Hydrostatic Test; Insulation; Maximum External Static Pressures - Carrier AirStream 42BHE06 Installation, Start-Up And Service Instructions Manual

HYDROSTATIC TEST

When all joints are completed, perform hydrostatic test for leaks.
Hydronic systems should be tested with water (some components
are not designed to hold gas). If gas testing is necessary, pressure
must NOT exceed 80 psig. All chilled water piping and valves not
located over drain pans or drip lips must be insulated to prevent
damage from sweating. Vent all coils during final preparations.
(See Step 10, section 6 on page 18.)
WARNING
Never pressurize unit beyond the specified test pressure.
Always pressure test with an inert gas or fluid (nitrogen or
clear water) to avoid possible unit damage or personal injury in
the event of a leak during testing.
Check interior unit piping for signs of leakage from shipping dam-
age or mishandling. If leaks are found, notify your local Carrier
representative before initiating any repairs.
CAUTION
All water coils must be protected from freezing after initial
filling with water. Even if system is drained, unit coils may
still hold enough water to cause damage when exposed to
temperatures below freezing.

INSULATION

Following the hydrostatic test, insulate all piping to unit to prevent
sweating.
