Allied K-Series (15-25 KCB): 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 20.
B-Lubrication
All motors used in KGA units are factory lubricated, no further lubrication is required.
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.
D-Condenser Coil
Clean condenser coil annually with detergent or commercial coil cleaner and inspect monthly during the cooling season.
Condenser coils are made of one, two and three formed slabs. Dirt and debris may become trapped between the slabs. To clean between slabs, carefully separate coil slabs and wash them thoroughly. See figure 21. Flush coils with water following cleaning. NOTE - Remove all screws and gaskets prior to cleaning procedure and replace upon completion.
E-Supply Air Blower Wheel
Annually inspect supply air blower wheel for accumulated dirt or dust. Turn off power before attempting to remove access panel or to clean blower wheel.
