*RHSA(L)-HM6024JA is ARI rated for three phase
application only.
• Supply circuit protective devices may be fuses or
“HACR” type circuit breakers.
• Largest motor load is included in single circuit
and multiple circuit.
• If non-standard fuse size is specified, use the next
larger fuse size.
• J Voltage (230V) single-phase air handler is
designed to be used with single or three phase
230 volt power. In the case of connecting 3-phase
power to the air handler terminal block, bring
only two leads to the terminal block. Cap, insulate and fully secure the third lead.
• The air handlers are shipped from the factory with
the proper indoor coil installed, and cannot be
ordered without a coil.
• The air handlers do not have an internal filter
rack. An external filter rack or other means of
filtration is required.
