This installation manual is made for all parties in-volved in installing Parans’ solar lighting system. It deals with planning and installing the Parans system. Parans recommends that this installation manual be studied carefully before the installation and that the installation be performed by professionals.

The Parans system is a lighting solution fromParans Solar Lighting AB (publ), transporting sunlight into buildings.

Ths Parans system consists of Parans solar receivers that collect sunlight, Parans optical fibre cables that transport sunlight through the property, and Parans luminaires that project the sunlight inside the building.

Parans SP3 is the third generation of the Parans system. It contains optics, mechanics and electron-ics, enclosed in a tubular body made of anodized aluminium, glass and ABS plastic. It is a weather resistantant and autonomous unit that tracks the sun with very little site-specific programming.

Parans SP3 features 36 lenses that each focus into an optical fibre. The fibres are bundled into six optical fibre cables. An electrical cable follows the optical fibre cables and is connected indoors.

Parans SP3 uses the direct sunlight, whose rays are practically parallel and can be focused using lenses. The SP3 has a set of 36 lenses, each focusing the light into the end of a plastic optical fibre. The fibres are bundled in cables and can be 5, 10, 15 or 20 meters long. These are the cables that transport the light.

The light that comes through the system is true sunlight, and has a cold white tone. We usually do not notice, but sunlight is actually much colder white than most of the artificial light sources we use. This is one of the reasons why sunlight is so good for us. Our body recognizes sunlight and produces hor-mones to keep us awake during the day.

Sunlight is also the highest possible light quality in that it contains all the colours of the visible spec-trum. This means that we can see more colours and nuances. It is also completely free from flicker - something that no normal electrical light source can provide, since our electrical grid alternates and creates pulses of electricity.

Optical fibres have the amazing property of trapping light, so that it bounces and travels with very small losses through the material. Exactly this trapping of light, is what makes it possible to bend the fibres - light stays inside anyway. Only at the very end of the fibre, the light is released, and can be used for illuminating our indoor spaces.

On very cloudy days, there is no direct sunlight and the SP3 cannot concentrate light. Then the luminaires go dark, and only a small point of light is visible in the fibre end. The system still keeps to the sun path, in order to be ready as soon as the sun becomes visible again. When it does, the light flows through the system and we instantly get access to pure sunlight in our indoor environments. This is how Parans’ solar lighting system establishes a direct contact with the nature outside of our offices, schools, homes, hospitals and other buildings.

InStallatIon PlannIng

An installation plan should include a time sched-ule, qualification and certification requirements for installation workers and building materials, as well as details about the following:

· Luminaire placement · Placement of the Parans SP3 · Ducting of optical and electrical cables · Size and placement of roof and wall penetrations · Place and mode of electrical connection

The Parans SP3 requires direct sunlight. Exam-ine the sunlight exposure throughout the year to avoid placing the solar receiver in a spot that is shaded during seasons when the sun is low.

The Parans SP3 should always be installed facing South or as close to South facing as possible.It is never to be installed more than +/-90 degrees from South.

This applies also to installations in the Southern hemisphere. When powered up, the unit will auto-matically turn to find the sun.

From the Parans receiver to the luminaires, the optical fibre cables can be 5, 10, 15 or 20 meters. Shorter cables are preferred, since attenuation in the optical fibers lowers the light output over the distance. The cables are permanently attached to the receiver and cannot be exchanged in the field.

Penetration of the roof or outer wall should be planned carefully. Note that installation is easier if the penetration is placed outside the striped area marked in the illustration on the opposite page.We recommend the use of conduit for cable duct-ing.

The lighting design should include considerations to how Parans solar lighting differs from artificial lighting. Think of it as an alternative to a skylight or light well and imagine the possibilities! It has often been used strategically, where many people can experience it, or as an eye-catcher. Parans solar lighting acheieves a valuable con-nection to the outdoor environment.

