R. Hydronic Unit Heaters:

1. Heating Coil: Constructed of seamless copper pressure tubing mechanically bonded to the collars of aluminum fins. Tubes brazed to steel headers and mounted to provide for expansion. Coils guaranteed for safe operation at steam or hot water pressure up to 150 pounds per square inch, or factory tested at 500 PSIG hydrostatic and 200 PSIG steam pressure.

2. Fans & Motors: Large face area blade style of aluminum and mechanically fastened to steel hubs or non-overloading fan wheel design and direct connected to motors. Fans factory tested and dynamically balanced. Fan blades protected with a fan guard of corrosion resistant metal. Guard may serve as motor mounting bracket. Motors UL Listed, thermal overload protected, and rated continuous duty by NEMA standards, but capable of operation in 104 degrees F.

ambient temperature and permanently lubricated. Motors resiliently mounted to prevent vibration transmission to the building and heat shielded from the heating coil. Motor controls manufacturer's standard for starting and limit control.

3. Horizontal Style Casing: Fabricated from 20 gauge steel minimum with internal reinforcing and threaded hanger rods or pipes for unit suspension mounting.

Casing back panel formed into a fan venturi. Casing air discharge fitted with horizontal one-way adjustable air delivery blades. Casing finished inside and out with baked-on primer and enamel after cleaning, bonderizing, phosphatizing treatments on the base metals. Final enamel in manufacturer's standard color.

4. Vertical Style Casing: Fabricated from 20 gauge steel minimum with internal reinforcing and threaded hanger rods or pipes for unit suspension mounting. Fan venturi formed in casing bottom and casing top depressed for motor and fan location. Casing air discharge fitted with down-flow two-way spread pattern air delivery blades. Casing finished inside and out with baked-on primer and enamel after cleaning, bonderizing, phosphatizing treatments on the base metals. Final enamel in manufacturer's standard color.

5. Controls: Thermostat provided by automatic temperature control installer.

Thermostat shall cycle the fan on call for heat.

6. Electrical: Provide and install local disconnect switch for each unit.
