Sunward TM Solar Hot Water System 85

1A How It Works

The Sunward Solar Hot Water System is extremely effective at absorbing energy from the sun and converting it to hot water . Here is how it works: 1 . The Photovoltaic Module produces electricity and turns on the Sunward Solar Pump

2 . The Pump circulates Heat Transfer Fluid (AWWA Glycol Class II) through the Solar Collector .

NOTE: The Glycol is a 40/60% by volume mixture of Propylene Glycol USP and Distilled Water that provides freeze protection to -60°F (-51°C). Never use anything other than Sunward Glycol Heat Transfer Fluid .

3 . Heat is absorbed by the Glycol in the Solar Collector .

4 . The heated Glycol is then pumped to the Sunward Heat Exchanger where the heat is transferred to the potable water, which then circulates naturally to the top of the Sunward Solar Storage Tank .

5 . The Solar heated water is stored in the Solar Storage Tank until you draw water from your existing water heater .

6 . As hot water is drawn from the existing water heater, it is replaced with solar heated water .

For most of the year, the system will create 100% of your hot water . If necessary, your existing water heater will increase the temperature of the solar heated water . However, the energy required to heat water is significantly less when it is pre-heated with the solar heated water .

Note: To determine how much hot water the system is producing, open a hot water tap somewhere in the house. This will push water out of the tank and pass the thermometers. Always open a hot water tap to get an accurate reading

2A: Back Flushing the System:

To ensure optimum performance of the Heat Exchanger and the Solar Storage Tank, we recommend that you back flush the system at least once every six (6) months .

1. Close the Ball Valve at the bottom of the Solar Storage Tank (Figure 2) . Connect a hose to the Drain Bib and drain approximately 10 gallons of water .

2. Close the Drain Valve and re-open the Ball Valve .

3. Flush the tank using the other Drain Valve .

To determine if your system is producing hot water, perform the following simple test .

Read the Temperature Gauges located on the front of the Solar Manifold (Figure 2) . At the end of a bright sunny day, open a hot water faucet and observe the Temperature Gauges . The temperature of the water leaving the Solar Storage Tank should be higher than the temperature of the supply water going into the Tank .

Note: Check the Glycol for ph and contamination at least once a year. Using the wooden dowel, check the fluid with the system operating and make sure it is clear with a ph of between 6-7. If the fluid is black (carbon particles) and/or the ph is not between 6-7 , drain and refill the Glycol.

Be sure to keep a service log indicating when you back flushed the system. Failure to do so will render the warranty null and void.

! WARNING tank water could potentially be very hot.


2B: Check for Glycol loss in the Collector loop at least once a year.

Locate the Fill Tube at the side of the Heat Exchanger and remove the Brass Cap (Figure 3 ) .

Using the wooden dowel provided, check the fluid level in the reservoir . This level should be 8”-12” from the bottom of the dowel while the system is operating . If the level is low, follow the filling instructions on page 8 .

2C: Draining the Glycol

1. Turn the system OFF by removing the Photovoltaic Module Plug . The Pump Motor will then stop .

2. Disconnect the Micro-Tubing from the Heat Exchanger and allow the fluid in the Micro-Tubing to drain into a container . Leave the lines disconnected .

Note: To drain the Glycol from the Heat Exchanger, you will have to wait until there is enough sunlight to operate the system.

3. With a container under the Outlet of the Pump, turn ON the Heat Exchanger by reconnecting the Photovoltaic Module Plug . Keep the Pump running until no fluid comes from the Pump .

4. Reconnect the Micro-Tubing to the Heat Exchanger . The system is now drained and ready for refilling .

2E: Refilling the System with fresh Glycol

Note: The system will require approximately 1 gallon of Glycol (plus 1.5 quarts of additional Glycol per every 100 feet of Micro-Tubing to the Solar Collectors).

1. Remove the Pressure Relief Valve and Brass Cap on the Fill Tube on the Heat Exchanger (Figure 5) Place a small container under the Vent Tube . Slowly fill the Heat Exchanger (using a small funnel) with fresh Glycol until the fluid comes out the Vent Tube .

2. Turn the system ON by flipping the switch on the Linear Control Module (Figure 5 ) . The Pump Motor will then start .

Note: A reminder, the Heat Transfer Fluid has to be a 40/60 mixture by volume of Propylene Glycol USP and Distilled water. Never use anything other than SUNWARD Glycol

3. After the Pump has been running for a few minutes, the air bubbling noise should stop .

4 . Reinstall the Brass Cap on the Fill Tube and the Pressure Relief Valve .

5. Check the system for leaks at all Micro-Tube connections . If a leak is noted, tighten the nut another 1/4 turn .
