Energy Recovery Ventilator
Models IK008 to IK018
(3/4 - 1½ ton units)
Outside air fan is designed to provide 50 cfm (23 lps) of
outside air against an external static pressure of 0.15"
(40 pa). The exhaust air fan exhausts 50 cfm (23 lps)
against a static pressure of 0.25”(65 pa).
Energy Recovery Ventilator
Models HK020 to HK036
(1¾ - 3 ton units)
Outside air fan is designed to provide 100 cfm (47 lps) of
outside air against an external static pressure of .15"
(40 pa). The exhaust air fan exhausts 100 cfm (47 lps)
against a static pressure of 0.25”(65 pa).
Core Media
Fan and Core sections are removable. The membrane is
constructed from a composite of polymer material that
allows heat and water vapor to transfer from one air
stream to another while preventing cross contamination.
Defrost
The outside air fan is turned off during the defrost cycle.
The defrost cycle is temperature dependent and activated
with any indication of icing.
The membrane contains Microban anti-microbial
protection which will eliminate mold and bacteria that
reach this surface. The sensible efficiency shall be no
less than 80%.
Energy Recovery Ventilators (ERV)
Sequence of Operation
1. The Vertical Stacked main supply fan must be
operating in order for the ERV apparatus to operate
4. The ERV control switch must be “ON” to provide fresh
air introduction
2. ERV fans will be enabled to operate:
a) On a call for heating from the thermostat
b) On a call for cooling from the thermostat
c) When thermostat fan selector switch is placed in
the “ON” mode
d) When a field mounted 24v remote control switch is
closed
5. The backdraft damper on the fresh air fan will open
when the fresh air fan is operational
3. The unit cabinet has a built in bypass relief damper to
allow the toilet exhaust fan to exhaust if the unit and/
or ERV fans are “OFF”.
6. All fans will run under normal operation
7. The defrost sensor will detect a frost build up on the
heat exchanger and will terminate the operation of the
fresh air fan until the frost clears
