Allied K-Series ( 15 - 20 KHA): Annual Maintenance

The annual maintenance procedure focuses on B-lubrication, filters and condenser oil. The main purpose of regular maintenance is to ensure that all equipment required for production is operating at 100% efficiency at all times.

    VI-MAINTENANCE

    The unit should be inspected once a year by a qualified service technician.

    A-Filters

    Units are equipped with six 24 X 24 X 2” filters. Filters should be checked and replaced when necessary with filters of like kind and size. Take note of air flow direction marking on filter frame when reinstalling filters. See figure 14.

    B-Lubrication

    Blower shaft bearings are prelubricated. For extended bearing life, relubricate at least once every two years with a lithium base grease such as Alvania 3 (Shell Oil), Chevron BRB2 (Standard OIl) or Regal AFB2 (Texas Oil). Use a hand grease gun for lubrication. Add only enough grease to purge through the bearings so that a bead of grease appears at the seal lip contacts.
