*** IMPORTANT ***
For safe and satisfactory operation, please read the following
instructions before installing. Keep for future reference.
Introduction:
The IQ550BFF has been designed to provide outside ventilation air flow through a computer
or electronic equipment enclosure in the event of a power outage, air conditioner failure or if
the thermostat (or other sensing device) reaches its setpoint.
Unpacking Inspection:
What to look for: Damage to the shipping container.
If the shipping container has been damaged or marred in any way, carefully remove the
IQ550BFF and inspect it for any damage that may have occurred during shipping. Check for
scratches, dents, or sounds indicating loose components, or any other irregularities. Any
evidence of damage should be recorded on the freight bill. The freight carrier’s claim
procedure should be followed. Ice Qube Inc. cannot accept responsibility for damages
which occur during shipping.
Preparing the Enclosure:
A few modifications must be made to the enclosure to provide adequate air flow and
insure a secure installation.
1. Determine the location of the IQ550BFF on the enclosure.
***Caution ***
Be sure the weight of the system will not cause the enclosure to become unbalanced
causing bodily harm or injury. For units mounted on enclosure doors, be sure the
hinges will support the weight of the Ice Qube system. Refer to system specifications
for model weights.
2. Using the cutout drawing as a reference, make an opening on the enclosure surface
for intake and exhaust air, along with the holes for the mounting hardware. The
IQ550BFF should be mounted in a vertical position towards the top of the enclosure.
Air flow should not be restricted by components in the enclosure or the surrounding
ambient.
3. Verify the factory installed gasket material is in place. Slide the two (2) mounting studs
through thematching holes in the enclosure and check to seethat all holesare aligned.
4. Mount the IQ550BFF onto the enclosure using the nuts and bolts provided. Check to
be sure all nuts have been tightened securely and the gasket material is in place.
Compress the gasket to half the thickness of the gasket to form a seal.

5. Connect the IQ550BFF to power
5.1 Dual voltage models –
Connect the IQ550BFF AC power cord to a properly grounded receptacle outlet
with sufficient electricalcapacity (extension cords are not recommended). Then,
connect the IQ550BFF DC power cord to a DC power source. After both the
AC and DC power connections have been made, mount the thermostat or other
sensing device (not provided) in an appropriate monitoring location.
5.2 Single voltage AC models –
Connect the IQ550BFF AC power cord to a properly grounded receptacle outlet
with sufficient electrical capacity (extension cords are not recommended). After
the AC power connection has been made, mount the thermostat or other
sensing device (not provided) in an appropriate monitoring location.
5.3 Single voltage DC models –
Connect the IQ550BFF DC power cord to a DC power source. After the AC
power connection has been made, mount the thermostat or other sensing
device (not provided) in an appropriate monitoring location.
6. Although the IQ550BFF has been factory tested, it is recommended that it be checked
to confirm it is operational. Please see sequence of operation section.
6.1 Dual voltage models –
Disconnect the AC power supply. The fan should immediately start to operate and
the dampers will move to the open position.
6.2 Single voltage models –
Set the thermostat to a temperature lower than the ambient air temperature. The
fan should immediately start to operate and the dampers will move to the open
position. For alternate sensing device simulate the above.

Sequence of Operation:
1. AC and DC power supplies are normal; enclosure temperature is below
designated set point.
This is considered the “normal”condition, therefore the fan is not required to
operate and the dampers remain in a closed position.
2. AC and DC Power supplies are normal, enclosure air temperature rises above
the set point due to the possibility of air conditioner failure. Alternate sensing
devices can provide this functionality if used.
In this mode, the thermostat contacts open, the fan will operate and the
dampers will open.
3. AC power supply fails; DC power supply is normal.
In this mode, the fan will operate and the dampers will open.
When the primary AC power supply is restored, the fan will stop operation, the
dampers will close and the timer will energize. If after a factory set time period of
1000 seconds or 16.67 minutes (adjustable), the thermostat contact is closed -
indicating a satisfactory enclosure temperature, the fan will remain off and the
dampers will remain closed.
If after the factory set time period the thermostat contact is open, indicating an
enclosure temperature above the thermostat set point, the fan will begin operation
and the dampers will open.
Note: This timed output can be reset by momentarily interrupting power to the DC power
supply circuit. This will increase the time delay another 1000 seconds.
