NOBEL, Xilinakis D. & Co Industry is active in the Solar Energy Field since 1975, always with high-tech equipment,

ultra-modern facilities and certied products of high quality. Our experience and know-how support our co operations, before and after sales, both in Greece and abroad.

In the present manual you will nd all necessary instructions with regard to the installation, operation and maintenance of NOBEL Solar Water Heaters.

Nowadays, the necessity for production and saving of energy without at the same time polluting the environment has become common knowledge. The planet’s conventional energy resources are diminishing to a

threatening level as our society’s energy requirements are increasing, generating pollutants that affect the climate’s

balance.

Renewable energy sources promise a solution to the energy problem as well as to pollution. Gradually, the international legislation is changing and encouraging - or even imposing - the use of alternative energy products, with the aim to satisfy energy requirements without endangering the environment.

DOMESTIC HOT WATER CONSUMPTION

Statistically, it is estimated that the mean family consumption is 35 to 50 litres daily per person. If we add the consumption of a washing machine and a dishwasher, when these are connected to the solar water storage tank, then each requires 20 litres per day (per wash).

Thus, a family of four, for example, with a mean hot water consumption of 40 litres per person, needs an 160 litres solar water heater. If household appliances connected to the solar water heater are added, then the demand increases by at least 40 litres daily. In order to take full advantage of the solar water heater, maximum use of hot water should be made during daytime, so that the system can continuously produce hot water during the daylight hours, maintaining thus its maximum efciency.

SOLAR WATER HEATER OPERATION - WATER HEATING

The collecting surface absorbs solar energy and heats the liquid (water or antifreeze mixture) that circulates in the water element. This liquid when heated becomes lighter and is directed to the water storage tank where it heats the water. The ow of the collector’s liquid is accomplished naturally and not forced (thermosiphonic ow). The factors that affect the temperature of the water supplied by a solar system are many and their values vary according to the season, the time of day and the location. Keeping in mind that the solar system is a system that is exposed to the weather conditions, basic parameters affecting its performance are the mains water temperature, the available solar energy and the ambient temperature. The mains water does not have a constant temperature throughout the year, being much colder in winter compared to summer. Considering 45°C as a satisfactory temperature for the domestic hot water (in order to full the needs of a home) and based on statistic values, in winter the temperature of the mains water has to be increased by approximately 35°C, whereas during the summer the increase is 20°C. Similarly, the available solar energy does not remain the same throughout the year, being much less in the winter months than in the summer months. During periods of reduced sunlight and low ambient temperatures, the solar water storage tank assures the preheating of the water and is assisted by an electrical heating element or the central heating water storage tank (triple action solar water storage tanks). As far as night-time temperature losses are concerned, these are limited as much as possible by the solar system’s powerful thermal insulation. They are nevertheless affected by ambient temperatures, which vary depending on the location and the weather.

SOLAR WATER HEATERS

RELIABILITY - HARMONY - AESTHETICS

NOBEL Solar Systems constitute an ecological

proposal and an effective energy solution, combining high output, autonomy, aesthetics, facility in the installation and money saving. They are made of excellent materials according to international specications and have all the certications and tests that conrm their quality.

They are highly aesthetic systems, which can be simply and quickly installed to blend with the traditional or modern architecture of a building and to provide free hot water almost the whole year round. Even in regions with low sunlight they achieve the preheating of the water, which contributes to a drastically reduced consumption of conventional energy.

With the use of solar systems, thermosiphonic or forced circulation, is achieved energy saving of 70-100%. At the same time the operation time of the water tank or electric resistance is decreased, depending on the sunlight of each region and the system’s size, with simultaneous reduction of emission of carbon dioxide.

LABELING

NOBEL solar water heaters are identied by two labels, one of them on the tank and the other on the collector. On these one can nd all the details of the system. The information provided is important for the future identication of

the system.

GENERAL INSTALLATION RULES

ATTENTION: Installation must be in compliance with local & national rules concerning water and electrical

installations (plumbing, electricity, hygiene, urban and others).

The solar system’s packaging must be removed at the site of installation in order to protect the device from shocks during its transportation, making sure that the collectors are not supported on their pipe joints. Until installation is completed, the collector’s glass must remain covered until the water storage tank is lled with domestic water, so as to avoid the boiling of the lling liquid or the breaking of the glass. The plastic protective caps must be removed from the water storage tank’s and the collectors’ pipe joints.

