INSTALLER'S GUIDE
IMPORTANT:
Wear appropriate gloves, arm sleeve protectors,
and eye protection when servicing or maintaining this equipment.
IMPORTANT:
Proper refrigerant charge and proper air flow are
critical to achieve rated capacity and efficiency. Installation of
this product should follow the manufacturer’s refrigerant charging
and air flow instructions.
Failure to confirm proper charge and
airflow may reduce energy efficiency and shorten equipment
life.
IMPORTANT:
Reconnect all grounding devices. All parts of this
product 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.

CONTAINS REFRIGERANT!
SYSTEM CONTAINS OIL AND REFRIGERANT UNDER
HIGH PRESSURE. RECOVER REFRIGERANT TO RELIEVE
PRESSURE BEFORE OPENING SYSTEM. Failure to follow
proper procedures can result in personal illness or injury
or severe equipment damage.

RECONNECT ALL GROUNDING DEVICES.
All parts of this product that are capable of conduct-
ing 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.
CAUTION
!
Hot Surface!
Do Not touch top of compressor. May cause minor to severe
burning.
Unit contains R-410A Refrigerant!
R-410A operating pressure exceeds the limit of R-22. Proper
service equipment is required. Failure to use proper service
tools may result in equipment damage or personal injury.
SERVICE
Use only R-410A Refrigerant and approved POE com-
pressor oil.
These units use R-410A refrigerant which operates at
50 to 70% higher pressures than R-22. Use only R-410A
approved service equipment. Refrigerant cylinders are
painted a “Rose” color to indicate the type of refriger-
ant and may contain a “dip” tube to allow for charging
of liquid refrigerant into the system. All R-410A sys-
tems use a POE oil that readily absorbs moisture from
the atmosphere. To limit this “hygroscopic” action, the
system should remain sealed whenever possible. If a
system has been open 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.
For specific handling concerns with R-410A and POE oil
reference Retrofit Bulletins SS-APG006-EN and APP-
APG011-EN.

WARNING
Important:
Make sure to follow all safety precautions in the
unit Installer's Guide.
Important: Make certain that the unit has been installed in
a level position to ensure proper draining.
STEP 1
- Recover refrigerant, disconnect power leads
and remove mounting washers/nuts and set aside
from the existing compressor. Also disconnect LPCO
wires from the wire termination point. If a start kit is
installed, remove it.
Section 2. Installation
CAUTION
!
If using existing refrigerant lines make certain that all joints
are brazed, not soldered.
