1. Introduction

Before attempting installation, read the instructions in this manual carefully. This manual contains easy to follow step-by-step procedures to property install our Techno-Solis pool solar system. Your understanding our system and it parts will assure a successful, trouble-free installation. If you have any product or installation questions regarding this installation, contact our representative at your nearest area.

It is important to recognize that this manual outlines the recommended installation methods and practices as prescribed by the factory. It is designed to aid the installer or even the novice through providing optimum protection for the products. Also, these are the minimal requirements; additional protection may be required in hazardous environments or in areas subject to extremes of weather. In those areas, the local expertise of the contractor may be relied upon in coordination with our approval for special installation considerations.

Take time to read through this manual. It will guide you through the most e cient way to correctly install our pool solar system. By following this step by step guide, your system will meet the installation standards recommended by the factory. In addition, because we’ve included techniques and tips gathered from experienced SUNDWARE contractors throughout the countries, using this installation will save you time and e ort.

2. Getting Started

Before you begin your installation, here are a few important advices:

1. Caution- Safety Comes First !!!!

• There is no substitute for safety. Always exercise extreme caution, care and good jud ments when working on or around a roof or pool area.

• Please take care to avoid hazards such as over-head electrical wires or loose shingles or roof tiles.

• Be sure to secure ladders so they will not slip or fall.

• Do not allow extension cords to lie in the pool or in standing water.

• Wear shoes with proper tread to prevent slipping on the ladder or sloped roof areas.

• Disconnect all power to the pool equipment when installing an automatic control system.

2. Before starting any work, determine the location of your system and prepare a schematic

drawing of the installation area. Include the location of the feed and return lines in this drawing. Roof areas often times look bigger than they really are, so be sure to measure the available area before making your schematic.

3. The planned placement of the panels should allow the panels to drain when the pool pump

shuts o .

4. The paint of the outdoor pipes and  ttings should be UV resistant. Painted pipes and  ttings

will require additional maintenance.

5. Never walk on collectors when they are wet as they present a signi cant slip hazard. Walking

on the collectors should only take place when absolutely necessary.

6. Familiarize yourself with all of our pool solar components and plumbing materials that are

needed to complete the installation.

3. Pipe and Pipe Fittings

Use pressure rated Schedule 40 PVC pipe. You may prefer to use black, but because black PVC can be di cult to  nd, some installers have inquired about the use of black ABS pipe instead. DO NOT USE ABS PIPE. ABS pipe does not have the UV inhibitors that PVC pipe has, causing ABS pipe to become brittle and to crack after several years of exposure.

Use PVC Schedule 40 pressure-rated ﬁ ttings to match your PVC pipe. Be sure NOT TO USE “plumbers” ﬁ ttings or DWV ﬁ ttings (drain, waste and vent).

4. Cleaner and Cement

Refer to the product’s label for selecting good quality Cleaner and CPVC all-purpose cement. Before applying the cement, be sure to clean each ﬁ tting and pipe end with the PVC Cleaner or “primer.” Soon after cleaning each part, apply ample cement ﬁ rst to the ﬁ tting and then to the pipe end. Insert the pipe end into the ﬁ tting with a slight twisting motion until it seats to evenly distribute the glue. Hold it in this position for 5 to 10 seconds to allow the joint to set up. Finally, wipe excess cement off of the joint and pipe.

Note: Cold weather slows the set-up process for PVCglue. If installing in colder climates, refer to the PVC glue manufacturer’s charts for curing times.

5. Panels and Installation Kits

Planning ahead and having the proper partsand kits for your system will make your installation much easier. The kits and parts that are useful for our systems are shown here below under the title “PARTS LIST ”.

The Solar pool system has the following components (see  gure 5)

1. The SUNDWARE PANELS are the key to your system. They absorb the sun’s heat e ciently

and transfer the energy to the swimming pool water that is pumped through them.

2. The SOLAR ROOF SENSOR* is installed beside the SUNDWARE solar panels to sense the

heat from the Sun. It relays the solar panel temperature to the automatic control.

