2. MEASURE THE TOTAL CAPACITY OF THE SYSTEM using one of the following methods:
DIRECT METHOD
A. Fill system completely, making sure all components of system are full.
B. Shut system down, let pressure drop to a safe level.
C. Drain out fluid into suitable container and record the number of gallons removed. This is TOTAL SYSTEM FLUID CAPACITY.
ESTIMATION METHOD
A. Determine system pipe sizes and amount of linear footage for each size. Using Table I, calculate the volume of the
system piping.
B. Add this number to the gallon capacity of the boiler or equipment in the system to determine the
TOTAL SYSTEM FLUID CAPACITY.
TABLE I (Note: 1 US Gallon = 3.785 Liters)
3. SELECT DESIRED TEMPERATURE COVERAGE
Using Table II determine protection level desired and match it to the appropriate cryo-tek product concentration.
TABLE II
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 fill 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 in 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.

Pumpable down to protection levels are estimated and are dependent on system and equipment. Attempting to circulate fluid below freeze point may overload and/or
cause pump failure.
