  • Page 6: Introduction

    INTRODUCTION ABOUT YOUR FLAT PLATE SOLAR COLLECTOR Your Flat Plate Solar Collector is designed to offer reliable hot water heating in hot, mild, or cold climates. Flat plate solar collectors operate in open loop, closed loop, and drain back solar systems, making these collectors ideal for a variety of installation designs.

  • Page 7: High Temperatures

    PART 2 – IMPORTANT INFORMATION A. SCOPE OF MANUAL This manual pertains only to the installation and operation of the HTP solar collector. Details for the installation, operation, and maintenance of the complete solar gas/electric water heating system, including, but not limited to: the storage tank, gas/electric booster, pump, system controller, valves, and other plumbing components, should be provided separately by their respective manufacturers.

  • Page 8: Local Standards And Authorized Persons

    The term “authorized person(s)” used throughout this document refers to a suitably qualified professional. Unless otherwise specified in Part 3, no part of the HTP solar collector may be inspected, repaired, or maintained by anybody other than an authorized person.

  • Page 9: Fluid Quality

    The solar collector may be used for heating of spa or pool water, but levels of free chlorine must not exceed 5 ppm. Otherwise, the copper header could corrode. NOTE: HTP DOES NOT WARRANT THE SOLAR COLLECTOR AGAINST CORROSION-RELATED DAMAGE.

  • Page 10: Wind Stress

    Please refer to glycol manufacturer’s specifications about the temperature ranges the liquid can withstand. Only food grade propylene glycol, FDA rated as GRAS, should be used. NOTE: HTP DOES NOT WARRANT THE SOLAR COLLECTOR AGAINST FREEZE-RELATED DAMAGE. H. WIND STRESS When installing the collector, please consider the issue of wind resistance and the resultant stress on attachment points.

  • Page 11: Hail Resistance

    If damage is sufficient to prevent the product’s use, it may be prudent to not accept all or part of the shipment and immediately alert your supplier. NOTE: HTP DOES NOT WARRANT THE COLLECTOR AGAINST FAILURE AS A RESULT OF DAMAGE INCURRED DURING TRANSPORT OR INSTALLATION.

    H. COLLECTOR ANGLE, PLANE, AND DIRECTION 1. COLLECTOR DIRECTION The collector should face the equator. In the northern hemisphere, this is due south, and in the southern hemisphere, due north. Facing the collector in the correct direction and angle is important to ensure optimal heat output.

    M. PIPE SIZING AND CONNECTIONS HTP solar collectors are provided as standard with 1” copper pipe ports. For domestic heating applications with 1 or 2 collectors, nominal ½” piping is suitable. For applications using 2 - 4 solar collectors in series, it is advised to use nominal ¾”...

    P. MOUNTING FRAME Three mounting choices are available for HTP solar collectors: Tilt mounts, flush mounts, or rack mounts (see Part 4). Feet are supplied to fasten the panel securely to the roof. It is important that frame attachment points and externally supplied fasteners are of suitable structural strength and corrosion resistance.

  • Page 17: Rack Mount (Htp Part # Fp-Rm)

    3. RACK MOUNT (HTP Part # FP-RM) Rack mounts are used to attach collectors to a metal frame (such as Uni-Strut). These mounts can also be used to attach collectors directly to the roof. However, this is unadvisable, as rack mounts install close to the roof surface and allow collectors to collect leaves, snow, and other debris.

  • Page 18: Front Mounts

    2. FRONT MOUNTS Fully loosen the tilt hinge set screws. Once loosened, the tilt hinge will engage into the Quick Lock frame rail. See Figure 5. Slide the flush mount to the desired location along the bottom side of the collector that will meet the roof. Tighten the screw to keep hinge from sliding.

ROOF ATTACHMENT In order to meet strength requirements in areas with winds up to 130 mph / 208 kmh and category “D” exposure, collectors should be mounted into roof studs using lag threaded bolts or J bolts.

  • Page 22: Wall Mounting

    Always consider the weight of the collector and the structural integrity of the wall before installation. HTP requires that installations be inspected and approved by authorized building inspectors and comply with local and state codes BEFORE commissioning the system.

  • Page 23: Part 6 - Plumbing Connections

    PART 6 – PLUMBING CONNECTIONS A. TEMPERATURE SENSOR INSERTION The temperature sensor well must be located near the hot out port. If the collector is designed without a sensor well, use a stainless steel clamp to clamp the sensor onto the hot out port directly to the copper pipe exiting the collector.

  • Page 24: Pressure Open Loop

    2. PRESSURE OPEN LOOP Run the pump at the highest speed setting, forcing air out of the collector and back into the tank. If an auto-air vent is installed on the outlet of the collector, air will automatically eliminate from the solar line. If using a manual air vent, open it until all air is eliminated.

  • Page 25: Pump Selection

    G. PUMP SELECTION When selecting a pump, there are two basic solar designs to consider: pressure glycol and closed loop drain back. In pressure glycol systems, two factors determine pipe size. These are: • Flow rate in gpm (gallons per minute) •...

  • Page 26: Part 7 - System Piping Diagrams

    Incorrect pump size will reduce or fail to deliver solar contribution. To further increase solar production, use a variable speed solar pump controller (HTP part # 8600-047). PART 7 – SYSTEM PIPING DIAGRAMS Figure 23 –...

  • Page 29: Cleaning

    A. CLEANING Regular rain should keep the collectors clean. However, if the collectors are particularly dirty, wash with a soft cloth and warm, soapy water or glass cleaning solution, ONLY if the collector is located in a position which DOES NOT require climbing onto the roof or use of a step ladder. If the collectors are not easily and safely accessible, high pressure water spray is also effective.

    PART 10 – INSTALLATION CHECKLIST The following list is a guide only. Specific items will depend on the nature of the installation. 1 COLLECTOR FACES AS CLOSE AS POSSIBLE TO DUE NORTH/SOUTH. 2 COLLECTOR IS NOT SIGNIFICANTLY SHADED THROUGHOUT THE DAY. 3 COLLECTOR IS NOT LIKELY TO BE STRUCK BY FALLING OBJECTS SUCH AS BRANCHES OR FALLING FRUIT.
