035-15410-002-B-0404 LIMITATIONS TABLE 1 UNIT APPLICATION DATA Rated in accordance with ARI Standard 110, utilization range “A”. Below 0°F, the control system stops the compressor and allows the electric heat accessory to cycle at its standby capacity. Operation below this temperature is permissible for a short period of time when a unit is required to heat the conditioned space up to 50°F. -

035-15410-002-B-0404 LINE SIZING TABLE 4 LIQUID LINES Based on Refrigerant-22 at the nominal cooling capacity of the system, a liquid temperature of 105°F and a vapor temperature of 40°F. Since refrigerant flow rates will be a little lower at the nominal heating capacity of each system, liquid line friction loss should always be based on cooling operation. - Page 8 (29 feet x 8.0 psi/100 feet) ...2.3 psi 7 feet of 1-3/8" OD, type “L” copper tubing (horizontal) (7 feet x 2.8 psi/100 feet) ...0.2 psi Fitting*...0.5 psi Vapor Line Pressure Drop = 3.0 psi Determine the pressure drop of the fittings for each installation - DO NOT use the estimated values as shown in the above examples.

035-15410-002-B-0404 GENERAL CAUTION: Reversing valves and check valves are precise mechanical devices and will not tolerate any me- chanical abuse such as hammering. If a refrigerant system isn't properly cleaned after a compressor burn-out, scale may build up at these devices and prevent them from operating properly. - Page 14 IN ALL THREE RESET METHODS DESCRIBED ABOVE, A FIVE MINUTE TIME DELAY WILL TAKE PLACE AFTER THE RESET BEFORE THE UNIT WILL RESTART. 8. Supplemental electric heat (if installed) will be controlled by second stage TH2 of the thermostat. The supplemental electric heat circuit is controlled through low voltage termi- nals W, 60 and 66.
