SAFETY CONSIDERATIONS
Installing, starting up, and servicing ventilation equipment
can be hazardous due to system pressures, electrical compo-
nents and equipment location (roofs, elevated structures, etc.).
Only trained, qualified installers and service mechanics should
install, start up, and service this equipment.
When working on the equipment, observe precautions in the
literature and on tags, stickers, and labels attached to the
equipment. Follow all safety codes.
GENERAL
The P707-SHR1504 and P707-SHR2004 Heat Recovery
Ventilators (HRV) are used to exchange indoor stale air with
outside fresh air. The HRV unit is equipped with a special ener-
gy recovery core which transfers sensible heat with the fresh
incoming air. The cross-flow design core allows entering and
leaving airstreams to transfer heat energy without mixing.
The HRV is available in 2 sizes with airflow ranges of
150 cfm (SHR1504), and 200 cfm (SHR2004). The design of
this unit is horizontal. Special attention should be given to duct
application, balancing the HRV, and locating unit for easy
access and routine maintenance. See Table 1 and Fig. 1 for
performance data.
Table 1 — Performance Data
Before installation, always check to be sure main power to
systems are OFF. Electrical shock can cause personal
injury or death.
