Preface Overview

PREFACE

ECO-SPARK®SOLAR POOL PANELS ARE MANUFACTURED UTILIZING STATE-OF-THE-ART TECHNOLOGY

AND PRODUCTION TECHNIQUES. ECO-SPARK®COLLECTORS ARE SLEEK AND SIMPLE, YET THE PATENTED

OVERMOLDING DESIGN MAKES THEM DURABLE ENOUGH TO LAST A LIFETIME. CORRECT INSTALLATION

IS ESSENTIAL TO THE OVERALL SUCCESS OF THE SYSTEM. INSTALLED CORRECTLY, AN ECO-SPARK®

SYSTEM IS PRACTICALLY MAINTENANCE FREE, AS IT TAPS SOLAR HEAT YEAR AFTER YEAR.

This manual contains easy, step-by-step instructions to help ensure that your installation meets our

recommended standards. It also includes techniques and tips gathered from experienced contractors, to

save you time and effort. An installation NOT conducted by an authorized dealer and according to the

instructions detailed in this manual may void warranty!

OVERVIEW

eco-Spark®solar heating systems can be either mounted on a roof or on the ground with a blanket

underneath. If a change of angle is necessary a special rack must be constructed.

Before installing the collector, please take the time to read the following instructions to ensure smooth and

successful installation and operation.

Make sure you follow the safety and operation guidelines when installing Magen's eco-Spark® solar

collector.

The general performance and energy savings that you can expect from your solar system will depend upon

several factors: insolation, ambient temperatures, wind and the facility's characteristics.

SAFETY PRECAUTIONS AND REGULATIONS

Magen's solar collectors must be installed by an authorized installer. The installation work must conform

to local authority’s standards and regulations. Consult the appropriate authorities or check with your

local building department concerning local permits and requirements before you begin the job.

Electrical installation must be performed by an individual qualified in electrical installations, and conform

to local regulations.

Warning! Always check that power is turned off before attempting any wiring or electrical hookups,

especially when water is present.

Always exercise extreme caution, care and good judgment when working on or around a roof. Avoid

hazards such as overhead electrical wires or loose shingles/roof tiles. Secure ladders so they will not slip

or fall. Wear shoes with proper tread to prevent slipping on a ladder or slopped roof areas.

Always use approved lifting devices when installing solar systems at heights. All occupational health and

safety issues must be adhered to.

Important: While this manual explains how to install eco-Spark®solar panels properly in typical

situations; it cannot address all the possible individual cases. If you have any installation questions,

contact your sales representative for assistance. As the installing contractor, you are responsible for

fulfilling top quality standards when installing eco-Spark®panels.

Preface Safety precautions and regulations

Important: Avoid walking over the eco-Spark®collectors! Wherever possible, the system should be

installed so that all parts of it are accessible.

Warning! Water in the collector can reach high temperatures (up to 90°C, 194°F)! Take caution while

handling the collector to avoid burns.

Transport and handling

eco-SPARK® solar collectors must be secured during transportation to avoid damage to the packaging,

and scratches to the collector’s cover. Keep the marked side of the package up and consider it fragile.

Keep original package for storage in warehouse and for transporting solar panels prior to the installation.

While in storage or when transported, up to 8 boxes can be stacked on top of one another.

Lightning protection

An authorized lightning protection specialist should be consulted to examine the required lightning

protection measures required. eco-Spark®solar system is made from "all plastic" materials.

Preface Definitions of terms used in this document

DEFINITIONS OF TERMS USED IN THIS DOCUMENT

Module –39 individual tubes connected to 30 cm (1') wide manifold on both ends. Each module is encased

in transparent multi-layer polycarbonate plate.

Panel –Four (4) modules welded to one another at the manufacturing facility. The collector absorbs the sun

rays and transforms them into thermal energy.

PC Glazing –Durable Polycarbonate glazing with a UV blocking layer.

Differential Controller –An electrical device that operates the solar pump, according to a pre-set

temperature difference between the collector temperature and the pool temperature.

