8. AIR CONDITIONING WATER PUMP
AIR CONDITIONING WATER PUMP
The selection of coolig water pump to be mounted by the installer out of the unit should take based on the flow rates
of cooling and heating,internal drop unit (see graph) and the drop of the facility.
Calculation of nominal water flow:
Q water (l / h) = Cooling Capacity* 0.86 (Kcal / h) / △T (º C)
As △T = (T first exit water temp - water return Temp) _T = 5 º C
Example: Model 3AQUA-15
Q water = (16,300 W * 0.86) Kcal / h / 5 ° C = 2800 l / h
IMPORTANT: The temperature difference in air conditioning heat exchanger should be 5 º C approx.A high temperature
difference can cause a malfunction of the unit and even irreparable damage to it.

9. INSTALLATION
9.1 SAFETY CONSIDERATIONS
A series of recommendations to follow for correct installation of the unit are included below.
The installation, repair and maintenance of these units must be performed with caution because of the presence
of electrical and electronic components and because of the pressure system of the refrigerant circuit. Only
trained and qualified personnel should perform installation, adjustment and maintenance operations on the
unit.
The manufacturer declines all liability in the event of negligence or the failure to follow the safety rules described
below:
- Work under completely safe conditions, free from obstacles and in a clean environment.
- Respect legislation in force.
- Before starting up the unit, confirm that both the unit and its components are in perfect condition.
- Use safety goggles and gloves when working. Use a fireproof blanket during welding operations.
- Position units on firm ground that supports the load weight and that allows maintenance to subsequently be
performed correctly on the same.
- Use the specified cables, and make the correct connection to terminals.
- Provide an independent power supply connection for the unit.
- Verify that the supply voltage corresponds to the voltage on the specifications plate.
- Make the corresponding earth connection.
- Safely perform the installation work of the hydraulic and drainage lines according to the instructions in this
manual and according to legislation in force.
- When the unit is operating, some parts of the refrigerant circuit (compressor and discharge line) can reach
temperatures exceeding 70º C. Be especially careful when accessing the interior of the unit.
- The unit can work in "normal" environments of residential, commercial or light-industry installations. The
unit cannot be installed in an explosive atmosphere or an atmosphere that is aggressive to the unit's
components. For special applications, the manufacturer must be consulted.
Very important!
Before beginning any installation or repair operations on the unit, turn off the main electric power supply
switch. An electric shock can cause personal injury.
18
9. INSTALLATION
9.2 LOCATION OF THE UNITS
Inspect the units when they are received to verify that no damage has occurred during transport. If a unit is
damaged, a claim must be submitted immediately to the company that made the delivery.
Location of the Indoor Unit
The indoor unit is designed to be installed inside a home. Therefore,
the indoor unit has the same measurements at the base as those of a
common electrical appliance. The height can also be adjusted using
small, adjustable legs.
When the indoor unit is installed, the area around the access door must
be left free. The spaces described in section 7 (Service Space) must also
be left free.
Location of the Outdoor Unit
The outdoor unit must be installed with an orientation that is suited to the
weather characteristics of the region where it is installed. In case of doubt,
consult the manufacturer.
It must be installed so that air circulates freely, thereby preventing the
effects of re-circulations, which can reduce the unit's performance.
When the outdoor unit is installed, the area around the front of the unit
must be left free. The spaces described in section 7 (Service Space) must
also be left free.

The unit is equipped with flexible hoses to facilitate the hydraulic connections of the air conditioning circuit
(Figure 3).
Figure 3

9. INSTALLATION
The common intake must be led from the safety valves of the two tanks to the drain (Figure 4).
Figure 4
Outlet to drain
Air Conditioning Hydraulic Circuit
- Water pump
The operation of the closed air conditioning circuit means that water carries the heating or cooling energy
from the Triaqua unit to the secondary unit of the installation. This forced circulation is performed by the water
pump.
This water pump must be installed by the installer and must be calculated to meet the required water flow rate
and to be able to overcome the head loss (installation + machine). See section 8.
For its electrical condition, see section 9.4 (Electrical Connections).
IMPORTANT: A pump that is too small could cause inadequate operation or even irreparable damage.
- Water Flow switch
It is essential to ensure that there is a minimum flow of water in the air conditioning circuit. It is therefore
necessary to install a flow switch to protect the machine.
The indoor unit comes prepared for the electrical condition of the flow switch (WT-WT connections) (terminals
17 and 18).
Figure 5
The bridge between those terminals must be removed, and the flow switch must be connected to them.
IMPORTANT: Insufficient water could cause irreparable damage to the unit.
21
9. INSTALLATION
- Differential pressure valve
In order to ensure that water always returns to the unit on the air conditioning circuit, a differential pressure
valve must be installed. The differential pressure switch guarantees the required minimum flow rate for proper
operation of the heat pump when the thermostatic valves close, and it limits the differential pressure of the
installation.
IMPORTANT: If water does not return to the unit, it could cause irreparable damage to the unit.
Filling the hydraulic circuits and checking pressures
Very important!
In order to fill the hydraulic circuits, proceed in the order indicated below.
1. Filling the DHW secondary circuit. (DHW plate exchanger - DHW tank).

