Existing evaporator coil – If the existing evaporator coil may be re-used, check with the coil manufacturer to verify the coil construction is suitable for operation with the higher pressures of PuronR (R-410A). Also determine if the existing TXV valve is compatible with R-410A, replace if necessary. The minimum factory test pressure rating must be 250 psig (1725 kPa). Existing coil will need to be purged with Nitrogen to remove as much mineral oil as possible to eliminate cross contamination of
Installation of this product should follow all manufacturer’s refrigerant charging and air flow instructions. Failure to confirm proper charge and air flow may reduce energy efficiency and shorten equipment life. 558J558J TABLE OF CONTENTS PAGE PAGE FEATURES AND BENEFITS .................... 3 MODEL NUMBER NOMENCLATURE ............ 4 FACTORY OPTIONS & ACCESSORIES ........... 5 ARI CAPACITY RATING ....................... 8 SOUNDPERFORMANCE ...................... 10 PHYSICALDATA ..................
The same equation can be used to determine the occupied or maximum ventilation rate to the building. For example, an output of 3.6 volts to the actuator provides a base ventilation rate of 5% and an output of 6.7 volts provides the maximum ventilation rate of 20% (or base plus 15 cfm per person). Use Fig. 38 to determine the maximum setting of the CO2 sensor. For example, a 1100 ppm set point relates to a 15 cfm per person design. Use the 1100 ppm curve on Fig. 38 to find the point when the CO2

Only trained and qualified service personnel should install or service air conditioning equipment. Untrained personnel can perform basic maintenance, such as cleaning and replacing filters. All other operations should be performed by trained service personnel. When working on air conditioning equipment, observe precautions in literature, tags, and labels attached to unit. Follow all safety codes. Wear safety glasses and work gloves. Use quenching cloth for brazing operations. Have fire extingu

Pay particular attention to high- and low-voltage wiring of sequencers. 2. Check plug wiring to mdee sure that it is wired correctly, 3. Check voltage to sequencer. Sequencer number 1 receives a 24-vac signal. If it is receiving correct voltage, check to see if sequencer is closing. If sequencer is not closing but is -10- '14/2008/THU 03:47 UTC TECH PUB FAX No. 317 240 5662 P. 01 TABLE 3—MALE/FEMALE QUICK-CONNECT TERMINALS SIZE FEMALE SIZE MALE DESCRIPTION 0.250 X 0.032 М2 Motor line v
