Spencer FastVac Vacuum Cleaning Systems - Manual (Page 5)

V. Operation and
Adjustments
Each FastVac unit is designed to operate as part of a vacuum
system that includes a Spencer tubing and fittings network
(stationary models) and Spencer hose and tools (all models).
These genuine Spencer components are engineered specifically
for heavy-duty vacuum cleaning systems; other components
may not provide the performance desired.
Machine Startup
1. Turn the FastVac system on, having completed the previous
setup procedures.
2. Without any vacuum hoses connected, observe that the
vacuum relief valve opens and operates correctly.
NOTE: When no hoses are connected, the mobile FastVac unit
and the stationary unit with its attached tubing network are
closed systems with no entering air-flow. They must rely on the
vacuum relief valve to create a bypass airflow to protect the
vacuum producer.
Stationary Model. If the vacuum relief valve is closed and
exhaust air can be felt at the Vortex discharge, air is entering
the tubing network somewhere. Find the leak and correct it.
3. All Models.With the machine running, connect the Spencer
hose(s) and tools. Verify that the vacuum relief valve is now
closed.
4. Use the tools to pick up at least a quart of suitable dry dirt or
debris.
5. Shut the machine off. Wait for the Vortex vacuum producer
to stop. Pull the dirt can bail up and verify that dirt has
accumulated in the can.
6. Remove the dirt can and verify that dust has fallen off the
filter cartridge into the can. Empty the can.
7. Reposition the can and push the dirt can bail down to lift the
can against its gasket. Your system is ready to use.
Limits of Operation
Maximum permissible vacuum is listed on the FastVac name-
plate; when it occurs during operation, the minimum allowable
airflow (CFM) also occurs. Maintain the operating vacuum at
less than maximum to avoid low flow operation and overheating
of the vacuum producer. (See vacuum relief valve settings on
page 4.)
Caution: Overheating the vacuum producer at low-flow
conditions may create a burn hazard. Do not touch the
operating machine.
VI. Maintenance
Vortex Vacuum Producer
For maintenance information about the Vortex vacuum source
consult Spencer or obtain a copy of the Vortex manual, Form ZZ.
Vacuum Relief Valve
No maintenance is required.
Separator
Empty the dirt can daily when the FastVac system is new. It will
likely collect large amounts of material at first. After a while, the
daily collection will stabilize at a normal load for your particular
facility. At that time, establish the appropriate interval for dirt can
emptying.
Cartridge
Clean the filter cartridge daily or more often if suction drops
from excessive cake build-up. To reach the cartridge, remove
the top cover and place it on the floor with the bottom of the
filter resting on the floor. Loosen and remove the four nylon
nuts holding the cartridge to the top cover. Lift the top cover off
the filter cartridge.
Use a soft paint brush or compressed air to carefully remove
any dirt cake on the outside of the cartridge. Or, since a spare
cartridge is provided, you can remove the dirty one, install the
spare and use the vacuum system and tools to clean the dirty
cartridge.
Replace the cartridge when if it can no longer be cleaned, if it
gets damaged by materials collected or is torn. Spare cartridges
may be purchased from Spencer.
To install a new cartridge, place the bottom of the filter on the
floor with the four studs facing up. Lower the top cover over the
studs. Install a steel washer and nylon nut on each stud and
tighten.
NOTE: If a ground wire is connected to the filter cartridge, it
must be reconnected to a ground lug on the cartridge plate
assembly.
NOTE: All gaskets must be in place and properly aligned when
the cartridge is reinstalled.
CAUTION: Dust coming out of the vacuum producer outlet
may indicate a damaged cartridge. Shut off the system
immediately and inspect the cartridge as well as the seal-
ing system which holds the cartridge in place.
Housing
The exterior of the machine is painted with a urethane semi-
gloss finish over an epoxy primer. Periodically wipe down the
machine with a dry cloth or use a non-abrasive water-based
cleaner to remove stubborn dirt. Do not spray water onto the
machine or electrical connections. An automotive wax may be
applied to the machine exterior to help protect the finish.
