HEAT TRANSFER FLUID SPECIFICATION AND SYSTEM NOTES

7. NOTES

7.0. General Dyn-O-Flo HD Notes

Dyn-O-Flo HD is a 100% concentrate inhibited propylene glycol and is recommended 
for use in applications where low acute oral toxicity is important or where incidental 
contact with drinking water is possible.  Extra strength corrosion inhibitors in the HD fluid 
are formulated for high temperature use, resulting in reduced maintenance and longer 
inhibitor life in most applications.  Freeze tolerances are based on a set of acceptable 
limits.

7.0.0. Use Directions

 

Do not use full strength.

• 

 

Recommended concentration is 40 – 60%. 

• 

 

Dilute with good quality soft water.  If the tap water has more than 25 ppm of 

• 

chloride or sulfate ions, or more than 50 ppm of calcium or magnesium, use 
mountain spring water.

 

Do not use zinc or galvanized components in contact with the fluid. 

• 

 

System preparation:  Flush thoroughly with water (use 1 – 2% TSP) and 

• 

circulate without adding heat, before introducing the operating fluid. 

 

Fluid Introduction: Please see the Helio-Pak systems Manuals for filling, 

• 

venting and priming. 

 

Maintenance: The fluid should be checked periodically for pH, which should 

• 

not drop below 8, and reserve alkalinity, which should stay greater than zero 
at all times.  

 

Flush thoroughly before replacing with new mix. 

• 

 

The Dyn-O-Flo HD has an operating temperature range of -50 – 325 ˚F.

7.0.3. First Aid

While essentially non-irritating, absorbing or toxic, Dyn-O-Flo HD heat transfer fluid should 
be kept away from children and be treated with care.  In case of physical contact, follow 
these directions:

 

• 

Eyes

   

Flush with plenty of water

 

• 

Skin

   

Wash off with flowing water

 

• 

Ingestion:

   

Induce vomiting and consult a physician

 

• 

Inhalation

:  Remove to fresh air, consult physician.

Notice to Physician: No specific antidote.  Supportive care based on judgment of 
physician.

7.0.4. Handling

 

• 

Exposure Guidelines:

  Propylene glycol: AIHA WEEL is 50 ppm total, 10 mg 

/ m

3

 aerosol only.

 

• 

Ventilation

:  

Good general ventilation should be sufficient for most 

conditions.

 

• 

Respiratory Protection:

 No respiratory protection should be needed.

 

• 

Skin Protection

 

For brief contact, no precautions other 

than cleaning of body and covering.  Use impervious gloves when prolonged 

   

 

   

 

or frequently repeated contact occurs.

 

• 

Eye Protection

 

Use safety glasses.

 

• 

Spills

   

 

Cover with absorbent material, soak up 

and seep into bag.

 

• 

Disposal

:    

Discharge into sanitary sewers only with the explicit 

pre-approval of the local waste water facility.  Any disposal 

  

 

   

 

practice must be in compliance with 

federal, state, provincial and local laws and regulations.  Check with the 
 

 

 

 

  appropriate 

agencies.

7.0.5. Maintenance

The glycol / water mix should be tested periodically for freeze protection and pH.  Empty 
the system and flush thoroughly before replacing with a fresh mix when the pH drops 
below 8, or reserve alkalinity approaches zero.

7.0.6. System Fluid Information

Always use copper tubing for collector supply and return connections. 

 

Black iron pipe can also be used, with proper dielectrics.  Never use 
galvanized pipe or plastic based products, such as PEX.

Use only Dyn-O-Flo HD heat transfer fluid with good quality water mixture: 
min 40% HD mixture, max 60% HD mixture.  Do not use distilled water.  
Good quality water: chlorides and sulfates must be less than 25 ppm; 
calcium and magnesium must be less than 50 ppm (as calcium carbonate, 
with hardness less than 100 ppm).  If unsure, use bottled mountain spring 
water.

Rinse system with 1 – 2% mixture of trisodium phosphate and water. 

 

Remove the expansion tank for testing only, and pressure test system with 
water before filling.

Maintain minimum operating pressure of 30psig when system is cold to 
avoid pump cavitation.  If using an air vent during filling, ensure it is closed 
during system operation.

7.0.7. Safety Precautions

Follow all local codes and regulations.  Work should only be performed on 
the HPAK and system when it is disconnected from the power supply.

When creating and repairing roof penetrations, ensure final seal 
disallows any unwanted animal or creature intrusion, and the integrity 
of the structure is not compromised.  Penetrations through fire-rated 
assemblies must not reduce fire resistance capacity below code.  Ensure 
building materials adjacent to solar components are not exposed to 
elevated temperatures.

7.0.8. Components

Always install a tempering valve, or rated anti-scald valve, after the 
solar storage tank.  Route the pressure relief port on the HPAK to avoid 
accidental scalding in case of release.

Place the HPAK and tank in a non-freezing environment.

Solder suitable for 400°F and 150 psig must be used: 96/4 Tin / Silver is 
recommended.

7.0.9. Description Of Product and Operation

The HPAK is a fully automatic solar energy heat transfer appliance.  The 
controller senses the collector and storage temperatures and powers both 
circulation pumps when the collector has achieved enough temperature 
over the solar storage tank.  See the Delta-T and Delta-T Pro manuals for 
full descriptions of operation and functions.

7.0.10. Commissioning

After the system is filled, it is normal for the initial pressure to drop as air 
comes out of solution.  Repressurize the system to ensure at least 30psig 
when cold.
