Ground Fault Circuit Interrupter IMPORTANTAs of January 1994, a Ground Fault Circuit Interrupter (G.F.C.I.) is required for all electricalspa and hot tub installations. The National Electrical Code also states that a service disconnect must be conveniently located near the spa equipment compartment but a minimum of 5 feet away. A G.F.C.I. can be used for this purpose.

G.F.C.I. LINE-IN WIRING Verify that the spa is supplied by a dedicated circuit with no other appliances or devices connected to it.

Verify that the black and red supply wires feeding the G.F.C.I. are connected to a properly sized circuit breaker. Also verify that the white wire is connected to the neutral bar and the green or bare copper wire is connected to the ground bar.

Proper wiring of the G.F.C.I. is essential. Inside the G.F.C.I. enclosure, the black supply wire should be connected to the LINE-IN #1 terminal and the red supply wire to LINE-IN #2. The white wire is to be connected to the neutral bar and the green or bare copper wire to the ground lug inside the G.F.C.I. enclosure.

G.F.C.I. LINE-OUT WIRING FOR 240V 3-WIRE CIRCUIT A 240V 3-wire circuit may be used for spa installations if the system does not operate any 120V components. Under these circumstances the white load neutral wire is not required.The black wire of the cable supplying power to the spa controller should be connected to LOAD-OUT #1, the red wire to LOAD-OUT #2 and the green wire to the ground lug inside the G.F.C.I. enclosure.

G.F.C.I. LINE-OUT WIRING FOR 120/240V CONVERTIBLE SYSTEM 3/4-WIRE CIRCUIT If the spa is equipped with a 120/240V control system, a white load neutral wire is required in addition to other three wires referenced above. The white load neutral wire must be connected to the LOAD NEUTRAL OUT terminal. Proper installation of the neutral wire is essential for system operation. If not wired correctly, the G.F.C.I. will trip when a 120V component is turned on.

SPA CONTROLLER SYSTEMThe Spa Controller system package consists of the following:

A Topside Controller with push buttons to control devices such as pumps, an air blower or other auxiliary equipment, a light and a heater. The Topside Controller is designed for installation on top of the spa or tub. Topside Controller features include:

o Back lighting

o Status indicating LEDs

o Raised nibs for operation by touch

o Up and down buttons to change temperature settings

o Temperature and functionality display

A Relay Pack/Power Control designed for installation below the spa’s skirt. It includesthe following features:

o 120/240 VAC power input

o Outputs for devices such as pumps, blower, light, ozone and heater

o Signals from sensing switches

o Signals from temperature sensors

o An RJ45 Communication Cable to connect the Topside Controller and the Relay Pack/Power Control

Two Temperature Sensors. One is installed in spa water to monitor water temperatureand the second is installed on the heater surface to provide overheat/freeze protection.

SYSTEM DETAILS The system has been designed to meet the following conditions under all circumstances:

The heater can only turn ON after the pump has been ON for five seconds and the flow sensing pressure switch is closed.

After the heater is shut OFF, the pump MUST continue to run for one minute. Do not disconnect the main power until this occurs.

When the water temperature is lower than the set point, the low speed of the jet pump will automatically turn ON; the pressure switch will close, then the heater will turn ON after five seconds.

The ozone generator will turn ON only when the jet pump is running in low speed. The ozone generator will shut OFF if the jet pump is switched to high speed.

10

Page 11: DSC Installation Service Manual AR 7-02-08 no sketch

SYSTEM MODES The system has four operational modes as detailed below. Normal Operation

In normal operation, upon pressing the Jets button, the pump will operate continuously for 30 minutes, it then cycles to go on and off with the heater to maintain the set temperature. To reactivate the pump for another 30 minutes, press the Jets button again. (Note: The AUX 3 Jumper must be ON for the heater to automatically shut off when the pump is switched to high speed.) Pump Hi, Aux and light will also timeout 30 minutes after activation. The jet pump and heater will continue to cycle and maintain the set temperature. The jet pump will always run for one minute after the heater shuts off. “If the Pressure Switch does not close when the pump comes on, “FL” will be displayed and the system will shut off the pump after 5 seconds. It will make four additional attempts,turning on the low speed pump for 5 seconds every 20 seconds. If the pressure switch does not close after five attempts, an alarm will sound and the system will not be operational.”Freeze Protection Mode When the freeze sensor detects temperature below 45°F (7°C), the unit will go to freeze protection mode and turn ON the low speed pump followed by the heater. The display will alternate between the spa temperature and “Fr” at 2 second intervals. The low speed pump and the heater will stay ON until the water temperature reaches 50°F (10°C).

