Dial 4405 Pump Installation and Start-up Kit for Evaporative Coolers

Product Description

The Dial 4405 Pump Installation and Start-Up Kit is a complete accessory package designed for use with evaporative cooler pumps, both new and existing units. Evaporative coolers, also known as swamp coolers, rely on a functioning pump to circulate water evenly across the cooling pads. When the pump system is properly installed and maintained, water distribution stays consistent, pads remain uniformly saturated, and the unit delivers maximum cooling output with minimal energy use. This kit gives HVAC technicians and homeowners everything needed to complete a proper pump installation in a single package, eliminating the need to source individual parts separately.

The Dial 4405 includes a 1/4-inch float valve to regulate water levels inside the cooler reservoir. It also comes with a water distributor adapter, a 5-foot length of 1/2-inch pump hose, a pump hose restrictor, a round-formed basket strainer, two hose ring clamps, a plastic drain and overflow pipe, and a full set of installation instructions. Each component is manufactured from materials built to handle the continuous moisture exposure and temperature cycling common in evaporative cooling systems. Proper water flow control through the restrictor and float valve helps prevent overflow and reduces wear on the pump over time. The basket strainer protects the pump inlet from debris, extending service life and reducing maintenance calls. This kit suits technicians performing seasonal start-up service, pump replacements, or system retrofits on residential and light commercial evaporative coolers. Having all parts in one kit simplifies job planning and reduces callbacks. The included instructions support straightforward installation for both experienced HVAC professionals and skilled do-it-yourself users.
