INSTALLATION
The system’s weight must be taken into account when choosing the proper installation method
(see specication). Follow all applicable building and electrical codes.
The RH60 Series Hood Assembly comes with (4) eyelets for rod hanging the system or can be
oor mounted with optional column support assembly. When using the eyelets for hanging, it is
critical that you do not angle the support rods, they must be installed straight above the eyelet to
maintain the integrity of the eyebolt. See Figure 2 below. For complete Assembly drawing and
parts list, refer to appendix.
Mounting materials must be able to support the weight of the air cleaner plus the additional
weight of the material collected. Consult your local building code for proper installation methods
and materials. Failure to use the proper materials could result in injury or damage equipment
and will void the warranty.
HEIGHT REQUIREMENTS
To insure worker and building safety, Industrial Maid recommends that RH series hoods be
mounted a MINIMUM of 5 ft or greater above the highest point of arc in welding applications.
The hoods are designed with a low intake velocity and spark bafe to avoid capturing sparks and
ammable debris generated during the welding process. Failure to maintain a safe distance
from the welding arc can result in unsafe operating conditions, injury or property damage.
Consult with your distributor , Insurance underwriter and local re authority to insure a safe
installation.

ELECTRICAL WIRING
Unit comes wired to a junction box Additional wiring will be required to get power to unit, which is not
supplied with this product.
Motor Starters, disconnects, wiring, overloads, and thermal protection are NOT provided by the
Manufacturer
All Field wiring should be performed by a qualied electrician and must meet all local and NEC codes.
Failure to install the proper electrical wiring, thermal protection, and controls will void the warranty.
ROTATION - On single phase units motor rotation can be reversed by switching the black and red leads
in the motor, always refer to motor nameplate when switch leads for rotation. Three phase motors can be
reversed by switching leads L1 and L2. VERIFY rotation before operating the air cleaner to avoid over
amping the motor, voiding warranty.
After completion of the eld wiring, turn the unit on to check for proper rotation. Rotation is marked on the
side of the blower housing for the standard forward curve blower. Optional direct drive BI blower wheels
will rotate in a clockwise direction when looking at the top of the motor, or the wheel should be spinning
from right to left as viewed through the exhaust grid. Backward rotation will result in a much lower air
ow, louder noise, and will over amp the motor. Check the motor nameplate before switching wires and
reversing rotation, to ensure the unit is operating at or below rated full load amp draw. Figure 6 illustrates
how to identify the proper rotation.

FILTER MAINTENANCE
METAL PRE-FILTERS - Standard RH Series hoods area supplied with a 2” spark bafe inlet. Part
BF02-2424. Inlet bafes shall be kept free of oil, ammable debris and particulate at all times.
Bafes should be removed and washed as soon as noticeable build up of particulate (discoloring)
occurs. Visually inspect the metal pre-lters weekly to determine if they should be cleaned. To
remove the bafes, simply slide out of the pre-lter tracks located on the underneath side of the hood.
Bafe are galvanized steel and can be rinsed with warm water or mild detergent. Allow to dry and
replace.
Some applications may require the optional aluminum mesh pre-lter, FA02-2424. Due to the nature
of the tight woven pattern of the aluminum mesh, particulate build up may be accelerated, thus
requiring more frequent cleaning. Aluminum Mesh lters shall be kept free of oil, ammable debris
and particulate at all times. Industrial Maid recommends washing aluminum mesh lters as soon as
noticeable buildup of particulate or discoloring occurs. Visually inspect the metal pre-lters weekly to
determine if they should be cleaned. Aluminum mesh lters are to be removed and rinsed with warm
water or mild detergent. Allow to dry and replace.
The Metal Pre-lters supplied by the factory are not a re hazard. Failure to properly maintain
all lters can allow for the buildup of ammable materials in some applications. Proper lter
maintenance must be maintained for the safe operation of the RH series hood.
PLEATED PREFILTERS - The RH Series hoods are supplied with a standard 4” pleated pre-
lter (FP44-2424), rated Class 2 under UL standard 900 & operating temperature of 180 degrees
Fahrenheit. Filter life for replaceable media varies greatly per application. Industrial Maid
recommends a monthly service interval consisting of a visual inspection of the pleated pre-lters,
replacing as needed.
MAIN BAG FILTERS - The RH Series hoods are supplied with a standard 95% efcient extended
surface berglass bag lter, rated Class 2 under UL standard 900 & operating temperature of 180
degrees Fahrenheit. Filter life for the Main Bag Filter varies greatly per application. Bag lters
should be serviced when the pressure drop across the bag lters reach 1” w.g.
Pressure drop is best measured by installing a lter service gauge (manometer or magnahelic
pressure gauge), available from Industrial Maid. With clean lters and the gauge properly installed,
make note of the reading on the pressure gauge. Add 1” to that number, this is will give you the point
at which the lters need serviced. Replace accordingly.
Failure to properly maintain all lters can allow for the buildup of ammable materials in some
applications. Proper lter maintenance is required for the safe operation of the RH series hood.
SAFETY AFTER FILTERS - The RH series is available with an optional HEPA after lter system.
HEPA lters are rated at 99.97% efcient, 180 degree Fahrenheit & Class 2 under UL std. 900. For
safety purposes, HEPA lters should be replaced every 12 months or when the pressure drop across
the media increases by 1.0” w.g. , whichever comes rst.