InStall the SP3

The installation should be planned closely before-hand, so that dangers and damages are avoided. We always recommend that the installation be performed by a professional, in order to avoid damage to the building. The receiver should not be connected to electri-cal power before all steps of the installation are complete.

The protective conduit protects the cables against damage from for example people or birds moving on the roof. It also protects the cables from UV radiation on the outside of the building. The pro-tective conduit should be shortened to reach just before the penetration of the building. The seal is made toward the bare cables, in order to make a tighter seal. Slide on the protective conduit before bringing the receiver to the roof.

Prepare penetration of roof and walls where nec-essary. Extra attention should be given the outer hole bringing the cables inside. This hole must be sealed well around the cables, in order not to leak water and heat. Parans recommends the use of Parans Cable Gland for sealing in facades and firewalls.

Always install conduit through walls, in order to facilitate installation and future service. Such con-duit needs to have an inner diameter of 50 mm to contain all six cables and bends must allow 50 mm bend radius for the cables. It is easier to duct cables in an uninterrupted conduit.

Measure and mark where the receiver should be mounted. The holes should match the foot of the receiver or optional roof brackets. The system is set to be installed in horisontal position. Brackets may be needed to level. Measure with a level to achieve an accuracy of ±2°.

If the system must be installed in tilted position, contact your reseller or Parans and we will help you make the setting. Maximum tilt is 45°.

Measure and mark where the roof or facade should be penetrated to allow passage of the optical fibre cables.Bring the solar receiver to the installation site.

The receiver weighs around 35 kg and should be handled by two persons. Handle the unit with care.

Drill all necessary holes for attaching the Parans receiver and ducting the optical fibre cables. Attach the optional roof brackets (see page 11).

Place the receiver on the drilled holes and optional roof brackets. Measure with a level that the foot is within ±2° from horisontal position.

Fasten the receiver in a secure manner. Extreme weather conditions of the area have to be taken into account. Make sure that the installation is secure for strong winds, snow and other weather extremes.

The outer hole needs to be sealed. Making a swans’ neck is one way of protecting from rain. Using the Parans Cable Gland is a solution for sealing tighter, at IP54.

Bring the cables through the planned path into the building. Make sure that the white marker is visible over the foot of the receiver. This ensures that the optical fibres are long enough to let the receiver rotate.

Taking into consideration the minimum bend radius of 50 mm, this step is done using normal cable duct-ing techniques. Always install conduit, as mentioned under the section Prepare. Make sure that the cable will not touch the unit as it rotates. Make sure it is not folded sharply or stepped on. Never pull sharply on cabling, as the fibres inside may be damaged.

Prepare an electrical outlet on the inside of the build-ing. It needs to be powered constantly, and should not be switched off by timers. The power supply unit does not sustain outdoor use, and should be placed next to the electrical outlet.

Do not connect the receiver to the power supply yet!

Before powering the unit, install the luminaires so that the light has somewhere to go!

Parans L1 can be suspended flush with the ceil-ing or pending down on wires. Depending on the ceiling material, different screws and plugs may be appropriate. Make sure that the luminaire is mounted securely!

Place the Parans L1 at the intended position and mark out positions for the metal hangers and their screws, see drill guide below and on www.parans.com

Make the appropriate holes in the ceiling for the screws and plugs that have been selected.

Mount the metal hangers, complete with the plas-tic washers, as shown in the illustration. Note that the hooks have a smooth and a sharp side. The sharp side must be upwards so that the plastic hooks suspend the luminaire safely.

Attach the optical fibre cable to the hole in the lu-minaire back sheet (the thinner of the two sheets), securing it with a nut.

Hang the luminaire by rotating the metal hangers and pushing the arrow-shaped part of the metal hanger into the plastic hooks.

Parans L2 is inserted into a standard 60x60 cm ceiling by simply replacing the ceiling modules.

Remove the two plastic reflector cups, unscrew the nut on each fiber cable and use these to at-tach the cables to the reflectors. Reassemble the luminaire.

