Specifications
Warnings and Disclaimers
- Installation Height: To comply with [NEC standards](https://www.intermatic.com), the box must be installed at least 4 inches above the ground/pool deck level and 8 inches above the maximum pool water level.
- Drowning Risk: All electrical connections must be performed by a [licensed electrician](https://www.intermatic.com). Improperly grounded lights can cause electric shock or electrocution in the water.
- Conduit Integrity: Use only approved PVC solvent cement for conduit connections to ensure the system remains watertight. Leaking conduits can lead to short circuits and GFCI tripping.
- Load Limit: Do not exceed the maximum number of permitted wires/lights. Overcrowding the box can prevent the gasket from sealing properly, allowing moisture and insects to enter.
- Service Loop: Leave at least 3-4 feet of extra light cord (coiled) inside the [PJB2175 spacious interior](https://www.intermatic.com). This allows you to pull the light fixture onto the deck for bulb/LED changes without draining the pool.
- Gasket Maintenance: Every time you open the lid for maintenance, inspect the rubber gasket for cracks. Applying a tiny amount of [silicone-based lubricant](https://www.intermatic.com) will extend its life and ensure a tighter seal.
- Wall Mounting: If you aren't mounting on a stake, the box features back-entry mounting holes. Ensure you use the provided sealing washers to maintain the watertight rating.
- Future-Proofing: Even if you only have one light now, using a dual-port box like the PJB2175 makes it easy to add a [second spa light](https://www.intermatic.com) later without re-digging your electrical trench.
