Servicing
9.10 Oil filling / Top-up (Fig. 9.3)
Remove and retain the level plug (D) located just behind the
bypass valve (E).
Fill the compressor with oil to overflow. Fluid Force Red 2000 is
recommended as the standard oil.
When the level is correct, oil will overflow from the level plug. Stop
filling and replace the level plug. Clean away any spillage.
Refit the filler plug Fig. 9.2 (A) and bonded seal (B). Renew the
bonded seal if damaged, tighten the plug using a suitable
spanner. Do not over tighten.
9.11 Air Filter Replacement (Fig. 9.2)
To change the air filter element, twist the cap of the air filter
container (D) anti-clockwise then lift vertically to expose the
element.
Remove the old element and discard in a safe manner and
replace with a new element before replacing the cap.
9.12 Oil Separator Replacement (Fig. 9.2)
Unscrew the oil separator (C) in an anti-clockwise direction and
discard in a safe manner.
Using a new separator, smear a small amount of oil onto the seal,
screw clockwise to tighten, hand tight only.
9.13 Clean Oil Cooler/Aftercooler (Fig. 9.4)
Inspect the cooler matrix for signs of damage. If the matrix is
damaged, consult your local Hydrovane Distributor.
The cooler matrix airflow is from the inside to outside; cleaning is
best achieved by brushing and reversing the airflow to dislodge
any accumulation of dirt.
Using low pressure air (2 bar) brush and blow over the whole area
of the matrix (A). Undo two internal cap head screws at the top of
the rear frame to remove the rear panel. Ease the rear panel away
from the frame and lift it clear. Vacuum up debris from the cooler
and surrounding area behind the cabinet filter (B).
All discarded items and waste oil must be disposed of in an
approved manner.
9.14 Cabinet Air Filter
This is a disposable item located in the rear panel that should be
changed every 2000 hours.
Remove the filter by sliding upwards and pull the bottom edge to
clear retaining lips. Refit in the reverse sequence.
9.15 Panel Refitting
Refit the top panel (firm push fit), close the front panel door and
lock with the key provided. Secure all panels including the starter
panel door if opened.
Test run the compressor and check operation using the
Controller.
If the oil filter has been replaced, run for compressor for a short
time (30 seconds) and re-check the oil level.
