Concealed/Recessed Units
Exposed panels on recessed units are 18- gauge steel construction and ship separate from the unit. Bottom panels on horizontal recessed models ship with tamperproof screw fasteners and safety chain.
Unit Finish
All cabinet parts and exposed recessed panels are cleaned, bonderized, phos-
phatized, and painted with a baked powder finish available in six decorator colors. Standard finish meets ASTM B117 specifications (salt spray test).
Fans
The aluminum fan wheels are centrifugal
Motors
All permanent split capacitor motors are run tested in assembled units. All motors have integral thermal overload protection with a maximum ambient operating temperature of 104 F and are perma- nently lubricated. Motors are capable of starting at 78 percent of rated voltage and operating at 90 percent of rated voltage on all speed settings. Motors can operate up to 10 percent over voltage.
Hot Water Coils
Hot water coils are burst tested at 450 psig (3,103 kPa) (air) and leak tested at 100 psig (690 kPa) (air under water).
Maximum main coil working pressure is 300 psig (2,069 kPa). Maximum entering water temperature is 200 F (93 C). Tubes and
Steam Coils
The steam heating coil is a
Piping Packages (Hot Water Coils Only) All piping packages are burst tested at 450 psig (3,103 kPa) (air) and leak tested at 100 psig (690 kPa) (air under water). The maximum working pressure of the interconnecting piping is 300 psig (2,069 kPa).
Piping packages are available in either basic or deluxe configurations. The deluxe package includes unions at the coil connections and a 20 mesh strainer on the supply side with a pressure rating on the strainer of up to 400 psig (2,758 kPa). The basic package does not include either unions or the strainer.
End valve options available on both the basic and deluxe piping packages include ball valves, manual circuit setters, and auto circuit setters.
Ball Valve Supply and Return
A
Ball Valve Supply, Manual Circuit Setter Return
A ball valve is provided on the supply with a manual circuit setter on the return. The manual circuit setter is a combina- tion
Ball Valve S & R, Auto Circuit Setter Return
Ball type end valves are mounted on the supply and return, with an additional auto circuit setter mounted on the return. The auto circuit setter is an automatic flow control valve that is sized to allow a specific GPM through the coil. Auto circuit setters also include two P/T plugs and have a maximum working pressure of 400 psig (2,758 kPa).
