Thoroughly flush all water piping to the unit before making
the final piping connections to the unit.
Components and layout will vary slightly, depending on the
location of connections and the water source.
NOTICE
Evaporator Damage!
Failure to follow instructions below could cause
damage to the evaporator.
The chilled water connections to the evaporator are to
be grooved-pipe type connections. Do not attempt to
weld these connections, as the heat generated from
welding can cause microscopic and macroscopic
fractures on the cast iron waterboxes that can lead to
premature failure of the waterbox. To prevent damage
to chilled water components, do not allow evaporator
pressure (maximum working pressure) to exceed 150
psig (10.5 bar).
NOTICE
Equipment Damage!
Failure to follow instructions below could result in
damage to internal components of the evaporator.
If using an acidic commercial flushing solution when
flushing the water piping, construct a temporary
bypass around the unit.
NOTICE
Water Borne Debris!
To prevent components damage, pipe strainers must
be installed in the water supplies to protect
components from water borne debris. Trane is not
responsible for equipment-only-damage caused by
water borne debris.
