RECOMMENDED MAINTENANCE OF 
NANAWALL PRODUCTS

Some General Considerations on all Projects:

1.

It is important that the product is installed correctly.
A poorly installed unit will not function properly.
This will cause more abnormal force or stress on
the components and will lead to premature failure.
When operating the unit, the panels should generally
be able to be moved easily by one person (except
when there are very large panels or when there are
more than 6 panels folding to one side). All locking
points should engage smoothly. There should be no
rubbing on the floor and no binding. When the unit is
closed, the reveal between panels and head jamb and
between panels and sill should be consistent. There
should be no daylight seen from the inside. Please
have all problems corrected as soon as possible by a
qualified technician.

2. From time to time, due to building movement or

settlement, a unit may need to be adjusted by a
qualified technician to compensate for any building
change.

3. It is important that a unit is operated properly.

Locking points should be gently opened and closed
and not forced. Panels should be opened and
closed in the proper manner and sequence. See the
Operation section for proper operation.

4. Periodically check for worn or damaged components

and replace as soon as possible. A unit with
nonworking components will subject the other
components to increased stress and lead to
premature failure. A unit with worn or damaged
components will compromise the performance level
expected for air and water infiltration, structural
loading and forced entry.

5. Periodically, inspect the sealant/caulking on the

exterior perimeter of the unit. It is extremely
important that the sealant/caulking remains intact
and in good condition. Trim off any old, loose caulking
and seal any gaps with a good quality caulk.

6. Check that all weep holes are clean and clear of any

obstructions. Remove debris and other foreign bodies
which have dropped into the tracks in the head jamb
and sill immediately to prevent damaging the running
carriages and guide trolleys. Clean all components as
needed.

Check gaskets for proper seating and condition.
Remove dust and any deposits from these gaskets.

7.

The finished aluminum or wood surface needs
periodic cleaning and maintenance. Its appearance
may be marred by harsh chemicals, abuse or neglect.
Frequency of cleaning depends on exposure and
needs. For aluminum surfaces, generally warm
soapy water should be sufficient. Stubborn stains
and deposits may be removed with mineral spirits.
For wood surfaces, superficial surface dirt can be
removed by washing with water and a soft-bristled,
long-handled brush. Heavier accumulations can
be removed with a mild solution of household
detergent. For all surfaces, aggressive alkaline or
acid cleaners should not be used. Excessive abrasive
rubbing should be avoided. Sealants and weather
stripping may be affected by strong organic solvents.
Superficial damage to the aluminum surface must be
touched up immediately with proper touch up paint.

8. If it is a wood product, the surface should be visually

inspected every six months or earlier, depending
on the exposure of the NanaWall unit. Periodically
repaint or restain the wood as needed. Exposure
to the environment will break down the finish and
compromise its protective features if not refinished.
