A qualified and licensed electrician in accordance with the National Electric Code (NEC)
Article 680, Canadian Electric Code, and with any local codes must accomplish the
electrical installation.
All connections must be made according to the electrical installation label on the outside
of the control box (see page 12). Follow the instructions from the label if they are different
than the instructions in this manual. If your electrician is not absolutely sure how to
connect your system correctly, call your local dealer. Any mistake may be costly and void
your equipment warranty.
The GFCI (Ground Fault Circuit Interrupter) is a mandatory electrical safety device
required for all portable spas and hot tubs as specified in the National Electrical Code
Article 680-42. The GFCI in your particular installation may be installed at the
electrical service panel, a separate sub-panel or built into your Hydro-Quip System.
Your spa equipment requires a DEDICATED CIRCUIT. No other appliances or lights
can be on this circuit. Refer to equipment data label for power supply requirements of
your spa equipment.
Use copper conductors ONLY. The ground must be sized following the National
Electric Code, Table 250-95.
For Power conductor size, refer to the National Electric Code Table 310-16.
NOTE: Due to the electrical requirements of some models, it may be required to
SPLIT the incoming electrical service to accommodate the GFCI Circuit Breaker
limits. Contact your electrician if you need additional information on this topic.

Universal Systems require a Neutral wire therefore the service required is as follows: 120-volt
systems require a three-wire electrical service including ground, consisting of Line 1 (Black),
Neutral (White) and Ground (Green). 240-volt systems require a four wire electrical service
including ground, consisting of Line 1 (Black), Line 2 (Red), Neutral (White) and Ground
(Green).

ELECTRICAL INSTALLATION

If your system was configured to include a 120VAC power cord, ensure that the proper
receptacle has been installed (a dedicated circuit is required). DO NOT under any
circumstances modify a 20 Amp plug to fit into a 15 Amp receptacle or use an extension cord.
Doing so will create hazardous conditions and/or void the warranty.

Power from main breaker panel to service disconnect within line-of-site of the
spa to portable spa control equipped with buit-in GFCI.
Refer to the System Data Label for equipment voltage and maximum amperage draws.
Install proper size Ground Fault Circuit Interrupter (GFCI) or circuit breaker, then proper sized
wiring and bonding wire. For Power conductor size, refer to the National Electric Code Table
310-16. For Ground conductor size, refer to the National Electric Code Table 250-122.
A bonding lug has been provided on the control box to allow connection to local ground points.
To reduce the risk of electrical shock, a solid copper bonding wire should be connected from this
lug to any metal ladders, water pipes or other metal object within 5 feet of the spa.
WARNING - BE SURE THAT YOUR POWER SUPPLY CIRCUIT CAN ADEQUATELY HANDLE
THE AMPERAGE YOU SELECT.
The control input power wiring may have been provided. Following NEC and local codes in
effect at the time of installation, connect (refer to wiring diagram located on the inside of control
hinged cover) the Black wire to input Line 1, Blue wire to input Line 2 (if applicable), White wire
to Neutral and the Green wire to ground.

When a GFCI circuit breaker is used in the installation of your spa, it is important that it has
been properly installed. Often this component has been improperly installed causing the breaker
to trip the instant the system is turned on. Below is an illustration of a typical GFCI breaker
installation.
WARNING: Refer to Circuit Breaker Manufacturers installation instructions.

LOW-FLOW SYSTEM CONFIGURATION
1. Locate the connection point
for the flow switch.
2. Connect the flow switch
connector to the connection
point making sure all pins are
covered.
3. Route the flow switch cable
through an empty slot allocated
for small cables/cords.
The system may come equipped with a “Low-Flow” heater assembly and flow
switch. When a flow switch is supplied the connection of the switch to the
system is directly to the PCB (Printed Circuit Board). Below are details on
where and how to connect the flow switch to a CS7506 control system. The
connection point may differ on other control systems. When in doubt refer to
the wiring diagram location inside the control box cover for details and connect
accordingly to the pressure/flow switch connection point.

If your system includes a Versi-Heat remote heater, see illustration below to see which layout
best fits your particular installation.
The heater can be installed vertical, horizontal or at an angle in the pumps
discharge plumbing (providing position DOES NOT allow air pockets to form
inside the housing). The heater can be installed up to 5-feet from the control
system, which is connected via a black 3-conductor and black 6-conductor
cord to the black receptacles provided at the control box..
IMPORTANT: It may be necessary to adjust the pressure switch (located
inside the heater enclosure) in some cases.
VERSI-HEAT CONSIDERATIONS
Pressure Switch Access

A placard has been provided with each control to eliminate problems encountered when the
spaside access hole is too large. Use the illustrations and instructions below to install the
spaside control provided with your system.
Step 1 - (If control cutout already exists, determine if
placard must be used. If existing cutout is sufficient,
disregard step 1.) Choose a location for the
spaside control. Using the template provided,
cut out a 2 5/8” X 6 3/8” hole. Clean area and
insert spaside control making sure tab locks
are rotated inward. (If placard is required, position and
secure using a water resistant silicone sealant.)
Step 2 - Rotate lock tab screws on face of
control clockwise to engage locks and secure
control into place.
Step 3 - Remove protective film from display
windows, clean control surface with rubbing
alcohol and apply label. Connect spaside
control plug to circuit board as shown.
