Roof Curb Assembly Instructions

FRAME ASSEMBLY

1.Take one end piece (locking tabs) and one side piece (slots). Stand both pieces vertically on the floor or roof. See Figure 1.

2.Raise slightly the corner of the end piece (locking tabs) and mate with side piece (slots), ensuring that lower locking tab with leading edge is through slot opening. See Figure 2.

3.Push down on top edge of end piece. Ensure that all 3 of the locking tabs are feeding into each correspond- ing slot. Once both pieces are flush, the process is complete. See Figure 3.

4.Drive one spike provided into wood nailer strips at each corner. See Figure 3.

FRAME APPLICATION AND LOCATION

This roof mounting frame provides necessary support when the unit is installed. The frame can be installed directly on deck having adequate structural strength or on roof supports under deck.

SECURING THE FRAME

To ensure proper mating with unit, it is critical that mounting frame be squared to the roof, as follows:

side piece

slot for tab

end piece

1.With frame situated level in desired location on roof trusses, tack weld one corner of frame.

2.Measure frame diagonally from one corner to the opposite corner. Repeat with the remaining two cor- ners. These dimensions must be equal for the frame to be square.

3.It is extremely important to sight frame from all cor- ners to ensure that the frame is not twisted across top side. Shim frame under any low sides.

4.After frame has been squared, straightened and shimmed, weld or attach frame securely to roof.

MAX. SLOPE TOLERANCE: 1/16" per linear

foot in any direction.

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.
