/ Rugged extruded aluminum
frames and protective grilles provide
strength and good looks. Unit will not
sag during rigging.
Low silhouette — The cabinet has no
vents or hoods to break up the clean
appearance. The curb-mounted unit
seldom requires a parapet to hide it
from street level view.
<5 Humidry® coil — This separate
cooling coil dehumidifies the outdoor air
before it is mixed with the return air to
prevent high indoor relative humidities
in humid weather and during partial
load operation.
‘ 5 Large filter area — Over 41 square
feet of standard filter area is factory
supplied. Filter tracks will accept
one-in. or 2-in., high- or low-velocity,
permanent or throwaway, standard or
high-efficiency filters.

heaters have 24-volt relays and 115-volt
contactors. Each heating element has
circuit breakers and automatic thermal
reset. Each leg has its own heat limiter
(fusible link).
Each hot water/glycol heating coil
has its own solenoid operated shutoff
valve and balancing valve. All heating
coils are prepiped to supply and return
manifolds which also include a bleed
valve.
Gas heating (48MA) — Each zone
module has stainless steel burners,
Porcelon™ heat exchangers and its
own redundant gas valve. Natural gas
