The Integrated HVAC System

WARNING: The 2500 is a quiet, efficient, low pressure system. Special care and attention should be given if connecting this unit to any other air handler that may draw more air than the 2500 is designed to accommodate.

The HRV has become an integral component of the HVAC system. Figure 4 shows an HRV unit provid- ing fresh air directly to the return air plenum of a Rooftop heat/cool unit.

Many buildings have a ceiling return air plenum as in Figure 5. Fresh air from the HRV can be intro- duced directly into the ceiling space near the air handler’s intake.

In installations where it is satisfactory to provide general exhaust from the space, the air to be exhausted may be taken directly from the return air plenum to the HRV as it is drawn back to the air handler. Fresh air supplied by the HRV is then intro- duced directly into the return air plenum but at a location closer to the air handler. The air handler would have a constant running blower to effectively distribute the fresh air and remove the stale air. Balancing dampers would be located in both the HRV supply and exhaust ducts between the return air plenum and the HRV.

Electrical Connections

System is 208/230V, 1 phase, 60 Hz. This unit meets all local codes and requirements.

It is STRONGLY recommended that an electrical disconnect be installed prior to the HRV, and that it is turned off and locked out before servicing the unit.

All electrical connections should be made by a qualified electrician.

Two (2) knock-outs are provided. One is to be used for line voltage, and the other one for 24V control wires.

Maintenance

As with any mechanical system, a dedicated maintenance program will prolong the life of the equipment, and maintain its optimum performance.

We recommend at least two (2) full inspections and cleanings per year under normal operating conditions, and more if circumstances warrant it.

Service should include:

Cleaning of screens protecting outside hoods.

Cleaning of core.

To access core, remove service panels and slide core halfway out. Wash core protruding from cabinet with water and/or a mild cleaning solution. Push core through to the other side of

the cabinet and repeat procedure to clean the other side of the core. In many cases, only a vacuuming of the core surface is required.

Inspect filters and replace as necessary.

Wipe down drain pans and inside of cabinet, using a mild disinfectant.

Ensure condensate drain has free flow of moisture.

Inspect blowers and electrical panel.

Confirm operation.

2500EFD, 2500IFD specifications

The Lifebreath 2500EFD and 2500IFD are advanced energy recovery ventilation units designed to enhance indoor air quality while maximizing energy efficiency. These systems are particularly beneficial for residential and commercial structures, offering a sustainable solution to manage indoor environments.

One of the standout features of the Lifebreath 2500 series is its Energy Recovery Ventilator (ERV) technology. This innovative system allows for the transfer of heat and moisture between the incoming and outgoing air streams. As a result, during winter months, the ERV preconditions the incoming cold air with the warmth of the outgoing air, helping to maintain a comfortable indoor temperature without excessive energy expenditure. Conversely, during summer, it helps to draw the humidity out of the incoming air, leading to a more comfortable living space.

The Lifebreath 2500EFD model is designed with a direct drive motor that operates quietly and efficiently, providing superior performance with minimal maintenance. The high-efficiency filter systems ensure that the air circulated indoors is free of dust, pollen, and other airborne contaminants, significantly improving the overall air quality. Both models also incorporate a digital control system, allowing for precise adjustments and easy monitoring of indoor air parameters.

Another significant characteristic of the Lifebreath 2500IFD is its integrated filtration technology. It features MERV 8 filters that capture fine particles, effectively reducing allergens and improving health for occupants. The unit runs quietly, ensuring that it does not disrupt daily activities while providing constant ventilation.

The Lifebreath units are also built with durability in mind. Constructed from robust materials, they are designed to withstand various environmental conditions while ensuring longevity. The compact design makes them suitable for both new constructions and retrofitting existing spaces, making them versatile solutions for improving ventilation in diverse building types.

In summary, the Lifebreath 2500EFD and 2500IFD systems combine advanced energy recovery technology with efficient air filtration, quiet operation, and a user-friendly control system. By prioritizing indoor air quality and energy efficiency, these ventilation units are essential tools for creating healthier, more comfortable living and working environments.
