The Elkay EZSTLDDLC is a wall-mount bi-level non-refrigerated drinking fountain designed for on-wall indoor installation, and it ships in one box. Professional installation by a licensed plumber is strongly recommended to ensure proper water supply, drainage, and electrical connections.
Key Installation Requirements:
- Wall-mounted (on-wall), indoor installation only
- 115V/60Hz GFCI-protected duplex outlet in a recessed box
- 3/8" O.D. unplated copper water supply with shut-off (not included), up to 3" out from the wall
- 20 to 105 psi supply line pressure
- 1-1/2" trap (not included) and 1-1/2" nominal drain, with the drain stub 2" out from the wall
Important Notes Before Installing the EZSTLDDLC:
- The unit does not include the shut-off or 1-1/2" trap. These must be supplied separately by the installer.
- A minimum of 40 psi supply line pressure is required for adequate stream height when both bubblers are used at the same time.
- Choose the standard or alternate rough-in before mounting, since this sets which side is high and which is low.
- For a children's ADA installation, reduce the height by 3 inches.
- A dedicated circuit with load protection sized for 20 amps is highly recommended.
- If the wall cannot adequately support the unit, add a fixture support carrier such as the MLP200 In-Wall Carrier.
- Always refer to the official Elkay EZSTLDDLC Spec Sheet for compliance information and product details.
Basic Installation Overview:
- Confirm the wall can support the unit (approx. 46 lbs shipping weight).
- Remove the hanger bracket from the back of the unit by removing one screw, then anchor it securely to the wall using all six 1/4" mounting holes.
- Hang the unit on the bracket, making sure the bracket engages properly in the slots on the back.
- Remove the four screws holding the lower front panel, then pull the panel straight down and set it aside.
- Connect the water supply according to local codes.
- Install the trap on the waste line and tighten the slip nut securely.
- Plug in the unit, since it must have electrical power for water to flow.
- Check for leaks and test both bubblers. The stream height is factory set at 35 psi, so adjust it if your supply pressure varies greatly.
- Replace the front panel and all four screws.
