  • Page 3: Introduction

    Overview Heliocol solar heating systems can be either mounted on a roof or on the ground. In either case the collectors may lie directly on the mounting surface, or, if a change of angle is necessary, on a specially constructed rack.

  • Page 4: Conventions Used In This Guide

    Conventions used in this Guide Table 1: Icons used in this Guide Important: While this manual explains how to install Heliocol Solar Panels properly in typical situations, it cannot address all the possible individual cases. If you have any installation questions, contact your Heliocol representative for assistance.

  • Page 5: Basic Heliocol Terminology

    “panels”. You connect the supplied pane ls together to form “banks” of various lengths, depending on the individual requirements at your site. A Heliocol solar heating system consists of one or more banks of collectors, connected to the swimming pool filtration system.

  • Page 6: Designing Your System

    Designing your system This chapter describes the factors you need to take into account when designing your system, and the process of creating the plan of the system structure. Important: At 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.

  • Page 7: Preparing A Schematic Diagram

    Preparing a schematic diagram Once you have decided on the location for the panels, it is useful to prepare a schematic diagram of the system you wish to construct, taking into account the collectors sizes available. 1. Fill in a “Site layout sheet”. This will help you decide on the best system for your site. Prepare a schematic drawing of the installation area.

  • Page 8: Sample Collector System

    Sample system layout Figure 3.1: Sample collector system 1. Feed line to the farthest point from pump house and lowest point on system. PVC pipe connecting across a large obstruction Flat roof Return line as short as possible. Note: Full details of how to connect the supply and return pipes are given in Chapter 7. Page 6 Page 6...

  • Page 9: Mounting Racks

    Where there is no roof space, or not enough for all the collectors, you may need to construct a rack to mount some or all of the Heliocol panels. The rack must provide a stable base for the panels to be secured to.

  • Page 10: Parts And Tools

    Parts and tools Once you know the layout of your solar collector system, and how many panels/modules you require, this chapter will help you calculate which Heliocol and other fittings you will need to complete your installation. This chapter deals with the following three categories:...

  • Page 11: Heliocol Fittings And Accessories

    Heliocol fittings and accessories This section summarizes the four basic types of connection to and between Heliocol panels, using Heliocol fittings. Connecting between panels To connect a panel to a panel, you need 2 PPC connector sets. Each PPC consists of a clamp top and bottom, a rubber gasket, and a latch, one to connect the upper manifolds and one to connect the lower manifolds.
  • Page 12 / nut on display. On an IBR / Harvey Tile Roof the best method is to use a wide shoulder Pop Rivet followed by waterproofing. Heliocol fittings summary Page 10 Page 10...

  • Page 13: Hydraulics

    Hydraulics This chapter deals with the hydraulics that needs to be considered before installation. Panel configurations Before you can start constructing the system you have designed, you must consider how the banks will be connected together. You must also take into account the maximum number of panels allowed per bank, as shown below.

  • Page 14: Basic Plumbing & Array Layouts

    Basic plumbing & arrays layouts SINGLE BANK WITH OBSTACLE Split around the obstacle or over the parapet or split level roofs Page 12 Page 12...

  • Page 15: Plumbing

    Plumbing Water inlet /outlet Inlets are always connected to a lower end of the bank; outlets to the upper corner diagonally opposite. Using the “Reverse return” (Tichelmann) method would ensure balanced flow in all collector banks. Pipe diameter It is important that all plumbing connected to the system uses a diameter of PVC pipe appropriate to the size of your solar array.

  • Page 16: Pump Power

    Pump power The power of the swimming pool filtration pump must be adequate to supply the Heliocol system with the minimum recommended flow rate necessary for the number of panels being installed. These recommended rates in litres per minute are: For example: If you were installing ten HC-40 (4’x10.5’) panels, your pump would have to be able...

