5INSTALLATION
WARNING: All the operation described in next chapters MUST BE DONE BY TRAINED PEOPLE ONLY. Before any
operation on the unit, be sure that the electric supply is disconnected.
5.1 GENERALITY
When installing or servicing the unit, it is necessary to strictly follow the rules listed in this manual, to conform to all the
specifications of the labels on the unit, and to take any possible precautions. Not observing the rules reported on this manual can
create dangerous situations.
After receiving the unit, immediately check its integrity. The unit left the factory in perfect condition; any eventual
damage has to be questioned to the carrier and recorded on the Delivery Note before signing it.
The company has to be informed, within 8 days, of the extent of the damage. The Customer should prepare a written statement of
any severe damage.
WARNING: The units are designed for outdoor installation. The place of installation must be entirely far away from
fire risk. All the necessary measures should be adopted in order to prevent the fire risk in the place of installation. The
outdoor ambient temperature shall not exceed 46°C. Above this value, the unit is no longer covered by the directives
in force in the area of pressure equipment.
WARNING: The unit should be installed so that adequate clearance is available for maintenance and repairation. The
warranty does not cover costs related to platforms or handling equipment necessary for any maintenance.
All maintenance and testing operations should be carried out only by QUALIFIED PERSONNEL.
Before any operation on the unit, make sure the power supply is disconnected.
WARNING: MOVING PARTS, RISK OF DEATH.
Disconnect the power supply and ensure that the fan is stopped before opening the front panel.
The temperatures of heads and discharge piping of the compressor are usually high.
Be careful when working near condensing coils.
The aluminum fins are very sharp and can cause serious injuries.
After the maintenance operations, close the panels tightly with the fastening screws.
5.2 LIFTING AND HANDLING
When unloading and installing the unit, it is highly recommended to
avoid any sudden move in order to protect the inner components.
Units can be lifted by means of a forklift or, in alternative, of belts,
being sure not to damage the lateral panels and the cover. It is
important to keep the unit horizontal during these operations.
5.3 LOCATION AND MINIMUM TECHNICAL CLEARANCES
The all HP_OWER units are designed for outdoor installation: any cover over the unit and location near trees (even if they partially
cover the unit) has to be avoided in order to prevent air recirculation. It is advisable to create a proper basement, with a size
similar to unit foot-print. Unit vibration level is very low: it is advisable however, to fit a rigid rubber band between basement and
unit base-frame. It is also possible to install anti-vibration supports (springs or rubbers) to keep vibrations at a very low level.
Absolute care has to be taken to ensure adequate air volume to the condenser. Re-circulation of discharge air has to be avoided;
failure to observe this point will result in poor performance or activation of safety controls. For these reasons it is necessary to
observe the following clearances:

5.4 HYDRAULIC CONNECTIONS
The hydraulic connections have to be installed in accordance with national and local regulations; pipes can be made up of steel,
galvanized steel or PVC. Pipes have to be designed depending on the nominal water flow and on the hydraulic pressure drops of
the system. All pipes have to be insulated with closed-cell material of adequate thickness. Chillers have to be connected to piping
by means of flexible joints. Piping should include:
•Hole thermometers to monitor the system’s temperature.
•Manual gate valves to separate the chiller from the hydraulic circuit.
•Y-shaped metallic filter (to be mounted on the inlet pipe) with a mesh not larger than 1mm.
•Charging group and discharge valve, where necessary.
WARNING: Make sure that, when designing the pipe length and diameter, do not exceed the maximum head loss
on the plant side, please see the technical data given in the table of Paragraph 12 (available pressure head).
WARNING: Connect the pipes to the attacks by using always key against key system.
WARNING: The expansion vessel have a limited volume. The installator have to provide a further expansion vessel
if it is necessary.
WARNING: Unit water inlet pipe have to be in correspondence with the connection labelled: ”WATER INLET”,
otherwise the evaporator may freeze.
WARNING: It is compulsory to install on the WATER INLET connection a metallic filter with a mesh not larger than
1mm. Should the water flow switch be altered or should the filter not be installed, the warranty will no longer be
valid. The filter have to be kept clean, so make sure it is clean after the unit has been installed, and then check it
periodically.
All units are standard supplied with the water flow switch (factory installed). Should the water flow switch be
altered, removed, or should the water filter not be installed on the unit, the warranty will be invalidated. Please
refer to the wiring diagram for the water flow switch electric connections.

The INVERTER system allows to reduce the plant’s water content to the minimum, that is from the usual value 12-15 l/kW to 18
liters for the 6kW model or to 25 liters for the 9kW model or to 35 liters for the 12kW model and to 45 liters for the model
15kW, in ABSOLUTE,. Because of the reduced water content, the HP_OWER units can be also installed in plants without water
tank with advantages in terms of the appliance’s reduced size, the installation space, heat loss and installation and
maintenance costs.
5.4.1 Drainage connection
All HP_OWER units have been designed to use their own base as a drain pan; a plastic pipe fitting is standard provided to be
installed onto the lower part of the unit in the special housing enabling the connection of a drainage pipe.
Each unit is also provided, on the basement of the hydronic kit (accessible from the right sides panels), with a hole that can allow
to drain any condensation that may escape from plumbing pipes. As well as the pipes are well-insulated, the production of
condensate is however very low and therefore the connection of a drainage pipe to that hole is not required.
5.4.2 Plant circuit charging
WARNING: Verify all the charging/topping up operations.
WARNING: Before beginning the charging/topping up operation of the plant circuit, disconnect the unit for the
electric power supply.
WARNING: The charging/topping up of the plant circuit must always be done under controlled conditions of
pressure (max 1 bar). Make sure that you have installed on the line of charging/topping up a pressure
reducerdevice and a relief valve.
WARNING: The water on the charging/topping up pipe must be suitably pre-filtered from any impurities and
suspended particles. Make sure that you have installed a cartridge filter removable.
WARNING: Before beginning the charging /topping up operation, unscrew the plug of the air vent valve. Tighten
the plug after finishing the operation of charging/topping up of the plant circuit system.
5.4.3 Plant drainage system
When it is necessary to drain the plant, close at first the inlet and outlet manual gate valves (not supplied) and then remove the
pipes that are disposed externally on the water inlet and on the water outlet in order to spill away the liquid contained in the unit
(for easier operation, it is recommended to install externally two draining valves, on the water inlet and on the water outlet,
between the unit and the manual gate valves). You also need to connect a hose to the service valve and make sure to fully
discharge the heat exchanger by the mean of the knurled nut .

