SECTION VI
ROUTINE MAINTENANCE
Very little maintenance is required on the VSE. The following outlines the routine maintenance required.
Loss of Vacuum
If system vacuum is lost as indicated on the vacuum gauge, check the following:
-
Check hose for damage or internal blockage
-
Check for adequate air supply
-
Check the canister for dents along the rim which may prevent a positive seal
-
Check to insure the intermediate or pre-filter is clean and free from dirt and dust
Replacement of Loaded Paper Filter Bags
-
Remove the power head assembly, H.E.P.A. filter, and white intermediate filter
-
Push cardboard tab on filter bag off the air inlet tube
-
When the paper filter bag is full, remove by turning canister on its side to facilitate removal. Remove paper backing
from sealing flap located over cardboard collar. Press sealing flap firmly over the opening to prevent leakage of
recovered material.
-
Dispose of the filled filter bag into the plastic container bag. Tie off bag to insure no spillage occurs. The plastic
bags have storage capacity of 5 filter bags.
Replacement of the Pre-Filter (White)
-
Under normal conditions the pre-filter is changed after every fifth paper filter bag is replaced or whenever there is
damage to the pre-filter or a visible collection of debris on the outside of the filter.
-
Prior to removing the pre-filter, wipe down all exposed surfaces on the underside of the removed lid (tower head)
using a dampened cloth.
-
Remove the pre-filter from the H.E.P.A. filter and be careful not to damage or puncture the paper media used in
this unit.
DO NOT ATTEMPT TO CLEAN THE PRE- FILTER IN ANY WAY. DISPOSE OF IN THE SAME
MANNER AS DESCRIBED IN THE PRECEDING SECTION.
-
Prior to any further cleaning of the canister, place a new pre-filter onto the H.E.P.A. filter. Replace the filters into
the canister, then replace the air Venturi head and clamp in place by engaging the clamp assemblies.
CLEANING AND INSPECTION
Always wear an OSHA approved face mask for use with asbestos and other hazardous materials every time you are using
this vacuum recovery system. You should also wear suitable gloves and protective clothing.
-
Disconnect the vacuum unit from the compressed air supply.
-
Carefully and slowly remove only the lid and set the lid and filter aside.
-
Using a damp cloth, wipe down all of the exposed surfaces inside of the canister. Put the cloth aside.
DO NOT
DISCARD CLOTH.
-
Carefully and
very
slowly, push the paper filter bag down and off the intake tube, using the attached cardboard
collar. Remove the paper backing from the sealing flap located over the cardboard collar. (Note: If the filter bag
does not have sealing flap use adhesive tape). Press the sealing flap firmly over the opening to prevent spill-back
of the recovered material. After the collar is removed from the intake tube, take the damp cloth and wipe off any
surfaces that were not previously wiped. At this time, re-wipe the entire inside of the canister and drop the wiping
cloth into the OSHA approved poly bag.
CAUTION:
HAZARDOUS MATERIALS MUST BE DISPOSED OF PROPERLY. NEVER THROW CONTAMINATED
DEBRIS IN WITH YOU USUAL TRASH RECEPTACLE. PLACE DEBRIS IN A 6 MIL POLY BAG OR A CAN MARKED
WITH A “HAZARDOUS MATERIALS” WARNING AND DISPOSE IN ACCORDANCE WITH YOUR LOCAL
HAZARDOUS WASTE REGULATIONS.
