Section 1. Safety
Important - This document contains a wiring diagram
and service information. This is customer property and is
to remain with this unit. Please return to service
information pack upon completion of work.
Failure to follow this warning could result in property
damage, severe personal injury, or death.
Disconnect all electric power, Including remote disconnects
before servicing. Follow proper lockout/tagout procedures
to ensure the power cannot be inadvertently energized.
HAZARDOUS VOLTAGE!
Any attempt to repair a central air conditioning product
may result in property damage, severe personal injury,
or death.
These units use R-410A refrigerant which operates at
50 to 7o% higher pressures than R-22. Use only
R-410A approved service equipment. Refrigerant cylin-
ders are painted a “Rose” color to indicate the type of
refrigerant and may contain a “dip” tube to allow for
charging of liquid refrigerant into the system. The R410
system of 2/3 tons with MITSUBISHI variable compres-
sor uses PVE oil ( FV50S or equal ), and the R410
system of 4/5 tons with GMCC variable compressor
uses POE oil ( VG74 or equal ). Both of them readily
absorb moisture from the atmosphere.To limit this
‘hygroscopic“ action, the system should remain sealed
whenever possible. If a system has been opened to the
atmosphere for more than 4 hours, the compressor oil
must be replaced. Never break a vacuum with air and
always change the driers when opening the system for
component replacement.
May cause minor to severe burning. Failure to follow
this caution could result in property damage or
personal injury. Do not touch top of compressor.
REFRIGERANT OIL!
HOT SURFACE!
Failure to follow proper procedures can result in
personal illness or injury or severe equipment damage.
System contains oil and refrigerant under high pres-
sure. Recover refrigerant to relieve pressure before
opening system.
CONTAINS REFRIGERANT!
Failure to inspect or use proper service tools may
result in equipment damage or personal injury.
Reconnect all grounding devices. All parts of this
product that are capable of conducting electrical
current are grounded. if grounding wires, screws,
straps, clips, nuts, or washers used to complete a
path to ground are removed for service, they must be
returned to their original position and properly
fastened.
GROUNDING REQUIRED!
Failure to follow this warning will result in abrupt
release of system charge and may result in personal
injury and/or property damage. Extreme caution
should be exercised when opening the Liquid Line
Service valve. Turn valve stem counterclockwise only
until the stem contacts the rolled edge. No torque is
required.
SERVICE VALVES!
Failure to inspect lines or use proper service tools
may result in equipment damage or personal injury.
if using existing refrigerant lines make certain that all
joints are brazed, not soldered.
BRAZING REQUIRED!
Failure to follow this warning could result in property
damage, severe personal injury, or death.
Earth connection essential before connecting electri-
cal supply.
