(90 /f) to avoid undue structural fatigue and damage.
Each unit is factory tested for airflows and filter leaks prior to shipping. On occasion damage
can occur during the transportation of your new Total Exhaust Hood. Carefully remove the
crating from your hood and inspect for damage that may have been caused and report it
immediately to your transportation company.
All shipments are F.O.B. Design Filtration Inc. You must file a claim directly with the freight

Installation
Once in location it is recommended that your hood be re-tested for airflows and leaks by an
independent testing organization with technicians trained in the evaluation and maintenance
of HEPA filtered equipment. Always use safe lifting guidelines when installing your hood on
a base frame or existing work bench.
Do not use a lift truck when moving your Total Exhaust Hood. Leave your hood on the
shipping skid until it is in its final installation location. Never lift from the centre of the hood.
Allow hood to acclimatize to room temperature, before installation.
WARNING:
Allow 24 Hrs for Hood to
Acclimatize Before Installation,
to Prevent Damage to Hood.
WARNING:
Always Lift from the
Outside Edges of Hood
to Prevent Damage.
Do Not Use Fork Lift
on Center of Hood.
Your Total Exhaust Hood is shipped to
you in four pieces. To start, locate the
base frame as close to the final area as
possible, allowing enough space for the
head section and personnel to move
freely around the front or back.
Place the wood blocks supplied, angled
across the corners of the work surface, as
shown in Figure 2.1. Raise the head
section keeping as straight as possible.
Move head section over base, and gently
lower on the wood pieces, avoiding
damage to fingers. Lifting one end at a
time remove wood spacers and lower to
base section, aligning connection screws
as shown.
Figure 2.1

Lift rear plenum and align with pre-drilled holes, see Figure 2.2. Insert all of the screws
before tightening them. Connect plastic tubing to fitting on transition. Supply fans will not
run unless tubing is connected.
Figure 2.2
3.
Pre-filter
Your Total Exhaust Hood is equipped with disposable pre-filters, which are manufactured
from a bonded synthetic media set into a moisture resistant beverage board. Pleated prefilters carry an efficiency rating of MERV 7 (Minimum Efficiency Reporting Value). The filters
also provide an Average Atmospheric Dust Spot Efficiency of 25-30% to ASHRAE Test
Standard 52.1
4.
Pre-filter Maintenance
Please check your pre-filters on a monthly basis and change as necessary. To change your
pre-filter simply remove old pre-filters and replace with new pre-filters. No tools are required

5.
HEPA Filter
Your Total Exhaust Hood features a 5.88” deep wood frame filter with a separatorless type
media to provide excellent even airflows. The wet laid glass media is set into the frame with
a urethane seal. Efficiency is 99.99% at 0.3-micron particle size and larger. HEPA filters
cannot be cleaned and must be replaced when necessary, consult factory for replacement
filters.
6.
ULPA Filter
The optional ULPA filter is rated 99.9995% at 0.12-micron particle size and larger. Other
features as per HEPA filter. ULPA filters cannot be cleaned and must be replaced when
necessary.
7.
Changing HEPA / ULPA Filters
Before beginning to change your HEPA Filter,
disconnect your hood from power source.
Carefully remove front access panel to reveal
interior compartment.
Loosen threaded rods at front and rear of fan
filter module. Unscrew and remove
polypropylene front locating bar. Remove
¼–20 nuts from rear clamping mechanism.
Unplug fan power cords from electrical outlet.
Carefully slide fan filter module from housing
(this may require two people.) Remove
aluminum foil tape and separate the filter from
motor housing. See Figure 7.1.
Figure 7.1
Carefully remove the new HEPA filter from crate. Using aluminum foil tape (do not use duct
tape) complete at least 3 layers of tape joining the fan housing to the filter. Apply a thin
layer of vacuum grease to gasket before re-installing the filter. Carefully lift and place filter
back into the hood making sure the HEPA filter is not damaged. W hen tightening threaded
rods, do not over tighten as these are only used to hold filter housing in place.
Once entire unit is re-assembled it must be tested and certified by a qualified certification
company.
8.
Changing the Fluorescent Light
Carefully remove the screws on the lense cover, remove the bulb and install new bulb with
same type and color as original supplied.

Speed Control
The speed control should only be adjusted by a qualified service technician. Adjusting the
airflow will affect the operation of your hood due to the critical balance required. Remove
front snap cap located on the front panel to access the speed control. Use a flat headed
screwdriver to adjust speed, turning clockwise to increase speed. After adjustment of the
speed control, airflows should be checked to ensure it is within the specified range as
outlined in chart. Refer to IES standard IES-RP-CC-002.2.
10. Exhaust System Safety Pressure Switch
This switch is located inside the head section and is connected to the exhaust collar via
tubing. In the case of total or partial exhaust failure, this switch will turn off the supply fans,
ensuring no air will be blown out of the containment work zone. Supply fans will not run
unless tubing is connected.
11. Model Number
The model number is located on the front panel in the lower right hand corner. The serial
number and electrical information is also included on this label. Refer to these numbers
when contacting the manufacturer.
12. Motor / Electrical
The Total Exhaust Hood uses 115-volt, 90-watt energy efficient motorized impellers to
provide excellent airflow distribution, quieter noise levels and low heat loads. Standard on
your Total Exhaust Hood is a FT2 type CSA approved 3-prong electrical cord. Always
unplug your hood when servicing.
13. Changing Sash Window Cables
Should the event of a sash cable replacement be required lift the window as high as
possible and support with two wooden studs cut to length. Remove the interior side panels
(LHS and RHS), remove the old cable and support the weight with a temporary 2” high
stand (this will compensate for stretching of the cable later). Attach new c’’ dia.
polypropylene rope, with a rating of at least 45lbs, to window end first. Thread through
pulleys and secure around weight eyelet with cable as tight as possible.
Always change both ropes at the same time. Consult factory for full rope specifications.

15. Airflow Direction
W hen the Total Exhaust Hood is
operating, the fans draw lab air into the
hood from the top through the pre-filter
and the HEPA/ULPA filter, and then
pushes the cleaned air down to the work
surface. Figure15.1 shows the direction
of airflow in the hood.
