The Elkay 97890C is designed for direct bury installation, set in concrete to locate and align an outdoor tubular fountain before it is mounted. Installation by an authorized service person is required, in line with local plumbing and other applicable codes.
Key Installation Requirements:
- Compatible 4400, 4410, 4420, or 4430 model outdoor tubular fountain (not included)
- Concrete forms to secure the adapter (not included)
- Water inlet and drain lines roughed in to align with the adapter
- Plastic drain fittings (not included)
- Compliance with local plumbing, electrical, and other applicable codes
Important Notes Before Installing the 97890C:
- Use plastic drain fittings to electrically isolate the fountain from the building plumbing. This helps prevent electrolysis, which can cause a metallic taste or raise metal content in the water.
- Allow the concrete to cure fully before removing the flange bolts, and keep the bolts and washers for mounting the fountain.
- Always refer to the official Elkay 97890C Spec Sheet for dimensions and product details.
Basic Installation Overview:
- Thread one nut onto each of the two 3/4" rods.
- Thread the rods into the adapter cylinder and tighten the nuts firmly against it.
- Place a washer on each 3/8" bolt and install the bolts through the adapter flange, fully threaded in.
- Secure the adapter in the concrete forms, aligned with the water inlet, drain line, and fountain orientation.
- After the concrete cures, remove the flange bolts and washers.
- Mount the fountain to the adapter with the bolts and washers, following the fountain's own installation instructions.
