Automatic Filtration/Maintenance
If you plan to be away, you should maintain minimum water quality by running the filter system. To do this, set
the timer to turn the system on for at least two hours each day. This will cause the filter system to turn on at a
desired time. Set the timer according to instructions on page 8 with the SYSTEM switch OFF. If you do not
want the water to be heated, turn the Temp. Control knob to its minimum setting.
If you will be away for an extended period, however, we recommend that you drain the spa (following the procedure
described under Winterizing on this page), as long periods without maintenance of water quality could be detrimental
to the spa.
Another means of maintaining minimum water quality while away for less than two weeks is to follow the procedure
outlined for winterizing your spa in a warm climate. See Winterizing. Note: We do not recommend using this procedure
if you are absent during the summer, when algae build-up is most likely.)
Always keep your spa covered when not in use to reduce heat loss and evaporation and to prevent debris from
falling in.
CAUTION: Not winterizing will cause irreversible
damage (at freezing temperatures) to the pump and/
or plumbing lines.
Note: If the spa is to be used during winter in a cold
climate, see warm climate instructions below.
In a warm climate where there are occasional freez-
ing temperatures, follow this procedure:
1. Select the HTR/FILTER mode.
2. Set the thermostat to its minimum temperature (45
°
-
50
°
F.) by turning the dial all the way counter clock-
wise.
3. Maintain a chemical balance. (See Water Quality
section.)
4. Keep the spa covered using the spa cover provided.
Winterizing
In a climate where winter temperatures are be-
low freezing, follow this procedure when the spa
will NOT be used:
1. Select the OFF mode.
2. Unplug the unit. Turn off the house circuit breaker.
(If converted to 230 V, turn off the power at the circuit
breaker.)
3. Drain the spa completely by attaching a garden
hose to the drain valve on the suction plumbing.
Then remove the hose and leave the drain valve in
the open position.
4. Remove the filter cartridges, clean them, and store
them dry.
5. Keep water and debris out by covering with a rigid
spa cover.
6. Before using the spa again, review the Operating
Instructions.
Factory Installed Redwood Skirt
Your Aero Plus spa is supplied with a factory-installed
redwood skirt which completely surrounds the spa.
The equipment access door can be opened for main-
tenance, setting the timer.
The skirt is made of kiln-dried redwood and can be
left natural to weather to it's normal light gray color
(after about three months), or you may choose to apply
a stain or clear finish. Consult your local paint dealer
for the appropriate product.
If it becomes necessary to remove any of the skirt
sections, simply remove the screws with which the
section is secured.
Note: When you remove the skirts, you will notice
the plastic covered, foam insulation blocks. These
blocks are designed to be removed when service is
required and reinstalled when service has been com-
pleted.
