ELECTRIC MODELS:

1)If motor fails:

•If motor is extremely cold.

o Bring to room temperature before starting.

•Ensure respirator and hose are connected when pump is running; failure to do so may cause lock-up. o Loosen all six pump endplate bolts slightly. Re-tighten and try to run unit.

•Some motors are thermally protected. An electrical overload or mechanical failure may cause a thermally protected motor to stop running.

o Let motor cool down (15-20 min.) and try restarting.

•If the motor fails to start or hums.

o Pull plug and check for correct electrical current as shown on motor nameplate. o Check the wiring instructions on motor case or on thermal plate cover.

•If electrical motor hums but the air pump is not turning.

o Turn off motor, loosen all six end plate bolts, then re-tighten and start unit. o If unsuccessful, remove endplate.

o Check vanes and rotor for free movement. o Broken or chipped vanes should be replaced.

•If rust has formed in pump chamber due to exposure to moisture. o Sand down if necessary.

o Clean chamber with approved solvents.

•If pump becomes noisy.

o Check for sticking vanes.

o Flush pump, if necessary replace vanes (see disassembly for instructions)

2)If output air hot or pump is running hot:

•If there is a drastic temperature increase on pump surface or air temperature coming out of the respirator. o Check alignment of pump rotor and housing. (see Maintenance section)

•If outlet pressure is too high.

o Adjust pressure relief valve, while maintaining sufficient air flow to the respirator.

•Check inlet and/or exhaust filter for excessive dirt or dust. o Replace if necessary.

•Check airline hose.

o Loosen hose coils to allow heat to dissipate. o Use NIOSH approved airline hose only.

o Do not use more than 100 feet of airline hose per respirator user.

o Joining separate lengths of airline hose to complete 100 feet will increase pressure and temperatures.

3)If there is a rise in outlet pressure:

•Check for kinked airline hoses.

•Make sure only NIOSH approved airline hoses are used

•Adjust pressure relief valve, to adjust for any change in number of users, or lengths of airline hose. o Check condition of filter elements.

o Replace if necessary.
