페이지 인쇄Do not use uninhibited glycols or antifreeze solutions intended for automotive use.
The glycol solution should be premixed in a tank before being added to the system. This provides a uniform mixing
and eliminates the concern of water pockets that could freeze and cause system damage.
If the solution is to be mixed on site, be sure to use good quality dilution water and follow the manufacturer's
directions. Mix the solution thoroughly and test the concentration before it is introduced to the system. Use a
refractometer specifically designed for heat transfer solutions to determine the glycol concentration.
When calculating the total volume of solution required, see table "Fluid volumes" in chapter "System charging" on
the previous page, for the internal volume of the thermal storage coils.
To fill the system, open all system flow control valves and the air vent(s) at the system high point(s) to allow the
glycol solution to flow freely throughout the system. Then, pump the premixed solution into the system. When the
charging is almost complete, isolate the charging tank or tank truck from the glycol loop and turn on the system
circulating pump to ensure the solution is circulated throughout the loop. Operate the pump for 24 hours and then
check the system pressure and glycol concentration.
(1) Standard in- and outlet connections are threaded. To avoid damage to insulation and tank lining,
welding at the tank connections is not recommended.
(2) Freeze protection must be obtained by the use of ethylene or propylene glycol or other anti-freeze
solutions in appropriate concentrations.
(3) The systems lowest operating temperature should be at least 3°C to 4°C above the anti-freeze solution
freeze point.
(4) Ethylene glycol solutions are not compatible with galvanized steel parts. Therefore glycol piping should
only be galvanized at the outside.
(5) The Model TSU-237M and TSU-L184M have two ND15 vent connections (see figure below "Air vents
on TSU-237M and TSU-L184M") that must be bled during the charging process. The installing contractor is
responsible for providing the vent valves and plugs

Purge requirements
The installer of BAC equipment must ensure proper system purging of air prior to operation. Entrained air can
obstruct the proper flow of glycol solution, resulting in higher operating pressures than design and reduced thermal
storage capacity.
