case any emergency occurs, the unit must be equipped with a breaker, which is
located within sight and accessible from the unit.
The unit must be well earthed.
Several screws fix the electrical component front panel cover to the cabinet. Unscrew
and remove the front panel to connect the power cable to the terminal marked POWER.
You can ignore the terminal marked PUMP. Also plug in the control panel cable. When
the connections have been made, replace this front panel very carefully. Make sure that
it is fixed firmly by the screws. It is vital that the PCB/terminal cover is replaced properly,
make sure that the edges of the cover are underneath the corresponding edges of the
heat pump body and the water tight seal is snug between the surfaces.
Mains connection
It is recommended that a qualified technician connects your heat pump to the mains.
2.5mm cable must be present in the pool house connected to a 25amp circuit breaker in
the house main fuse box provided that the run is no more than 25m. Any greater
distance you must run a new cable of at least 4.0mm.

3. Initial Startup
IMPORTANT: Make sure the by-pass is open and allowing sufficient flow of water to and
through the heat pump before switching power on
Notice: the unit will not heat the pool when the water circulation pump is not working.
The back lit controller screen will be blank.
3.1 Starting Steps:
Check whether the connectors, wires and cables of the unit, water pump, chlorinator,
ozonizer, chemical pumps and control panel are correctly coupled or connected.
Turn on the water pump and filter. Check for water leakage and verify the water flow.
Turn on the power of the unit. Then press the button ON/OFF on the control panel. All
Calyenty heat pumps have a variable start delay which can be from just a few seconds to
several minutes. This feature reduces load on your power supply which irrespective of
the electrical consuming device is always significantly more on start up. This feature
cuts down on power overload, ensuring the circulation pump and heat pump, or
multiple heat pumps never start at the same time.
After the unit runs for a few minutes, check whether the air discharged from the fan is
cooler than the ambient air as it should be.
Turn the water pump off while the unit is running. The unit should stop working
automatically. Turn on the unit again, set the temperature on the control panel and
keep the whole pool system running. The unit will stop running automatically as the
pool water reaches the set temperature. When the temperature drops to 1degree lower
than the set temperature, the unit will restart automatically.

5. Ba kwashing the pool/sand filter:
While the filter pump is running and the heat pump is switched on switch the heat
pump off by pressing the on/off button on the heat pump control panel. Switch the
filter pump off, close all taps to and from the pool so that you can remove and clean the
filter basket of leaves and any large debris. Replace the filter basket and replace the
cover and seal, re-open the taps that are normally open from the pool under normal
filtration conditions (skimmers and drain/fondo) and leave closed any return taps to the
pool and set the multi port selector valve to the position marked backwash. Check that
if there is a tap on the drain that this is open during backwashing. Switch the filter pump
on and leave running for approximately two minutes or until the water in the sight glass
is running clean. Switch the filter pump off and move the multi-port selector to the
position marked rinse. Switch the filter pump back on and rinse for a suitable period,
usually around a minute. Switch off the filter pump and re-open the taps back to the
pool return. Change the multi-port selector back to its normal filter position. Switch the
filter pump back on so that the pool is filtering normally. Check that the flow into the
pool via the return jets is its usual strength. Switch the heat pump back on with the red
on off button on the heat pump control panel.
6. Maintenan e and Troubleshooting
6.1 Maintenan e
General maintenan e:
The unit should be maintained by qualified technicians on a regular basis. Ask Calyenty
or your local dealer about our maintenance contract options.
A professional technician should clean the unit periodically. It is NOT recommended to
use a sprinkler to flush the unit.
The unit is designed to withstand normal rainfall. A flow of water into the inside of the
unit may damage the components (place unit away from garden sprinklers & watering
systems). If the unit is located under the eaves, ensure water does not flow directly onto
the unit.
• Clean the drain hose.
• Ensure a proper water flow:
• Keep the filter clean. The filter may get dirty along with use. A dirty filter can
reduce the water flow.

14
• Keep the pump clean.
• Check the valves often
6.2 Troubleshooting
The unit would not run.
Is the screen of control panel lit? If not, ensure the electrical wires and cables are
correctly connected and the power is on.
If the screen displays E5, check the water flow. Whether the water pump is running
normally or the filter is jammed?
The unit will stop running automatically when the pool water reaches the set
temperature.
The unit is running but not heating.
Is the air discharged from the fan cooler than the ambient temperature? If not, ask a
professional technician to check the refrigerant system.
Be sure the space around the unit is broad enough. There should not be obstruction of
air.
Environment problem
Under certain external conditions the heat exchanges between the refrigerant and the
water on one hand and between the fluid and the air on the other hand are insufficient;
the consequence is that the refrigerating circuit runs up in pressure and the compressor
consumes more electricity.
The temperature sensors compressor outlet and the magnetic circuit breaker on the
compressor power supply protect the compressor from these extreme conditions.
The condition causing this situation is as follows:
In heating mode:
- Insufficient water flow:
close the by-pass valve for increasing the refrigerant exchange  water
In cooling mode:
- Too important water flow: open the by pass valve for decreasing the water flow and so
the exchange water  refrigerant
- Insufficient air flow: be sure that the real net of condenser is not blocked.

8 Defrost Control
Defrost Cut-in Conditions: only when the following two onditions are satisfied:
1.Compressor continuous running time ≥ Defrost Cut-in Time (P2)
2. Evaporator Coil Temperature ≤ Defrost Cut-in Temperature (P )
When the unit enters defrosting mode, the 4-way reversing valve will de-
energize, directing the hot gas to the evaporator coil. The fan motor will
stop but the compressor and pump will continue working.
Defrost Cut-out Conditions: when either of the following onditions are
satisfied:
a. Evaporator Coil Temperature ≥ Defrost Cut-out Temperature (P5)
b. Defrosting time ≥ Defrost Cut-out Time (P4)
When the unit reverts to heating from defrosting mode, the 4-way
reversing valve will energize and the fan motor will begin to work.
For ed Defrost:
When the unit is in standby state, hold Arrow Down button for five seconds
will lead to forced defrost function.
After any Defrosting the unit will exit defrost state.
