TEMPERATURE RISE Temperature rise must be within the range specified on the unit rating plate. An incorrect temperature rise may result in condensing in or overheating of the heat exchanger. An airflow and temperature rise table is provided in the Specifi- cation Sheet applicable to your model. Determine and adjust temperature rise as follows: 1. Operate furnace with burners firing for approximately ten minutes. Ensure all registers are open and all duct dampers are in their final (fully or partially open) position. 2. Place thermometers in the return and supply ducts as close to the furnace as possible. Thermometers must not be influenced by radiant heat by being able to "see"the heat exchanger. 33 AIRFLOW TABLE LOW STAGE COOLING AIFLOW HIGH STAGE COOLING AIFLOW THERMOSTAT EXTERNAL STATIC

Make final charge adjustments in the cooling cycle. Ensure the charge label has been filled out when final charging is complete. Follow directions in the System Startup section. A final leak test is recommended before leaving the site of installation. When servicing is complete, the red valve caps that are supplied on the valves must be reinstalled finger-tight on the liquid valve, vapor valve, and access port. NOTE: Maximum refrigerant charge permissible in the system can be found on the Evaporator serial plate. System Service and Decommissioning Should repairs requiring recovery of the refrigerant become necessary, special considerations must be made when breaking into systems with flammable refrigerants. These repairs shall only be performed by qualified service person- nel and in compliance with local and national regulations. The refrigerant charge shall only be recovered into a cyl- inder labeled for use with R-32. Ensure that the refrigerant cylinder(s) are capable of holding the total system charge. Cylinders shall be complete with a pressure-relief valve and associated shut-off valves in good working order. Empty recovery cylinders are evacuated and, if possible, cooled before recovery occurs.A set of calibrated weighing scales shall be available and in good working order. Hoses shall be complete with leak-free disconnect couplings and in good condition. All best practices for refrigerant recovery must be followed, including use of a recovery machine designated safe for use with A2L refrigerants. Isolate the system electrically prior to recovery. Ensure that all personal protective equip- ment is being applied correctly. Ensure that the recovery process is supervised at all times by the qualified servicer. Situate the R-32 cylinder on the scale before recovery takes place. Start the recovery machine and operate in accordance with its instructions. Do not overfill cylinders by more than 80%volume of its allowed liquid charge. Should electrical components need to be replaced, ensure that the original equipment manufacturer's part or equiva- lent is used. Markings and warnings on the unit shall continue to be visible and legible after installation and service. Correct any markings and warnings that are made illegible. When decommissioning a system, all previously mentioned precautions regarding safe refrigerant handling must be fol- lowed.Recovered refrigerant shall not be charged into another refrigerating system unless it has been cleaned and checked. Equipment must be labelled, dated, and signed stating that it has been decommissioned and emptied of refrigerant. 12 Troubleshooting Information System Complaint No Cooling Unsatisfactory Cooling/Heating Operating Pressures rn r � rn E m p C @ C O POSSIBLE CAUSE 2 2N g g t C C @ > ` C ° r r _ w E o a) o Test Method DOTS IN ANALYSIS 11 = N o N o N `c E o GUIDE INDICATE 2 y o 0 o C o' o ° c° Remedy 3 o a "POSSIBLE CAUSE" y N 0 o 3 c 3 3 �, o w L o a 0 3 O w w 2 c N y w a y n d c V C c O m h — = o. c a 3 a N ac 2 — 2 m 3 5v+ Lcoa306 cc E Eo c m E a) a N caa cpNEE Caa NCCOT O O > O O a) O >R . w0 1 to0 1 Power Failure • 1 1 1 1 Test Voltage Blown Fuse • • a. .
