Permit-Required

Conned Spaces

A conned space has limited openings for

entry or exit, is large enough for entering and

working, and is not designed for continuous

worker occupancy. Conned spaces include

underground reservoirs, ground storage tanks,

elevated tanks, silos, manholes, and pipelines.

Conned Space Tips

• Do not enter permit-required conned spaces

without being trained and without having a

permit to enter.

• Review, understand and follow employer’s

procedures before entering permit-required

conned spaces and know how and when

to exit.

• Before entry, identify any physical hazards.

• Before and during entry, test and monitor for

oxygen content, ammability, toxicity or

explosive hazards as necessary.

• Use fall protection, rescue, air monitoring,

ventilation, lighting and communication

equipment according to entry procedures.

• Maintain contact at all times with a trained

attendant either visually, via phone, or by

two-way radio. This monitoring system

enables the attendant and entry supervisor

to order you to evacuate and to alert

appropriately trained rescue personnel to

rescue entrants when needed.

Refer to 29 CFR 1910.146 for complete

regulations set by OSHA. Refer to your state's

regulations if your state established and operates

their own safety and health programs approved

by OSHA.

Protect Yourself

It is important that you comply with all relative

OSHA and local regulations while installing

and performing any maintenance to the mixer

circulation equipment.

Key OSHA Compliance Standards that must

be followed (and not limited to) are:

• 1910.146 Permit-required conned spaces

• 1910.147 Lockout/Tagout

• 1926.500 Fall Protection

Fall Protection Tips

• Identify all potential tripping and fall hazards

before work starts.

• Look for fall hazards such as unprotected

oor openings/edges, shafts, open hatches,

stairwells, and roof openings/edges.

• Inspect fall protection and rescue equipment

for defects before use.

• Select, wear, and use fall protection and

rescue equipment appropriate for the task.

• Secure and stabilize all ladders before

climbing.

• Never stand on the top rung/step of a ladder.

• Use handrails when you go up or down stairs.

• Practice good housekeeping. Keep cords,

welding leads and air hoses out of walkways

or adjacent work areas.

Refer to 29 CFR 1926.500 for complete

regulations set by OSHA. Refer to your state's

regulations if your state established and operates

their own safety and health programs approved by

OSHA.

Lockout Tagout

When the On/Off switch is in the "ON" position,

the mixer may start up at any time if not already

operating. The mixer's On/Off switch can be

locked out by placing a pad lock thru the door latch

of the controller after the switch has been turned

to the "OFF" position. The On/Off switch is to be

used as the emergency stop.

Placement Checks

Before starting the Blower Unit a few checks need to be done to conrm the placement is correct.

Placement Check Check

Is the blower properly secured to the isolation pads?

Is the motor wired properly to match the source voltage? Follow the motor wiring diagram on the motor

decals.

Does the blower have a local disconnect capable of being locked and tagged out for proper safety

precautions for blower maintenance and electrical adjustments? (i.e. checking bearings)

Is the control panel wired correctly? (Control Panel Diagram)

Is the blower ducting properly supported and airtight at all joints and connections?

Is the Motor rotating the correct direction? (See Rotation Check below)

Final Checks

Now that the install checks have been completed. Now to conrm the continuity and discontinuity and then

start the Blower Unit.

Rotation Check

Before nalizing the placement, the motor

rotation needs to be checked. With someone

observing the Blower Unit, briey turn the unit

on for several seconds and observe the motor

rotation, observing the motor cooling fan or

blower fan wheel. As the blower slows down,

observe that the drive assembly is rotating

the same direction as indicated on the blower

motor. If the motor direction needs to be

reversed; for three-phase motors, switch L1

and L2 at the motor or blower disconnect; for

single-phase motors, follow the instructions on

the motor wiring decal.

Caution: Never attempt maintenance on a blower unless the electrical supply has been completely

disconnected, and lockout/tagout procedures are followed. The rotating assembly may also need to be

secured to eliminate the potential for wheel rotation due to other means such as wind milling or back

feeding from other blowers.

General Maintenance:

Blowers must be regularly inspected, the frequency being determined by the severity of the application. Routine

inspections should include the following checklist:

1. Check for wear, corrosion, and material build up on the blower wheel and/or housing and clean or replace as required.

2. Check the drive for proper alignment and lubrication.

3. Lubricate the bearings of the blower and motor. Never over lubricate.

4. Check for worn shaft seals and repair or replace as necessary.

5. Check all setscrews and bolts for tightness. Check isolation bases for freedom of movement, looking for broken or

deteriorated rubber elements.

Bearing Maintenance:

DODGE IP and ISAF bearings are pre-packed with NLGI #2 Lithium Complex grease. For re-lubrication select a grease

that is compatible with a #2 Lithium Complex grease.

High Speed Operation - in the higher speed ranges, too much grease will cause over-heating. The amount of grease that

the bearing will take for a particular high speed application can only be determined by experience. If excess grease in the

bearing causes overheating, it will be necessary to remove grease tting to permit excess grease to escape. The bearing

has been greased at the factory and is ready to run. When establishing a relubrication schedule, note that a small amount

of grease at frequent intervals is preferable to a large amount at infrequent intervals.

Ixom strongly cautions against over-greasing with too large of amounts per application as stated above. Only

personnel that understand using a very little amount of grease per application should be responsible for

lubrication of the bearings on the equipment we supply.

Air Filters:

The use of any type of lter requires that it be kept clean to prevent excessive pressure drop in the lines.

The dry element of the lter may be cleaned with soap & water and reused.

A total of six pleated lters occupy the lter housing. It is recommended the lters be cleaned periodically,

and especially leading into seasons of critical application.

Filter elements should be replaced when showing signs of wear which may be typical after several washes.

Filter element replacements should comply with the below requirements.

owner postage-paid and may pay the owner a reasonable labor allowance, as determined solely by

Ixom, to install the parts. There is no liability for consequential damages of any type. The warranty

that is submitted and provided with the purchased equipment is the valid warranty.

GridBee control panels, and any optional accessories. These items are considered “buyout”

items for Ixom, and as such include a warranty against defects in material and workmanship for one
