※Please supply the air more than min. usable air capacity
without fail.

④Please set up hot-air temp. by the temp. setting
up down key, and close the input terminal of theheater ON/OFF S7-S8.

Present temp. is displayed at the hot-air temp. PV display andoverheat prevention temp. PV display. And 0 is displayed at
the hot-air temp. SV display. (First time)

Hot-air lamp (Orange) and heater lamp (Green) are lighted
and hot-air operation is started. B-sensor temp. rises too assoon as hot-air temp. rises.

※Hot-start temp. SV display is not displayed at all.
※When the control of the heater is started heater lamp flickers.

● Soft start operation
Heater output is controlled from the operation start postperiod because over-shoot of the discharge temp. isrestrainedeven in which setting temp. area. Temp. rise in the operation is monitored by this control. And, cver-shootof the discharge temp. is reduced substantiallyby the max. temp. rise width for one second is controlled. (Start time
may become long by the area of temp.)

Operation stop
Please turn OFF (○) main SW. Or, please open the input terminal of heater ON/OFF S7-S8. At this time, it
is no problem even if the supply of air is stopped simultaneously. But, please defend the following attention.
〈Attention 〉 Please do not increase supply air sharply for cooling if operation is stopped in the case that SH31 is used in theneighborhood of the max. temp. Heater insulator is damaged ．
〈Attention 〉 The cooling operation is necessary in the case that the outlet of Spot heater is downward from level. Pleasesuspend the supply of air after discharge temp. is cooled to 70C after the main SW was turned off or the input
terminal of heater ON/OFF S7-S8 was open.

by the temp. setting up down key, and close theinput terminal of the heater ON/OFF S7-S8.

Hot-start lamp (Orange) is lighted and the present temp. isdisplayed at the hot-air temp. PV display and overheat
prevention temp. PV display. And 0 is displayed at the hotair temp. SV display and hot-start temp. SV display. (First time)

Hot-air lamp (Orange) and heater lamp (Green) are lighted
and hot-start operation is started.

※Heater lamp is lighted when the control of hot-start temp. wasstarted.
※Temp. of A-sensor rises a little at the time of hot-start operation
because the electricity is flowing to the heater.

⑤Please supply air to the heater after the input
terminal of the operation mode S5-S6 is open.
Hot-start lamp and hot-start temp. SV display are
not lighted and usually operation is started.
At this time, the overheat prevention temp. PV display displays theactual temp. of B-sensor because hot-start temp. that was set up isdisregarded to change to overheat prevention temp.
※Please supply the air more than min. usable gas capacity
without fail.

Please open or close the input terminal of operation
