Page 4: Monitoring Your System (Please Read Carefully)
When leaving for extended periods in the summer or winter, there is no need to switch your system off. (See Operation and Maintenance, page 34 and Troubleshooting, page 35.) You should check your flow meter and temperature gauge at least once a month. In case of emergency call your installer: ____________________________________ or Sol-Reliant at (503) 866-6437...
Page 5: System Diagram
System Diagram All the components of your system are listed in the diagram below: How It Works Your system is closed loop, which means the solar heating components including the collector, pump, heat exchange coil, and drain back reservoir are part of a closed circuit -– a closed circuit separate from the potable water system.
Page 6: System Components
System Components Collector The Sol-Reliant solar thermal collector uses AET Thermafin absorber plates. These are all- copper absorbers with a selective surfacing called Black Majic, which allows for optimum absorption in sunny or cloudy weather. This special surfacing gives you 96% absorption when...
Page 7 Pump and Control The Sol-Reliant uses a 12-volt DC pump to circulate the heat transfer fluid through the solar collector and heat exchanger. You should expect to see a flow rate of 1-3 gallons per minute at the flow meter, located on the plumbing of the solar storage tank (see below).
Page 8: Tempering Valve
Solar Storage Tank Isolation Valve (Two tank systems only) The Sol-Reliant solar storage tank can be bypassed** (or “isolated”). In the event that your solar storage tank ever has a problem or a leak, the solar storage tank can be isolated while maintaining full hot water service to the house.
Page 9 Heat Transfer Fluid The Sol-Reliant system uses a Class II heat exchange fluid produced by Dowfrost HD, a non- toxic propylene glycol antifreeze, in combination with distilled water, in the solar loop plumbing as a heat transfer fluid.
Page 10 Roof Flashing The Sol-Reliant uses a single stainless steel flashing for both pipes penetrating the roof. With the accompanying rubber boot it allows water-tight penetrations in a single, well-protected location. The Sol-Reliant uses no-caulk flashings for all other flashings, one for each of the standoff brackets that support the collector and another for the electrical weatherhead.
Page 11: Pipe Insulation
R-6 high temperature closed-cell pipe insulation. Reservoir The Sol-Reliant system features a uniquely integrated, hidden reservoir. A copper pipe holds enough heat transfer fluid to keep the pump primed, a custom 2” diameter pipe running the full length of the collector.
Page 12: Collector Installation Instructions - Rooftop Installation
Including the width of the PV module, the collector will occupy a footprint of 15’9” from side to side by 46-1/2” from top to bottom. NOTE: the Sol-Reliant collector must slope no less than 1’4” and no more than 1/2” from the high side of the collector to the low side where the pipes come out of the collector.
Page 13 Step 6, since the collector will then be covering them. STEP 6 (ROOF): With the help of at least one assistant, set the Sol-Reliant collector on the mounting brackets. Measure from the outside edge of the L-bracket to the outside edge of the collector on each side, slide the collector side to side until centered (centered without regard for the PV module.
Page 14 looking “funny”), that is, the two dimensions between L-foot and collector edge are the same distance. STEP 7 (ROOF): Once collector is centered, mark where pipes will go through the roof. Use a Dixon or other crayon to make this mark (yellow tends to be the most visible). Get your eye close to the roof and make a vertical line at the midpoint between the two unions.
Page 17 The “Anti-Siphoning Assembly” consists of brazed fittings configured so that the reduction in pipe size is done in the vertical rather than horizontal plain. This prevents any possibility for thermal siphoning.
Page 19: Solar Tank Installation Instructions
Installing the solar tank & completing the solar loop Your Sol-Reliant system comes with the lower portion of the solar loop pre-plumbed and pressure tested. The pump (with both its manual and high-limit switches) is installed on the tank. The pump is attached to the “supply line” (the pipe in which fluid goes up to the collector). The Flow meter is installed in the line above the pump.
Page 20 The line on the left at the top of the tank is the hot outlet of the solar tank to your back up water heater. The line on the right is the cold inlet from the cold supply to the hose. STEP 3: Place a Tee in the line downstream of the shut off valve.
Page 21: Wiring Pump And Charging The Solar Loop
Keep the pump switched “off” until wiring is complete. The Sol-Reliant system comes with two MC (MultiContact™) Cables on the roof for quick connecting and disconnecting of the solar module. Two more MC cables are wired onto the module before shipping.
Page 22 Having determined the amount of fluid needed to fill the system, place that amount in a clean bucket in ratio to the glycol/water mixture needed. Example, 4 gallons needed to operate the system, 50% glycol mixture for the subject climate, use 2 gallons of glycol and 2 gallons of distilled water.
Page 35: Operation And Maintenance
NOTE: There will be no flow through the flow meter on a sunny day if the system has reach a its high limit temperature. When leaving home for extended periods it is not necessary to turn off your Sol-Reliant system. The system will shut itself off automatically once high temperature limits are reached.

STEP 5: Remove the hex head screws that hold the solar thermal collector to the mounting brackets. The solar thermal and photovoltaic collector should now be free to lift off and place to the side so that the area under the collector can be re-roofed. Once the new roof is in, the Sol-Reliant...
Page 37 Take the removal steps in reverse order to reinstall the Sol-Reliant. STEP 1: Place collector onto the mounting brackets. Screw in tech screws in the exact location from which they came. STEP 2: Make electrical connections.

(Single Tank Systems Only) WH40 ELECTRIC WATER HEATER TIME SWITCH DOUBLE POLE, 10,000 WATTS (40 AMP) MAX., 250 VOLT - 60 HZ. This Time Switch will repeat a preset schedule daily, except when the EXTERNAL MANUAL LEVER is used. This manual lever permits the user to turn the water heater ON and OFF ahead of the schedule.
