Where the SunSiphon serves as the primary water
heater a thermometer must be placed in a clearly
visible and accessible location in the garage or
laundry/service room. The thermometer must be
placed before the thermostatic mixing valve (see
No. 16, figures 20 & 21). If the SunSiphon preheats
a gas or electric supplemental water heater a line
thermometer must be installed on the hot return line
from the SunSiphon before the supplemental water
heater. The thermometer provides a simple means
of checking system performance.
A high quality thermostatic mixing valve is a
required component in all OG-300 certified systems
and should be plumbed in line with brass union
connections for ease of future repair or replacement
(COMPONENT #17, FIGURES 20 & 21). The mix-
ing valve shall be standard ASSE 1017 approved.
The specified mixing valve shall be the Heatguard
Model HX110D, Watts LFL1170-M2-US or equal
and should have an operating range between 95°F
and 120°F. The mixing valve shall be adjusted to no
more than 122°F delivered water temperature.
WARNING: SCALDING CAN OCCUR
WITHIN FIVE SECONDS WHEN WATER
TEMPERATURES APPROACH 140º F. THE
MIXING VALVE SHOULD bE ADJUSTED bY
YOUR CONTRACTOR TO PROVIDE WATER
TO YOUR FIXTURES AT NO MORE THAN
122º F.
4.5 Fill the Storage Tank
Open the isolation ball valve (see No. 18, figures 20
& 21), and begin filling the solar storage tank.
THE SOLAR STORAGE TANK MUST
bE COMPLETELY FILLED WITH WATER
AND UNDER CITY MAINS PRESSURE
bEFORE THE HEAT EXCHANGE JACKET
AND COLLECTOR LOOP ARE CHARGED
WITH HTF. NEVER CHARGE THE HEAT
EXCHANGE JACKET bEFORE THE SOLAR
TANK IS FILLED AND PRESSURIZED.
FAILURE TO FOLLOW THE PROCEDURES
OUTLINED IN SECTION 4.5 IN THE PROPER
SEQUENCE MAY CAUSE SEVERE DAMAGE
TO THE HEAT EXCHANGE JACKET.
In new home construction do not fill the solar stor-
age tank or charge the heat exchange jacket with
HTF until the home is occupied and the system is
ready for use.
4.6 Clean the Collector Loop Piping and Check for
Leaks
Piping in new solar installations can be covered
with dirt, grease, solder flux or other impurities that
over time can affect the quality of the glycol HTF.
A thorough cleaning is required before charging the
system with glycol. A simple solution of 1 to 2 per-
cent trisodium phosphate in water will eliminate the
solder flux from the collector piping. Introduce the
proper volume of solution in accordance with Table
4 and the heat exchanger fill instructions found in
section 4.7.3 below.
Once the solar storage tank is completely filled with
water and pressurized, thoroughly flush the collector
and heat exchanger piping with water.
• Attach a garden hose to the ball hose bib
and turn on the garden hose.
• Open the ball hose bib handle and let water
run through the collector piping and heat exchange
jacket for a minute or two. The water will flow out
of the vent plug socket.
• Close the ball hose bib while the heat
exchange jacket and collector loop piping are still
filled with water.
• Turn off the hose and detach it from the ball
hose bib. Check the piping for any obvious leaks.
• Open the ball hose bib and drain the water
from the collectors and heat exchange jacket.
Once the solar collectors and storage tank are
plumbed and the piping has been cleaned and
examined for leaks, proceed to charge the collector
loop with a mixture of heat transfer fluid (HTF) and
distilled or deionized water. Do not use regular tap
water.
4.7 Fill the Collector Loop with Heat Transfer
Fluid
Proceed as follows:
4.7.1 Cover the solar collectors with an opaque
material such as cardboard until the heat exchange
jacket has been completely charged.
4.7.2 Remove the ¾” dust cap vent socket on the
solar storage tank when filling the collector loop and
heat exchanger. This allows air to purge as the col-