MOTOR MOUNTING
Motor must be securely fastened to a rigid, at surface to prevent vibration and minimize noise.
For secure mounting use high-quality bolts of the largest possible diameter.
Belt-drive sheaves must be in-line. Use a straight edge to check. Do not over-tighten belts.
Direct coupled installations require a careful check of shaft and coupling alignment, shaft offset
and/or angular misalignment should be less than .002”. Shim motor base as necessary. Do not
depend on a exible coupling to compensate for misalignment.

RECOMMENDED MAINTENANCE
WARNING
All aspects of the installation must conform to the requirements of
the NEC, including Article 430 (Motor circuits and Controllers), and all
local codes.
Wherever possible, each motor should be powered from a separate circuit of adequate capacity
to keep voltage drop to a minimum during starting and running. Increase wire size where motor is
located a distance from the power source. Wire size must be adequate to minimize voltage drop
during starting and running. Refer to Tables A and B for suggested wire sizes. Distances shown
are one-way between source and motor. Portable cords, if used, should be as short as possible
to minimize voltage drop. Long or inadequately sized cords, especially on hard starting loads, can
cause motor failure. All electrical connections in system must be secure to prevent voltage drop
and localized heating.
• Determine direction of rotation before connecting driven equipment to prevent damage.
• To prevent bearing damage, do not strike shafts with hammer or other tool.
• If the motor has been damp or wet, then have motor serviced by a qualied motor repair
shop before operating.
Recommended Maintenance
Remove dirt accumulations in and around vent openings, by vacuuming. Dirt accumulations
can cause motor overheating and a re hazard. Enclosed motors can be cleaned with an air
jet; wear eye protection.
Periodically inspect the installation. Check for dirt accumulations; unusual noises or vibration;
overheating; worn or loose couplings, sheaves and belts; high motor current; poor wiring or
overheated connections; loose mounting bolts or guards; and worn motor starter contacts.
Dayton ball-bearing motors without lubrication provision do not require periodic relubrication.
Where motor has provision for bearing lubrication, lubricate as follows:
1. After stopping motor and disconnection power, thoroughly wipe the housing around both of
the motor bearings, ller and drain plugs (on TEFC) ratings, remove fan cover for access
to plugs).
2. Remove ller and drain plugs and install a 1/8” pipe thread lube tting in ller hole.
3. Using a low pressure grease gun, pump new grease into motor until it appears at the drain
hole.
4. Run motor for several minutes to discharge excess grease. Shut motor OFF, replace ller
and drain plugs, and reinstall fan cover.
See Table C for suggested regreasing intervals.
