5. CHARGING THE SYSTEM
System should be completely empty with burner and pump shut off. All internal valves, including zone valves,
should be open. THE ENTIRE SYSTEM SHOULD BE OPEN TO PREVENT ANY AREA OF IT FROM BEING ISOLATED. First,
add the computed amount of Cryo-Tek product, second add water if necessary. The system can be filled using
one of the following two alternatives. The main objective is to dill the system with little or no air trapped in it.
A. After providing for an air exit, pump solution into boiler through the boiler drain valve using a small pump.
B. Pour solution through a removed air vent at the HIGHEST point in the system.
6. PURGE THE AIR IN SYSTEM
Since air (which includes oxygen) trapped in a system not only results inefficiencies in the operation of the
system (wasted energy and excessive noise), it can also cause corrosion. To prevent this, the system, once filled,
needs to be purged of all sir.
7. TEST THE SYSTEM
Once installed and fully operational, use Hercules Refractometer with Refractometer Reading Adjustment Chart
and pH Meter or Cryo-Tek Test Strips to test fluid to assure proper freeze and corrosion protection. Note:
Automotive coolant tester will not work with Cryo-Tek or other propylene glycol anti-freeze mixtures.
8. MAINTENANCE
Systems with Cryo-Tek products installed should be tested annually for product concentration and inhibitor
levels using Hercules Refractometer with Refractometer Reading Adjustment Chart and pH Meter or Cryo-Tek
Test Strips. If Cryo-Tek product concentration levels are low, add Cryo-Tek products using the following formula:
TOTAL SYSTEM CAPACITY (gal) X (% Cryo-Tek - % Cryo-Tek in system) = Number of gallons of Cryo-Tek product to be added
(%Cryo-Tek used - % Cryo-Tek in system)
If the corrosion inhibitor tests low, add one 8 oz. container of Cryo-Tek inhibitor for every 20 gallons of fluid capacity of
the system. If the total system capacity is less than 20 gallons, add one 8 oz. container of Cryo-Tek Inhibitor. If after
inhibitor addition and thorough system mixing the corrosion inhibitor still tests low, add another 8 oz. container of Cryo-
Tek inhibitor for every 20 gallons of system capacity. If after this addition the inhibitor still tests low, the system should be
drained, cleaned, and recharged with fresh Cryo-Tek.
