STULZ CyberRow DX Series Installation, Operation & Maintenance Manual

WARNING
All personnel working on or near equipment
should be familiar with hazards associated
with electrical maintenance. Safety placards/
stickers have been placed on the unit to call
attention to all personal and equipment damage
hazard areas.
WARNING
Refrigerant R410A may be used with this
equipment. Death or serious injury may result
if personnel fail to observe proper safety
precautions. Great care must be exercised
to prevent contact of liquid refrigerant or
refrigerant gas, discharged under pressure,
with any part of the body. The extremely low
temperature resulting from the rapid expansion
of liquid refrigerant or pressurized gas can
cause sudden and irreversible tissue damage.
As a minimum, all personnel should wear ther-
mal protective gloves and face-shield/goggles
when working with refrigerant. Application of
excessive heat to any component will cause
extreme pressure and may result in a rupture.
Exposure of refrigerant to an open fl ame or a
very hot surface will cause a chemical reaction
that will form carbonyl chloride (hydrochloric/hy-
drofl uoric acid), a highly poisonous and corro-
sive gas commonly referred to as PHOSGENE.
In its natural state, refrigerant is a colorless,
odorless vapor with no toxic characteristics. It
is heavier than air and will disperse rapidly in
a well-ventilated area. In an unventilated area,
it presents a danger as a suffocant.
Always refer to the manufacturer’s MSDS pro-
vided with the unit.
CAUTION
Certain maintenance or cleaning procedures
may call for the use and handling of chemicals,
solvents, or cleansers. Always refer to the
manufacturer’s Material Safety Data Sheet
(MSDS) prior to using these materials. Clean
parts in a well-ventilated area. Avoid inhalation
of solvent fumes and prolonged exposure of
skin to cleaning solvents. Wash exposed skin
thoroughly after contact with solvents.
CAUTION
Do not use cleaning solvents near open fl ame
or excessive heat. Wear eye protection when
blowing solvent from parts. The pressure-wash
should not exceed 30 psig. Solvent solutions
should be disposed of in accordance with local
and state regulatory statutes.
WARNING
When performing brazing or debrazing
operations, make certain the refrigeration
system is fully recovered and purged and dry
nitrogen is fl owing through the system at the rate
of not less than 1-2 CFM (0.03-0.06M³/minute).
CAUTION
The air-intake and discharge areas must be
free of obstructions. Ensure access panels are
secure and latched into position.
CAUTION
Cooling coils (and associated piping circuits)
are pressurized and sealed when they leave
the factory. Before installing the interconnecting
piping, observe appropriate safety precautions
and release the pressure via an available stem
valve or schrader valve prior to uncapping the
pipes.
CAUTION
After interconnecting piping is installed, the
piping system must be cleaned.
If solvents/
cleaning solutions are used, ensure they are
completely fl ushed from the piping before
connecting it to the unit.
Failure to do so will
result in equipment problems.
CAUTION
When fi lling the chilled water or water/glycol
loop, all air must be bled from the piping system.
WARNING
Do not use chloride based water conditioning
additives in the condensate drain pans. This
will cause corrosion to occur on the coil fi ns.