- Open the water inlet valve of the unit's network (see Figure 6)
- Open the air bleed of the DHW tank (Figure 7). Close this air bleed when air stops coming out and water
does.
- Open any DHW consumption point to bleed air from the installation.
- The indoor unit incorporates a pressure regulator valve (factory-rated to 2.5 bar). If necessary, adjust the
water inlet pressure to the unit (normally 2.5-3 bar).
- Check that the DHW pump rotates in the correct direction by accessing the shaft of the same through the
maintenance screw.
Figure 7

9. INSTALLATION
2. Filling of the air conditioning circuit (air conditioning plate exchanger - air conditioning buffer tank).
- Be sure that the circuit to be climatised (radiating floor, fan-coil, etc.) has previously been filled and bled.
- Keep all water inlet and outlet shut-off valves closed (Figure 9).
- With the water inlet valve of the unit's network open (1), Figure 6, open the manual fill valve of the air
conditioning circuit (Figure 8).
- Open the manual bleed located at the top of the air conditioning tank, and keep it open until all the air has
been eliminated from the circuit (Figure 10).

9. INSTALLATION
- Once the air has been bled from the unit, close the air conditioning fill valve (Figure 8), and use the pressure
gauge installed on the unit's control panel to check that the pressure of said circuit is around 1.5 bar.
3. Filling of the primary DHW circuit (DHW plate exchanger - air conditioning plate exchanger)
- Open the air bleed of the primary DHW circuit (Figure 11).
- Connect the electric power supply to the indoor unit, WITHOUT TURNING THE UNIT ON, and select
the DHW operation.
- The 3-way water valve of the air conditioning circuit activates and begins to fill said primary DHW
circuit (hydraulic circuit between the plate exchangers).
- When water comes out through the air bleed of this primary DHW circuit, close the air bleed and
disconnect the electric power supply to the indoor unit.
- If it were necessary, fill the air conditioning hydraulic circuit with water. Open the fill valve of said
circuit (Figure 8). Keep the pressure around 1.5 bar.
- Open the shut-off valves (inlet and outlet) of the air conditioning circuit (Figure 9)
- Use the pressure gauge installed on the control panel of the indoor unit to check the pressure of the air
conditioning hydraulic circuit (normal is 1.5 bar).
- Be sure that the entire installation of the circuit to be air conditioned has water pressure and is
completely bled of air. The existence of air in the air conditioning circuit could cause irreparable
damage to the unit. It is essential to adequately bleed the air conditioning circuit of the installation. To
do so, air bleeds will have been installed at the highest part of the home's circuit in order to suitably
eliminate all air in the installation.
- It is advisable to connect the air conditioning pump directly to the network - meaning only the water
pump of the air conditioning circuit - for a period of time in order to eliminate any air in said circuit.
Attention!
Do not turn on the unit to operate the water pump. If the unit is turned on while the pump is running to bleed
air from the air conditioning water circuit, irreparable damage could be caused to the unit.
24
9. INSTALLATION
Water filter (air conditioning circuit)
- The unit has a mesh filter (Figure 12) on the air conditioning (return) circuit, and its mission is to retain
particles or dirt that could remain in the home's air conditioning circuit.
Figure 12
Attention!
Dirt in the installation could cause irreparable damage to the unit.
- After making all the connections and after filling the circuit, and before turning the unit on, it is advisable
to turn on the pump of the air conditioning circuit for a period of time in order to retain any particles and
impurities that could be in the installation. To do soy, the air conditioning pump has to be connected directly
to the network.
- Once this operation has been performed, and with the pump stopped, the inlet and outlet shut-off valves of
the air conditioning circuit (Figure 9) must be closed, the water must be drained from the air conditioning
tank through its drain, and the filter's mesh must be cleaned. Afterwards, the circuit will be filled again.
- In order to be sure that there is no dirt in the circuit, it is advisable to perform this operation as many times
as necessary.
- After having checked that the air conditioning circuit is clean, fill it with glycol to approximately 20% of the
total volume of the installation.
- It is advisable to make periodic checks, which includes cleaning the filter's mesh, in order to be sure that
there is no dirt in the circuit.
Water treatment
It is advisable to install a filtering system (water softener, etc.) to prevent the build-up of lime and other minerals
from the water on the pipes or on some components of the unit. This will prevent damage to both the installation
and the unit itself.
Likewise, it is advisable to perform periodic maintenance on the installation and unit.

