•
Do not operate the instrument around
explosive gas, vapor, or dust.
•
Various refrigerants have been intentionally
excluded for very significant safety reasons.
Never use refrigerants in this instrument
that are not listed in the Set-up menu.
•
The refrigerant database in this unit may
include refrigerants classified as flammable.
If such refrigerants are selected, the
operator may need additional certifications
and/or training. Consult your government
and legal authority and comply fully with all
requirements.
•
Always wear eye and skin protection when
working with refrigerants. Escaping
refrigerant vapors will present a freezing
danger. Do not direct refrigerant vapors
venting from hoses towards the skin.
•
Maximum Working Pressure: 700 psia (4.83
MPa)
•
Because this instrument allows for various
inputs including electrical and mechanical,
care must be taken to observe any ways
that an electrical shock hazard could
develop. Example: Wet or humid conditions,
along with a damaged thermocouple or
vacuum sensor, could allow an electrical
path across the instrument and over wet
hoses. Keep all interconnected equipment
clean, organized, and in proper condition.
Do not use the instrument if you are not
qualified to recognize potential electrical
faults.
To avoid damage to equipment, follow these
guidelines:
•
Do not allow pressures beyond the
specifications listed in this manual.
•
Be aware that internal pressures can change
unintentionally when equipment is stored
with pressure in the system during
temperature changes. If sub-cooled liquid
refrigerant is trapped in a hose or manifold
with no room for expansion, it may result in
dramatic pressure variations with seemingly
small temperature changes. Pressures can
reach high enough levels to cause damage
to the instrument’s internal pressure
transducers. Release liquid refrigerant from
the hoses and manifold when disconnecting
from a system.
•
Do not attempt to introduce liquid or
samples heavily laden with oil into the
instrument.
•
Do not use this instrument on systems
containing leak sealing chemicals. These
leak sealants can collect and harden in the
instrument, causing permanent damage.
