To avoid equipment damage, DO NOT use
these units as a source of heating or cooling
during the construction process. Doing so
may affect the unit's warranty. The
mechanical components and filters will
quickly become clogged with construction
dirt and debris, which may cause system
damage.

INITIAL INSPECTION

Be certain to inspect all cartons or crates on each
unit as received at the job site before signing the
freight bill. Verify that all items have been received
and that there are no visible damages; note any
shortages or damages on all copies of the freight
bill. In the event of damage or shortage, remember
that the purchaser is responsible for filing the
necessary claims with the carrier. Concealed
damages not discovered until after removing the
units from the packaging must be reported to the
carrier within 24 hours of receipt.

GENERAL DESCRIPTION

The LM Split System Water-to-Air Heat Pumps
provide the best combination of performance and
efficiency available. Safety devices are built into
each unit to provide the maximum system
protection possible when properly installed and
maintained.
Split system heat pumps consist of two
independently installed sections allowing for
centralized air distribution while remotely locating
the section containing the compressor and water-
to-refrigerant heat exchanger.
8 733 920 847 (2014/01)
In the cooling mode, the air coil in the air handler
section serves as an evaporator and the water-to-
refrigerant heat exchanger serves as a condenser.
In the heating mode, their roles are reversed. The
refrigerant lines connecting the two sections
consist of one line carrying liquid refrigerant and
another carrying refrigerant vapor. The liquid
carrying line will be referred to as the liquid line
while the vapor carrying line will be referred to as
the suction line.
The LM Split AH Water-to-Air Heat Pump units are
performance certified to American Heating and
Refrigeration Institute (AHRI) ISO Standard 13256-
1. All LM Water-to-Air Heat Pumps conform to
1
UL1995 standard and are certified to CAN/CSA
C22.1 No 236 by Intertek-ETL.
NOTE: This product should not be used for
temporarily heating/cooling during
construction. Doing so may effect the units
warranty.

SAFETY CONSIDERATIONS

Installation and servicing of this equipment can be