3. The POOL WATER SENSOR* is installed in the pool plumbing, after the  lter. It senses the

pool water temperature and relays the information to the automatic control.

4. The AUTOMATIC CONTROL and MOTORIZED 3-WAY VALVE* compare the pool water tem-

perature to the solar roof temperature to turn the SUNDWARE solar heating system on or o , as required.

5. The existing PUMP and FILTER circulate clean water to the pool and through the solar

panels when required.

6. The END CAPS seal the solar panel headers at the end of the row.

7. The LAG SCREWS and WASHERS are used to secure mounting straps to the roof.

8. The MOUNTING STRAPS are used with lag screw and washer to secure the solar panels to

the roof.

9. The EPDM HOSES connect the SUNDWARE solar panels together and connect the piping

to the solar panel array.

10. The CHECK VALVE* is used to prevent back ow circulation in the solar panels at night.

(1/8” diameter hole to be drilled in the  apper to allow for winter drainage).

11. The “U”STEEL SUPPORTS are used to anchor the top header of the solar panels.

* Only used in systems with automatic control.

Some systems will use a manual valve for turning the system on or o .

8. Installation

8.1 Before You Start

Please read the complete manual before starting. If you have any installation problems or questions, consult SUNDWARE GROUP’ distributor. Remember, serious damage may result from malfunction of the system and its components if instructions are not closely followed.

Check local plumbing, electrical and building codes. The installation must comply withthe local regulations, which vary substantially from location to location.

8.2 Array Size

The number of solar panels required in the array is primary dependent upon the surface area of the pool and the amount of solar energy available in the area of the installation.

The relationship between solar panel area and pool area should be: (for summer heating).

50% if solar panels are SOUTH facing

75% if solar panels are WEST facing

80% if solar panels are EAST facing

75% if solar panels are laid  at (with a minimum of 10 degrees inclination for properdrainage)

8.3 Space Required For Array

The minimum linear space for an array can be determined by the chart shown in  gure (6). Add any length required to bypass roof obstructions.

The minimum vertical space required is equal to the length of the solar panel (8’, 10’ or 12’) plus 6” (150 mm) for the feed and return pipe runs above or below the array. Add a slope of 1 inch in 10 ft. (25mm per 3 meters) for the feed and return pipe runs to permit drainage.

8.4 Flow Rate through Array

The recommended  ow rate through the array is 3 to 10 GPM (11 to 35 liters) per panel. A  ow rate of 5 GPM (18 liters) is recommended. The actual  ow rate is not that shown on the pool pump because of pressure losses in the system. The actual  ow rate may be determined by using an in-line  ow meter or calculated the time it takes to  ll a bucket of known capacity.

8.5 Control Module Location

Determine the location of the electronic control based on access to power, ease of cutting into existing piping at the  lter outlet, and piping to and from the array. (Refer to the control manufacturer’s instructions).

8.6 Pipe Size

Determine the length and size of the pipe required. Use only PVC pipe. Black ABS piping degrades when exposed to sunlight. Use pipe cleaner before gluing with PVC glue. If connecting to ABS piping, use PVC glue, not yellow ABS glue. Allow several hours for glue to set before turning on pump.

For runs of less than 80 ft (25 meters), either feed or return, use 1 ½” pipe. For runs of more than 80 ft. (25 meters) a 2” pipe is recommended. Pipe runs should be planned so that the panels and piping drain when the system is not active.

8.7 Piping Arrangement (Figure 7)

a. Always pipe the array reverse-return. End-feed end-return systems are not e cient.

b. If possible, install the return pipe at the top of the array; this will eliminate the air in the

system.

 Solar Pool System

Installation Manual

Page 11

c. Feed at the lowest point in the system and connect the return line from all panels to the

highest point in the system.

d. All piping should be sloped continuously downward, towards the existing pump and  lter.

If there are any low points or traps in the piping, drain plugs should be installed to ensure complete drainage if the installation is an area subject to freezing conditions.

e. For multiple level, or split arrays, ensure that all return piping rises to a common high

point. Use abank kit (K15BKB) for multiple rows and a split kit (K15SPLB) for roof obstructions (see the part list of the pool systems in para 5).

