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 COMPRESSOR
OIL.
(_)
5 FT. ABOVE UNiT -- UNRESTRICTED
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 refrigerant
and may
contain a "dip" tube to allow for charging of liquid refriger-
ant into the system. All R-410A systems
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 alwags
change the driers when opening the system for component
replacement.
For specific handling
concerns
with R-410A
and POE oil, reference Retrofit Bulletin TRN-APGO2-EN.
Check for transportation
damage after unit is uncrated.
Report promptly, to the carrier, any damage found to the unit.
To determine the electrical power requirements
of the unit,
refer to the nameplate of the unit. The electrical power
available must agree with that listed on the nameplate.
The Weathertron
® Heat Pump has been designed
and manu-
fhctured to withstand
and operate
in severe winter
condi-
tions. However,
there are precautionary
steps which should
be taken
at the time of installation
which will help assure
the efficient operation
of the unit. It is recommended
that
these
precautions
be taken
for units
being
installed
in
areas
where
snow
accumulation
and prolonged
below
freezing
temperatures
occur.
1. Units should be elevated three (3) to twelve (12) inches above
the pad or rooftop, depending
on local weather. This addi-
tional height will allow better drainage of snow and ice
(melted during defrost cycle) prior to its refreezing. This
should prevent
a build-up
of ice around
the unit which
occurs when unit is not elevated. Insure
that
drain
holes in unit
base pan
are not obstructed
preventing
draining
of defrost
water.
2. If possible,
avoid locations
that are likely to accumulate
snow drifts. If not possible,
a snow drift barrier
should be
installed
around
the unit to prevent
a build-up
of snow on
