Clean the System

It is recommended that any system, whether new or existing, be

thoroughly cleaned prior to being charged with Cryo-Tek products.

Any system contaminated with dirt and other materials reduces

efciency and wears the system prematurely. New systems need to

be free of ux, solder residue, grease and any foreign particles.

Most boiler manufacturers recommend cleaning new systems with a solution of Tri-Sodium Phosphate

(TSP), or Hercules Boiler and Heating System Cleaner (follow instructions on container). Existing systems

need to be ushed and cleaned to eliminate any build-up of rust, scale, lime and other non-organic

matter.

These systems should be cleaned with an inhibited hydrochloric acid such as Hercules Sizzle (except

aluminum systems, check with boiler manufacturer). All systems should be checked for leaks prior to

installation of any Cryo-Tek product.

Measure the Total Capacity of the System

Direct Method

A. Fill system completely, making sure all components of system are full.

B. Shut system down and let pressure drop to a safe level.

C. Drain out uid into a 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.

A well-maintained hydronic heating system provides reliable performance

even during the harshest winters. Heating maintenance professionals know

that top quality materials are critical to achieving superior performance.

That is why contractors depend on Hercules Maintenance and Stop-Leak

Products. They are formulated for high performance and developed with

both the user and the environment in mind.

INSTRUCTION GUIDE HERCULES CRYO-TEK 5 Charge the System The system should be completely empty with the 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. B.

INSTRUCTION GUIDE HERCULES CRYO-TEK If the corrosion inhibitor tests low, add one 8 oz. container of Cryo-Tek inhibitor for every 20 gallons of system fluid capacity. 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.