Fig (7): Typical Panel and Piping Arrangements

8.8 Layout of the Solar Panel Array

a. Determine the exact location of the array, based on the required array con guration, the

existence of roof obstructions, proper feed and return pipe runs, shading of the panels and any other speci c factors that may a ect the location of the array.

b. Utilizing a chalk line or string, make a horizontal line across as a reference for where the top

header of the panels will be located. Allow su cient room between the headers and the roof line for pipe runs. Care must be taken to make the horizontal line truly horizontal. For maximum protection against freezing, slope the entire array toward the feed pipe. The slope should be 1” per 10’-0” (25 mm per 3 meters).

c. Carefully check the roof, where the array is to be mounted, for any sharp projection (nails,

screws, etc.) that may damage the solar panels.

d. If the array is to be on multiple levels, or split roofs, repeat steps 1 through 4 above for each

portion of the array. Ensure that all return piping rises to a common high point.

8.9 Solar Panels

The SUNDWARE solar panels are designed to resist expansion and contraction due to temperature variations. Even though the panels are made of resistant thermoplastic materials, care should be taken when they are handled to avoid contact with sharp surfaces. When lifting the panels onto the roof, take care not to damage them by dragging them over the edge of the roof.

8.10 Assemble the Solar Panel Array

The headers of adjacent panels are joined to each other by an EPDM hose (item # 9), with two stainless steel gear clamps. Do not over tighten these clamps as it may cause the end of the header to collapse. Care must be taken to ensure that the stainless steel gear clamps are placed to match the groove in the header.

1. On the ground, prior to lift the panels on the roof, place an EPDM hose on one end of the headers of each panel. Do not tighten the gear clamps, unless required to do so because of wind or roof slope (see  gures 8 and 9).

a. Place the second panel beside the  rst so that the top headers are approximately 2 to 3”

(5 to 7 mm) apart.

b. Snap the top header of the second panel into the EPDM hose of the  rst panel.

c. Rotate the bottom of the second panel toward the  rst panel, and then snap it into

postion.

d. Tighten all gear clamps.

e. Repeat assembly procedures until array is complete.

2. Roof obstructions (see  gure 10) or split arrays (see  gure 11) require that a PVC grooved pipe to panel adaptor be inserted into the EPDM hoses. Each obstruction, or split, requires a split kit (see the part list in para 5-Optional Items).

Fig (10): Split Kit Fig (11): Bank Kit

3. When an array has been assembled, it is ready to be secured to the roof. Adjust the array so that the headers are sloped 1” per 10’-0” (25 mm per 3 meters) towards the feed line.

4. The feed line will be connected to the lowest point in the array and an end cap (item #6) will be installed at the other end of the array in the bottom header.

5. The return line will be connected at the highest point in the array, opposite of the feed line, and an end cap (item #6) will be place in the other end of the top header of the array. Consult  gure (7) for double bank arrays.

8.11 Mounting the Solar Panel Array

1. Starting at either end of the array, install a “U” steel support (item #11) over a top header EPDM hose and anchor to the roof using two lag screws and washers (item #7). Make sure to place a generous amount of caulking material on the roof at the point where the screws will penetrate the surface (see  gure 13).

2. Repeat this procedure across the array, securing a “U” steel support over each top header EPDM hose. Only the top header of the array should be anchored in this manner.

Fig (13): Panel Mounting Details

3. For the installation of the  rst mounting strap, locate a point on the roof approximately 12” (300 mm) above thebottom header and 2” (50 mm) out from the edge panel. Tie a knot in the end of the mounting strap (item #8), insert ina lag screw and washer, put caulking mate-

rial and anchor to the roof. Extend the mounting strap across the array to theopposite end. At this point, pull the strap tight, tie a knot, put caulking and anchor it to the roof using a lag screw andwasher, 12” (300 mm) up and 2” (50 mm) out from the edge of the last panel. Anchor mounting strap between eachpanels using lag screws and washers. Always use caulking when penetrating the roof.

