Figure 76: Oil Filter Housing Cover Plate
Oil lter assembly components are:
• Oil Filter – 250mm
• Oil Filter Housing Cover
• O-Ring – 89.5x3
• O-Ring – 76.1x3.4
• (6) M8 Bolts
Disassembly Procedure
1. Unscrew and remove two hex head side cover bolts 180°
apart. Insert M8 guide studs into the vacant holes.
2. Remove remaining bolts and oil lter housing cover.
3. Pull the oil lter off of the spigot and withdraw the oil lter
from the housing and clean the housing.
4. Clean oil lter housing cover plate and all other
components.
Fitting a New Oil Filter Element – Reassembly
Before reassembly, remove any paint from joint faces. Inspect
parts individually for damage and ensure they are completely
clean before laying them out on a clean surface in a logical
order ready for reassembly.
Use fresh refrigerant oil to lubricate parts during reassembly.
1. Install new O-rings on the oil lter housing cover.
2. Insert new oil lter into the housing, ensuring the lter
sits tightly on the sealing spigot.
3. Replace the oil lter housing cover.
4. Evacuate air and non-condensibles before valving
refrigerant back into the compressor.
Electrical Terminals
DANGER
Electric equipment can cause electric shock which will cause
severe personal injury or death. Turn off, lock out and tag all
power before continuing with following service. Panels can
have more than one power source.
CAUTION
Periodically check electrical terminals for tightness and tighten
as required. Always use a backup wrench when tightening
electrical terminals.
All-Aluminum Condenser Coils
The condenser coils are an all-aluminum design including the
connections, microchannels, ns (an oven brazing process
brazes the ns to the microchannel at tube), and headers
(see “Microchannel Coil Cross Section”), which eliminates
the possibility of corrosion normally found between dissimilar
metals of standard coils.
During the condensing process, refrigerant in the coil passes
through the microchannel at tubes, resulting in higher
efciency heat transfer from the refrigerant to the airstream. In
the unlikely occurence of a coil leak, contact Daikin Applied to
receive a replacement coil module.
