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. Be sure also, using suitable obstructions,
that can avoid accidental power supply switching ON until the end of all operations.
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,
b
eing 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 ONE 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 absolutely
necessary to respect the following clearances:

CAUTION:It is obligatory to install the unit on a firm and appropriate basement to support its weight. Considering
the weight of the unit, possible vibrations and resultant noise, we do not recommend suspension installion of the
unit; in this case, the firm is not responsible for any damage or inconvenience that may result.
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 and a dirt separator (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) and a dirt separator. the warranty will no longer be valid If the water flow switch was manipulated or
altered or if the metallic filter and/or dirt separator were not installed. The filter and the dirt separator have to be
kept clean, therefore make sure that are clean after the unit installing the unit, and then check them periodically.
All units are standard supplied with the water flow switch (factory installed). The warranty will be invalidated if the
water flow switch was altered, removed, or if the water filter and the dirt separator were not installed on the unit.
Please refer to the wiring diagram for the water flow switch electric connections.
Make sur that the heating system and the safety valves must comply with the requirements of EN 12828.
5.4.1 Characteristics of Water of the plant circuit

5.4.2 Drainage connection
All the units of series 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 (at the heat exchanger side), with a hole that can allow to drain any
condensed water can leach from plumbing pipes. As the pipes must be well-insulated, the production of condensed water is
however very low and therefore the connection of a drainage pipe to that hole is not very required.
5.4.3 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. Make sure that an extractable
cartridge filter and a dirt separator have been installed.
WARNING: It is required to proceed by air purging periodically in order to eliminate the accumulated air in the
plant circuit system.
WARNING: Make sure to install an automatic air vent valve at the highest point of the system.
5.4.4 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
Drainage pipe fitting

ATTENTION. The air vent is a manual valve. Periodically it is necessary to perform
the air purge operations that accumulate in the system as just described.
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 or (inner diameter size - check the faucet model that is
installed on your own unit
) 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.

9.1 CLEANING OF THE FINNED BATTERY
To perform a proper cleaning, follow the below instructions:
a) Removal of the surface dirts. Deposits like leaves, fibers, etc. must be removed using a vacuum cleaner (use a brush or other
soft tool, carefully avoiding rubbing with metal or abrasive parts). If you decide to use compressed air, it is necessary to pay
attention to keep the air flow always perpendicular to the surface of the heat exchanger for not to bend the aluminum fins. Be
careful not to bend the fins with the nozzle of the compressed air lance.
b) Rinse. Wash with water. It is possible to use chemical substances (specific detergents for finned batteries). Rinse by running the
water inside each single passage of the fins, until they are perfectly cleaned. Be careful to direct the water jet perpendicular to the
surface of the heat exchanger for not to bend the aluminum fins. Avoid hitting the battery with the water hose. It is recommended
to place your thumb on the end of the rubber pipe to obtain the pressure of the desired water jet instead of using special nozzles
that could hit the heat exchanger and damage it.
WARNING: Do not use high-pressure cleaners to clean the heat exchangerin order to prevent excessive pressure from causing
irreparable damage. Damages caused by cleaning using unproper chemicals substances or too high water pressures are not
recommended and will not be recognized.
WARNING: The aluminum fins are thin and sharp. Be very careful to use appropriate PPE to avoid cuts and abrasions. Properly
protect the eye
s and face to avoid splashing of water and dirt during sufflage. Wear waterproof shoes or boots and clothing that
covers all parts of the body.
For the units that are installed in an aggressive atmosphere with a high level of fouling, the cleaning of the heat exchanger must
be part of the routine maintenance program. On this type of installation, all the dust and deposited particulates on the heat
exchanger must be removed as soon as possible by periodic cleaning, following the procedures described above.
9.2 EXTRAORDINARY MAINTENANCE
All extraordinary maintenance work must be carried out by an authorized service center.
9.3 ENVIRONMENTAL PROTECTION
