Before the installation and use of a SOLATHERM Solar Water Heating System please read and

observe carefully all the instructions concerning the installation, maintenance and use of the

systems, in this manual. The non-observance of these instructions may result in the

cancelation of the warranty.

GENERAL SAFETY INSTRUCTIONS

•All installations and maintenance must be performed by qualified and certified professionals,

following all relevant local norms and regulations (1), industry codes, and according to the

manufacturer’s instructions.

•Always make sure that the installation site, especially on pitched roofs and roof tops, is adapted

to the weight and mechanical restraints of the system, as well as any further weight expected

(snow, rain, etc...). SOLATHERM declines any responsibility that may arise from an improper

or defective installation or from incorrect manipulation of the system or accessories composing

it.

•For a safer installation on roofs, it is recommended that the system be installed in such a way

that the tank be placed over a slat or batten, rather than between them.

•Always make sure there is enough space around the solar system for maintenance purposes, as

well as for the electric cabling and plumbing. It is recommended to agree with the client for the

location of the installation and the routing of pipes and cabling.

•In regions with heavy snow fall or strong winds, it may be necessary to further anchor the system

to the point of installation. In this case it is up to the installer along with the client to determine

the best and safe way to install the system. Additional fixing points or equipment may be

required.

•Avoid installations under direct solar radiation conditions due to the very high performance of

the solar panels and risks of severe burning or thermal shocks to the system. In the case of

installation under these conditions, it is very important to make sure the solar panels are well

covered and shaded from the sun.

•Never fill the closed circuit or connect the electric element with an empty tank. The tank must

always be filled with water during these operations due to a risk of severe damage to the system.

•Before starting the installation or maintenance, the main power supply to the system must

always be turned OFF.

•The use of plastic, PVC or polypropylene piping is not recommended for Solar Water Heaters due

to the very high temperatures developed by the systems. In any case, make sure that all the

piping used in contact or close to the systems outlets can withstand minimum temperatures of

90ºC, or 180ºC if in contact with the primary circuit.

SOLATHERM recommends the use of copper or stainless steel piping for safer and higher

performance.

•Following the first two years from installation, annual maintenance is recommended. Please

refer to the “Maintenance and Servicing of the Solar Water Heating System” section of this

manual.

•A mixing valve is compulsory on the hot water outlet in order to limit risks of burning and a

pressure reducing valve is highly recommended on the cold water inlet.

SOLATHERM reserves the right to modify characteristics of the products or their accessories and components without prior notice.

GENERAL INSTALLATION INSTRUCTIONS

•Always make sure that the location chosen for the installation of the solar water heater is not

shaded by any obstacles (walls or other structures, trees and vegetation, other buildings, etc…)

at any moment. It is recommended to ensure at least 4 hours of direct sunlight around mid-day

during the winter solstice. In case of obstacles please observe minimum distance of the

collector(s) from the obstacle, as per the following calculation:

d=h x κ

where: κ=1/ tg(61°-φ) and φ= latitude of installation point.

The table below represents the (κ) coefficients for some latitudes:

LATITUDE 36° 37° 38° 39° 40° 41° 42° 43° 44° 45° 46°

κ (m) 2,144 2,246 2,355 2,475 2,605 2,747 2,904 3,077 3,270 3,487 3,732

In order to calculate the minimum distance (d) of the system from the obstacle one must multiply the

height (h) of the obstacle by the appropriate (κ) coefficient.

For latitudes, other than the ones reported in the table above, the formula must be used in order to

calculate the (κ) coefficient.

•The collectors must face towards the South when installed North of the equator and towards

the North when installed South of the equator. A deviation of up to 30º East or West is tolerated

with a minimum effect on the performance of the system.

Note: a deviation towards the East will result in a greater output of the system until mid-day, while

a deviation towards the West will result in a greater performance of the system in the afternoon.

•The optimal inclination depends on latitude of the installation point. In order to avoid fastidious

calculations, it is recommended as follows:

oIf the system is used mainly during summer months: β=φ - (10 to 15)

othe system is used mainly during winter months: β=φ + (10 to 15)

othe system is used all year round: β=φ

Where βis the collector inclination and φthe latitude of the installation point.

•If the Solar System is installed in a location with a pitch lower than 13º or greater than 45º, additional

or different equipment may be necessary.

•Always make sure that all the piping of the primary and secondary circuits, going to and coming from

the Solar Water Heater, are very well insulated, even in hot climate regions and treated for UV

radiation.

SOLATHERM reserves the right to modify characteristics of the products or their accessories and components without prior notice.

•Always use counter force (opposite force) when installing the tightening fittings (especially olive

fittings) to avoid internal cracking and breaking of copper welds between tubes. Breaking of the

welds due to non-observance of this point is excluded from warranty and will result in cancelation

of the warranty.

•For closed circuit systems, always prepare and mix thoroughly the thermal fluid mixture in a bucket

before filling the system. Never fill the system with thermal fluid and water separately.

•Avoid leaving the Solar System for long periods without using hot water (holidays, prolonged

absences, etc...) due to risks of overheating, or make sure the solar panels are covered during this

period.

WARNING:

IF THE HOT WATER SYSTEM IS NOT USED FOR TWO WEEKS OR MORE, A QUANTITY OF HIGHLY

FLAMMABLE HYDROGEN GAS MAY BE ACCUMULATED IN THE WATER HEATER. TO DISSIPATE THIS GAS

SAFELY, IT IS RECOMMENDED THAT A HOT TAP BE TURNED ON FOR SEVERAL MINUTES UNTIL DISCHARGE

OF GAS CEASES. USE A SINK, BASIN, OR BATH OUTLET, BUT NOT A DISHWASHER, CLOTHES WASHER OR

OTHER APPLIANCE. DURING THE PROCEDURE THERE MUST BE NO SMOKING, OPEN FLAME OR ANY

ELECTRICAL APPLIANCE OPERATING NEARBY. IF HYDROGEN IS DISCHARGED THROUGH THE TAP, IT WILL

PROBABLY MAKE AN UNUSUAL SOUND AS WITH AIR ESCAPING.

•The safety of the system and validity of the warranty are conditioned by the use of genuine

SOLATHERM spare parts and accessories. Please only use genuine SOLATHERM spare parts and

accessories from your nearest SOLATHERM dealer or contact the manufacturer.

SOLATHERM declines any responsibility that may arise from the non-observance of the installation,

maintenance and use instructions herein, non-observance of relevant local norms, regulations and

industry codes, improper or defective installation, or incorrect manipulation of the system or the

accessories composing it.

A solar water heater (SWH) is a system that can provide hot water, using the direct and indirect

solar irradiation. It consists from a storage tank where the sanitary water is stored (secondary

loop) and the solar panel(s) (solar collectors) which, along with the annular heat exchanger of

the storage tank (jacket) and the connection pipes connecting them, constitute the primary

circuit.

Heating of the water in based on a natural principle of hot being lighter and less dense than

cold, therefor by stratification, is always at the highest point while cold always sinks below. This

is why these types of solar systems are referred to as Natural Circulation or Thermosiphon

Systems.

In a Solar Water Heater, the thermal fluid (in the primary circuit) is heated by the sun in the

solar panels, getting lighter, so tends to rise up the solar panels, through the connecting pipes

and inside the heat exchanger, where it transfers the heat (calories) to the sanitary water stored

in the storage tank. While it exchanges heat with the sanitary water, the thermal fluids

temperature is lowered, slowly returning back to normal and regaining weight, thus returns by

gravity back to the solar panels to start the heating cycle all over again.
