4.7 Lifting and handling
When unloading the unit, it is strongly recommended that sudden movements are avoided in order to protect the refrigerant circuit, copper
tubes or any other unit component. Units can be lifted by using a forklift or, alternatively, using belts. Take care that the method of lifting does
not damage the side panels or the cover. It is important to keep the unit horizontal at all time to avoid damage to the internal components.
The Source heat exchangers fins are sharp. Use protection gloves.
4.8 Location and minimum technical clearances
All units are designed for external installation : any overhang above the unit and location near trees, if they partially cover the unit,must
be avoided in order to prevent air by-pass. It is advisable to create a proper mounting plinth, with a size similar to the unit foot-print. Unit
vibration level is very low: it is advisable however, to install vibration dampers (spring or rubber) between the plinth and the unit base-frame
to keep vibrations at a very low level. It is vital to ensure adequate air volume to the source fan. Re-circulation of discharge air must 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:
The unit has to be installed such that maintenance and repair is possible. The warranty does not cover costs for the
provision of lifting apparatus, platforms or other lifting systems required to perform repairs during warranty period.
The installation site should be chosen in accordance with EN 378-1 and 378-3 standards. When choosing the
installation site, all risks caused by accidental refrigerant leakage should be taken into consideration.
All air to water heat pumps, during defrost mode, produce condensate at the base of the source heat exchanger. If
the ambient temperature is below 0°C the water may freeze, creating a thick layer of ice within the unit. This layer
of ice, in specific conditions, may damage the heat exchanger and therefore, to guarantee correct operation of the
units it is highly recommended to raise the unit of a minimum amount (F). This recommendation becomes more
important if the unit is to be installed in a location that is subject to heavy snowfall.
