Step 1: Confirm Instant Hot Is the Right Technology
American Standard water dispensers in this category are instant hot units only -- they deliver boiling-range water for tea, instant cooking, and blanching. If you need chilled filtered water, American Standard does not manufacture a cooler or chilled dispenser; you would need a separate countertop filter unit from another brand. If you need both hot and cold at the same location, pair an American Standard instant hot dispenser with a separate Brita countertop gravity filter or a PUR dispenser for cold filtered water.
Step 2: Choose Between 1650W and 1500W Models
The 4433700.002 at 1650W heats water faster and recovers more quickly between draws. At 200F maximum output, it reaches a slightly higher temperature ceiling than the 1500W AS-1064 at 195F. For a household of 1-3 people with low-volume demand, the AS-1064 at 1500W performs identically in practice -- the 150W difference is only perceptible under continuous high-volume draw. Households of 4-6 heavy users, or users who need the hottest possible water for specific cooking applications, should invest in the 4433700.002.
Step 3: Match Faucet Finish to Your Kitchen Suite
American Standard offers the 4433700 dispenser in Polished Chrome (002), Brushed Nickel (295), and Stainless (4933750.002 suffix). If your kitchen features the American Standard Edgerton or Colony main faucet in Polished Chrome, the 4433700.002 matches. Brushed Nickel (295) pairs with the American Standard Townsend and Beale faucet lines. American Standard finish codes are consistent across the kitchen faucet and dispenser lines, making cross-referencing straightforward using the 3-digit suffix.
Step 4: Measure Under-Sink Space for the Tank
The American Standard 4433700 tank is 13 inches tall and 7 inches in diameter. Clearance requirement is 15 inches vertical to allow for the supply line connection at the top of the tank. Measure from the bottom of your under-sink cabinet to the lowest point of the sink basin to confirm clearance. If you have a garbage disposal installed, ensure the tank can be positioned away from the disposal motor -- the 1650W element generates heat that can accelerate disposal motor wear if they are in direct contact.
Step 5: Verify Electrical Supply
The 4433700.002 at 1650W draws 13.75A at 120V -- higher than the 12.5A draw of 1500W competitors. A standard 15A circuit has only 1.25A headroom when the element is cycling at full wattage. American Standard recommends a dedicated 15A or 20A circuit for the 1650W model to prevent nuisance GFCI tripping when other kitchen appliances are operating on the same circuit. If your under-sink outlet is shared with the garbage disposal, add a dedicated circuit before installation.
