The California Safe Drinking Water and Toxic Enforcement Act requires the Governor of California to publish a list of substances known to the State of California to cause cancer, birth defects, or other reproductive harm, and requires businesses to warn of potential exposure to such substances. WARNING: This product contains a chemical known to the State of California to cause cancer, birth defects, or other reproductive harm. This appliance can cause low-level exposure to one of the substances listed: formaldehyde. 065715702

Prepare Evaporator Coils Orifice Extension Stub--After Removal of Shipping Strap A IMPORTANT: B This evaporator coil was manufactured containing a dry air precharge of 10 psi. Slowly remove the rubber line seal plugs A. Orifice extension stub to relieve the dry air precharge pressure. B.

IMPORTANT: The proper orifice size is dependent on indoor coil/ 8. Assemble the brass hex nut and orifice extension stub onto outdoor unit combination and application. Consult the outdoor the distributor/orifice assembly as shown. unit information to determine if the indoor unit has the correct orifice installed. NOTE: Overtightening the brass hex nut will crush the gasket and might result in a system leak or stuck piston. Assemble Distributor/Orifice 9. Dispose of/recycle all packaging and unused parts. 1. Remove the brass hex nut from distributor/orifice assembly. 2. Remove the line seal plug from the orrifice assembly. Install Evaporator Coil 3. Unscrew and remove the shipping strap from the orifice IMPORTANT: extension stub. Remove the orifice extension stub from the panel. The evaporator coil must be installed in the discharge 4. Relocate the ring seal to the stub end of the orifice extension (supply) air of a gas or oil furnace. Do not install an stub as shown. evaporator coil in the return air, or excessive condensation will occur within the furnace. Orifice Extension Stub--Before Removal of Shipping Strap Install the evaporator coil level with the drain connection to A ensure proper drainage. B To avoid damage to the plastic drain pan, minimum spacing is required between the drain pan and a furnace heat exchanger. A minimum spacing of 2" (5.1 cm) is required for a gas furnace. A minimum spacing of 4" (10.2 cm) is required for an oil-fired furnace. See "Evaporator Coil Drain Pan Clearances." Evaporator Coil Drain Pan Clearances C C. Ring seal A B A.
