and/or cause pump failure
4. DETERMINE AMOUNT OF CRYO-TEK PRODUCT REQUIRED IN SYSTEM
Determine the amount of Cryo-Tek product needed in system by
multiplying total system capacity in gallons by the concentration
factor of Cryo-Tek product (first column in each chart above).
Total System Capacity (gal) X Concentration Factor of Cryo-Tek
Product (%) = Amount of Cryo-Tek Product to be used (gal)
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 air.
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:
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.
