Bleeding
NOTE: Should it be discovered that a loss of pressure has occurred, be sure to check
all plumbing system connections for leaks (air leaks, in the form of bubbles, can
be visually detected by applying a solution of soapy water to each plumbing
system connection).
E. If applicable, repair all plumbing leaks.
1. Remove the Aqua-Hot’s Fill/Radiator Cap and completely fill the Heat Tank by
pouring in 16 gallons of a 50/50 antifreeze and water heating solution.
NOTE: As antifreeze itself does not possess acceptable heat transfer characteristics,
water is added to the antifreeze due to its excellent heat conduction properties.
In order to provide the best freeze protection, boil-over protection, and
anti-corrosion and rust protection, a 50/50 mixture ratio of propylene glycol
antifreeze and water is recommended to provide the best performance
combination of the aforementioned functions. If excess propylene glycol exists
within an antifreeze and water heating solution, the water’s heat absorption
properties are compromised, which could ultimately inhibit the Aqua-Hot
Hydronic Heating System from providing adequate domestic hot water and
interior heating. Also, if there is a shortage of antifreeze, the Aqua-Hot Hydronic
Heating System is not as well protected in terms of freeze protection and
anti-rust/anti-corrosion protection.
2. Replace the Aqua-Hot’s Fill/Radiator Cap, but do not tighten completely.
NOTE: The Fill Radiator Cap should remain loose during the Bleeding and Filling
Procedure in order to allow air to escape from the top portion of the Aqua-Hot’s
Heat Tank.
3. To activate one of the Aqua-Hot’s Circulation Pumps, switch ON any Interior Zone
Thermostat to its maximum temperature setting. Allow the Circulation Pump to
operate for approximately one minute, then switch it OFF . This will fill the Heating
System’s plumbing lines.
4. Again, remove the Aqua-Hot’s Fill/Radiator Cap and completely fill the Heat Tank
with additional antifreeze and water heating solution.
5. Repeat steps 3 and 4 for all Heating Loops until all air has been completely bled
from the entire Hydronic Heating System.
6. Once all air has been bled from the Hydronic Heating System and the Aqua-Hot’s
Heat Tank has been completely filled, completely tighten the Fill/Radiator Cap.
3.27 Bleeding the Domestic Water System
NOTE: Verify that the Domestic Water Tank is full prior to bleeding the Fresh Water
System.
1. Ensure that the Domestic Water Pump has 12 Volt-DC power, then activate the
Domestic Water Pump by opening all water faucets separately.
2. Once the Domestic Water System is completely bled, check for leaks.
