INSTALLATION CONTINUED
CONDENSATE DRAINAGE
Condensate drain lines must be properly installed with
adequate slope away from unit to ensure proper drainage.
A minimum trap of 1.5 inches must be installed to isolate
the negative pressures of the drain pan from the drain line.
Refer to
Figure 10 – Condensate Drainage for schematic
information on the condensate drain lines.

Check the condensate overflow sensor for proper
operation and adjust if necessary. Final field adjustments
ensures proper operation to avoid property damage.

On units with plastic drain pans, the drain connection must
be made hand tight only.

Both the supply and return water lines will sweat if
subjected to low water temperature. These lines should be
insulated to prevent water damage to the property.

Units equipped with the economizer option must have a
separate externally trapped drain line for condensate
removal.
Insulation is not required on loop water piping except
where the piping runs through unconditioned areas,
outside the building or when the loop water temperature is
below the minimum expected dew point of the pipe
ambient conditions. Insulation is required if loop water
temperature drops below the dew point.
Units are supplied with either a copper or optional cupro-
nickel water to refrigerant heat exchangers. Copper is
adequate for ground water that is not high in mineral
content. Should your well driller express concern regarding
the quality of the water or should any known hazards exist
in your area then we recommend proper testing to assure
the well water quality is suitable for use with water source
equipment. In conditions anticipating moderate scale
formation or in brackish water a cupro-nickel heat
exchanger is recommended.

DUCTWORK
Discharge ductwork is normally used with these units.
When return air ductwork is required, the unit is supplied
with 1-inch filter rack/duct collar for connection of return
air ductwork. All ductwork must be installed in accordance
with National Fire Protection Assoc. Codes 90A and 90B.
Supply and Return ducts must be sized properly as to not
exceed static pressure capabilities Ducts should be
adequately insulated to prevent condensation and to
minimize heat loss. A flexible connector is recommended
for supply air connections on metal duct systems.
