Installation/Operation Method
Connecting the Drain Hose
1. Remove the rubber plug from the outlet of the
water drain port ②.
2. Route the water drain hose ⑤, and insert it into
the water drain port ②. Then tighten them
with the attached hose band ⑥ firmly.
3. When discharging the boiler water, the temp of
the drained water could exceed 60℃. Worker
could be burned. Do not touch such water
carelessly. Water should be drained to a place
away from the work place.
NOTE)
• The water drain hose may be routed in from the
right/left sides of the main unit. Route such
hose in from convenient side.
• Do not wind around the water drain hose, but
cut it to the required length for use. Take
delicate care to prevent it from being folded,
and be sure to place it below the water drain
port of the main unit. Any piping possibly
causing water pool in the hose or at the outlet
of the hose should be avoided, because the
resistance in discharging water increases.
Flow of water could also be reversed.

Operation Preparation
Open the front door of the main unit, and remove
the rubber rings fixing the micro-switch and the
float in the float tube (fixed to prevent the float
from coming off in transit). (Be sure to remove
this, for non-load combustion is feared.)
Operation Method
1. Open the tap.
2. Check if the manual cock for discharging boiler water is closed.
3. Turn ON the power switch (shared by earth leakage breaker) in the front.
4. The distilled water pooled in the tank can be sampled by opening the tap.