Solar Pump –A pump that runs water to/from the collectors and the pool's filtration circuit. Operates

according to the differential controller.

Vacuum/Air Relief Valve –A valve connected to the upper point of the solar system to release trapped air

when the system turns ON, or to allow air into the system when it turns OFF.

MODULES/PANELS/BANKS

eco-Spark® collectors are manufactured as individual "modules", and connected together in the factory in

groups of four modules to form "panels". You connect the supplied panels together to form "banks" of

various lengths, depending on the individual requirements at your site.

An eco-Spark®solar pool heating system consists of one or more banks of collectors, connected to the

swimming pool filtration system.

Module –Modules

come in two lengths,

always 30 cm (1') wide.

Panel –4 Modules

welded to one another

in the factory.

DESIGNING YOUR SYSTEM THE SOLAR SYSTEM LAYOUT

DESIGNING YOUR SYSTEM

This chapter describes the factors you need to take into account when designing your system, and the

process planning of the systems' structure.

During all stages of the design and construction keep in mind that you want to produce a system for the

customer that will be as efficient and as AESTHETICALLY PLEASING as possible.

THE SOLAR SYSTEM LAYOUT

The first thing to do is determine the location of your solar heating system. The following factors must be

taken into account.

COLLECTOR AREA

The total panel area must be large enough to heat the pool efficiently. In addition to the pool's surface area,

the exact optimum size depends on many factors such as: solar radiation intensity, climate, latitude, roof

orientation, slope, winds, pool cover (at night), pool volume and shading.

An approximate “rule of thumb” is to allow for a collector area equal to 60% of the pool's surface.

PROXIMITY TO POOL

The panels need to be as close to the pool as possible to reduce heat loss in the plumbing and

eliminate the need for an additional pump.

LOCATION & ORIENTATION

Ideally the collectors should be mounted on a flat or tilted roof or on an elevated ground mounted rack,

facing south (in the North Hemisphere). Where necessary, East facing or west facing roofs can be used (in

that order of preference). If you have to mount collectors on a north facing slope, it is recommended to

construct a reverse rack.

Tip: For ideal self-cleaning of the glazing it is recommended to install the collector at a minimum angle

of 150.

How to locate the collector on the selected roof? The lower side of the collector is the side where the

Stoppers are connected. Stopper (Cat Num. 1233160) is attached to the edges of every single module (8 in

total) and mounted to the unglazed tubes. The stoppers eliminate the possibility of the glazing moving due

to thermal expansion/contraction and contribute to the collectors' strength and stability.

IMPORTANT: A collector should be installed so the stoppers are located on the lower part of the

collector. A system that will be installed differently will function less efficiently.

DESIGNING YOUR SYSTEM Tilt

TILT

Be sure the planned position of the collector panels allows for them to drain naturally when the pool pump

shuts off.

Tip:

The “ideal” angle for maximum solar collection should be similar to the local latitude or up to 15

higher. However, any angle that allows for self-drainage of the panels is sufficient.

Important: Mounting the solar panels in certain locations, and/or constructing a support structure (if

necessary) may require a building permit. Consult with the appropriate authorities, or check with

your local building department, about permit requirements and codes that may apply, before you

begin work.

PREPARING A SCHEMATIC DIAGRAM

Once you have decided on the location for the panels, prepare a schematic diagram of the

system you wish to construct, taking into account the collectors sizes available.

1. Fill in the "Site evaluation sheet” at the end of this document. This will help you decide on

the best system for your site.

2. Prepare a schematic drawing of the installation area. Include the proposed location of the

feed and return lines.

3. Use the panel dimensions on page 8, to sketch the system you will construct.

Important: Large scale or commercials systems must be designed by a professional engineer.

Tip: Roof areas often give the impression of being bigger than they really are, so be sure to actually

MEASURE the available area before making your drawing.

Note: Where possible construct your system using panels of the same length (if possible the largest

length). In cases where space limitations do not allow for a complete panel, individual modules can

be ordered. Modules can then be connected to one another or to panels in exactly the same manner

that panels are connected to each other. Use individual MODULES only if essential.
