CARBON MONOXIDE POISONING HAZARD

Special Warning for Installation of Furnace or Air Handling Units in

Enclosed Areas such as Garages, Utility Rooms or Parking Areas

Carbon monoxide producing devices (such as an automobile, space

heater, gas water heater, etc.) should not be operated in enclosed areas

such as unventilated garages, utility rooms or parking areas because of

the danger of carbon monoxide (CO) poisoning resulting from the exhaust

emissions. If a furnace or air handler is installed in an enclosed area such

as a garage, utility room or parking area and a carbon monoxide producing

device is operated therein, there must be adequate, direct outside

ventilation.

This ventilation is necessary to avoid the danger of CO poisoning which

can occur if a carbon monoxide producing device continues to operate in

the enclosed area. Carbon monoxide emissions can be (re)circulated

throughout the structure if the furnace or air handler is operating in any

mode.

CO can cause serious illness including permanent brain damage or death.

8” (200mm) or more 3. The installation to ceilings varies with construction. Consult construction personnel for the specific procedures. 12” (300mm) or more 4. Install pipes and lines in the ceiling after completion of the installation of the ACNF air handler. The first consideration of installation is to determine the direction of the pipes. When installing in a ceiling, position the refrigerant pipes, drain pipes, indoor and outdoor lines to the connections before hanging the unit. 5.

OUTDOOR UNIT INSTALLATION Place the outdoor unit in such a manner to minimize restriction of discharge air. • Figure 14C Protect the unit from prevailing winds. To ensure the unit operates correctly, place the unit lengthwise along a wall or use a dust or shield plate. • See Figure 15 for minimum distances to obstacles. Two of the three must remain unobstructed.
PAGE 10
See Figure 16 for securing the outdoor unit horizontally to a concrete foundation. Fasten the feet of the outside unit securely with bolt to prevent movement of the unit in adverse weather conditions, such as high winds or earthquake. NOTES: 1. Avoid letting air, dust or other impurities get into the pipe system during installation. 2. The connecting pipe should not be installed until the indoor and outdoor units are installed. The connecting pipe should be kept dry during the installation operation.
PAGE 11
• • Expel the air after connecting the refrigerant pipe with the indoor and outdoor units. Fasten nuts at the repair points. 90 Bend the connecting pipe of small wall thickness. Cut out a desired concave at the bending part of the insulating pipe. Cover exposed portions of the pipe with tape after bending to prevent impurities from entering. Figure 20A Bend the connecting pipe of small wall thickness. Cut out a desired concave at the bending part of the insulating pipe.
