Important notes For the Installer
A Quick Check List
Are the water connections to the water heater oriented in a way to
avoid trapping air in the heating circuit? (see diagram on next page)
Is the purge valve installed on the return line from the air handler
upstream from the isolation valve?
Is the air handler hung and isolated to avoid transmitting vibration
through framing and duct work? Or is the air handler on a
housekeeping pad?
Are the isolation valves full-port? estrictive valves will limit
performance.
Are Thermostat connections correct, including cooling and continuous
run connections?
Have the packing materials been removed from the blower and the
pump ?
Is there an installation manual for the home owner ?
Is the unit accessible? Are there clearances for service and component
replacement?
Are the supply plenum and return duct/drop acoustically lined ? (at
least 6ft. of the return duct/drop and the supply plenum are
recommended)
Is the filter cover in place? Is a clean filter in place? Is the supplied
filter rack installed?

INT ODUCTION
combo-pac ™ air handlers are state-of-
the-art units designed for use with
hydronic (boiler) systems or in
combination space and water heating
systems (Combo Systems). Two key
features include automatic heating
capacity adjustment and automatic
cooling dehumidification adjustment.
The programmable control allows for
customization and adjustment of air
speeds and capacity. Combo heating
systems use the home’s water heater to
provide both the space heating and
domestic hot water, eliminating the need
for a furnace.
Combo heating systems are ideally
suited for single-family homes,
townhouses and apartments where the
cost of a furnace does not make sense or
space requirements are limited. They
are also great for additions, renovation
and finished basements as a
replacement for, or in addition to the
existing heating system. Vortex air
handlers are also great for hydronic
heating systems using ground-source
heat pumps. They are the smallest units
available in their capacity range.
combo-pac ™ air handlers are designed
to take the guesswork out of system
sizing and installation. Matched
specifically to common water heater
sizes, Vortex air handlers can be quickly
sized using the quick sizing information
in our spec sheets or from air handler
performance curves. For applications
requiring special consideration, call
888-781-8151 for answers to questions
related to sizing, installation or trouble-
shooting for any of Vortex air handlers.
Vortex provides you with the quietest
operating air handler available. By using
large capacity, high output heating coils,
these air handlers deliver more heating
per volume of air, which means warmer
delivered air temperatures.
combo-pac™ air handlers are intended
for conventional and small-D™ duct
systems with higher operating static
pressure. efer to the small-D™ design
manual for more details on duct design
and installation.
