2 AIR HANDLER FEATURES ALL MODELS Suitable for use with R22 and R410a Rifled Copper Tubing Patented lance fin design Ratings in conformity with ARI standard 210 ETL Listed Available voltage 220/1/50 Hz High efficiency 3-speed motors 40 VA control voltage transformer Dynamically balanced blowers for quiet vibration free operation Refrigerant connections are 3/8" ODF liquid and 3/4" ODF (12 36) or 7/8" ODF (31, 37 60) suction Dual 3/4" FPT condensate drains Drain pans are molded of corrosion proof engineering polymer Florator, non-bleed A/C or HP expansion valve also available as a kit for field installation (all screw-on connections) BC (SLANT COIL) Choice of left or right drain and refrigerant connections during installation. This option makes it possible to have the return air enter the left or right side in addition to the bottom Filter rack with filter built into every air handler Electric heat available factory installed or in kit form for field installation. Plug in connections simplify installation of kits heating coils available factory installed in 2 or 3 rows (with or without pump). Also available as a kit to add to no heat models Cabinet constructed of pre-painted heavy gauge galvanized steel to prevent corrosion. Lined with high quality 1" mat faced insulation Available from factory as upflow or upflow / horizontal. Field installed horizontal drain pan kit is also available Circuit breaker optional factory installed or as kit, 5 10 kw. Standard on 12,5 kw and higher. All field installed kits come with thorough, easy to follow instructions All air handlers are top handling (basiloid) packaged with bar coding and full description label. Electrical connections can be made on top or right side Fan time delay available as kit or factory installed Easy to follow wiring diagrams on all air handlers Easily converted to counterflow with kit All coils are individually pressure tested at 450 PSI, then pressurized and sealed BC (A-COIL) Choice of left or right drain connections during installation Filter rack with filter built into every air handler Electric heat available factory installed or in kit form for field installation. Plug in connections simplify installation of kits heating coils available factory installed in 3 or 4 rows (with or without pump). Also available as a kit to add to no heat models ADDITIONAL FEATURES FOR ALL WATER HEAT MODELS Easy to replace water coil. Remove one screw and slide out Heating blower time delay standard on all models On models without a pump there is ample room inside cabinet for mounting aquastat if desired. This provides a clean looking installation Separate set of contacts for interfacing with external components (i.e burner relay, pump relay or zone valve) Easy to follow wiring diagrams for connecting to popular zoning controls Low water pressure drop through heating coil for excellent heating performance Easy to adjust blower speeds for fine tuning customer comfort Blower door safety switch Large water connections out the top. 7/8" ODF 1 ½ - 3 ton and 1 1/8" ODF 3 ½ - 5 ton models 2
