Frequently Asked Questions
How does the auto pump-out work on the Namco 110 Pint Dehumidifier?
The Model P646 uses a built-in condensate pump to continuously discharge collected water through the included 50 ft. drainage hose. Unlike gravity-drain units, it can pump water upward and over distance, so you don’t need to place the unit near a floor drain or manually empty a tank. That is a real time-saver on multi-day restoration jobs. If a pump-equipped model is a priority for your fleet, browse our full dehumidifiers with pump collection for additional capacity options.
What’s the maximum operating temperature for the Namco P646 dehumidifier?
The unit is rated for a maximum operating temperature of 105°F, making it a solid choice across a wide range of job site conditions, from basements and crawl spaces to warmer commercial environments.
Does the Namco dehumidifier have a filter, and how often should it be cleaned?
Yes, the unit includes an air filter to protect the coils from dust and debris. Inspect the filter every 2 to 4 weeks during continuous operation and rinse it with warm water. Allow it to dry fully before reinstalling. A clogged filter reduces extraction efficiency; do not skip this step on long restoration jobs.
Does the Namco 110 Pint Dehumidifier include a drainage hose?
Yes, the P646 ships with a 50 ft. drainage hose for remote discharge, letting you route collected water well away from the unit itself without needing a nearby floor drain. Browse our dehumidifiers with drain hose collection for similar options.
What does the warranty cover on the Namco 110 Pint Dehumidifier?
Parts are covered under a 1-year pro-rated warranty, with the customer’s share of the cost increasing in stages after the first 90 days. Labor is covered for the first 90 days; after that, we bill labor at the prevailing hourly rate. The warranty does not cover damage caused by misuse or improper installation.