VERY IMPORTANT! PROTECTION AGAINST INDIRECT CONTACTS.
The installer must protect the unit's electric power supply line using automatic disconnection devices, a
circuit breaker and a residual-current device that are suitable for the installation and in accordance with
legislation in force.
Because the unit incorporates an electric heater, it must be kept in mind when sizing the power supply
line of the indoor unit.
The unit's power supply cables cannot be lighter than ordinary, flexible polychloroprene sheathed cable
(H05 RN-F designation).
Starting up the unit using an incorrect voltage line is not covered by the TriAqua warranty. Pay special
attention to connecting the earth protection cable. It should be the first cable connected, and its length
must be greater than that of the live cables.

9. INSTALLATION
9.5 REFRIGERANT CONNECTIONS
General considerations
The refrigerant lines will be interconnected as follows:
- The indoor unit has the gas and liquid intakes identified with stickers as follows:
Gas line: Gas (refrigerante)/Gas (refrigerant)
Liquid line: Líquido (refrigerante)/Liquid (refrigerant)
- All the refrigerant connections, just like the water connections, are threaded.
- The lines have to be insulated to prevent condensation and thermal losses.
- Once the lines have been installed, apply a vacuum to the refrigerant circuit of the indoor unit until a
pressure of -1 Kg/cm2 is reached for at least 2 hours.
- The refrigerant circuit can be emptied and the refrigerant can be charged through the service valves located
on the right side of the outdoor unit.
- Check that there are no leaks on the refrigerant circuit.
Connection between units
On the indoor unit:
The indoor unit is equipped with couplings for screwing on the connections. Take the lines to the outlet zone
of the connections on the indoor unit (see the schematic in section 6. Dimensions), and make the connections
there.
The indoor unit leaves the factory with a dry nitrogen charge. The refrigerant lines of the indoor units are
factory-fitted with adapters and nuts to guarantee a perfect seal until use.
On the outdoor unit:
The outdoor unit leaves the factory with a charge of R-410A refrigerant that is valid for a line length equivalent
to a maximum of 5 metres. For lengths greater than 5 metres, a charge must be added according to the table
in section 9.7.
Gas valve and liquid valve coupling

9. INSTALLATION
9.6 APPLYING THE VACUUM TO THE REFRIGERANT INSTALLATION
After making the refrigerant connection between the indoor and outdoor units, and after having checked the
seal of the connection, a vacuum is then applied to the unit, for which the process below will be followed:
- With the service valves of the outdoor unit closed (as the unit is delivered from the factory), remove the caps
from said service valves.
- Connect the pressure gauge manifold as follows:
s4HEBOTTOMINTAKEOFTHEPRESSUREGAUGEMANIFOLDTOTHEGASSERVICEVALVE
s4HETOPINTAKEOFTHEPRESSUREGAUGEMANIFOLDTOTHELIQUIDSERVICEVALVE
s4HECENTRALINTAKEOFTHEPRESSUREGAUGEMANIFOLDTOTHEVACUUMPUMP
- Start the pump and open the valves on the pressure gauge manifold to
ensure depressurisation of the
refrigerant circuit on both refrigerant lines and to the indoor unit.
- Apply vacuum until it is assured that the pressure gauge on the manifold
indicates -1 bar.
- After applying the vacuum, close the valves of the pressure gauge manifold,
and turn off the vacuum pump, and assure that the vacuum pressure is
maintained for at least 15 minutes.
- If the pressure does not remain stable, it means that there is a leak in the
circuit, which will have to be located and fixed. After fixing it, repeat the
Manometer pressure
preceding steps.
- If the vacuum pressure remains stable (refrigerant could now be charged,
if it were necessary), disconnect the intake from the pressure gauge
manifold of the first vacuum pump, and keep the pressure gauge manifold
closed, with the ends connected to the service valves or to the lines, as
Low
High
applicable according to each model.
- The outdoor unit leaves the factory with a charge of R-410A refrigerant
that is valid for a line length equivalent to a maximum of 5 metres.
- Open the service valves.
- For line lengths of greater than 5 metres, re-charge the unit according to
Vaccum Pump
the refrigerant re-charge table.
NOTE:
- To recover the entire refrigerant charge in the outdoor unit, close the liquid valve. The pressure is reduced to 0 Pa.
Afterwards, close the gas valve.

