INSTRUCTIONS FOR INSTALLING MOTOR-MOUNTED BLOWER KIT(With or Without Filter)A blower kit consists of the following items:1. A blower assembly complete with a-c motor.2. Two solid hand-hole covers.A filter kit is supplied as a separate item if specified.The kit is suitable for modifying a drip-proof selfventilatedd-c motor of suitable rating and frame size toconvert it into forced-ventilated motor mounted blowerconstruction. The blower will provide to the motor aconstant supply of ventilating air with the cubic feetper minute and static pressure required for the rating.The blower is normally mounted on the top hand-holeopening of the commutator end bracket with the air inletpointed away from the drive shaft end of the motor. Theblower can also be mounted on the side of thecommutator end bracket opposite the conduit box side.The d-c motor internal fan may be left in position providedthe blower is installed on the commutator end bracket.The d-c motor must not be energized or operatedwithout the blower running.IMPORTANT — To insure adequate protection of ablower ventilated motor against loss of cooling air, amotor thermostat or air flow switch for interlocking withthe controller overload protection circuit isrecommended.FIGURE 1 — Blower without filter assembled on d-cmotor.To mount the blower:1. Remove all of the hand-hole covers from thecommutator end bracket. (Bracket opposite thedrive end.)2. Retain the solid cover and mounting cap screwsfor future use. Discard the louvered covers andscreen cover if provided.3. Mount the blower assembly on the selected handholeopening using the cap screws provided withthe kit. Refer to Figure 1.4. Mount the two solid hand-hole covers provided withthe kit and the one solid hand-hole coverremoved from the bracket on the three remaininghand-hole openings using the cap screws previouslyprovided for the hand-hole covers.5. Connect the a-c blower motor through a starter (notincluded in the blower kit) with a suitable source of a-cpower so that the blower motor will turn the blower'swheel in the proper direction. The standardblower motor is for three phase, 50/60 Hz,230/460 volt power.) Blower motors for singlephasedrive motors may be rated for single-phase,50/60 Hz, 230 volt power.) Blower motors for othera-c supplies are available on special order. Checkthe nameplate on the blower motor to make sure itmatches the available a-c source and control. Checkthe blower motor full load current on the motornameplate to make sure it matches the rating ofthe overload relay setting or heater in the blowerstarter.6. Before starting the blower motor, make sure theblower wheel mounted on the shaft of the blowermotor turns freely without any interference or binding.7. Start the blower motor and check for the properdirection of rotation. Check to make sure that theblower assembly and the solid covers on the frontend bracket are tight and properly gasketed toprevent leakage of ventilating air. Listen to theblower and blower motor for any noise that wouldindicate abnormal operation.IMPORTANT — Actually check blower rotation. Donot depend on the "feel" of the amount of exitair. Motors may appear to have sufficient aircoming out of the exit louvers when the blower isrotating in the wrong direction.8. Mount Filter Kit, if included, as follows:IMPORTANT — Follow instructions for yourspecific kit part number.Frames B320ATZ thru B400ATZFilter kits will fit blower kit as follows:Filter Kit Blower Kit DC Motor Frame Size417077-5417077-6417077-7417077-2417077-3417077-4B320ATZB360ATZB400ATZa.

Push inlet flange and filter against blowerhousing and secure with the three wing nuts onthe filter studs.WARNING: FILTER MUST BE IN PLACE WHENOPERATING THE MOTOR TO GUARD AGAINSTPOSSIBLE CONTACT WITH THE BLOWER WHEEL.SUMMARY CHECK LIST1. Confirm that the blower kit is matched to the d-cmotor frame and rating.2. Confirm that the blower motor rating matches thepower supply.3. Confirm that the blower motor overload ratingmatches the motor full load current.4. Confirm that motor thermostat or air flow switch isinterlocked with controller overload protection circuit.FIGURE 2 — (Top) Assembly of round filter onframes DB180ATZ — B360ATZ; (Bottom) Blower withround filter mounted on d-c motor.5. Confirm that the blower motor is connected for theproper direction of rotation.6. Confirm that the blower motor and wheel turn freelyby hand before starting.7. Confirm that the blower motor and wheel rotatesin the proper direction when running.8. Confirm that there is not unwanted leakage of air.9. Confirm that the blower and motor operates with thenormal sound of forced air.IMPORTANT — Filters will become clogged with dirt innormal operation and must be cleaned or replaced toinsure that the proper volume of ventilating air isprovided to the motor.CAUTION — SURFACE TEMPERATURE OFMOTOR ENCLOSURE MAY REACH TEMPERATURESWHICH CAN CAUSE DISCOMFORT OR INJURY TOPERSONNEL ACCIDENTALLY COMING INTOCONTACT WITH HOT SURFACES.
