Caldera Highland Series User Manual

The Sleep Mode operation is a feature that minimizes pump operation during evening hours.  For example, if Filter Cycle 1(F1) is set to activate at  
8:00am, by default, Filter Cycle 2 (F2) will be set to activate at 8:00pm (12 hrs. later).  During 8:00pm to 8:00am, if the spa should call for heat, the 
pump and heater will activate to heat the spa.  However, when in Sleep Mode, should the spa call for heat, the pump and heater will be

suspended until the activation of Filter Cycle 1 at 8:00am, to minimize pump activation during evening hours.  NOTE: If water temperature drops below 80 degrees,
pump and heater will automatically activate to prevent temperature from dropping further.

To activate the Sleep Mode feature, press and hold “TEMP 

▲ “ and “TEMP ▼“ buttons together for 3 seconds. This will activate the feature and override the normal filter

cycle operation.  When these buttons have been engaged, the Sleep Mode icon will illuminate on the control panel display, indicating the feature is active.  To deactivate
this feature, simply press and hold the specific buttons in the same manner once again. 

The Air Control(s) located next to your spa-side control panel allows you to change the power of the jets by regulating the amount of air that is mixed with the water
coming out of the jets.

Magna

TM

Jets – The larger jets in your spa allow you to re-direct the jet stream by changing the position of the nozzle.

You can also regulate the force of the massage by rotating the jet face clockwise to reduce the force or counter-clockwise to increase the force. Notice that turning off
the flow to some jets increases the flow to the other jets. To avoid damage to your spa’s plumbing and components, do not turn off more than half of these jets at
the same time.

MagnaSsage

TM

rotating nozzles are available from your dealer, to replace the directional adjustable nozzles in the Magna Jets.

Euro Directional Jets – The small euro jets deliver a direct, precision massage. You may also purchase Euro-Pulse

®

assemblies from your dealer that would replace the

Euro directional jets to provide a pulsating, rotary massage. This can be accomplished by simply twisting off the Euro jet face, adding the nozzle and nozzle retainer,
then reinstalling the Euro jet face.

The diverter valve on the Cumberland

®

spa model allows you to direct the flow of water from the pump to several combinations of jets. The functions of this diverter

valve can best be learned by experimentation as follows:

1. Set all air controls to the “ON” position by rotating counterclockwise.

2. Turn on the pump.

3. Turn the handle on the diverter valve and see which groups of jets are affected. (Note that you can adjust the diverter valve to any position between the two possible

extremes to achieve the jet pressure that feels best to you.)

IMPORTANT: Your spa is not designed to provide full power to all jets when the diverter valve is in the “mid” position.

The Olympia

TM

spa is equipped with the cascading waterfall feature. It is activated by turning JETS2 and turning the valve, located on the front interior wall,

counterclockwise. The flow is regulated by turning the waterfall valve to the desired position.

It’s important to have clean water. Water maintenance is one of the least understood, yet most important areas of spa ownership. Your dealer can guide you through the
process of achieving and maintaining perfect water in your spa, given your local conditions. Your program will depend on your water’s mineral content, how often you
use your spa, and how many people use it. 

Water Sanitation is the responsibility of the spa owner, achieved through the regular and periodic (daily, if necessary) addition of an approved sanitizer. The sanitizer will
chemically control the bacteria and viruses present in the fill water or introduced during use of the spa. Bacteria and viruses can grow quickly in undersanitized spa
water.

The water’s chemical balance and pH control are also the responsibility of the spa owner. You’ll have to add chemicals to maintain proper levels of Total Alkalinity (TA),
Calcium Hardness (CH) and pH. Proper water balance and pH control will minimize scale buildup, extend the life of the spa, and allow the sanitizer to work at an
optimum level.
