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)
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.

Bulletin 100-00 — OWNER'S MANUAL
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.
Note: For continued good performance it is recommended that you have your
system serviced annually by an authorized installing contractor.
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
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.
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.
