ET4BE Series now offers the choice of a
heat pump that uses a more efficient and
environmentally friendly refrigerant designated
R-410A. The ET4BE Series of heat pumps
offers exceptional performance. The unit,
when combined with our engineered coils or
air handlers, offers a full line of quality, split
system cooling equipment.
FEATURES and BENEFITS
• R-410A Refrigerant – Earth friendly non-
ozone depleting refrigerant.
• Designed using galvanized steel – with a
polyester urethane coat finish. The 950
hour salt spray finish resists corrosion 50%
better than comparable units.
• Copper Tube / Aluminum Fin Coils – Both
indoor and outdoor coils are designed to
optimize heat transfer, minimize size and
cost, and increase durability and reliability.
• Permanently Lubricated Motor – A
heavy duty PSC motor for long lasting
reliability and quiet operation. Requires no
maintenance and is completely protected
from rain and snow.
• Composite Base Pan – Absorbs sound and
is corrosion resistant. Composite is also
stronger and lighter than steel.
• Louvered Condenser Guard – Durable
metal guard protects the coil from yard
hazards and extreme weather.
• Removable Top Grille Assembly – Allows
ease of service from the top without
disconnecting fan motor leads.
• High Pressure Switch – Protects against
abnormally high system pressures. Auto-
reset feature prevents nuisance service
visits.
• Liquid Line Filter Drier–Included with unit,
field installed.
• One Piece Top/Orifice – Designed for
maximum airflow and quiet operation.
• Five Minute Restart Time Delay – When the
unit shuts down, a five minute delay keeps
the unit from restarting, eliminating the
highest cause for compressor failure.
• Easy Compressor and Control Access –
Designed to make servicing easier for the
contractor, access panels are provided to
all controls and the compressor from the
side of the unit.