4. Using the same procedure as in step 3, attach a second mounting strap at 18” (460 mm) below the top header and athird one across the center of the array (see  gure 14). For 12’-0” panels, install across the array, a fourth mountingstrap equally spaced between the other mounting straps.

Fig (14): Mounting Strap Arrangement

8.12 Flat Roofs

Flat roofs are more delicate to work on. Exercise extreme caution to prevent roof damage. Solar panels can be mounted on  at roofs if the length of the panels is sloped a minimum of 12” (300 mm) to ensure a good  ow rate through the panels and to enable them to drain. A framework, illustrated in  gure (15) made of 2” x 4” and 2” x 6” boards, will support the solar panels along their length. All wood products must be pressure treated, exterior grade. This support should extend a minimum of 6” (150 mm) around the panel array to support the feed and return pipe runs.

8.14 Plumbing the System

1. Feed and return connections to the array are made by inserting PVC grooved pipe to panel adaptor into the panel EPDM hose and gluing the PVC pipe to the adaptor. Never attempt to glue pipe directly to the solar panel header (see  gure 12).

2. An end cap (item #6) must be plumbed into the array at the opposite end of the bottom header to the feed line. If necessary, this end cap will totally drain the panels when the system is winterized. More end caps can be used in the plumbing to facilitate drainage.

3. Isolating valves (optional), plumbed in the array feed and return lines, near the electronic control, are recommended so that the array can be isolated if desired.

4. With a pool  ltration system far from the house, where the solar panels are installed, feed and return lines are buried (see  gure 19). Flexible corlon polyethylene piping is suggested because it is more resistant to freezing. Rigid PVC pipe may freeze and break. Install drain plugs at the both ends of the underground pipes using the underground kit K15UNG (see para 5 –Parts List).

Fig (19): Underground Kit

5. Insulation is not needed since the pool water temperature and ambient air temperature are almost the same. Winter conditions of snow and ice make it imperative that the system be checked once a year by a quali ed installer: solar panel mounting straps, sensor wire, caulking, piping fastening and pipe drainage.

 Solar Pool System

Installation Manual

Page 20

8.15 Plumbing Connections

1. Make a mock up with pipe  ttings and the manual or automatic controller, to determine the piping requirements. Follow the instructions supplied by the manufacturer of the controller.

2. After determining size requirements, cut out the appropriate amount of existing piping.

3. Convert to PVC pipe with threaded adaptors. Always use Te on tape on threaded joints to avoid leakage.

4. Feed and return piping should go around overhanging eaves to minimize risks of leaks.

9. Installation Procedure

The following procedure assumes a shingle roof:

Step (1): Establish a horizontal chalk line across the roof for the location of the top of the system.

This line must have 3/4” clearance above and below it for mounting the Header Clip on a flat surface. For tile roofs, the line should be approximately 2” above the bottom of the tile.

Note: For seasonal climates, this line must have a ¼” per foot slope towards the feed line to allow for drainage and winterization. Then drop a vertical line (90° to the horizontal line) at the left or right end of the installation to locate the first panel. Allow a minimum of 3” on all sides of the panel row for piping. Inspect the roof for any sharp projections that may damage the panels.

Step (2): Lay out the system before securing any panels. Begin installing the panels on the left working right towards the opposite end. The panels can be installed with either side up, and should be flipped after five years to lengthen their life.

Step (3): Lay the top header approximately 1¼” below the horizontal chalk line. Using the parts from the Panel Kit, install a 3” Rubber Coupling on the top right and bottom right header outlet. Slide a Hose Clamp over each Rubber Coupling and position it over the groove in the header. Rotate the head of each clamp facing up for easy access, shown in Fig (20). Then tighten until snug.

