22. Never fail to perform periodic inspection.
Check regularly Earth Leakage Breaker (ELB) and Independent Overheat Prevention Device
(IOPD) which they are key part/Device for the safety of this Equipment.
Refer to Chapter 6. Maintenance Method on page 61.
23. Pay attention to the following when operating the product with the exhaust
damper fully opened.
With the exhaust damper fully opened, the set temperature cnnot be reached.
Note also that the set temperature may not be reached in cases other than the dampler fully
opened. The customer is requested to check this in line with the variable speed before
operation.
24. Take care for possible degradation of performance when using the cable port.
When a measurement sensor or a probe is inserted into the cable port close the cable port
cover as much as possible and completely seal to any gaps with heat-resistant packing or
sealant. If seal is insufficient, the temperature characteristic, cleanliness or other performance
will degrade.
Use an optional silicon plu
g (with one hole) as necessary. See”P.70 List of optional settings”.
25. Smoke (odor) may generate when you operate the unit for the first time.
When you operate the unit for the first time, the bonding material of the heat insulation material
may burn and generate odor, which, however, does not indicate a malfunction of the unit. Odor
will not generate as you continue to use the unit for some time.
