4) Once the current has stabilized, a reading should be
taken and the anticipator adjusted to that value. If
longer heating cycles are desired, the anticipator can
be set to a higher value
2.5.2.
Ducts and filters
The ducts must be sized such a way as to accommodate the
specified airflow and the available static pressure. Refer to the
applicable local and/or national installation codes.
Insulate the ducts that lead through non-heated areas. Use
flexible supply and return air connectors to avoid the
transmission of vibration. To make the unit run even quieter,
the installer should:
1) Use two elbows between each outlet and the supply
and return air plenum;
2) Cover the vertical sections of the supply and return air
duct with soundproofing material;
3) Use baffles in short radius elbows;
4) Use flexible hangers to suspend the ducts.
The SUPREME furnace is equipped with a filter frame for the
blower compartment. It must be installed on the outside of one
of the three sides or the bottom of the furnace. Once the
location of the installation has been determined, use the four
square knockouts for ease of cutting the opening.
A heat pump or an air conditioner can be added to this furnace,
in either the supply or return air duct. Carefully follow the
instructions provided with these appliances to ensure proper
installation and hook-up to the electric furnace. Refrigerant and
drainage pipes must in no way hinder access to the furnace
panels.
2.6 SUPPLY AIR ADJUSTMENTS
On units equipped with 4-speed blower motors, the supply air
must be adjusted based on heating/air conditioning output and
the static pressure of the duct system. For the desired airflow,
refer to the following table as well as the airflow tables based on
static pressure in the Technical Specifications section of this
manual.
For the adjustment of the airflow on heating mode, to obtain the
temperature rise described in the technical specification table on
p.10, the orange wire must be positioned on the terminal
corresponding to the LOW, MED-LOW, MED-HIGH or HIGH
blower speed. Blower speed are adjusted in factory for 0.5 inch
static pressure.

For the adjustment of the airflow on air-cooling mode, to obtain
a sufficient airflow (350 to 450 CFM per ton), the blue wire must
be positioned on the terminal corresponding to the LOW, MED-
LOW, MED-HIGH or HIGH blower speed. Blower speeds are
adjusted in factory for 0.5 inch static pressure.

2.7 INSTALLATION OF ACCESSORIES
WARNING
Electrical shock hazard.
Turn OFF electrical power at the fuse box or service panel
before making any electrical connections and ensure a
proper ground connection is made before connecting line
voltage.
Failure to do so can result in death or bodily injury.
