Process 5
Cooling
1. Upon completion of automatic soldering, use a 
fan or other device to forcibly cool the PCB. This 
helps prevent the Relay and other components 
from deteriorating from the residual heat of 
soldering.
2. Fully sealed Relays are washable. Do not, 
however, put fully sealed Relays in a cold cleaning 
solvent immediately after soldering or the seals 
may be damaged.

Cleaning
Refer to the following table to select the cleaning 
method and solvent.
Cleaning Method
G7S G7SA
Neither boiling cleaning nor immersion cleaning is 
possible. 
Clean only the back of the PCB with a brush.
Process 7
Coating
1. With the G7S or G7SA, coating will penetrate 
inside Relays and damage the contacts. 
Therefore either do not apply coating at all or 
apply the coating first, before mounting the 
Relays.
2. Be very careful in selecting the coating material. 
Depending on the type of coating selected, it may 
damage the Relay case and chemically dissolve 
the seals, causing them to lose their sealing 
capability.
3. Do not secure the entire Relay in resin, or the 
Relay's characteristics will be changed.
Do not exceed the maximum value for the 
coating's ambient operating temperature.
