Multi-purpose steaMer Mps-250
Note: Multi-Purpose steamer models are
designed to use cold tap water.
The MPS-250 requires a direct water hookup. An
installation kit is packed inside the unit.
Note: restaurants that use the FBs-90 steamer
should utilize the same water connection provided
it is located after the iMF and/or any other water
treatment system.

iNstallatioN iNstruCtioNs
1. Install manifold/regulator assembly to the steamer
as shown using #8 bracket screws supplied.
Note: the aJa Water Pressure regulator Kit, P/N
7000235, has the capacity to feed two steamers
simultaneously (Figure 2).
2. Open the shut-off valve to allow water flow to
the regulator. Ensure that the Water Pressure
Regulator is set at 20 psi. If not, confirm that
incoming water pressure is above 25 psi and if
so, adjust the regulator by pulling softly on the
knob and turning until gauge reads desired
pressure. Push in the knob to lock.
Note: if pressure was adjusted, existing pressure
must be relieved in order to register new set
pressure.
3. Push in the outlet sleeve of one 1/4” “QD” elbow
fitting (attached to manifold) and hold for two min-
utes to purge out air in the line and allow water to
flow freely into a bucket with a steady stream.
4. Connect the 1/4” “QD” to the steamers as shown.
Turn on the steamers and allow 20 minutes to
warm up. Cycle the units 3 times and check the
pressure regulator setting. If there is a change,
adjust it again to read 20 to 30 psi and then push
the knob to lock. Your steamer(s) is ready to be
used.
CautioN
Water pressure must not exceed 30 psi (or 207
kPa). higher water pressures may cause poor
performance or flooding. to reduce water pres-
sure, install a Water Pressure regulator, and
set to 20 psi (1.4 kg/cm2 or 138 kPa). to order a
water pressure regulator from your authorized
service agency, order roundup part no. 7000235.
CautioN
This equipment is to be installed to comply with
the basic plumbing code of the Building officials
and Code administrators, inlc. (BoCa) and the
Food service sanitation Manual of the Food and
drug administration (Fda).
