STULZ CyberRow Chilled Water Series Installation, Operation & Maintenance Manual
1-4
WARNING
This unit is fed by incoming power wires. Even
with the service disconnect switch in the “Off”
position, power may still be “live” between
the switch and the main power source. When
performing service, always ensure main power
is disconnected from the unit.
CAUTION
Equipment may contain components subject to
Electrostatic Discharge (ESD). Before attempting
to mount or service these electronic devices,
ensure you have no charge built up by touching
a ground source. When possible, use a wrist-
grounding strap when working on or near
electronic devices.
CAUTION
Never work on electrical equipment unless
another person, who is familiar with the
operation and hazards of the equipment and
competent in administering fi rst aid, is nearby.
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.
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
The air-intake and discharge areas must be free
of obstructions. Ensure access panels are secure
and latched into position.
CAUTION
Do not use cleaning solvents near open fl ame or
excessive heat. Wear eye protection when blow-
ing 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.
CAUTION
Chilled water cooling coils (and associated piping
circuits) are pressurized with a dry nitrogen
holding charge 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 before allowing
coolant to fl ow through the system. Failure to do
so will result in equipment problems.
CAUTION
When fi lling the chilled water 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.