Step (4): Slide another Hose Clamp over the top and bottom Rubber Coupling. Position the next panel to the right of the first panel, and insert the header outlet into the top and bottom Rubber Coupling of the first panel. Position each Hose Clamp over the groove of the second panel; facing up for easy access. Then tighten until snug. The top and bottom should resemble Fig (21) when finished. If the roof is not too steep for the panels to slide, you may continue connecting panels following Step 3 then Step 4; otherwise move to Step 5

 Solar Pool System

Installation Manual

Page 21

Step (5): Verify that the panels are in position (the top edge of the header should be parallel to the horizontal line; the left edge of the very rst panel should be on the vertical line). Place a U-Shaped Bracket over the upper Rubber Coupling and mark the roof where the Hex Screw will penetrate. Remove the U-Shaped Bracket and apply a generous amount of sealant to the marked areas on the roof. Return the U-Shaped Bracket. Using a drill and a 3/8” nut driver, drive two Stainless 3/8 Hex Screws through the holes of the Bracket and into the roof.

Note (1): The U-Shaped Bracket should be tightly secured but be sure not to over tighten the screws and strip the wood. When installed it should resemble Fig (22). Finally, apply sealant around the head of the screws.

Note (2): The bottom headers are NOT secured with U- Shaped Brackets to allow for expansion. Continue with Step 4 and Step 5 until all panels in the row are installed.

Fig (20): Rubber Coupling Fig (21): Rubber Coupling Installed

Fig (22): U-Shaped Bracket

 Solar Pool System

Installation Manual

Page 22

Step (6): Install a Rubber Coupling on the four outside remaining header corners using the Hose Clamps. On the feed and return corners, insert the Pipe to Panel Adapters, seen in Fig (23), into the Rubber Coupling using the end that resembles a header outlet. Secure with a Hose Clamp. On the upper remaining corner, insert the vacuum breaker assembly, Fig (24), and secure with a Hose Clamp. On the bottom remaining corner, insert an End Cap and secure with a Hose Clamp, Fig (25). Secure the nal two top Rubber Couplings to the roof with U-Shaped Brackets just as you did in Step 5.

Step (7): The Hold-Down Straps may now be installed- Fig (26). A minimum of 3 straps is required In high wind areas increase the number of straps per panel row, particularly for the longer panels.

Fig (23): Pipe to Panel Adapter Fig (24): Vacuum Breaker Assembly

Fig (25): End Cap

 Solar Pool System

Installation Manual

Page 23

The bottom Strap is always located 12” above the bottom header. The remaining Strap(s) are equally spaced between the bottom Strap and the top header. You may want to use a chalk line to mark this spacing before you install the panels by measuring down from the top horizontal line; or use the shingle lines as a guide.

Install SuperClips along the marked lines between all panels and at the ends of the row, Fig (27) To install a SuperClip, apply a generous amount of sealant to the base of the clip. Place the base on the marked line and secure with a Stainless 3/8 Hex Screw through the center hole of the base, Fig (28).

The SuperClip base should be tightly secured but be sure NOT to over tighten the screw and strip the wood. In high wind areas the base can be fastened in the four corners in addition to the center.

Lay strap across the SuperClip base at the left end of the row. Screw on SuperClip cap rmly. Stretch the strap across all the panels to the right and screw on the last SuperClip cap rmly while the strap is under tension Fig (29). Now working from the center towards the ends of the row, screw each cap on rmly.

After the system is installed for several weeks or even months the Strap may need to be re-tensioned due to expansion of the strap in warmer weather.

10. Bottom End Plumbing

A typical plumbing layout is shown in Fig (30). The tie-in for the solar plumbing is always downstream of the lter. You may use 1½” PVC pipe for the bottom end plumbing; however, you should use 2” PVC pipe where possible. 2” PVC pipe is recommended above the 3-way and tee.

Always use PVC cleaner on all pipe ends and tting sockets. Use a generous amount of PVC glue on pipe ends and tting sockets, immediately inserting with a twisting motion. Hold together for at least 30 seconds. Follow the instructions on the cleaner and glue can for proper use. Determine the layout of all the valves and ttings before proceeding. Cut the line after the lter in an area with enough clearance for the new ttings. Install a check valve between the lter and the 3-way valve, with the ow pointing away from the lter (the cone inside the check valve will be facing towards the lter). Be certain not to allow glue to seal the cone inside the check valve.

