Trane YCZ035F1 Horizontal, Attaching Downflow Ductwork To Roof Curb, First Aid Measures

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.

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.

●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
