airflow take precedence over airflow values specified in manufacturer installation instructions or product literature.
In Appendix C to Subpart R, revise section 3.3.7 which specifies modifications to AHRI 12502009 to read:

3.3.7. For unit coolers tested alone, calculate AWEF on the basis that walkin box load is equal to half of the system net capacity, without variation according to high and low load periods, and with EER set according to tested evaporator capacity, as follows:
For Unit Coolers Tested Alone:

The net capacity, qmix,evap, is determined from the test data for the unit cooler at the 38 F suction dewpoint.

3 Representations. LRC Coil may not make representations about the efficiency of a basic model listed in paragraph 1 for compliance, marketing, or other purposes unless that basic model has been tested in accordance with the provisions set forth in this alternate test procedure and such representations fairly disclose the results of such testing.
4 This Interim Waiver Order shall remain in effect according to the provisions of 10 CFR 431.401.
5 This Interim Waiver Order is issued on the condition that the statements and representations provided by LRC Coil are valid. If LRC Coil makes any modifications to the controls or configurations of a basic model subject to this Interim Waiver Order, such

modifications will render the waiver invalid with respect to that basic model, and LRC Coil will either be required to use the current Federal test method or submit a new application for a test procedure waiver. DOE may rescind or modify this waiver at any time if it determines the factual basis underlying the petition for the Interim Waiver Order is incorrect, or the results from the alternate test procedure are unrepresentative of a basic models true energy consumption characteristics. 10
CFR 431.401k1. Likewise, LRC Coil may request that DOE rescind or modify the Interim Waiver Order if LRC Coil discovers an error in the information provided to DOE as part of its petition, determines that the interim waiver is no longer needed, or for other appropriate reasons. 10 CFR 431.401k2.

6 Issuance of this Interim Waiver Order does not release LRC Coil from the applicable requirements set forth at 10 CFR part 429.
DOE makes decisions on waivers and interim waivers for only those basic models specifically set out in the petition, not future models that may be manufactured by the petitioner. LRC
Coil may submit a new or amended petition for waiver and request for grant of interim waiver, as appropriate, for additional basic models of Walk-in Cooler Refrigeration Systems.
Alternatively, if appropriate, LRC Coil may request that DOE extend the scope of a waiver or an interim waiver to include additional basic models employing the same technology as the basic models set forth in the original
