CHAPTER 10 - START-UP PREPARATION
10.1.7 Check and Test Antifreeze
For boiler systems containing antifreeze solutions, fol-
low the antifreeze manufacturer’s instructions in verify-
ing the inhibitor level and to ensure the uid character-
istics are within specication requirements.
Due to the degradation of inhibitors over time, antifreeze
uids must be periodically replaced. Refer to the manu-
facturer of the antifreeze for additional instructions.
10.1.8 Use of Antifreeze in the Boiler System
NEVER use automotive or ethylene glycol an-
tifreeze or undiluted antifreeze in the system
as freeze protection. This can result in sub-
stantial property damage, serious injury, or
death.
Determine the antifreeze uid quantity using the sys-
tem water volume and following the antifreeze manu-
facturer instructions.
The water volume of the INSTINCT is approximately:
- 2 gallons [8 L] for INSTINCT Solo 110
- 3 gallons [12 L] for INSTINCT Solo/Combi 155 and
INSTINCT Solo 199
- 4 gallons [15 L] for INSTINCT Combi 199.
Remember to include the volume of the expansion tank.
Check with local code requirements for the installation
of backow preventers or actual disconnection of the
boiler’s cold water ll or make up water supply line.
Massachusetts Code requires the installation of
a backflow preventer if antifreeze is used.
Ensure the concentration of antifreeze to water does
not exceed a 50/50 ratio.
System fluid including additives, must be prac-
tically non-toxic, having a toxicity rating or
Class of 1, as listed in Clinical Toxicology of
Commercial Products.
WARNING
NOTICE
NOTICE
HOT WATER CAN SCALD!
• Water temperatures over 125ºF can cause
severe burns instantly, or death from scalds.
• Feel water before bathing or showering.
• Consumer Product Safety Commission
and some states recommend tempera-
tures settings of 130ºF or less. Setting
thermostat higher than 130ºF will in-
crease risk of scald injury and cause se-
vere personal injury or death.
• Water heated to a temperature suitable
for clothes washing, dish washing and
other sanitizing needs will scald and
cause permanent injury.
• Children and elderly, infirm, or physical-
ly handicapped persons are more likely
to be injured by hot water. Never leave
them unattended in or near a bathtub. If
anyone using hot water in the building
fits this description, or if state laws or lo-
cal codes require certain water tempera-
tures at hot water faucets, take special
precautions.
Ū Install the factory supplied automat-
ic mixing valve at water heater and/
or install a point of use mixing valve
at each hot water faucet, bath and
shower outlet. Selection and instal-
lation of point of use mixing valves
must comply with valve manufac-
turer’s recommendation and instruc-
tions.
Ū Use the lowest practical temperature
setting.
Ū Check water temperature after any
adjustment of the mixing valve.
• Failure to comply with these instructions
will result in serious injury, or death.