Installation location - shading: Prior to installation, a proper selection of the location must be made by the installer (in agreement with the customer), and the surface must be checked (taking into consideration its static resistance), so that it can bear the weight of the system. On inclined roofs the system should not be placed between two beams but above a single one. The position chosen for the solar water heater installation should not be shaded by any obstacles such as trees, buildings and other all year round, so as to ensure at least 4 hours of uninhibited exposure of the collector to the sun during the midday hours.

Any deviation means a reduction in the system’s performance. If a deviation from the proper orientation cannot be avoided, then the system’s performance should be corrected by increasing the collector surface, following a study and evaluation of the specic conditions that apply. As the sun ray’s angle of attack varies with time but also depending on the system’s location, the collector’s angle should be approximately equal to the installation location’s latitude. At this angle the maximum energy gain on an annual basis is achieved.

Installation particularities: In case there is no compatibility between the surface where the solar water heater will be installed (inclined or at) and the standard equipment provided with the system, a different kind of equipment should be used. The responsibility for the equipment chosen lies on the installer and in no case on the company. It is up to the installer to propose & install the different equipment required, who must previously agree it with the customer.

Special weather conditions: In regions suffering from heavy snowfalls, please make sure that the snow is always timely removed. For this case and cases of regions with storms, high wind velocity, rainfall, cyclones, tornadoes, the system must be placed on the roof as rmly as possible and must be tightened with extra metal stripes. In areas where these conditions occur and hail of more than 20mm in diameter is to be observed, it is recommended that insurance for the solar water heater is issued. In every case, it is recommended to secure your solar water heater on the support base system with more metal belts than those provided.

Orientation - optimum angle: a basic factor for the system’s optimum performance is the selection of its angle and orientation for its particular location and the time during which the maximum gain is required. The solar system should be positioned so that the collector’s surface faces the geographical south, if the installation takes place in the Northern Hemisphere (and the geographical north for the Southern Hemisphere), i.e. it should always face the Equator.

CLASSIC

Nobel Xilinakis D. & Co preserves the right to change all specications of the products and their accessories without prior notice

Piping: the routing of the piping and cabling must be agreed upon between the installer and the client, so as to ensure the proper installation of the solar system in compliance with local rules concerning water and electrical installations. Make sure that the tubes connecting the storage tank with the collector and the piping to/from the water heater are insulated in such a way that they can withstand temperatures covering the range of: -30°C to 120°C. Anti-UV protection must be used for the insulation.

Antifreeze Liquid: The special heat transfer medium used in the closed circuit protects the system from freezing and from salt accumulation inside the collector tubes. The jacket in which the heat transfer medium’s circulation takes place, does not communicate with the water tank. The thermal uid must be well mixed with water in a percentage that is necessary to protect the system. The responsibility for the appropriate heat transfer medium quantity as well as for the use of other liquid than the one accompanying the solar water heater lies on the installer and in no case

on the company.

The use of water or inappropriate liquid may annul the warranty validity. After the installation is completed, the area where the work was executed should be clean & tidy. The warranty should be lled in and the customer should sign it and immediately mail it to the company. The customer should ll in the check list provided by the company. The company does not hold any responsibility that may be the result of an inappropriate installation or incorrect use of components used for the solar water heater installation.

INSTALLATION POSITION

The installation is only allowed on roofs and at surfaces of adequate bearing capacity. Before you proceed with the installation, make sure that the roof and/or the construction is of adequate bearing capacity in terms of statics, always according to the expected maximum loads at the installation point. If the installation is in a place with an extremely big wind and snow load, the system as a whole should be statically checked by a skilled person, e.g a specialized engineer. In special cases, strengthening or more solid constructions may be required.

