before use, for correct use of the converter.
Please observe cautions stated bellow, for it contains
important information on safety.
CAUTION
CAUTION
1. Overview
The NO2/NO converter is to be coupled with a NOx gas
analyzer or NH3gas analyzer for flue exhaust. It is
converter using a special catalyst which efficiently
converts NO2in sample gas to NO.
2. Major Specifications
Catalyst : Carbon, replacement required every
8 months (when NO2concentration
is 10 ppm or lower)
Gas flow rate : About 0.5L/min.
Set temperature : 220±10°C
Thermocouple : K
Power supply : 100V AC, 50/60Hz
Power consumption : About 85VA
Material of parts that contact gas
: Ceramic, Viton, Glass wool,
SUS316
Gas inlet/outlet connection method
: Insert Teflon tube φ6 mm/φ4 mm
into Viton connection port of inner
diameter φ5.5 mm. (Withstand
pressure: 10 kPa)

INSTRUCTION MANUAL
●Installation, wiring and piping should be carried
out by professionals or suppliers. Incomplete
installation may cause fall of the device, electric
shock or fire.
●Gas analyzer should be turned OFF when wiring,
maintenance or inspection is carried out. This is to
prevent electric shock and injury.
●Use wires with proper wire rods and diameters
that meets this device. Wrong ones may cause
electric shock or fire.
●Do not insert metal rod or fingers to the power
supply terminal. It may cause electric shock.
●Remove any metal objects such as wristwatch
while operating maintenance or inspection. It may
cause electric shock.
●Use pipes with proper material and joints stated in
the instruction manual. It may cause gas leakage.
●Use replacement parts that are specified by the
manufacturer. Otherwise, it may cause
malfunction, electric shock or gas leakage.
●Do not touch the converter section, due to high
temperature. Wear protective gloves while
exchanging catalyst. It may cause burn injury.
Model: ZDL03
Precautions under this mark is stated
when wrong handling may cause
hazardous situation. Possibility of
Medium level damage or injury, and
physical damage is predicted.

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 NO2/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 NO2concentration 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.
