INTEGRATED STORAGE COLLECTOR SFERASOLTM

USE AND MAINTENANCE MANUAL

SferasolTM.

SFERASOLTM is planned to produce sanitary warm water with the aid of the direct

and diﬀused solar energy. Water temperature supplied by a SFERASOLTM panel

depends on several external factors, varying according to the season, the place

and the time of the day.

Depending on weather conditions, the main parameters inﬂuencing SFERASOLTM

eﬃciency parameters are feed water, solar energy and environmental tempera-

ture.

SFERASOLTM surface heats the thermal liquid by means of the solar energy that

circulates in the two hemispheres. The liquid is then conveyed to the internal

exchanger heating the water contained in the boiler.

Water temperature of mains supply is not constant during the year.

During seasons with few sun exposure and low environmental temperature,

SFERASOLTM ensures pre-heating of water and must be supported by the main

hot water heating system.

As far as heating losses during night hours, these are minimized by the thermal

insulation of the water accumulating tank.

In addition, the spherical shape of SFERASOLTM panel allows an air formation in

the captators which reduces any further thermal losses.

USE AND MAINTENANCE MANUAL

Before starting SferasolTM.

Before starting the machine, staﬀshould read the use and maintenance booklet,

in particular “safety basic instructions”.

Occasional users (especially for maintenance and repairing) should read the pre-

sent user manual before starting operations.

More than reading use and maintenance booklet, it is necessary to follow all stan-

dard rules connected to accident prevention and environment protection, like

safety clothes and accessories.

The use and maintenance booklet has to be stored in an easy to use position for

an easy consulting.

Each machine modiﬁcation must be done only under manufacturer approval.

The present rule shall be applied also with the safety device installation.

Spare parts requirements shall be in accordance with the manufacturer speciﬁ-

cations.

Safety basic instructions.

SFERASOLTM has been manufactured respecting safety rules and in accordance

with Machinery Directives:

2006/42CE

2006/95/CE

2004/108/CE

Final user could be in danger if the machine components are damaged or worn out

or if SFERASOLTM is improperly used.

Use SFERASOLTM exclusively when all the components and safety protections are

perfectly functioning.

Use the machine only in accordance with the present instructions.

Always remember safety rules and risks during the machine working and follow the

rules of the present user and maintenance booklet.

Each defect that should compromise safety should be immediately eliminated.

USE AND MAINTENANCE MANUAL

Transport and storage.

Follow basic rules for operation with cranes and fork lifts, loading charges ma-

chineries, etc.

Each lifting operation must be done with machineries with a suﬃcient loading

power.

Move or lift SFERASOLTM panel with maximum care ensuring lifting systems to

the apposite hook on the top of SFERASOLTM panel and follow the instructions

below.

Check that lifting powers are suitable for the machine weight.

Take care during lifting and be sure that no unbalancing is present.

SFERASOLTM unit net weight with water storage tank SF-S (empty): 130 Kg.

During transport ensure that SFERASOLTM panel is always vertically positioned.

SFERASOLTM panel should be slippering protected during transport to avoid

damages.

If SFERASOLTM panel has already worked, disconnect all connections before mo-

ving the machine.

In case a fork lift or crane are not available, SFERASOLTM panel should be hand-

led considering the weight of the appliance.

Use the special white plastic cover supplied for the appliance storage.

SFERASOLTM can be stored following the same conditions for transport. No par-

ticular care is necessary, but storage place must be clean and the appliance

should be covered in case of a quite long non working period, protecting it from

shocks or tumbles.

N.B.: Do not leave packaging material in the environment.

They must be disposed in accordance to local environmental rules currently in

force.

USE AND MAINTENANCE MANUAL

SferasolTM positioning.

Installation area requirements.

Follow carefully instructions below before connecting and starting SFERASOLTM

panel.

Manufacturer will not be responsible for damages caused by the failure in re-

specting the following requirements

Packing removal.

SFERASOLTM packing must be removed in the installation place to avoid shocks

during transport. Keep the appliance covered until the boiler is ﬁlled with sanitary

water, in order to avoid ﬁlling liquid boiling

Installation place and base.

Choose carefully installation place and base before installation.

Basement on which the machine will be positioned must be planned so that is su-

itable to hold the machine weight. Before machine positioning the area must be

cleaned and planarity must be checked by a level device. Each diﬀerence from

optimal condition should be modiﬁed by the use of thickness sheets.

Connections.

Customer shall agree with the Installation Service all necessary plumbing and electri-

cal connections to ensure correct installation in accordance with Electrical and Plum-

bing Regulations currently in force.

Grounding.

SFERASOLTM must be connected to the general ground network.

Orienting and shading.

Correct installation is fundamental for maximum eﬃciency of the solar system.

During installation follow the indications below in order to ensure maximum eﬃciency

of the solar system.

INTEGRATED STORAGE COLLECTOR SFERASOLTM

USE AND MAINTENANCE MANUAL

• SFERASOLTM must be installed in a place with total daytime sunlight. If not possible,

sunlight should be at least from 11 a.m. to sunset.

• When installed, SFERASOLTM inspection door must be always SOUTH-side oriented

• In order to avoid temperature losses due to piping length, SFERASOLTM panel should

be positioned next to the Storage tank and/or to the collection point.

• After installation, ensure that SFERASOLTM is protected against wind which reduces

the greenhouse eﬀect obtained by the spherical shape of the system.

• Any changes to the optimal orientation would reduce SFERASOLTM eﬃciency, with no

responsibility of SFERASOLTM panel.

• In case optimal installation is not possible, the number of SFERASOLTM panels requi-

red would increase to compensate eﬃciency losses.

• Shading (due to trees, buildings or any other obstacles) should be avoided in order to

ensure at least 4-6 hours of complete sunshine exposure during maximum sun thermal

radiation.

• Basement on which the machine will be positioned must be planned so that is sui-

table to hold the machine weight

• A well corresponding to the appliance base should be advisable and lay underground

a piping connection for water and electrical connection (min. diam. 100 mm.).

• Fix SFERASOLTM to the support foot through 4 wedges diam. 8 mm in the apposite

holes on the base, ensuring that 3 mm. washers are ﬁtted with the wedges.

This operation avoids any condensate stagnancy inside the support foot.

To this purpose, do not seal the support foot to the base with mortar or silicon.

SFERASOLTM eﬃciency can be further improved by following previous suggestions,

thanks to its innovative shape, exploiting also the shaded part of the appliance.

Exploiting diﬀused energy, it is advisable to use light colors for any walls next to

the appliance, and to create a 1,5 diam.white gravel circle in case of installation

on lawn.

The above advices enable a reﬂection phenomenon of sunlight which optimizes

the appliance eﬃciency.