Space requirements for installation on the roof

TILED ROOF

For the installation on the roof the following points must be taken care of:

y The minimum distances from the ends of the roof should be:

- From the sides: distance equal to the width of two tiles

- From the top of the roof: distance equal to three rows of tiles

y The minimum distance limit of 0.8m should necessarily be respected, in order for the collectors and the mounting

accessories not to be exposed to winds the power of which increases on the perimetrical edges of the roof.

y Have protection glasses on, as well as appropriate work uniform, protection shoes, protection helmet and special

long hair net.

y Do not wear baggy clothes or jewelry, as they me be trapped in movable parts. y If, despite the use of protection glasses, antifreeze liquid comes in contact with your eyes, wash off your eyes with

plenty of water and with the eyes wide open.

y Please wear protection helmet during the installation works executed at the level of or above the head.

Installation of the water storage tank

y For the transportation, mounting & installation of the tank use forklifts suitable for the dimension and weight of the tank.

y Please protect the enameling surface from beatings during transportation and installation. y Due to the tank’s weight, there is a risk of accidents. Please make sure that the bearing capacity of the ground

where the tank is going to be installed is adequate, when the tank is full.

cold water pipe is then connected to the ball valve with an insulated plastic pipe Ø15.

2. The “HOT WATER OUTLET” is then connected to the hot water pipe of the consumer network through an

insulated plastic pipe (Plastic pipes are recommended to minimize electro-corrosion).

3. Filling the water storage tank WITH WATER: With the ball valve and a hot water tap open, the water storage tank

is allowed to be lled with cold water. When water starts to run out of the tap, the water storage tank is full and the hot water tap can be closed.

CLOSED LOOP FILLING

ATTENTION! Before starting to ll the closed loop with anti freeze liquid, the water storage tank has to be completely

lled with water.

ANTI FREEZE LIQUID is an advanced, propylene glycol based special product, designed and formulated in order to ensure effective heat transfer properties at high or low temperatures. It is non-toxic and provides protection up to -37°C (solution 55% v/v with water). It is especially designed to provide excellent anticorrosion properties.

ATTENTION!

y Any intervention - work on the solar water heater must be carried out only by specialized technicians and where

electrical components are concerned, only by qualied and licensed electricians.

y All solar water heater service data must be entered on the respective chart on the warranty document (term of

warranty).

y In areas where extreme weather conditions are common (hail storms, storms, tornadoes, etc.) it is recommended

that the appliance is insured.

POST INSTALLATION INSTRUCTIONS

Before using the system make a nal check. Open all the valves and check for any kind of leakage. Repeat the inspection after 30 minutes. Check if the system is lled with water and antifreeze uid according to the company’s instructions. In case of any failure condition a specialized technician should be called in.

Following its installation, the solar water storage tank needs about 2 days in order to achieve its maximum efciency.

For this reason it is recommended that there is no hot water consumption during the rst two days following installation, even if there is ample sunshine.

A basic periodic maintenance will assure the long life and high efciency of the solar water heater.

y It is recommended that the appliance is inspected in situ according to the instructions stated in the guarantee

twice a year and checked for possible damage (breaking) of the collectors’ glass, leaks in the connecting piping to the mains and to the consumption system, inspection of the pipe insulation and cleaning of the glass.

y If the collectors’ glass is broken, it should be replaced immediately.

y It is recommended that the glass is washed at an hour of low sunlight to avoid damages due to expansion-

contraction, due to temperature changes.

y If the ttings are worn (screws, pugs, piping, etc), these should be replaced at the owner’s cost.

y The level of antifreeze in the closed circuit must be checked annually (as it could need toping up), to ensure the

efcient operation.

y In cases where there is to be no use of hot water for long periods of time (e.g. during the summer holidays), it

is recommended that the collector surface is covered with an opaque cover in order to avoid the building up of high temperatures, which could trip the thermoelectric fuse of the thermostat and cut the electrical circuit. (See paragraph “RESETTING THE THERMOELECTRIC FUSE F”).

y During the build-up of high pressure in the thermal tank, it is possible that the safety valve will open and water will

run out. This is a normal function that protects the water storage tank from high pressures. If the mains pressure exceeds 4 atm., it is necessary to add a pressure reducer - expansion tank.

y Do not switch on the electrical heating element in the following cases:

Α) When the mains water supply has been cut

Β) When the connecting pipes have frozen and there is no water ow from the water storage tank to the taps.

Caution! Place taps with thermostatic regulation up to 38°C for hot water use to prevent burns which may be caused

by the high temperature water in the solar water heater.