Typically the 3-way is mounted against the wall of the building approximately 3’ to 4’ o the ground with the side outlet facing right and the inlet facing down. Use a 2½” galvanized pipe clamp over the bottom inlet of the valve to secure it to the wall with screws. Plumb into the “inlet” of the 3-way valve from the check valve. The plumbing then continues up the wall, around the eave and onto the roof feeding the solar panels. The side outlet of the 3-way valve connects to the side outlet of the 2” tee. The return from the solar connects to the top of the tee. The bottom of the tee returns to the line going to the pool jets. Install a check

Fig (30): Bottom End Plumbing

 Solar Pool System

Page 25

valve on the solar return line above the tee, with the direction of ow going into the tee. Most accessories including auxiliary heaters, chlorine feeders, Pool cleaner pumps should be on the return line after the tee. Automatic pool cleaner pumps must be run at night when the solar is o or during the day only after the solar is already running. Failure to do so may result in a burnt-out cleaner pump.

11. Pipe Layout

Use 2” Schedule 40 PVC plastic piping between the bottom end plumbing and the panels. White pipe is recommended because of its excellent outdoor life. The pipe may be painted with a good outdoor paint to match the structure or roof. 1½” pipe may be used on splits between panel rows. All plumbing should allow for gravity drain. In tropic or sub-tropic climates, the panels and plumbing may be level; in northern climates, they must be installed with a ¼” per foot slope towards the pool equipment. The panels should gravity drain back to the pool. If it is not possible to route plumbing to allow for panel drainage, a manual drain valve or line should be installed, or the end plugs may be removed to drain panels. Support all pipes every 4’ using 2½” Galvanized Pipe Clamps.

12. Control Installation

12.1 Solar Controls

Several types of solar controllers are available. The most common utilize a 3-way diverter valve (see  gure 32) todivert water from the normal  lter loop to the solar panels. Other models use a 2-way valve (see  gure 31) to blockwater from the normal  lter loop, forcing it through the solar panels. Both 3-way and 2-way are currently available inautomatic or manual versions. Some automatic systems have a manual over-ride which allows manual operation ofthe valve without electrical power.

Fig (31): Manual Control

Fig (32): Automatic Control

 Solar Pool System

Installation Manual

Page 26

With very few exceptions, all solar controllers are compatible with our Techno-Solis solarpanels. The major considerations in selecting a control system should be:

• reliability and proven track record,

• availability of servicing should something go wrong,

• conformity with local electrical and plumbing codes,

• Compatibility with planned installation, i.e. 2-way valve systems often cause signi cant heat losses from night timecirculation if solar panels are at the same height, or below, the pool and cannot drain when the system is o .

12.2 Typical Automatic Control System

Automatic control systems will turn on and o the Solar Heating System depending on availability of energy and the set temperature of the pool. Most controls operate a 2 or 3-way valve to divert water to the solar panels.

The following describes a typical 3-way automatic control system, its components and operation (see  gure 32).Always refer to the SUNDWARE catalog for the exact details of operation, maintenance and installation.

Mount the automatic control system in a convenient location near the pump and existing pool piping. In most pool con gurations, the pump draws water from the skimmer and the main drain. It then pushes water through the  lter, the existing accessories (water treatment, conventional heater, etc...) and back to the pool. Plumbing connections for the automatic solar controller are made between the  lter and the existing accessories, so that the solar heated water can return to the pool via the existing accessories-if there is one (see  gure 33).

Fig (33): Piping Diagram

 Solar Pool System

12.3 System Check Start-Up

1. Turn the pool on and let it run 10 minutes before turning on the Solar Pool Heating System.

2. Turn the automatic controller to the “ON” position and for the manual controller open the 2 or 3 way valve slowlyand check the following:

a. the pool  lter pressure gauge will indicate an increase in pressure.

b. the pool outlets may bubble for a few minutes as the air in thesolar panels is purged.

