SAFETY INSTRUCTIONS
1. Read all instructions thoroughly. Failure to do so may
result in system damage and/or personal injury.
2. The system must be pumped down and lines de-
pressurized before attempting to install. Failure to do
so could result in personal injury.
3. Emerson's APD is intended for use with all HFC,
HCFC and CFC refrigerants except R-123 and those
classified by ASHRAE standard 34 as A2, A3, B2 and
B3.
CAUTION: Do not use on unlisted gases or fluids without
prior approval of the Emerson Climate Technologies Flow
Controls Division Applications Engineering Department.
Use on other fluids could result in product deterioration
and/or personal injury.
4. Be sure the muffler is not required to operate at
conditions exceeding the maximum working pressure
of 680 PSIG. Failure to do so could result in personal
injury.
INSTALLATION INSTRUCTIONS
1. Do not remove the APD muffler from the carton until
ready for installation. The seal caps should be
removed only at time of installation. This further
protects the APD from possible contamination.
2. The APD mufflers may be installed in the vertical or
inclined position ONLY. See Tables for roughing - in
dimensions. CAUTION: Installing a standard APD
horizontally could cause oil trapping and loss of
lubrication of the compressor.
3. When soldering divert flame away from the APD to
avoid possible internal damage. Use chill blocks, wet
rags, or other suitable heat protection of the muffler.
4. Pressurize system and check for leaks. If inert gas,
such as nitrogen or carbon dioxide is added to the
system to supplement the refrigerant pressure, it must
be added carefully through a pressure regulator and
pressure relief valve. Unregulated gas pressure can
seriously damage the system and endanger human
life. NEVER use oxygen or flammable gases.
5. If additional repairs are required after the system has
been charged, additional precautions are necessary.
Pump down the entire system, remove refrigerant by
an approved method from the section where repairs
are to be made. Do not use a solenoid valve as a
safety shut-off valve while making repairs to a system.
After reducing the pressure to atmospheric, the
system may be opened and repairs made. The area
should be thoroughly vented to prevent formation of
dangerous fumes, which could result from the
refrigerant being heavier than air.
