WARNING
Make sure power to the unit is OFF and
power plug disconnected before replacing
the compressor.
WARNING
Do not use a nitrogen cylinder without a
pressure regulator.
WARNING
Do not open condenser fan grille before
turning power OFF and disconnecting
power plug.
WARNING
Oakite No. 32 is an acid. Be sure that the
acid is slowly added to the water. DO NOT
PUT WATER INTO THE ACID. This will
cause spattering and excessive heat.
WARNING
Wear rubber gloves and wash the solution
from the skin immediately if accidental con-
tact occurs. Do not allow the solution to
splash onto concrete.
WARNING
Always turn OFF the unit circuit breakers
(CB-1 & CB-2) and disconnect main power
supply before working on moving parts.
WARNING
Make sure power to the unit is OFF and
power plug disconnected before servicing
capacitor(s).
WARNING
With power OFF discharge the capacitor
before disconnecting the circuit wiring.
WARNING
The unit power plug must be disconnected
to remove power from circuit breaker CB1
WARNING
Make sure power to the unit is OFF and
power plug disconnected before removing
capacitor(s).
WARNING
Before removing the capacitors, the
terminals must be checked for voltage with
a multimeter. The discharge resistors
installed on the unit (capacitors) should
bring the voltage to a safe level in a minute.
However, there may be a broken resistor
that retains voltage for a longer period.
Therefore, it is highly recommended to wait
15 minutes and to check for voltage.
WARNING
Before disassembly of any external com-
pressor component, make sure to relieve
possible internal pressure by loosening the
bolts and tapping the component with a
soft hammer to break the seal.
CAUTION
Do not remove wire harnesses from con-
troller unless you are grounded to the unit
frame with a static safe wrist strap.
CAUTION
Unplug all controller wire harness connec-
tors before performing arc welding on any
part of the container.
