ROUTINE DELIMING

When ScaleBlocker ® water treatment system is
used, preventative maintenance along with cartridge
replacement must be performed every 6 months. Water
conditions may require additional deliming, see chart
at right.
Use ScaleRelease (14 oz) P/N 00-854893-00013 for
deliming; 14 Oz. for counter tops, 28 Oz. required for
floor models.
The cooling water supplied to the steamer is not treated.
White vinegar poured down the cavity drains will prevent
scale from forming in the drain system. Pour one
cup (8 Oz.) of white vinegar down each cavity drain at
the end of the day. Make sure the unit has been off for
5-10 minutes before adding the vinegar to the drain.

CARTRIDGE CHANGE/REPLACEMENT SCHEDULE

NOTE: The Scale Blocker pm kit (i.e. filter) must be replaced every six months, (every twelve months
for K-12 180 Day Schools). In addition, the equipment needs to be regularly delimed based on the water
hardness at the location (see chart above). Failure to perform all required preventive maintenance
will void water related warranty on the equipment.
• Gallon capacity of filter cartridge will vary according to flow rate, inlet pressure and local water
conditions. Replace cartridge immediately if outlet pressure gauge is less than 20 psi or before
end of capacity life (Maximum cartridge operating life 6 months). Fluctuations of pressure
will occur and can be seen at gauge during heavy and light usage. Inspect gauge during worst
case heavy water usage (Fig. 1, Item 7). It is recommended to change PRIOR to nearing end
of cartridge life.
• Failure to replace cartridge every 6 months will result in hard scale build up in the steam
generator. Pitting, rusting and discoloration will occur from Chloramines and Chlorine
in water supply and will damage your steamer.
• This filter reduces hard scale build-up due to hardness or other contaminants that may be in
water.
• Hardness higher than 5 grains will result in some soft scale build-up. Routine deliming is required
to remove soft scale build-up, see deliming chart.
