Operation Instructions | Installation Tips |
The LIFEBREATH 2500 series HRV is designed tobe operated continuously or intermittently to meet the requirements of the application.
Continuous Operation
For continuous operation, a simple jumper across the ON/OFF and COMMON jumper terminals is needed. HIGH/LOW speed selection requires another jumper across HIGH/LOW and COMMON; select as required (see below and wiring diagram).
T3 - On/Off
ON/OFF
T2 - High/Low
HIGH/LOW
T1 - Common
Low
Internittent Operation
Due to variance in the times in which buildings are occupied and equipment or machinery operated, intermittent ventilation may be the preferred method.
Dry contacts located inside the electrical panel enable this unit to turn ON and OFF, and/or jump between HIGH and LOW speeds when optional low voltage controls are connected (see above and pg. 9).
Optional Remote Controls
Basic controls such as dehumidistats, mechanical crank timers,
1.Whichever method is chosen to operate the 2500, keep in mind that
To achieve optimum performance from the 2500, the desired ventilation rate (speed of the system) should be reached before the
contaminant to be removed has reached its maximum.
EXAMPLE: A bingo hall opening at 7:00PM that is sized for 5000 cfm should have at least this amount of air exchange by that time. If the unit is not turned on or set to its designated speed until after the con- taminant has reached an uncomfortable level, then it may result in a number of hours passing before the system could catch up.
2.It is highly recommended that back draft dampers be installed in the supply and exhaust duct work to the outside, to prevent air from entering in through the HRV when the unit is off. Failure to install back draft dampers may result in damage to HVAC equipment and/or other building components.
