HEAT DX COOL AIR HANDLERS

STANDARD FEATURES

APPLICATION VERSATILITY

Front or bottom return air. Offset hanging brackets attach to unit and wall to
allow hanging inside closet. Can be AHRI matched with most brands of air con­ditioners or heat pumps. ETL listed for use with either R22 or R410a when a
proper metering device is used.

LOW LEAKAGE CABINET

Less than 2% air leakage from cabinet when tested in accordance with
ASHRAE standard 193. Unit must be installed according to Aspen installation
instructions. Sturdy, fully insulated galvanized steel cabinet; stick pins ensure
1/2” insulation remains in place. Unit ships with disposable filter.

MODULAR HYDRONIC HEAT KITS

Heat kits available with either circuit breakers or terminal blocks. Available in 2,
3 & 4 row, providing 16,000 to 59,000 BTU’s of heat. Heat kits are easily in­stalled in the field using molex plugs or can be ordered factory-installed. Freeze
stat is standard, wired into circulating pump control circuit. Controls are ac­cessible from the front for easy service. Electrical connections can be made
from the top or left. Disconnect does not protrude through the wall panel. Fan
time delay relay standard for increased efficiency. Heat kits are available with
or without circulating pump and check valve. Units are provided with auxiliary
relay for remote pump. Schrader ports are standard on water-out manifold,
hose bib available as an option. Totally lead free constructed coil. Suitable for
potable applications.

BLOWER

Direct drive multi-speed blowers circulate air quietly and efficiently. Motor
speeds can be easily selected via motor terminals. Swing mounted blowers
can be easily removed for service.

ELECTRONIC CONTROL BOARD

An electronic board controls the functioning of the system reducing moving
parts. The board provides for various hot water supply source connections
and the blower time delay to maximize heat/cool extraction. As an enhanced
feature the pump circulates hot water every 6 hours to prevent coil freeze
during off cycle.

DX COIL

High efficiency rifled copper tubes/enhanced aluminum fins provide maximum
heat transfer. All coils immersion tested at 500 psi then nitrogen pressur­ized and factory sealed for maximum reliability. Liquid-line Schrader allows
pre-installation pressure testing. Available with either check style flowrater or
TXV metering device. Field-installable TXVs are also available. Galvanized metal
drain pan with bottom primary and secondary drain connections or alternate
right side primary. All connections 3/4” FPT. Access door allows for coil clean­ing.

WARRANTY

Five-year limited parts warranty.
