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.

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 Table 1 and 2, as well as the
Tables 4 and 5 for the airflow based on static pressure.
For the adjustment of the airflow on heating mode, to obtain
the temperature rise described in the technical specification
table (Table 3), the orange wire must be positioned on the
terminal corresponding to the LOW, MED-LOW, MED-HIGH
or HIGH blower speed.
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.
