ACCESSORIES
Refer to Price Manual for specific model numbers where not
shown.
TXV Kits - Air handlers are shipped with “Flex-coils” without a
factory installed metering device. For added flexibility, an R-22
or R-410A TXV or piston can be field installed to meet your
refrigerant choice. All TXV kits are chatleff style and require no
brazing to install. Some models are available with a factory
installed TXV.
Electric Heaters - 6HK models shown under electrical data
include sequential operation and temperature dual limit
switches for safe, efficient operation. Service disconnects are
provided where shown.
Combustible Floor Base Accessory - If an electric heat
accessory which is rated for greater than zero clearance to
combustible surfaces is installed in these air handlers in the
downflow operating positions on a combustible floor, one of the
following combustible floor base accessory models is required:
S1-1FB1917, S1-1FB1921, S1-1FB1924.
Breaker Moisture Seal Accessory - A clear circuit breaker
moisture barrier seals the breakers from humidity and dust. The
flexibility of the clear cover allows circuit breakers to be turned
ON or OFF without removing the cover. The cover firmly
attaches to the access panel around the circuit breakers with
the use of double backed adhesive tape. To ensure that
moisture or dust does not contaminate circuit breakers, an S1-
02435672000, Circuit Breaker, Cover Seal may be ordered.
Thermostat - Compatible thermostat controls are available
through accessory sourcing. For optimum performance, these
outdoor units are fully compatible with our York touch screen
thermostat with proprietary (patent-pending) hexagon interface.
For more information, see the thermostat section of the Product
Equipment Catalog.
