WARNING
!
Do not open the 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
!
Before disassembly of any external compressor component, make sure to relieve possible
internal pressure by loosening the bolts and tapping the component with a soft hammer to
break the seal.
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.