3. Retighten all EPDM panel hoses while the system is on and check piping for leaks.

4. Touch the surface of the panels. The surface of the solar panels should be cool to the touch as the water in thepanels absorbs the sun’s energy. If the solar panels are uniformly cool to the touch, then our SolarPool Heating System is operating properly.

12.4 Typical Automatic Control Components(see  gure 33)

• the electronic control box, 110 or 220 volt (2)

• the motorized 3-way valve, 24 volt (3)

• the solar roof sensor (5)

• the pool water sensor (4)

12.5 Typical control Operation(Les Fonctions

du ContrôleAutomatique)

When the pool pump is running:

1. “AUTO, TEST ON or OFF” switch:

AUTO: when the switch is in this position, the control will automatically divert water  ow to

thesolar panels if su cient solar energy is available and the pump is on.

TEST ON: the water  ows through the panels, regardless of the pool temperature or the solar

energyavailable. Often uses for night cooling.

OFF: The panels are bypassed and the water  ows directly to the pool.

2. Thermostat:this should be positioned to turn o the Solar Pool Heater when the selected temperature has beenreached.

3. Green Light “FLOW THRU COLLECTORS”:this light will come on whenever the water is diverted to the solar collectors.

13. Special Roof Requirements

Variations in the installation procedures are outlined below. Consult the technical support for other types of roof installations.

13.1 Flat Tile or Barrel Tile Roofs:

The mounting hardware is attached to the tile using Tapcon Screws supplied with the kit (you must specify tile roof when ordering). This requires drilling a pilot hole in the tile before inserting the screw. Use a 3/16”masonry drill bit. DO NOT drill into the substrate below the tile; doing so will cause a roof leak. The mounting screws should be positioned 1”to 2”above the bottom edge of the tile. This will allow a space between the tile and the substrate due to the overlap in the tiles. On barrel tile roofs, try to lay out the panels so that the mounting holes fall on the tops of the barrel tile. This can be accomplished by using 6” rubber couplings where additional spacing is required; cut the coupling to the correct length.

13.2 Cedar Shake Roofs:

If the cedar shakes are installed on top of a plywood surface, use a galvanized metal  ashing (approximately 4”x4”) under each shake where the mounting screw will penetrate. Center the  ashing under the penetration location before installing the screw. Drill a pilot hole and apply a generous amount of sealant into the hole. If the cedar shakes are installed on  r strips, call for alternate installation method.

13.3 Flat Built-up Gravel Roofs:

Use caution when installing on this type of roof. The preferred method is to have a roo ng contractor install “roof curbs” where the mounting hardware will be installed.

13.4 Open Beam Roofs

Any ceiling with exposed beams must be checked to avoid the screw ends from penetrating into the interior space.

13.5 Metal Roofs

If the metal roof is installed on a plywood surface, you may proceed using the normal installation method. If the metal roof is installed on  r strips, the mounting hardware must penetrate into the  r strip to insure a good seal and to avoid bending the metal surface.

13.6 Rubber or Asphalt Modi ed

This type of roof is typically installed  at. Using a 2” to 2-½”fender washer under the mounting hardware will provide additional mounting surface. Be sure to use a generous amount of sealant under the washer, between the washer and the mounting hardware, and the top of the mounting screw.

13.7 Roof or Ground Mounted Rack Systems

Rack systems can be made from pressure treated wood or aluminium. For roof mounted racks aluminium is preferred for its additional strength and longevity. Aluminium racks are available in a kit form.

 Solar Pool System

Installation Manual

14. Operating and Check-Out Procedures

1. Final Visual Inspection

Check the following items:

• Verify that the check valves, control valves and vacuum breakers are installed properly.

• Verify that all plastic collector clamp clips are tight.

• Verify that all lag bolts are secure and that adequate sealant was used to prevent any roof leaks.

• Be sure all collector riser tubes are snapped into the spacer bars (except where they go around obstructions).

• Be sure that collector riser tubes are NOT rubbing on the roof surface between spacer bars. If they are, adjust spacer bars as needed to prevent this or a hole may develop in the riser tube.

