Water Drainage System

General Guidelines For Model 636
It is advisable to drain the RV, marine vessel or mobile unit
after most trips in order to maintain a clean, fresh water
system while also offering frost protection in the winter.
For extended periods between use, add sterilizer as a
backup. Draw some sterilized water through the faucets
and outlets and leave to activate for a couple of hours.
Afterward, draindown water system again and leave empty
and sterile for the next trip.
Floë works on a sealed system to build up the air pressure
to 15 psi. Should there be any air leaks, Floë will not be
able to build up pressure and it will prevent a draindown.
A typical draindown occurs when:
• Floë is properly connected;
• the blue shutoff valve is in the open position.
• the fresh water and hot water tanks have been drained.
• all water tank dump valves and all faucets and outlets are
closed again to seal the system and the toilets have not
been flushed.
Additionally, make sure the system is set to draw water
from the onboard water tank and not the city water inlet. It
is only then that air can be inserted and pressure will rise
to the prescribed amount to push water out of the system.
When Floë is switched on, the motor should only run for 30
to 60 seconds before reaching 15 psi and shutting off. This
time will change slightly after draining the first pipe leading
to the first faucet. As water is being removed, more air
will be inserted to fill the space. Floë will now take slightly
longer to build up pressure for each faucet and outlet that
are drained.
Model 636 Operation
NOTE:
Reference figure 9 during the operational
procedures.
1.
Manually drain water tanks and water heater and close
dump valves for all.
2.
Set valves to bypass water heater, as if using antifreeze
for the system.
3.
Close all faucets and outlets to seal water system
(Fig.9)
. Make sure the system is set to draw water from the
onboard water tank and not the city water inlet. Make sure
the city water inlet is closed and sealed. Do not yet
flush toilets.
4.
Open the blue shutoff valve under Floë and switch on
the Floë unit to push compressed air into the system.
Once 15 psi is reached, the motor will stop. This takes
about 30 to 60 seconds. If it takes longer than 90 seconds
for the motor to stop, switch off Floë and consult the
Troubleshooting section.
5.
Go to any faucet and open it. The compressed air will
push out the water until only a spray mist of water and air
remains. Floë will automatically restart to help push out any
remaining water.
6.
Once drained, close the faucet.
7.
When 15 psi of pressure has been reached again, the
Floë motor will stop. This will take about 30 seconds for
every outlet.
8.
Repeat steps 5 and 6 for all remaining hot and cold
faucets and showers inside and out. Showers or faucets
may have mixer valves and therefore two pipes leading to
them, both hot and cold. Both need drained, so remember
to switch to cold and drain and then over the hot side
and drain.
9.
Drain water tank-fed toilets by pushing down the flush
handle or pedal.
10.
Residual water can be drained from the water heater
by building up pressure and reopening the valves that
bypassed the water heater and opening the outside dump
valve. After draining the water, again set valves to bypass
water heater.
11.
When finished draining the main system, build up
pressure again and pull out the city water filter plug outside
and drain any residual water. When removing the filter,
remember to step out of the way of spraying water. It
may be necessary to switch to drawing water from the city
water main.
