•
Typically the fluid circuit with the highest tempera-
ture and/or pressure should be connected to the left
side connections as indicated with the colored label.
• The circuit flows should be piped in a counterflow
arrangement.
• On instantenous water heating applications (applica-
tions without any storage tank) a flow switch must be
used to prevent overheating of the heat exchanger.
• A three-way tempering valve/anti-scalding safety
device is required.
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 temperature settings
of 130ºF or less. Setting thermostat higher than
130ºF will increase the risk of scald injury and
cause severe personal injury or death.
• Water heated to a temperature suitable for
clothes washing, dish washing and other sani-
tizing needs will scald and cause permanent
injury.
DANGER
fig. 8: domestic Piping arrangement
• Children and elderly, infirm, or handicapped per-
sons are more likely to be injured by hot water.
Never leave them unattended in or near a bath-
tub. If anyone using hot water in the building fits
this description, or if state laws or local codes
require certain water temperatures at hot water
faucets, take special precautions.
-
Install an automatic mixing valve at the heat
exchanger or at each hot water faucet, bath
and shower outlet. Selection and installa-
tion must comply with valve manufacturer’s
recommendation and instructions.
- Use the lowest practical temperature set-
ting.
