b When repairing, be sure to provide spatial distance between R752 to R765 and C723 to C729.
R752 to R765 become hot when there is a problem.
As a measure to deal with the heat of R752 to R765, attach GLASS TUBE to C723 to C729 for products with serial num-
bers starting from the ones indicated below.
Do not attach GLASS TUBE to products with earlier serial numbers.
Be particularly careful when repairing products on which no GLASS TUBE are attached.
＜組立のご注意＞
b 修理の際は、R752 ∼ R765 と C723 ∼ C729 の間には、必ず空間距離を設けてください。
R752 ∼ R765 は、異常時に高温になります。
R752 ∼ R765 の高温対策として、以下のシリアル番号以降の生産品には、C723 ∼ C729 に保護用の GLASS TUBE を
付けています。
それ以前の生産品には、GLASS TUBE を付けていません。
