5.1 Installation of coil
WARNING!
Risk of escape of media.
When a sticking nut is loosened, medium may escape.
▶ Do not tighten sticking nut any further.
Risk of injury due to electrical shock.
If the protective conductor contact between the coil and body is
missing, there is danger of electrical shock.
▶ During installation insert the plastic ring into the body journal. The
plastic ring must not project over the octagonal nipple.
▶ Check protective conductor contact after installing the coil.
Overheating, risk of fire.
If the coil is connected without a pre-installed valve, the coil will overheat
and be destroyed.
▶ Connect the coil with a pre-installed valve only.