If the water temperature goes below 36°F (2°C), the low jets pump and the heater will bothshut OFF to protect the spa components and an alarm will sound for approximately five minutes. A device connected to the AUX output will continue to be operational in this mode.

Overheat Mode & Manual ResetWhen the water temperature is higher than 112°F (44°C), the display shows “HI”. The heater is shut OFF and an alarm begins sounding at fifteen second intervals. When the temperature falls by 5°F (3°C) to 107°F (41°C) the display stops showing “HI”. Press any button to shut off the alarm. The heater remains OFF until the temperature goes below its set point. If the freeze sensor temperature reaches 120°F (49°C), all outputs stay off even if the temperature falls below the set temperature until a button on topside is pressed (i.e. Manual reset).However, if the temperature reaches 45°F (7°C), the low speed pump and heater will go on.

Filter Cycle Mode & Purge Cycle The filter cycle begins when the main power is first applied and after the system self-diagnostics are completed. The purge cycle goes on for 15 seconds. The filter cycle runs twice in 24 hours and the cycle time is programmable by the user from 1 - 12 hours.

NOTE: To prevent the start of the initial filter cycle when the system is powered up, press and hold the pump button while power is being applied.

To put the filter cycle in program mode, push and hold both the temperature UP & DOWN buttons at the same time for 3 seconds. The display will start flashing the presently programmed filter time. If no action is taken by pressing the UP or DOWN temperature

11

Page 12: DSC Installation Service Manual AR 7-02-08 no sketch

buttons within 5 seconds, the unit will leave the program mode and revert back to normal run mode. While in the program mode, the filter time can be increased or decreased by one hour each time the UP or DOWN button is pushed and stops upon reaching the 1 hour minimum or the 12 hour maximum limit. Pushing any of the other buttons except the temperature UP & DOWN will take the unit out of the filter cycle program mode and save the present settings.

The filter cycle is factory set for a 2-hour duration. During the filter cycle “FC” and the water temperature are alternately displayed on the Topside Controller. Also, the low speed jet pump and ozone generator are both ON. The user can activate the high speed jet pump at any time, but the ozone generator will shut OFF. Upon disconnecting power, the filter cycle goes back to the factory default setting of 2 hours. If a different filter cycle duration is desired, reprogramming is needed. The program will not take effect until the next filter cycle.

TOPSIDE CONTROLLER DISPLAYSystem self-diagnostics run whenever power is applied to the System. The system checks for the connection to a Topside Controller. If the connection is NOT verified, spa operation is not possible.

When a Topside Controller is detected at power up, all segments of the Temperature Display and Status LEDs illuminate for two seconds. The default water temperature setting is 100°F (38°C). The displayed temperature will be shown in either degrees Fahrenheit or degrees Celsius. This is determined by the setting of the TemSel jumper setting on the spa controller circuit board. The temperature shown on the display is the water temperature as measured from the sensor in the spa.

Installation Instructions STEP 1: INSTALL SPA TOPSIDE CONTROLLER

To mount the topside controller you will need to locate a flat area around the rim of the spa and cut a hole for the bezel base and cable to fit through. A cutout template is furnished for your convenience.

Note: Make sure to choose a location that allows the 6’ cable to easily reach the controller system box.

Once the hole is cut, clean with a 50/50 mixture of isopropyl alcohol and water around the area so that all dust and contaminates are removed. Peel the paper backing off the bottom bezel rim exposing the adhesive. Feed the cable through the hole and place bezel over the hole pressing it firmly and evenly to get good contact.

STEP 2: INSTALL SPA CONTROLLER SYSTEM

1. Find a sturdy location to mount the spa pack. It must be close to the heater so as to minimize the wire length between the control box and the heater.

2. Disconnect the two screws holding the spa pack cover and pivot it back to open. Thecover can be removed from its hinge, if desired.

3. Determine the type of input power (120/240 VAC US or 230 VAC Europe).

For input power connection details, see Step 3. Also refer to the attached applicableConnections Diagram CD-1 (120 VAC), CD-2 (240 VAC) or CD-3 (230 VAC, Europe).

For setting jumpers inside the spa controller, refer to the Jumper Settings section below and to the applicable Connections Diagram (CD-1, CD-2 or CD-3) as noted above.

4. Set jumpers J12, J19, J22 and J26.

For 120/240 VAC US operation (default) - Jumpers are connected J12 to J26 and J19 to J22.

For 230 VAC Europe, only one jumper is needed, connected from J12 to J19.

If power to the relay pack is 240 VAC, use only a 240 VAC heater. For 120 VAC input, the heater must be 120 VAC.

The Pump, Ozone and Aux/Blower can each be jumpered as needed to operate on 120/240 or 240 VAC, depending on their requirements, when the input is 240 VAC.