14. MAINTENANCE
Before starting any maintenance or cleaning operation on the unit, be sure that the main power switch is
disconnected and that no current reaches the same.
Ordinary maintenance
This section is designed for the end user. It is very important for maintaining regular operation of the unit over
time. Just a few operations, performed periodically, can prevent a necessary call to service personnel.
The necessary operations do not require specific technical knowledge, and in brief, they are simple checks of
some of the unit's components.
- Cleaning of the outdoor tube bank: The tube bank must be in good condition to maximise the thermal
exchange. It is therefore necessary to keep the surface free of the dust and dirt that may become deposited
because of the fans.

- Control of the defrost water flow: When operating in winter, frost can appear on the exterior tube bank. It is
necessary to check that the drain is not obstructed.
If drainage is bad, a layer of ice could form on the base because of cold temperatures, which would compromise
the operation of the entire system.

15. SOLAR SYSTEM CONNECTION
Application 1 (Standard)
Connected with dual coils solar system. Solar preheating can be used for D.H.W and room heating in the same time.
Automatic solar assistant Fuzzy Logic control program built inside to save cost the
mostly.
- Our heat pump inner system can compare the solar tank temp and room heating returned water temp. the returned
water will go through solar tank if it can get extra heat from solar heating. If in cloudy day, the returned water may
not go through solar tank to avoid heat loss.
- For summer cooling circuit, inner program will always shorten the 'cooling' circuit automatically as it no need heat.
- Domestic hot water will always go through solar tank to be preheated.
So the heat pump can have a good rest in sunny day to save cost and work more in
cloudy day. Especially excellent for floor heating together with hot water application.
to DHW
Single way valve
Note:
To make sure the above application working well, note the following procedure
1. Check the indoor wiring diagram in page38 for G2 port and solar water tank sensor location.
2. Solar automatic control 3 way valve(220V) need to be connected to G2 port of indoor PCB
3. Solar tank sensor from indoor PCB need to be put in the middle of the solar water tank and should be located
above the solar coil as shown above diagram.
4. Solar system need to be connected with lower coil of water tank ; air conditioning water system need to be
connected with upper coil of water tank.

15. SOLAR SYSTEM CONNECTION
Application 2 (optional- need special requirement for Triaqua inner DHW coil when placing order)
Solar panel or vaccum pipe is directly connected with Triaqua heat pump inner D.H.W water tank coils. The inner
recycle fluid can be brine to avoid freeze in winter. It can save one solar water tank cost.
Application 3
Connected with normal mono type solar system with water tank together with solar vaccum pipes. Applicable for

Better to print this page out and make sure that you can tick all of the following items to avoid any problem
After finish the installation tasks, please check the items listed below before turn on Triaqua heat pump
T hings you should have done:
1. Power cable
Check if the power cable is connected correctly, and check if the screws have been screwed
down and tight. Please use specified cables.
2. Communication wire
Check if the communication wire is connected correctly, and check if the screws have been screwed
down and tight.Please adopt specified communication wire.
3. Water circuit
-a. Check if the water pipe s are correctly connected, and the pipe dimensions are correct.
-b. Check if all the shut off valve and manual valve is opened, check if all the joint is fastened.
-c. Check if air exhaust valves on the water terminals must be open for the 1st water recycle running
to exhaust air in the terminals.This valve can be closed when this valve drain continous water.
-d. Check if air exhaust valves for the whole water circuit is openned. An automatic purging device
has to be installed at the highest point of the water circuit.
-e. Open the maintenance screw in the middle of the water pumps(for both DHW and air conditioning
circuit) and manually rotate the water pump axis. This action should also be done when electric
