General Maintenance - Prochem Steempro SX2000 POWERFLO Safety, Operation & Maintenance Instructions

All Prochem machines are engineered and built to
require a minimum of maintenance. But like any
machine, it does require some care to keep it in
optimum working condition. Careful attention to
these maintenance instructions will give you
maximum operating performance and will increase
the life expectancy of the machine.
To ensure a trouble-free machine, we strongly
advise the following preventative maintenance.
DAILY MAINTENANCE
The following should be carried out at the end of
each carpet cleaning session.
POWER CABLE & PLUG
Check the condition of the power cable and plug.
Make sure all wires are correctly located and tightly
connected. If damaged, the power cable and plug
assembly must be replaced.
DO NOT ATTEMPT REPAIR.
Instruction for replacement of power cable with
combined plug (all machines)
!! CAUTION - ONLY QUALIFIED MAINTENANCE
PERSONNEL SHOULD ATTEMPT THE
FOLLOWING REPAIR
Should the power cable require replacement,
please follow the instructions below.
1. The replacement cable and plug shall be of the
same specification as the original Prochem part
number BE4901 (3 core 1.5mm with 13Amp
sealed plug unit)
2. Ensure that machine is disconnected from
electrical supply and open electrical housing by
means of tool required.
3. Disconnect the live (brown), neutral (blue) and
earth (green/yellow) wires from the cable
terminal block by means of unscrewing the
terminal block wire clamp screws.
4. Release the outer cable clamp next to the
terminal block by unscrewing the two securing
screws, then unscrew the outer cable gland to
release the cable which can then be pulled out
of the cable gland assembly.
5. Insert the new cable through the gland, then
secure and clamp the outer cable by means of
tightening the outer cable gland and the two
securing screws next to the terminal block.
6. Connect the live (brown), neutral (blue) and
earth (green/yellow) wires to the cable entry
gland terminal block by means of inserting the
wire conductors into the terminal block as
follows :-
The conductor of the wire coloured brown shall
be connected to the terminal marked (L), the
conductor of the wire coloured blue shall be
connected to the terminal marked (N) and the
conductor of the wire coloured green and
yellow shall be connected to the terminal

GENERAL MAINTENANCE

7. Ensure that all connections are secure and
close machine electrical housing and secure
with tool required.
SOLUTION TANK
Flush the solution tank and pump through with 10
litres of hot water. Check the filter and clean if
necessary. If damaged or compressed, unscrew
the filter and re-shape or replace as necessary.
DO NOT store hand tools, cables or hoses in the
solution tank as this may damage the filter.
RECOVERY TANK
Flush through with clean water and thoroughly
clean the vacuum filter. Remove soil and lint
build-up inside the filter screen in the recovery tank.
Lint should be cleaned off so that airflow is not
impeded. Check that the ball float moves freely
within the filter housing. If fitted, clean the drain
valve using a small soft brush to clear any debris or
sediment from the drain valve seal. Lubricate the
drain valve shaft, slide and elbow connection with a
suitable oil or maintenance spray. Check the waste
tank lid seal and also make sure the inlet elbow
inside the waste tank is tight and pointing away
from the vacuum shut-off filter.
WAND, HAND TOOLS AND HOSES
Inspect the carpet wand and hand tool for sharp
edges or damage (if accidentally dropped).
Check the spray jets for debris, correct alignment
and spray pattern. Clean if necessary using only a
soft bristle brush - DO NOT use metal or wire.
Rinse the vacuum hose with hot water to prevent
soil build-up.
Check all nuts and bolts and tighten if
necessary
Pay particular attention to the handle, base-plate
and wheel axle shaft securing bolts.
Always keep the machine clean inside and out.
WARNING! FREEZING
PROTECTION
If your extraction machine is exposed to freezing
weather with solution in the components, the
solution will FREEZE and in most cases
SERIOUSLY DAMAGE the machine. To avoid
damage, consider the following in the winter
season. When the machine is not in use, store it in
a heated building. This is particularly important in
the case of the WAND and HAND TOOL, which are
fitted with brass valves. To avoid freezing between
jobs, pump out all the cleaning solution from the
machine, wand and hand tool and make sure the
wand and hand tool are insulated from the vehicle
floor (wrap in a blanket or tarpaulin).
