Maintenance

Periodic Service

￿WARNING

Hazardous Voltage

Open all disconnect switches and secure in that position before servicing unit. Failure to do so may result in personal injury or death from electrical shock.

￿CAUTION

Rotating Components

Allow rotating fans to stop before servicing to avoid serious injury to fingers and hands.

Because of the simple design of the steam and hot water unit heaters, they are nearly maintenance free. However, depending on the environment, simple maintenance practices should be adopted.

Periodically check the finned surfaces and vacuum these as often as necessary to remove any accumulation of lint and dirt. Check fan blades and remove dirt accumulation. If fan blades are not cleaned they tend to become unbalanced.

Most of the motors supplied on the unit heaters have either ball bearings or sleeve bearings and should not require lubrication for long periods of time. It is however advisable that motor maintenance and lubrication recommended by the motor manufacturer be followed.

Check motors for dirt and dust accumulation, and remove any accumulation as often as necessary. Open type motors may overheat if the dirt or dust is not removed from ventilation openings.

Motor Lubrication

Sleeve Bearings

Motors with oilers or oil holes are lubricated before shipment with a good grade of electric motor oil.

Refill when necessary, with the motor at a stand-still, until oil reaches the proper level.

Use SAE 20W non detergent oil for motors operatingin ambient temperatures of 32°F to 100°F (0°C to

38°C). Below 32°F (0°C), SAE 10W non detergent oil will be required.

The frequency of oiling will depend upon operating conditions and length of running time. Inspect the oilers or oil holes when cleaning the unit. If the unit has a fractional horse-power motor, lubricate at least once a year. Under high ambient conditions or constant fan operation, fractional horse-power motors should be lubricated every 90 days. On those motors without oilers or oil holes, follow the instructions given on the motor nameplate.

Ball Bearings

Ball bearing motors are pre- lubricated and normally not equipped with grease fittings. However, motors are equipped with removable grease plugs to allow installation of grease fittings if desired by owner. Motor manufacturers do not recommend or require on the job lubrication of ball bearing motors.

If on the job lubrication is required by the owner, use the following procedure: With the motor at a stand-still, remove the vent and grease plugs. Install grease fitting and add grease sparingly. Remove the old grease from the vent relief chamber. Operate the motor a few minutes before reinstalling the vent plug to allow excess grease to escape. If there is evidence of grease working out around the motor shaft, less grease should be added and the greasing periods lengthened. If grease continues to appear, take the motor to the motor manufacturer’s authorized service station for repair.

Note: Consult local motor manufacturer’s service facility for information on type of grease and oil to be used.

Note: The heater system should be checked once a year by a qualified technician. All maintenance/service information should be recorded accordingly on the

inspection sheet provided in this manual.

Should maintenance be required, perform the following inspection and service routine:

Inspect the area near the unit to be sure that there is no combustible material located within the minimum clearance requirements listed in this manual.

Cleaning the Unit

The unit casing, fan, diffuser and coil should be cleaned thoroughly once a year. Coil heat transfer efficiency depends on cleanliness. The following recommended procedures may be performed when lubricating the motor and cleaning the coil.

1.Wipe all excess lubricant from the motor, fan and casing. Clean the motor thoroughly. A dirty motor will run hot and eventually cause internal damage.

2.Clean the coil:

a.Loosen the dirt with a brush on the fan side of the coil. Operate the motor allowing the fan to blow the loosened dirt through the unit.

b.Use high pressure air or steam on the side of the coil away from the fan.

Note: A piece of cheesecloth or a burlap bag may be used to collect the large particles during the cleaning process.

3.Clean the casing, fan blades, fan guard and diffuser using a damp cloth. Any rust spots on the casing should be cleaned and repainted.

4.Tighten the fan guard, motor frame and fan bolts. Check the fan for clearance in the panel orifice and free rotation.
