Planning The Installation - Honeywell F58G Series Product Data

PLANNING THE
INSTALLATION
Notice:
• Read the maintenance instructions before opening the
appliance.
• Appliances that are obviously damaged must not be
operated.
• Doors and access panels bearing the ULTRAVIOLET
RADIATION hazard symbol which may have UV-C
SPECTRAL IRRADIANCE greater than 1.7 μW/cm
provided with an interlock switch to interrupt the power
to the UV-C LAMPS for your safety. Do not override.
• UV-C BARRIERS bearing the ULTRAVIOLET RADIATION
hazard symbol should not be removed.
• Do not operate UV-C LAMPS outside of the appliance.
WARNING
Only an adult, trained professional should install,
operate or maintain electronic air cleaner or UV
device.
WARNING
The product is dangerous and poses a shock and
fire hazard if it is not installed entirely within a
duct.
Application
The F58G,H is used in a forced air heating, cooling, or
ventilating system. It removes airborne particles from the
air circulated through it. It provides a relay contact that can
be connected to a building management system to provide
remote status indication. It is recommended that only one
unit with WASH indication be installed in each array of
units.
IMPORTANT
Do not mount air cleaner in the discharge air duct.
For most efficient air cleaning, airflow must be spread
evenly across the face of the air cleaner. If the duct is a
different size than the air cleaner array, gradual transitions
are recommended.
Applications With Outdoor Air Intake
Return air temperature must be at least 40°F (4°C). Lower
temperatures can cause ionizer wire failure. If outdoor air is
used, warm it upstream from the air cleaner by:
• Making sure the outdoor intake is far enough upstream
from the air cleaner so the return and outdoor air are
thoroughly mixed.
• Adding baffles upstream from the air cleaner to force
thorough air mixing.
• Installing a preheater if large amounts of outdoor air are
used. (Control the preheater with a thermostat. Protect
the hot water or steam coils with a freeze-up control.)

Choosing Mounting Position
WARNING
Heavy Equipment Hazard.
Can cause injury or equipment damage.
Mount the air cleaner with the power supply on top.
Do not mount the air cleaner with the pre-filter
facing down; the latches may not hold and the cell
and pre-filter can fall unexpectedly.
WARNING
Be careful of damage to equipment.
Ultraviolet light can cause color fading or degraded
structure of plastic material found in HVAC
equipment, avoid plastic material or equipment
with unknown performance against ultraviolet light
in the area of irradiation.
Multiple electronic air cleaner installations are needed for
many commercial systems. F58G,H air cleaners can be
mounted side-to-side, and stacked in rows. Carefully plan
the number of air cleaners and positions before beginning
installation. To visualize the installation plan, temporarily
arrange the desired number of air cleaners on the floor.
Consider the total dimensions, clearance, and accessibility
of all air cleaners before selecting a location.
Constructing F58G,H Array
The F58G,H side flanges are designed so a row of units can
be easily constructed with up to six units per row. Units
should be attached using six no. 8X 1/4-in. (6.35 mm)
sheet metal screws and two #8-32 green ground screws on
each side panel. F58H requires connection to F58G power
supply, maximum one F58H per F58G.
Before attaching the adjacent units, use wire nuts to
connect wires. In addition, multiple rows of units can be
stacked to build an array to the size required for the appli-
cation. Attach upper rows to the rows beneath using four
no. 8 x 1/4-in. (6.35 mm) sheet metal screws per unit in the
holes provided.
Notice:
• The two green ground screws should be placed on each
clinching nut of the panel flange.
Constructing Array Support Structure
WARNING
Construction Collapse Hazard.
Can cause personal injury or equipment damage.
Provide adequate structural support to prevent
array collapse.
Support each unit with external structural elements
across both top and bottom and add cross supports,
as needed.
Provide adequate array support to prevent collapse:
• Provide minimum of external structural support across
the top and bottom of each unit.
• Provide cross supports, as needed.