During the operations of charging/topping up, the plugs of the air vent valves must
be partially unscrewed to allow air to flow freely out of the valves.
(1) Plug of the air vent valve
You can use the service valve, when it is necessary to refill the plant or adapt the
concentration of glycol. Unscrew the cap of the service valve and connect to the
hose a pipe of 14 mm (inner diameter) connected to the water network, and then
load the system by unscrewing the knurled nut. When the operation is concluded,
retighten the knurled nut and screw on the cap. In any case, we recommend you to
use for the water loading of the plant an external tap whose arrangement is by the
installer.

6START UP
Before start-up:
Check out the availability of the supplied wiring diagrams and manuals of installed apparatus.
Check out the availability of the electrical and hydraulic diagrams of the plant in which the unit is installed.
Check that the shut-off valves of the hydraulic circuits are open.
Verify that the hydraulic circuit has been charged under pressure and air vented.
Check out that all water connections are properly installed and all indications on unit labels are observed.
Ensure that arrangements have been provided to drain the condensate.
Check out that all power cables are properly connected and all terminals are hardly fixed.
Check that electrical connections are carried out according to the norms in force including grounding.
Check out that the voltage is the one shown in the unit labels.
Make sure the voltage is within the limits (±10%) of tolerance range.
Check out that crankcase heaters are powered correctly.
Check out that there is no refrigerant leakage.
Check out that all the cover panels are installed in the proper position and locked with fastening screws before start up.
WARNING: The unit must be connected to the electrical network and should be in STAND-BY mode (powered) closing
the general switch in order to operate the crankcase heaters of the compressor for a minimum of 12 hours before
start up. (the heaters are automatically powered when the main switch is switched off). The crankcase heaters are
working properly if, after some minutes, the temperature of crankcase’s compressor is about 10°C ÷ 15°C higher than
ambient temperature.
WARNING: The weight of the pipes doesn’t load unit structure.
WARNING: Never switch off the unit (for a temporary stop) by switching off the main switch: this component should
be used to disconnect the unit from the power supply only for lengthy stoppages (e.g. seasonal stoppages). Besides,
failing the power supply, the crankcase’s heaters are not supplied thus resulting in a possible breakdown of the
compressors once the unit is switched on.
WARNING: Do not modify the internal wiring of the unit otherwise the warranty will terminate immediately.
WARNING: The summer/winter operating mode have to be selected at the beginning of the related season. Frequent
and sudden changes of this seasonal operating mode have to be avoided in order to prevent severe damages to
compressors.
WARNING: When you first install and start-up the unit make sure that the unit is working properly in both cooling
and heating modes.
7SHUTDOWNS FOR LONG PERIODS
The types of shutdown depends on the weather of the site where the unit is installed and on the period of the stop. The antifreeze
system, if it’s installed, stay on work also with the on-board control unit in “OFF” position.
If the time of stop is long and the temperature is low, we recommend to drain the hydraulic circuits or use a mixture of water and
glycol.
Drain the hydraulic circuits and shutdown the unit with this passage:
Turn off the unit by placing the switch of each unit to "OFF" position.
Close the water valves.
Place the general differential circuit breaker to "OFF" position, if it is installed.
If the temperature drops below 0°C there is serious danger of frost: add a mixture of water and glycol in the
plant, otherwise drain the hydraulic circuits of the plant and of the heat pump.
WARNING: the operation, although it was transient, with water temperatures below +5°C is not guaranteed on
the basis of the limits set out in Paragraph 14.2. Before you turn the unit on after a long off period, make sure
that the temperature of the mixture of water and glycol is higher than or at least equal to + 5°C.
8MAINTENANCE AND PERIODICAL CONTROLS
WARNING: All the operations described in this chapter HAVE TO BE CARRIED OUT BY TRAINED STAFF ONLY.
Before any operation or before entering the inner components of the unit, be sure that the power supply is
disconnected. The compressor’s heads and discharge piping are usually at high temperature levels. Be very
careful when operating in their surroundings. Aluminium coil fins are very sharp and can cause serious wounds.
Be very careful when operating in their surroundings. After maintenance operations, re-install the cover panels,
and fix them by means of screws.
The refrigerant circuits must not be filled with different gas other than that indicated on the nameplate. The use
of a different refrigerant can cause severe damage to the compressor.

HP-OWER
14
It’s forbidden to use oils other than those specified in this manual. The use of a different oil can cause serious
damage to the compressor.
The temperatures of heads and discharge piping of the compressor are usually high.
Be careful when working near condensing coils.
The aluminum fins are very sharp and can cause serious injuries.
After the maintenance operations, close the panels tightly with the fastening screws.
All operation have to be registered on the last page of this manual: without this registration, the guarantee will be not available.
