AURORA SOLAR COLLECTOR - tor is where the sun’s energy is harvested and is typically mounted on the top of your roof. Water is pumped through exceed temperature and pressure design ranges for the Simple Drainback Systems.
Page 5: Installation Instructions
Safety SYSTEM SAFETY DEVICES Your system contains many protection devices. A pressure-temperature relief valve on the backup hot water tank ensures that the water in the Tank does not over heat or over pressurize. The Simple Drainback Tank enables all the water in the system from freezing even during power outage.

Page 8 Installation Instructions COLLECTOR MOUNTING There are two basic roof-mounting methods: Flush Mount Installation - Parallel to the roof line, as illustrated below. Mounting Bracket Solar Collector Roof Truss Mounting Bracket Figure #1 Flush Mount Installations are recommended when the roof’s slope conforms to the orientation requirements as stated previously.
Page 9 Installation Instructions COLLECTOR MOUNTING (CONT’D) Verify a secure connection to the trusses. If lagging directly into the roof trusses is not possible, secure a 2’ x 4’ wood beam perpendicular to the trusses, inside the attic, and anchor the bolts to this member. Again, verify a secure connection into the new member.
Page 10 Installation Instructions COLLECTOR MOUNTING 1. Use the Angle Mounting kit SLAR-TM (Picture 5). Connect the U-channels to the roof just like in the Flush Mounting method. Assemble the mounting clips to both U-channels utilizing the provided bolts (Picture 6). Picture 5 Picture 6 2.

Installation Instructions COLLECTOR MOUNTING ONT’D 5. Lift the collector’s top with the assembled rod kits and anchor the U-channels to the roof, ensuring the proper angle to the collectors (Picture 10). Picture 10 sembly is not reduced. PLUMBING Penetrations of the building through which piping or wiring is passed shall not reduce or impair the function of the enclo- sure.
Page 12 Installation Instructions PLUMBING (CONT’D) Hard copper connections to the city cold water supply line and the home hot water feed lines are recommended. The gas- kets in standard water heater ex hose connectors can become brittle and compressed over time and begin leaking on the water heater.
Page 13: Checking For Leaks In The Solar Loop
Installation Instructions PLUMBING (CONT’D) CHECKING FOR LEAKS IN THE SOLAR LOOP Checking for leaks in the solar loop utilizes ths same proce- dures used by plumbers when checking for leaks in new construction. The solar loop must be isolated. Using a compressor, pressurize the solar loop to 25 lbs.
Page 14: Thermometers
Installation Instructions The T1 temperature sensor (black wire) should be securely fastened to the manifold outlet of the collector. A stainless steel screw clamp should be used (Figure #1). Sensor wire can be extended up to 165 feet with AWG #18 wire and up to 330 feet with AWG #14 wire. The collector wires should be fastened to the T1 wire location on the controller and secured with the wire strain reliever.
Page 15: System Start-Up
Installation Instructions SYSTEM START-UP Throughout the installation procedures outlined above, emphasis has been placed on the correct procedures for plumb- ing and wiring the components and checking for plumbing leaks. Having completed these tasks it is time to start up your Simple Drainback solar water heating system.
Page 16: System Operation
Installation Instructions SYSTEM OPERATION (TWO TANK CONFIGURATION) solar water heating system can (1) provide 100% solar operation during good weather, or (2) serve as a pre-heater to your electric or gas backup water heater adding solar energy when and as available, or (3) 100% on utility power during inclement weather.

SOLAR HEAT EXCHANGE SIMPLE DRAINBACK TANK All Simple Drainback systems come with an 80 to 120 gallon Simple Drainback Tank. These tanks are a tank within a tank.
Page 24: Valves In The System
System Components VALVES IN THE SYSTEM COLD WATER INLET VALVE – This valve is a conventional gate valve located on the cold inlet to the solar storage tank that allows you to shut o all the water in the tank. This is an EMERGENCY SHUTOFF VALVE — in the event that there happens to be a leak in the tank or the associated hot water plumbing in your house.
Page 25: Automatic Differential Control
System Components AUTOMATIC DIFFERENTIAL CONTROL SHEM32 FOR TWO TANK CONFIGURATIONS – Power to the Solar Pump is controlled by an Automatic Di erential Control that has two temperature sensors. One sensor is located on the outlet of the Solar Collector and the other sensor is located on the Simple Drainback Tank.
Page 26: Owner's Information
Owner’s Information OPERATING SUGGESTIONS A properly designed solar hot water system provides solar energy for approximately 70-90% of your yearly hot water needs. Listed below are some suggestions that you can follow to maximize the bene ts of your solar hot water system. 1.
Page 27: Routine Maintenance
Owner’s Information ROUTINE MAINENANCE There is very little maintenance that your solar system requires. Collectors will usually wash themselves in the rain. If rainfall DO NOT USE ACID OR HARD BRISTLE BRUSHES AND DO NOT POUR COLD WATER ON HOT GLASS. OPERATING PROCEDURES START-UP PROCEDURES The Simple Drainback Installation Instructions give detailed instructions for plumb-...
Page 28: Indicators Of Proper Operation
Owner’s Information OPERATING PROCEDURES (CONT’D) If your Simple Drainback Tank should develop a leak, the whole solar system can be isolated from your home’s water supply by positioning the solar bypass valves as described in diagram #2 on page 5. If your conventional backup hot water tank should develop a leak, the cold-water inlet valve (#13) can be closed.
Page 29: Solar Bypass
Owner’s Information (CONT’D) INDICATORS OF PROPER OPERATION a long cold winter spell, tank temperature (T2) can be as low as the tap water entering the tank (40-55° F). During the summer, T2 could reach 180° F. Collector temperatures (T1) can similarly vary. During T1 can reach 235°...
Page 30: Freeze Protection
Owner’s Information FREEZE PROTECTION Your system is designed to be protected against freeze damage to temperatures as low as -10º F as long as temperatures where the Simple Drainback Tank is located remain above freezing. Freeze tolerance limits are based upon an assumed set of environmental conditions.
