Product Overview

The Pentair UltraTemp 140 Heat/Cool Pool Heat Pump | 460959 is an energy-efficient pool and spa heating and cooling system designed to extend the swimming season and provide improved temperature control throughout the year.

Unlike a traditional gas heater, the UltraTemp heat pump transfers heat from the surrounding air into the pool water, helping reduce operating costs in suitable climates. The heat-and-cool function can also lower the water temperature during hot weather, making it an excellent choice for pools exposed to intense summer heat.

Model 460959 is the black-cabinet version of the UltraTemp 140 H/C. It features a corrosion-resistant titanium heat exchanger, digital controls, automatic defrost protection, and compatibility with Pentair automation systems.

Specifications

Warranty & Compatibility

Installation Information

Installation must be completed by qualified pool and electrical professionals. The installer must verify the required electrical service, breaker size, wire gauge, water-flow rate, plumbing arrangement, equipment-pad clearances, drainage, grounding, bonding, and available airflow.

The heat pump requires unrestricted airflow around and above the unit. Installing it in an enclosed or poorly ventilated location can reduce performance and cause operating problems.

Heating output depends on outdoor air temperature, humidity, pool size, desired water temperature, wind exposure, and whether a pool cover is used.

Confirm Before Ordering

• Confirm model number 460959.
• Verify that a heat-and-cool unit is required.
• Confirm the black cabinet is preferred.
• Verify the available electrical service.
• Confirm adequate equipment-pad clearance and airflow.
• Verify plumbing size and water-flow requirements.
• Confirm the unit is properly sized for the pool.
• Check compatibility with the existing automation system.
• Note that installation materials are not included unless stated.
• Do not confuse this model with the almond 460958 version.
• Do not confuse it with a heating-only UltraTemp model.
