ATTACHING HORIZONTAL DUCTWORK TO UNIT

All conditioned air ductwork should be insulated to minimize heating

and cooling duct losses. Use a minimum of two (2) inches of

insulation with a vapor barrier. The outside ductwork must be

weatherproofed between the unit and the building.

When attaching ductwork to a horizontal unit, provide a flexible

watertight connection to prevent noise transmission from the unit to

the ducts. The flexible connection must be indoors and made out

of heavy canvas.

NOTE: Do not draw the canvas taut between the solid ducts.

DUCTWORK

ATTACHING DOWNFLOW DUCTWORK TO ROOF CURB

Supply and return air flanges are provided on the roof curb for easy

duct installation. All ductwork must be run and attached to the curb

before the unit is set into place.

Follow these guidelines for ductwork construction:

Connections to the unit should be made with three-inch canvas

connectors to minimize noise and vibration transmission.

Elbows with turning vanes or splitters are recommended to mini-

mize air noise and resistance.

The first elbow in the ductwork leaving the unit should be no closer

than two feet from the unit, to minimize noise and resistance.

The following warning complies with State of California law, Proposition 65.

WARNING:

This product contains

fiberglass wool insulation! Fiberglass dust and ceramic

fibers are believed by the State of California to cause

cancer through inhalation. Glasswool fibers may also

cause respiratory, skin, or eye irritation.

PRECAUTIONARY MEASURES

● Avoid breathing fiberglass dust.

● Use a NIOSH approved dust/mist respirator.

● Avoid contact with the skin or eyes. Wear long-

sleeved, loose-fitting clothing, gloves, and eye

protection.

● Wash clothes separately from other clothing: rinse

washer thoroughly.

● Operations such as sawing, blowing, tear-out, and

spraying may generate fiber concentrations requiring

additional respiratory protection. Use the appropriate

NIOSH approved respirator in these situations.

FIRST AID MEASURES

Eye Contact - Flush eyes with water to remove dust.

If symptoms persist, seek medical

attention.

Skin Contact - Wash affected areas gently with soap

and warm water after handling.
