SELECTING THE VOLTAGE FOR YOUR SPA
Your spa is designed to operate at either 115 or 230 volts, 60 Hz, unless it is the Olympia model which requires a dedicated 230 volt power supply. When the spa is
connected to 115 volts, the heater will provide approximately 1000 watts of heat only when the pump is operating in LOW speed and the thermostat is calling for heat.
When the spa is connected to 230 volts, the heater will provide approximately 4000 watts of heat when the pump is operating in LOW or HIGH speed and the thermostat
is calling for heat.
All electrical connections must be made in accordance with the wiring information contained in the electrical control box or on the back of the field wiring access panel
of the equipment module.
115 VOLT INSTALLATION
Spas provided with a factory- installed power supply cord are to be plugged into a grounded, grounding type, 115 volt, 15 ampere receptacle (Cumberland
TM
model) or
20 ampere receptacle (Cascade model). No other electrical appliance or fixture can be used on this circuit.
IMPORTANT: Under
NO
circumstances should an extension cord be used. Use of an extension cord will seriously degrade the performance of the equipment module
and can create an electrical hazard.
230 VOLT INSTALLATION
When using 230 volt power supply, installation of a 50 amp dedicated circuit is required. Your spa must be hardwired direct to a GFCI-protected subpanel by a licensed
electrician. A wiring diagram is provided inside the equipment module showing where the connections are to be made.
ELECTRICAL REQUIREMENTS AND PRECAUTIONS
Your Caldera
®
spa has been carefully designed to give you maximum safety against electrical shock. Connecting the spa to an improperly wired circuit will negate many
of the spa’s safety features. Improper wiring may also cause electrocution, risk of fire, and other risks of injuries. Please read and follow the electrical installation
requirements and instructions for your spa completely!
115-230 VOLT CONVERSION
(CASCADE & CUMBERLAND MODELS ONLY)
Refer to the following instructions to convert your 115 volt Highland series spa to a 230 volt spa.
NOTE
: Converting the spa to 230 volts operation should only be done by an authorized service agent or a qualified electrician.
The conversion requires a subpanel (230 volt) which may be purchased from your Authorized dealer. Ask for part # 38661
1. Disconnect the power cord from the house receptacle.
2. Remove the screws and open the equipment compartment door.
3. Remove the screws from the control box.
4. Open the control box cover.
5. Remove the power cord wires, and the power jumper wire (from line 2 and neutral) on the line side of the terminal block.
6. Locate Program Jumper JMP 1, using a pair of needle nose pliers, carefully move the jumper from pins 2 and 3 and move to pins 1 and 2 (see Figure below).
A licensed electrician must install the subpanel (available from your dealer) to supply power to the spa. The subpanel must be placed in sight of the spa at a minimum
distance of 5 feet away.
