INSTALLATION
Ventilation system (HRV/ERV) should be installed and balanced in accordance with its installation manual.
Furnace fan must be on when either the ventilation system (HRV/ERV) or the HEPA filtration system is oper-
ating.
A power damper is recommended to prevent backdrafting of some models of air to air changers, when in
the off or standby position. This damper will be installed between the HRV/ERV and the HEPA unit.
NOTE: Models SHR/SER 1505R, 2005R & 3005R have an automatic backdraft damper build in that acti-
vates when units are in standby position and do not need this additional damper.
All units should be checked after installation for compatibility and proper operation.
Controls Options
A "Accessory Control Contacts" device, which switches the HEPA to its on position anytime the furnace
blower is operating, is available through Fantech distributors.
