Adjust measurement frequency according to the stability of performance indicator values.

Monitor temperature, disinfectant residuals, and pH frequently based on performance of water management program or Legionella performance indicators for control.

Develop or refine a WMP with the following guidelines in mind:

A comprehensive WMP allows water system operators to layer a series of complementary control measures to create environmental conditions that prevent bacterial intrusion, growth, and transmission. No single measure can ensure Legionella control.

Use a WMP to protect building operators, staff, and visitors from exposure to Legionella in potable water systems. Operation, Maintenance, and Control Limits Consider installing sampling ports throughout your water system in locations to facilitate water parameter monitoring and WMP validation.Use appropriately sized hot and cold water storage tanks fitted with recirculating pumps to maintain flow and avoid unfavorable temperature gradients.Identify water system components that speed the decay of disinfectant residuals (e.g., UV devices, water softeners, carbon filters, heaters).Recognize that low-flow and mechanically complex fixtures (e.g., electronic sensor faucets) can increase the risk of Legionella growth.

Install thermostatic mixing valves as close as possible to fixtures to prevent scalding while permitting circulating hot water temperatures above 120☏ (49☌).Eliminate sections of no- or low-water flow called dead legs.Use pipe insulation to maintain hot and cold water temperatures throughout the water system.They should be evaluated from the point at which water enters a facility system to the point where it leaves the system through a fixture or device.

The following considerations apply to hot and cold potable water systems.

Direct drive fans increase efficiency and allow for belt-less, maintenance free operation.Understanding potable water system design components is critical for Legionella control.

Modulating speed/capacity equipment that can modulate to meet the exact loads, while staying continuously operational, avoids cycling and puts less wear and tear on the system.

Up to 21.3 IEER rating, which is over 1.5x the ASHRAE 90.1-2016 IEER standard.

Optimized controls allow for system integration between all modulating components.

Modulating technologies allow for highest efficiencies at part-load conditions.

Consistent temperature is maintained, minimizing temperature swings and optimizing occupant comfort.

Variable speed components adjust heating and cooling capacity to match the required load.

Fully modulating refrigeration and hot gas reheat components deliver the exact amount of air requested at the desired temperature and humidity.

Designed with sustainability in mind, these units are built to last up to 25 years. These units help buildings conserve energy, offer precise temperature and humidity control, superior efficiency, and feature an industry-leading warranty. High quality DOAS lineup that seamlessly integrates with Rheem commercial systems.