  • Page 17: Automatic Drainage

    To assist drainage a vacuum breaker is installed on the solar feed line above the 2-way valve, as shown in the drawing on page 19. Important: Heliocol Solar Pool Panels are warranted against internal freezing on condition that they are installed to allow for automatic draining.

  • Page 18: Installation

    Installation This chapter describes four basic installation processes: Connecting panels together Connecting panels across an obstruction Securing panels to the roof (sloping or flat) Gluing PVC joints Connecting panels together Lay the two panels side by side with the panel spacer bars facing down.
  • Page 19 Place the bottom half of the plastic panel clamp under the header end with the larger, flat portion facing away from the panel and the male “hook” aligned with the riser pipes. THIS IS MOST IMPORTANT. Any other position will result in damage to the panel, as the other parts of the PPC are too wide to fit between the risers.

  • Page 20: Bypassing A Small Obstruction

    Bypassing a small obstruction Small obstructions can sometimes be bypassed simply by unclipping some risers from the spacer bars and spreading them to either side of the obstruction. Figure 6.1: Bypassing a small obstruction Important: If the obstruction is between one of the headers and the adjacent spacer bar this method must not be used, as it might cause a riser to become detached from the header.

  • Page 21: Connecting To The Existing Equipment

    That way you will know exactly where the pipes should come down from the roof. However, if you will be trenching from the existing equipment to the Heliocol installation location this is not necessary. Feed and return lines Feed and return lines are connected using a PPC connector and a CPVC adaptor.

  • Page 23: Plumbing Guidelines

    Plumbing guidelines The figure above shows how a typical Heliocol Solar Pool Heating System is plumbed into existing pool plumbing. Even if your system is not identical to the one shown, the illustration can help you understand the flow of water from the pool, through the pump, filter, solar system and back to the pool.

  • Page 24: Automatic Systems (Private & Public Pools)

    Automatic systems (Private & public pools) The basic difference between the manual system just outlined and an automatic system is the use of a motorized 3-way valve, which is controlled by two sensors. In cloudy weather the connection with the pool is automatically shut off so as to maintain the warmest temperature possible. The two sensors will read: (1) temp of cool water coming from the pool and (2) the heat of available solar radiation.
  • Page 25 Public pool basic plumbing The additional booster pump should be installed after the lter, using a “T” joint on the main ltration pipe. The automatic control commands both the booster pump and the 2 way valve after it. (The 2 way valve is installed in order to prevent undesired low water flow through the collectors caused by the main filtration pump).

  • Page 26: Operation

    Operation Turning the system on (manual systems) 1. Turn the pool pump off. 2. Turn the 2-way valve to the “closed” position. Solar ON 3. Turn the pool pump on. 4. Set the pool pump timer, if used, so that the pump will run when sun is shining on the solar panels. Usually 8:00 AM to 4:00 PM, but this will vary with geographic location and time of year.

  • Page 27: Troubleshooting

    Troubleshooting This troubleshooting section will help you identify and solve any problems as quickly as possible. There are air bubbles in the pool when the solar heater is operating Diagnosis #1: There may be air coming into the pump through an air leak on the suction side of the pump due to the pump working harder to move the water through the solar system.
  • Page 28 Some of the solar panels are warm to the touch while others are cool Diagnosis: There is not equal flow through all of the panels. Warm panels indicate low water flow. Pump Answers: 1. Check that the filter is clean. Backwash to reduce pressure. 2.

  • Page 29: Replacing A Damaged Riser Tube

    Replacing a damaged riser tube In the event of a riser getting damaged and leaking, one of the advantages of Heliocol collectors is the ease with which the leaking riser can be removed, the leak repaired, and a replacement riser attached to maintain the uniform appearance of the panel.
  • Page 30 Spray the rubber sleeve with silicon spray and pull it over the small metal pin of the Heliocol repair handle. Stretch and relax the rubber sleeve couple of times over the metal pin. Using the repair handle gently push the rubber sleeve into one of the holes created by the removal of the riser, until only the head is showing.