For the hybrid version – connect the LED power supply to the electrical output. It is often easiest to first lift the luminaire through the grid structure and place it on the side of its place.

Insert the L2 luminaire into the ceiling grid.

Make a 45 mm hole into the ceiling or surface where the L3 spotlight should be recessed.

Screw the L3 spotlight to the optical fibre cable. Be careful not to twist the optical fibre cable - only rotate the spotlight.

Bend back the two long springs and insert the spotlight into the opening. The shorter arms of the springs remain in the opening, thus keeping the springs in tension.

When installing into thick materials (over 10 mm), the springs will not fit, but can be removed.

Make sure that the plastic end caps on each optical fibre cable are removed and that fibre cables are installed correctly into the luminaires before power-ing the unit.

Light from the optical fibre cables will be very con-centrated. Make sure that fibre ends are not close to skin, hair, clothing or other burnable materials. Do not look into the cable when starting up or operating the system.

A clear sunny day is needed for start-up! When the sun is visible on the sky, connect the power sup-ply to engage sun path. The Parans receiver will perform a start-up sequence in order to locate the sun and sync its sun path. Do not unplug the system during this sequence!

The start-up sequence takes less than one hour. As soon as the SP3 finds the sun, it will sync its sun path and keep following the sun. If the sky clouds over, do not disconnect the system. It will automati-cally keep searching until it finds the sun.

Please be patient when plugging in your system the first time! It will take a couple of sunny days to estab-lish a stable sun path, so do not unplug it. If you are experiencing problems during the installation, refer to the Trouble Shooting section on the next page!

Enjoy the sunlight!

Normal maintenance consists of cleaning with nor-mal cleaning agents and water 1-3 times a year.The cleaning is comparable to normal window wash-ing. In areas with a high content of particles in the air or many birds and bugs, cleaning may be needed more often.

The SP3 will track the sun as long as it is not buried in snow and ice so that it is blocked. If the glass is covered in snow, very little light will get focused into the optical fibre. In order to make it function, snow needs to be removed. Otherwise just wait for spring and the receiver will start working again.

The SP3 will protect its optics if heat builds up to over 60° C inside the receiver. It then needs to turn the lenses away from the sun, and the receiver will stop collecting sunlight. If this happens on a regular basis, the installation spot is not optimal and heat needs to be diverted.

Control that the sun is visible on the sky and is not covered by clouds. During night, some water drops may have condensed onto the lenses. This will dis-appear by itself as the sun comes out. The Parans system needs direct sunlight to work.

Control that the power supply unit is powered. This unit is placed indoors, by the electrical outlet.A green diod is lit when the unit is powered.

Control that the Parans receiver is not covered or shaded by nearby objects. If the glass is dirty, it should to be cleaned as mentioned under Mainte-nance.

Make sure that no nearby objects block the rotation space of the Parans receiver.

Control that electrical and optical fibre cables have not been broken or damaged.

If the problem remains, please contact your local reseller or Parans and we will assist. Please have the serial number of the unit at hand. Do not open the receiver on your own.

The small clamps are fastened to folds in the tin roof. Attach the bracket to the clamps. Measure where to place the clamps in order to match the foot of the system.

Fasten the clamps tightly around the fold using the lateral screw. Continue the installation as described on page 7.

Measure to decide the spacing of the two brackets.

The flat brackets are fastened with screws directly into the roof material.

Letting only the bolts protrude, the entire bracket can then be covered in tar paper, which is sealed with heat in order to make the roof water tight.The Z-brackets can be used on top, in order to raise the product from the roof. Continue the installation as described on page 7.

The Cable Gland is used to seal penetrations in external walls and firewalls along the cable path, creating a tight seal at IP54.

The rubber washer is placed over the opening before pulling the cables through. The rubber cubes are snapped onto the cables before placing them into the two plastic frames.

As the frames are closed with the two screws, a tight seal is created. The frame is then screwed in place toward the wall. Continue the installation as described on page 7.
