WELCOME TO THE SMALL DUCT HIGH
VELOCITY SYSTEM
You are now the owner of a Heat Controller Small Duct High Velocity System
that utilizes the most modern concepts in cooling, heating, and air distribution.
Whether yours is a separate cooling system designed for summer air
conditioning, or a total comfort system, this equipment works best when properly
operated and cared for.
For a system that includes electric heater(s) or hot water heating coil(s), no
owner maintenance or care under normal operating conditions is required for these
heating options.
Heat Controller’s blower motor has permanently lubricated sealed bearings
which do not require lubrication.

THERMOSTAT OPERATION
COOLING ONLY:
Thermostats are provided in several
configurations and styles. For a
cooling-only system, the thermostat will
provide a FAN SWITCH that can be set
for either continuous (ON) or
intermittent (AUTO) blower operation
and a SYSTEM SWITCH that can be
set to COOL (it may also be marked
AUTO) or OFF. The OFF position
shuts down all operation of the system.
COOLING AND HEATING:
With a combined cooling and heating
system, your thermostat controls both heating and cooling. An additional marking
on the system switch (HEAT) determines the change over from cooling to heating.
HEAT PUMP OPERATION:
A heat pump system operates as a reverse air conditioner by cooling the outside
air and heating the indoor air. During the heat cycle the outdoor unit will
occasionally go into a “defrost” mode to rid itself of any ice that forms on the
outdoor unit. The system will blow cold air during the brief period. An electric duct
heater may be installed as an option to raise the duct temperature during this
mode. However, it is not normally used because the SDHV system does not create
drafts.

THERMOSTAT OPERATION
USING THE SWITCHES
System Switch:
__COOL_OFF_HEAT
Set it to HEAT in the winter and
COOL in the summer. In the OFF
position the entire system is shut
down regardless of thermostat
temperature setting.
Fan Switch: ON
__ For Maximum Comfort.
You may find it more
comfortable to operate the fan
continuously set at the ON position.
This increases power consumption
slightly, but it assures a constant
compressor or heater cycles to
maintain the selected temperature.
Fan Switch: AUTO
__ For Comfort and Economy.
When set to AUTO during the
cooling cycle the fan will operate
only when the compressor is
running. This provides maximum
dehumidification with a slight
increase in the temperature
variation.
A Helpful Hint:
For more uniform temperature and
humidity control when cooling, leave the
thermostat set at one temperature.
Since your new SDHV system draws out
more moisture for the air then a
conventional system, you may find
satisfactory comfort levels at higher
temperature settings (saving on the
amount of time your cooling system is
consuming power).
Temperature Dial:
__ Set the thermostat to the desired
temperature.
Setting the temperature below the
desired temperature will not cool faster
and it could increase operating costs if
left there.
Emergency Heat (Heat Pump systems
with electric duct heater installed): __ If
the heat pump fails for some reason, or if
the outdoor temperature is very low, you
may find that the system maintains the
room temperature if you operate only the
electric duct heater by moving the
system switch to EMGENCY HEAT.

PERIODIC MAINTANCE
1. FILTER CLEANING:
Clean your filter at least once per month or as often as necessary.
Maintenance of the filter is the most important thing that you can do to help insure
the efficient performance of your system.
Unlatch Cover Plate on Return Grille
A dirty or clogged filter can seriously impair performance. The filter is located
inside the return air grille box. (See Illustration*)
Unlatch the side of the louvered cover plate and let the hinged cover drop down
revealing the filter.
4
KEEPING YOUR FILTER CLEAN (cont’d)
•Remove Filter
Turn filter retaining
tabs or remove filter
retaining clips and
carefully remove the filter.
•Clean or Replace Filter
If your filter is a reusable
media type which consists
of expanded aluminum foil
encased in an aluminum
frame, hose off, spraying
from the side opposite the
air flow direction, then
lightly coat or spray media
with filter oil.
If a higher efficiency
replaceable filter is used,
replace it with a like sized filter __contact your authorized contractor for
replacements.
Where an electronic air cleaner is used, the collecting cell must be
cleaned to remove any dirt accumulation. Consult the instructions
furnished with the air cleaner.
NOTE: In basement or utility room installations, especially where a
vertical blower coil unit is used, the filter may be mounted directly in a
filter frame on the unit or in a cabinet base under the unit. Check with
your authorized contractor on filter removal.
5
Note: For continued good performance it is recommended that you have your
system serviced annually by an authorized installing contractor.
CAUTION: Avoid accidental harm
when opening the hinged cover plate
of a ceiling installed return air grille.
Set your ladder on the latch side so
that the cover will fall downward and
away from you instead of toward
you.

