Vent Connection - Meiko K-200 Owner's Installation, Operation And Maintenance Manual

3.6 Vent Connection

IMPORTANT
In some cases, local codes dictate that
ventilation connections be made only by a
certified HVAC professional.
CAUTION
All aspects of the ventilation system must be
corrosion-resistant, frost-free and protected
against freezing temperatures (32°F/0°C or
lower). Freezing temperatures inhibit proper
operation and can damage internal
components.
Meiko K-Tronic series warewashers are
designed for use with a single-point, indirect
ventilation connection. The machine includes
a powered vent that is adequate for short,
vertical runs (10'/3m or less). For longer runs,
it is necessary to provide a powered fan for
the system (for instance, mounted on the roof)
to provide adequate airflow.
CFM ratings for the vent system, as well as
construction details, are provided on the
engineering drawings supplied with the
machine. At the time of installation, the vent
should be in place.
1. Check that the exhaust vent is correctly
positioned above the machine's fan. See
Figure 3-6. Note that the vent should NOT
be connected directly to the machine so
that room air can be drawn into the vent.
2. If the exhaust vent is powered, check the
airflow
anemometer. The CFM rating of the vent
should match the CFM rating specified on
the factory-supplied engineering drawings.
3. If the vent is constructed according to the
engineering drawings, it will include a
1"(25mm)-wide "gutter" along the bottom
edge to collect condensation. If desired,
this condensation can be drained directly
through the top panel of the machine at
the location shown in Figure 3-6.
A 1/4" dia. stainless steel tube is recom-
mended for this purpose. Note that the
drainage tube should be installed on the
side of the vent AWAY from the control
panel as shown in Figure 3-6.
After installation, the seams between the
tube, vent and machine should be sealed
with silicone sealant.
