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: Model3GEO -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.

Water fl ow (m3/h - l/s)
This graph indicates the drop in the pressure of the water in the hydraulic air conditioning circuit (components
inside the unit), including plate heat exchangers, water fi lter, pipes and water hose connection.
The air conditioning pump to be installed outside the unit must be chosen by the installing technician based on
nominal cooling and heating fl ows, on drops in the internal pressure of the unit as indicated in the graph, and
on the drop in pressure expected in the installation itself.

- Wear safety goggles and gloves while working. Use quenching cloth during operations welding.
- Put in place strong units that can support the weight bearing and allow the right posterior maintaining it.
- Use the specified cables and make a proper connection at the terminals.
- Make a separate attack unit.
- Check the supply voltage corresponds to the plate.
- Perform the corresponding ground.
- Perform the work safely install hydraulic and drainage pipes as shown of this manual.
- During operation of the drive circuit part5s refrigerant.(compressor line download) can reach temperatures.
inside the unit.
- The unit can work in environments "normal" residential, commercial or light industry. The unit can not be installed in
explosive atmosphere environment. For applications Special should consult the manufacturer.
Very important!
Before starting the installation or maintenance operations of the unit disconnect switch general power. Electrical
shock can cause personal injury.

9. INSTALLATION
9.2 LOCATION OF UNITS
Inspect units of receipt to verify any damage or damage during transport. If the unit is damaged you must file a claim
immediately to the company who made the shipment.
Interior Location of Unit
The indoor unit is designed for installation inside the
housing. For this, the inner cabinet has the same action at its base
that a common household. It also has the possibility of
adjust its height due to small height-adjustable feet.
When installed inside the unit must be left open the door area
access, being necessary to leave the spaces described in paragraph
7 (Service Areas).
Location of Outdoor Unit
The outdoor unit must be placed in proper orientation to
climatic characteristics of the region where it is installed.
It should be positioned so that air circulation is free and well
avoid recirculation effects detrimental to performance.
When installing the outdoor unit must be left free the front of the
unit, which is necessary to leave the spaces described in paragraph 7
(Service).

Hydraulic Circuit Climate
- Water pump
The operation of closed circuit cooling, means that water must be transported heating or cooling energy from the unit Triaqua to
secondary and this installation is performed by forced circulation water pump.
.
This water pump must be placed by the installer and should be calculated for water flow required and to overcome the pressure drop
(installation + machine) .See section 8
For electrical connection, see Section 9.4 (Electrical Connections).
IMPORTANT: A small pump may cause a malfunction or even a fault irreparable.
- Flow Switch
IMPORTANT: The water shortage could cause irreparable damage to the unit.
- Differential pressure valve
To ensure that water always returns to the unit in the cooling circuit,install a differential pressure valve. The differential pressure
valve guarantees the minimum flow required for proper functioning of the heat pump when there is closure of the thermostatic
valve and limits differential pressure of the installation.
IMPORTANT: If water does not return the unit, it could cause an irreparable damage to that unit.

To avoid potential problems in the unit for lack of water in the cooling circuit, the unit incorporates a flow switch.

- Perform opening the water inlet tap the network of the unit (see Fig.5.1)
- Open tank trap DHW (Fig.5.2) and the bleeder on the top of the water pipe connecting the heat exchanger climate with
DHW (Fig. 5.3). Close both traps when you stop air and water comes out.
- Open a point of hot water consumption to flush the system.
- The indoor unit includes a pressure regulating valve (factory calibration 2.5 Bar). If

Filling and Pressure Testing Air Conditioning Hydraulic Circuit
-To fill water cooling tank, proceed as follows:
- Ensure that the secondary installation, underfloor heating, fan-coil, etc, has previously been filled and purged.
- With the tap water inlet of the unit open network (1) Fig.5.1, open the manual filling key

- Open the manual trap located at the top of the cooling tank and keep it open until all air is removed from the
circuit (Fig.6.3).
- Secondary installation should incorporate a trap in the top. Open the trap if necessary.
- Having gained the venting unit, shut off the circuit manual filling air conditioning (Fig.6.1), the keys must be cut
(and out) of the cooling circuit open.
- Check the cooling circuit pressure on the gauge installed in the control panel indoor unit, must be between 1 and
2.5 bar (normal 1.5 bar) for proper operation.
- Ensure that all secondary facility is found with water pressure and completely purged of air. The existence of air
in the cooling circuit can cause irreparable damage unit. It is becoming essential to make a proper venting cooling
circuit of the installation. For this reason, traps will be installed in the highest part of the circuit housing proceed to
remove all air from the facility in an appropriate manner..

9. INSTALLATION
- It is recommended to connect the cooling pump directly to the network, ie, pump-only
time,to eliminate the existence of such air circuit.
Attention!
Do not connect the unit for operation of the pump. When connecting the unit and not the water pump
independently, it could cause irreparable damage in the unit.
- The unit has air conditioning in the circuit (return) a mesh filter (Fig-7), whose mission is
which might remain in the cooling circuit of the house.

Attention!
The dirt from the installation may cause irreparable damage to the unit.
- Once the connections and filling, and prior to starting the unit, it is recommended operating the air conditioning
circuit pump for a while, to retain the mesh filter particles and impurities that could be installed. To this should be
wired air conditioning pump directly to the network.
- Once that is done, and the pump stopped, it should close the stopcocks input and output conditioning circuit
(Fig.6.2), drain water tank cooling through the same drain and clean the filter screen. Then fill again circuit.
- To ensure that no dirt on the circuit, should make this operation as often as necessary.
- Having established that the cooling circuit is clean, insert glycol, if necessary, approximately 20%.
- Should perform periodic reviews, including cleaning the filter screen, to ensure that there is no dirt inside the
circuit.