• Be certain that the system will automatically drain down when the pump is shut o or that enough manual drain valves have been included.

• Verify that all pipe runs are properly supported with pipe clamps.

2. Turning the System On

• Turn o the pool pump.

• Turn the 3-way valve so that the “closed” indicator points toward the pool side of the valve.

• Be sure that the ball valves on the feed and return lines are open.

• Turn the pool pump on.

• Set the pool pump timer, if used, so that the pump will run when sun is shining on the solar collectors. Usually 10:00 AM to 4:00 PM, but this will vary with geographic location, time of year and the compass location of the system.

• When the solar system is running, you should notice: “Aslightly higher pressure reading on the pressure gauge”.

At midday, if the sun is out, warmer water should be coming into the pool. This water should

be 3 to 5 degrees warmer than the pool temperature.

All the collectors should feel cool to the touch when the sun is on them. (If they are not, see

the troubleshooting section).

• During the cooler months of the year, it is essential that the pool surface be covered at night with a “pool blanket” to maintain a comfortable water temperature. Low nighttime temperatures can lower the water temperature more than the solar can recover during the day.

 Solar Pool System

Installation Manual

Page 30

3. Turning the System O

• Turn the pool pump o .

• Turn the 3-way valve so the “closed” indicator points toward the solar side of the valve.

• If isolating the collectors, close the ball valves on the feed and return lines after you are sure all the water has drained out of the collectors and plumbing.

• Turn the pool pump on to  lter the pool as needed.

15. Troubleshooting Guide

The troubleshooting guide outlines procedures for determining and correcting problems which may occur with the SUNDWARE Solar heating System. It deals with problems, components and corrective action. Several common problems are outlined with simple corrective measures which may be made by the homeowner.

SN PROBLEM COMPONENT “C”

Air bubbles in the pool during the operation of the system

Filter is dirt Dirt in  lter reduces  ow to collectors.

Vacuum relief valve of the pump (if available). No enough water pressure in the solar system to keep the vacuum relief valve closed so it is allowing air to be drawn into the water as it  ows by the valve.

a. Backwash to reduce pressure. b. If an older system, check for debris or scale in the mouth of the

vacuum relief valve and clean (if necessary).

c. Move vacuum relief valve, and put solid end cap at end of top

header where vacuum relief is located.

d. Install a2-Way Valve on the return line to throttle the  ow back to

produce more back pressure on system. e. Eliminate the Vacuum Relief Valve. f. Increase pump horse power.

Pump is making noise, which could make the air coming into the pump because the pump is working harder to move the water through the solar system

a. Tight the pump trap lid. b. Check, clean, lubricate or replace the O-ring on the pump trap lid. c. Remove the suction pool cleaner (if available). The air bubbles

should be improved. Use it only during the o of the system. d. If you have a clear lid on the pump and can see air bubbles in the

trap, using a garden hose, run water over the lid and each joint

individually to see if the air bubbles clear up. If there is not a clear

lid, listen to pump noise for a smoother operation. Repair any air

leaks.

nates the problem, use it only when the solar system is o .

If the system is a single row array

a. If there is adequate  ow, install an HC-152 Two-Way Valve on the

return line to throttle the  ow back to produce more back pres-

sure on the system. This will even out the  ow through the panels. b. If the array contains more panels than the maximum recommend-

ed on Page 9 of the manual, change the array to a double row or

single row split feed as shown in Fig 4.2 and Fig 4.3.

If the system is a double row or a single row split feed array.

a. If there is adequate  ow, install an HC-152 Two-Way Valve on the

return side of the set of panels that are the coolest to throttle

back the  ow through these panels and force more through the

warmer panels. b. If any section of the array contains more panels than the maxi-

mum recommended on Page 9 of the manual, make changes as

needed to correct this.

The water coming from the solar system is not as warm as it should be

The water is  owing to fast through the panels.

Water  ow through a single panel should be less than 10 gallons per minute. Adjust the Three-Way Valve to by-pass some of the water