PERIODIC MAINTENANCE
2. WINTERIZE YOUR SYSTEM WITH
AIR SUPPLY SHUT OFFS
If the blower coil unit and air
distribution system are located in an
unheated area such as the attic (and
the system is used for cooling only),
winterizing the system helps prevent
any accumulation of moisture in the
duct work.
•Plug Air Outlets (Optional)
Winter supply air shut-offs are available
to plug off each air outlet. A plate
should also be installed across the face
of the filter in the return air box.
Check with your authorized
contractor to provide these optional
items.
3. CHECK CONDENSATE TRAP
AND DRAINS
The condensate drain should be
checked periodically to assure there is
unimpeded flow of condensate water
from the blower coil drain pan. At the
start of each cooling season it is
advisable to flush the drain pan, drain
trap and line with water. Dirt can
accumulate in the trap and block the
drain opening. Also check the drain
connection on the secondary drain pan
when provided under the unit. This
drain must also remain unclear to
provide the back-up protection
intended.
On cooling only installations where the
blower coil unit is located in areas such
as attics, which may be subject to
freezing, the drain trap should be
drained or filled with anti-freeze/water
mixture.
4. KEEP OUTDOOR UNIT FREE OF
DEBRIS
The outdoor condensing unit should
be checked periodically to assure
trouble free operation.
•SHUT OF POWER __
SEE “UNIT DISCONNECTION”
IMPORTANT: Shut off power to the
condencing unit before washing or
working near the unit.
•Clean Outdoor Condensing Unit
Keep leaves, grass, and foreign
matter out of the condenser coil
by flushing clean with a garden
hose (check condensing unit
manufacturer’s instructions).
Keep the condenser fan blades
clear of dirt and dust
accumulation.
•Trim Shrubbery
Keep shrubbery trimmed around
the unit to maintain unrestricted
air flow to and from the
condenser coil.
5. CONDENSING UNIT
LUBRICATION
Check the manufacturer’s
instructions for the condenser fan
motor lubrication recommendations. If
the motor does not have oil holes for
tubes, it is permanently lubricated and
requires no oiling.

MAINTENANCE/UNIT DISCONNECTION
Outdoor Condensing Unit
Typical __ Configuration may vary
•
Disconnect Switches:
Be sure you know where the
power disconnect switches are
located for both the indoor blower
coil unit and the outdoor
condensing unit. If unusual noise,
vibration or any other
uncharacteristic performance is
evident do not hesitate to turn off
the blower coil unit and condensing
unit with the disconnect switches
and call your authorized contractor.

P.R.O.S.
(POSITIVE REGULAR OPERATING STEPS)
Help maximize the efficiency and economy of your stem by following these simple
guidelines:
•
Keep all windows and doors closed.
If storm windows are used, keep
them in place during the cooling
season to help reduce heat gain.
Pull drapes or shades where the
sunlight is streaming through the
windows during the cooling season.
During the winter, keep drapes and
shades open during the day,
allowing the sun to provide
supplementary heat.
•Keep filters clean, replace
disposable types periodically.
Check the filter monthly.
•Vent clothes dryer to the outside __
otherwise the moisture from
washing mush be removed by the
cooling system.
•Keep attic vents open and use an
attic power ventilator to reduce attic
temperatures. Attic space can
become extremely hot unless it is
well ventilated.
•Take advantage of the great
dehumidifying effect. Comfort levels
can be maintained at higher
thermostat levels settings than with
conventional systems that take out
30% less moisture.
•Set thermostats at the desired
temperature and forget it.
Thermostat jiggling only aggravates
the system causing frequent
changes in humidity level and by
increase operating costs.
•Leave the system on even when
away for a day or more. When the
system is off, heat and moisture
build up in the house and it can cost
more to restore comfort than to
maintain it.
•If possible, do those chores that
contribute heat and moisture
(washing, drying, mopping, etc.) in
the morning or evening. This
permits the cooling system to
overcome the added loads of these
activities before (or after) the peak
load in the afternoon.
•Use bathroom exhaust fans or open
windows slightly during showers or
baths to let excess moisture
escape.
•Use kitchen exhaust fans when
cooking during the cooling season.
Heat added by a cooking device
must be removed by your cooling
system if not exhausted.
•Expect the unit to operate after
sundown
__ heat builds up in the structure and
is retained after the sun sets. This
“flywheel” effect can be overcome
by operating the system even when
outdoor temperatures have
dropped.
•Keep windows closed after the sun
sets. While night air may be cooler,
it may be humid and can cause
equipment to run longer the next
day.
•Keep outdoor condensing unit free
of shrub overgrowth and vegetation.
Assure unrestricted air flow for
intake and discharge of the
condensing unit.
•Keep heat generating devices such
as lamps, TV or electronic
equipment away from vicinity of the
thermostat so it can more
accurately sense room temperature.
