TECHNICAL SPECIFICATION
ADDITIONAL APPLICATIONS
FOR TOILETS: drain tank and bowl then add 1 quart or more of undiluted
Cryo-Tek Original to each toilet bowl to percent freeze-up.
FOR BOATS AND TRAILERS: For boats and trailers with pressurized hot
water systems, see TABLE III. For these systems, disconnect water tank and
join inlet and outlet to form a bypass. Drain water tank thoroughly and add
Cryo-Tek Original (diluted to desired freeze protection, see Table III)
to displace.

CAUTION REGARDING COMPETITIVE PRODUCTS:
Hercules Cryo-Tek products are formulated using virgin propylene glycol and
high purity Triple Protection Additives for assurance of materials compatibility
and non-toxicity characteristics. Dilution or mixing of Cryo-Tek products with
other manufacturers’ products may compromise these critical requirements
and is not recommended.

DIRECTIONS FOR USE
1. 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 efficiency and wears the system prematurely. New systems need to be free
of flux, solder residue, grease and any foreign particles. Most boiler manufacturers recommend cleaning new systems with a solution of Tri-Sodium
Phosphate (TSP), or Oatey approved System Cleaner (Follow instructions on container). Existing systems need to be flushed 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 (except aluminum
systems, check with boiler manufacturer). All systems should be checked for leaks prior to installation of any Cryo-Tek product.
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.
WARNINGS OR CAUTIONS
• Read all cautions and directions carefully before using this product.
• Not for use in steam systems.
• Not for use with CPVC pipe and fittings.
• Use Hercules Boiler Liquid to stop leaks on system containing
Cryo-Tek products.
• Use Oatey approved System Cleaner to clean system prior to using
Cryo-Tek (see installations instructions).
• Do not use in internal combustion engines as a coolant.
• Do not use in water softeners. Disconnect all water softeners from
system or provide back flow protection to prevent contamination of
brine or resin bed.
• Cryo-Tek products are not recommended:
1. For use in systems containing galvanized components.
2. For open solar systems and systems where operating stagnation
temperatures are regularly over 300°F/150°C.
3. For systems with concentrating solar collectors or evacuated tube
solar collectors.
4. In systems containing aluminum. (Please check with equipment
manufacturer of system to determine compatibility with
this product).
