3、ough 10.7c for Operating Modes D and E change “Table 10.8” to “None”. 31 Table 10.5c Single Capacity Direct GeoExchange Systems. In the Required/Optional column of Table 10.5c for Operating Modes D and E change “Conditional/Optional (F)” to “Conditional/Optional (D).” 37 Sections 10.8.1.2.1 and 10.8

4、.1.3. Renumber Section 10.8.1.2.1 as 10.8.1.3 and renumber the current Section 10.8.1.3 as 10.8.1.4 as shown below. (Note: Additions are shown in underline and deletions are shown in strikethrough.) 10.8.1.3 10.8.1.2.1 A water draw is imposed until the appliance initiates water heating, either from

5、a resistive element or refrigerant-to-water heat exchange. A draw of not less than 42 L (or 41 kg) 11 gal (or 90 lb) shall be imposed. Water shall be removed at a rate of 11.4 1.0L/s (3.0 0.25 gpm) while the make-up water temperature is maintained within 14.4C 1.1C (58F 2F). Once water heating is in

6、itiated, or 42 L (or 41 kg) 11 gal (or 90 lb) has been drawn, the water draw is terminated, and the water heater is allowed to fully recover. 10.8.1.4 10.8.1.3 Beginning 10 minutes (minutes) after the water heater is fully recovered, a series of water draws, at a rate of 11.4 1.0L/s (3.0 0.25 gpm) w

(M) Test required if maximum compressor speed in heating exceeds the maximum compressor speed in cooling, see Section 11.8.2.2 for explanation. (N) Compressor speeds k = 2 for Mode B do not have to be the same as for k = 2 Mode A.
