TRANSPORTATION DAMAGE
Check the carton upon arrival for external damage. If damage is found, a request for inspection by carrier agent should be made in writing immediately.
Carefully inspect the unit for damage including damage to the cabinetry. Any bolts or screws which may have loosened in transit must be
1.Make notation on delivery receipt of any visible damage to shipment or container.
2.Notify carrier promptly and request an inspection.
3.In case of concealed damage, carrier should be notified as soon as
4.File the claim with the following supporting documents:
a.Original Bill of Lading, certified copy, or indemnity bond.
b.Original paid freight bill or indemnity in lieu thereof.
c.Original invoice or certified copy thereof, showing trade and other discounts or reductions.
d.Copy of the inspection report issued by carrier representative at the time damage is reported to the carrier. The carrier is responsible for making prompt inspection of damage and for a thorough investigation of each claim. The distributor or manufacturer will not accept claims from dealers for transportation damage.
NOTE: When inspecting the unit for transportation damage, remove all packaging materials. Recycle or dispose of the packaging ma- terial according to local codes.
RIGGING DETAILS
WARNING
TO PREVENT PROPERTY DAMAGE, THE UNIT SHOULD REMAIN IN AN UPRIGHT POSITION DURING ALL RIGGING AND MOVING OPERATIONS. TO FACILITATE LIFTING AND MOVING WHEN A CRANE IS USED, PLACE THE UNIT IN AN ADEQUATE CABLE SLING.
Important: If using bottom discharge with roof curb, ductwork should be attached to the curb prior to installing the unit. Ductwork dimen- sions are shown in roof curb installation instructions.
Refer to the Roof Curb Installation Instructions for proper curb in- stallation. Curbing must be installed in compliance with the National Roofing Contractors Association Manual.
Lower unit carefully onto roof mounting curb. While rigging unit, center of gravity will cause condenser end to be lower than supply air end.

GAS PIPING
IMPORTANT NOTE: This unit is factory set to operate on natural gas at the altitudes shown on the rating plate.
WARNING
TO AVOID PROPERTY DAMAGE, PERSONAL INJURY OR DEATH WHEN EITHER USING PROPANE GAS ALONE OR AT HIGHER ALTITUDES, OBTAIN AND INSTALL THE PROPER CONVERSION KIT(S). FAILURE TO DO SO CAN RESULT IN UNSATISFACTORY OPERATION AND/OR EQUIPMENT DAMAGE. HIGH ALTITUDE KITS ARE FOR U.S. INSTALLATIONS ONLY AND ARE NOT APPROVED FOR USE IN CANADA.
The rating plate is stamped with the model number, type of gas and gas input rating. Make sure the unit is equipped to operate on the type of gas available. Conversion to LP gas is permitted with the use of the factory authorized conversion kit
| Inlet Gas Pressure |
Natural | Min. 5.0" W.C., Max. 10.0" W.C. |
Propane | Min. 11.0" W.C., Max. 13.0" W.C. |
Inlet Gas Pressure Must Not Exceed the Maximum Value Shown in Table Above.
The minimum supply pressure should not vary from that shown in the table above because this could prevent the unit from having dependable ignition. In addition, gas input to the burners must not exceed the rated input shown on the rating plate. Overfiring of the unit could result in premature heat exchanger failure.
HIGH ALTITUDE DERATE (U.S. INSTALLATIONS ONLY)
IMPORTANT NOTE: The gas/electric units naturally derate with al- titude. Do not attempt to increase the firing rate by changing ori- fices or increasing the manifold pressure. This can cause poor com- bustion and equipment failure. At all altitudes, the manifold pres- sure must be within 0.3 inches W.C. of that listed on the nameplate for the fuel used. At all altitudes and with either fuel, the air tempera- ture rise must be within the range listed on the unit nameplate.
Refer to the Installation Manual provided with the LP kit for conver- sion from natural gas to propane gas and for altitude adjustments.
PIPING
IMPORTANT NOTE: To avoid possible unsatisfactory operation or equipment damage due to under firing of equipment, do not under- size the natural/propane gas piping from the meter/tank to the unit. When sizing a trunk line, include all appliances on that line that could be operated simultaneously.
The rating plate is stamped with the model number, type of gas and gas input rating. Make sure the unit is equipped to operate on the type of gas available. The gas line installation must comply with local codes, or in the absence of local codes, with the latest edition of the National Fuel Gas Code NFPA 54/ANSI Z223.1.
