[2] Installation and Operation Manual
GENERAL DESCRIPTION
SM Series Water-to-Air Heat Pumps provide the
best combination of performance and efficiency
available. All units are performance certified to
American Heating and Refrigeration Institute
(AHRI) ISO Standard 13256-1. All SM Water-to-Air
Heat Pumps conform to UL1995 standard and are
certified to CAN/CSA C22.1 No 236 by Intertek-
ETL. The Water-to-Air Heat Pumps are designed to
operate with entering fluid temperature between
30°F to 90°F in the heating mode and between
40°F to 120°F in the cooling mode.
Several factory installed options are available:
Heat Recovery Package, Smart Start Assist, DPS
Water Flow Proving Switch, Auxiliary Pump Relay,
and Comfort Alert Module.
Safety devices are built into each unit to provide
the maximum system protection possible when
properly installed and maintained.
MOVING AND STORAGE
If the equipment is not needed for immediate
installation upon its arrival at the job site, it should
be left in its shipping carton and stored in a clean,
dry area. Units must only be stored or moved in the
normal upright position as indicated by the “UP”
arrows on each carton at all times.
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.
LOCATION
To maximize system performance, efficiency and
reliability, and to minimize installation costs, it is
always best to keep the refrigerant lines as short
as possible. Every effort should be made to locate
the air handler and the condensing section as
close as possible to each other.
Condensing Section
Locate the condensing section in an area that
provides sufficient room to make water and
electrical connections, and allows easy removal of
the access panels, for service personnel to
perform maintenance or repair.
The condensing section is designed for indoor use
primarily; however, if the condensing section must
be installed in an outdoors location where ambient
temperatures can fall below freezing, some form of
freeze protection should be employed such as a
freeze-stat and/or a pump timer/starter to prevent
possible condenser freeze-up and to optimize
overall system performance.
50°F Minimum Entering Water Temperature
(EWT) is recommended for well water
applications with sufficient water flow to prevent
freezing. Antifreeze solution is required for all
closed loop applications. Cooling Tower/Boiler
and Geothermal applications should have
sufficient antifreeze solution to protect against
extreme conditions and equipment failure.
Frozen water coils are not covered under
warranty. Other equivalent methods of
temperature control are acceptable.
