D. commissioning - vertical
WARNING: The system must be lled
with water at all times once commissioned. Failure
to do so may cause the system to dry and become
damaged, resulting in personal injury, illness, and/or
death.
Do not turn on any hot water taps when ushing the
system during commissioning or maintenance. If
hot water is used, high levels of factory preservative,
chlorine, or MC1 cleaning agent may enter the hot
water tank and may cause personal injury, illness, and/
or death.
Disposable protective gloves must be worn during
commissioning of the system to protect your hands. At
the end of the procedure, wash your hands thoroughly
with soap and water. Do not reuse gloves. Dispose of
gloves in the garbage.
Filling and Flushing
WARNING: If the system cap is not
properly tightened and/or the O-ring is not clean,
system leaks may occur. Leaks may cause personal
injury or property damage. Take care not to cross-
thread the system cap during cap installation. Apply
DOW CORNING 111 silicone to O-ring and threads. Spin
system cap by hand until it stops. Then tighten with
supplied wrench 1/2 turn. If cap leaks, turn o water
and turn additional 1/4 turn. Make sure vent valve is
always open 1-1/2 turns to allow trapped air to escape
freely.
When the internal prelter is removed, ensure the
thimble lter remains in place, seated in the spigot of
the prelter cavity. Removal of the thimble lter may
permit damage to the system membrane, which may
lead to illness or death.
4
Ensure that the O-ring is seated at the lip of the external
prelter housing. Screw the external prelter housing into the
external prelter head. Tighten the connection with the
housing wrench.
5
The plumbing must be compatible with the inlet and
outlet ports of the external prelter.
6
Install the mini ball valve with plug at the bottom of the
external prelter housing.
When external prelter housing needs to be removed for
servicing (e.g. to change the lter cartridge), close the inlet
valve and depressurize the external prelter by draining the
water inside. To drain the water inside, open the mini ball valve
at the bottom of the external prelter housing. Depress the
red button on the external lter head to speed up draining. A
length of 1/4" tubing can be inserted into the port of the mini
ball valve to direct water into a drain or a large pail.
NOTE: Before installing or replacing the external prelter
housing on the external prelter head, inspect the O-ring to
ensure that it is clean and in good condition. Lubricate the
O-ring sparingly with DOW CORNING 111 silicone lubricant.
WARNING: In surface water
applications, failure to install and/or properly maintain
the external prelter cartridge may cause premature
fouling of the system and therefore, shorten the
system’s life or damage the system membrane, causing
personal injury and/or death.
