High Altitude Derate - Daikin DCG036XXX1DXXX Technical Manual

PRODUCT DESIGN
High Altitude Derate - U.S. Installations Only
MPORTANT NOTE: The gas/electric units naturally derate with altitude. Do not attempt to increase the firing rate by
I
changing orifices or increasing the manifold pressure. This can cause poor combustion and equipment failure. At all
altitudes, the manifold pressure 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 temperature rise must be within the range listed on the unit nameplate. Refer to the
Installation Manual provided with the LP kit for conversion from natural gas to propane gas and for altitude adjustments.
When this package unit is installed at high altitude, the appropriate High Altitude orifice kit may be installed. As altitude
increases, there is a natural reduction in the density of both the gas fuel and combustion air. This kit will provide the proper
design certified input rate within the specified altitude range. High altitude kits are not approved for use in Canada. For
installations above 2,000 feet, use kit HA-02. The HA-02 kit is used for both Natural and LP gas at high altitudes.
For DCG036045, use LPT-00A propane conversion kit for propane conversions at altitudes below 2000 feet. Natural gas
installations below 2000 feet do not require a kit. For all other 3, 4 and 5 ton models, use LPM-05.
For propane conversion above 2000 feet, high altitude kit HA-02 is required in addition to propane conversion kit LPT-00A
or LPM-05.
