4. Installation, Piping, Wiring
(1) The main frame should be installed vertically to the
ground. Avoid installing it obliquely or laying it on
its side. Be careful not to apply load to the joints at
the top and the bottom.
(2) Pipes should be connected so that the bottom port of
converter block becomes an inlet and the top port
becomes an outlet. (Refer to “3. Outline Drawing.”)
(3) Connect power supply to the terminals indicated in the
wiring diagram. (Use type D for grounding.)
(4) Install fuse or power switch separately.
(5) Confirm the piping and wiring before turning ON the
converter.
(6) Be careful of the high temperature after turning the
power on. The temperature regulator (*) is set at
220°C. Since temperature has been factory-set, the
temperature regulator need not be operated.
(*) Setting of temperature controller for NO

/NO
converter (PXZ4TCY2-0Y100).
(a) When pressing the PV/SV key, display changes
over between PV and SV. (Usually, PV (Process
Variable) display is set.)
(b) Under SV (Set Value) display, set 220°C by pressing
the or key and determine it by the
ENT key. (200°C need be set for NO/CO
analyzer.)
(c) Run automatic tuning when temperature is unstable.
(d) The temperature controller controls converter
temperature through the SSR relay.
5. How to Replace Catalyst
CAUTION
Catalyst and filter should be replaced with new ones once
every eight months. (when flow rate is 0.5L/min or lower
and NO
2
concentration is 10 ppm or lower)
(1) Turn off the main power supply for converter.
(2) When it has cooled down, remove One touch band
from the upper joint (1) shown in Fig. 2 with a pair of
pliers or other apparatus. The lower joint (1) can be
easily removed by shifting it gradually with a
blade-edge screwdriver. Attention should be paid
not to damage the ceramic heater.
(3) Pull out the metal fitting plates (2).
[CAUTION] Place a catch pan or sort to receive the
falling catalyst (3) and glass wools (4).
(4) Place (4) at the end of metal fitting plate (long) (2),
insert it from the lower side of the ceramic heater, then
inject the new (3) from the top, using a funnel or alike.
(5) Attach new joints (1) and (5) to the heater and
reconnect it to piping, then fasten all the straps of the
bands. Turn ON the power supply.

During catalyst replacement, carefully protect your
body from a burn because the converter block is hot.
