– Natural Gas Manifold Pressure 3.5”W.C– LP Gas Manifold Pressure - 10”W.C.

Supply and manifold pressure taps arelocated on the gas valve body 1/8” N.P.T.and on the manifold.

Use a properly calibrated manometer gaugefor accurate gas pressure readings.

Only small variations in the gas flow shouldbe made by means of the pressure regulatoradjustment. Furnaces functioning on LP gasmust be set by means of the tank or branchsupply regulators. The furnace manifoldpressure should be set at 10” W.C. at the gascontrol valve.

To adjust the pressure regulator, remove theregulator cap and turn the adjustment screwclockwise to increase pressure orcounterclockwise to decrease pressure.Then replace the regulator cap securely.

Any necessary major changes in the gasflow rate should be made by changing thesize of the burner orifices. To change orificespuds, shut off the manual main gas valveand remove the gas manifold.

1. Remove the compressor accesspanel. Disconnect the wires to thecondenser fan motor in the control box(see wiring diagram).

2. The coil should be cleaned when it isdry. If the coil is coated with dirt or lint,vacuum it with a soft brushattachment. Be careful not to bend thecoil fins.

3. If the coil is coated with oil or grease,clean it with a mild detergent-and-water solution. Rinse the coilthoroughly with water. IMPORTANT:DDoo nnoott use excessive water pressure.Excessive water pressure can bendthe fins and tubing of the coil and leadto inadequate unit performance. Becareful not to splash water excessivelyinto unit.

4. The venturi should also be inspectedfor items of obstruction such ascollections of grass, dirt or spiderwebs. Remove any that are present.

5. Inspect the circulating air blowerwheel and motor for accumulation oflint, dirt or other obstruction and cleanit necessary. Inspect the blower motormounts and the blower housing forloose mounts or other damage. Repairor replace if necessary.

Re-assembly1. Reconnect fan motor wires per thewiring diagram attached to the back ofthe cover.

2. Close the filter control and replace theblower/evaporator coil access panels.

3. Replace the control box cover.

4. Restore electrical power to the unitand check for proper operation,especially the condenser fan motor.

REPLACEMENT PARTSContact your local distributor for acomplete parts list.

TROUBLESHOOTINGRefer to Figures 19 and 20 for determiningcause of unit problems.

WIRING DIAGRAMSFigures 21 through 28 are complete wiringdiagrams for the unit and its powersources. Also located on back ofcompressor access panel.
