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.

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.

8
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.

Option #1 Preferred Method - DRYWELL: If the existing placement of your temperature sensor
does not allow for an accurate temperature reading a drywell may have to be installed in the spa
wall. Once a location has been chosen, cut a 1 1/8” hole (cut from inside the spa). Clean excess
debris from around the hole. Use a water resistant silicone applied to the sealing surfaces and
insert the drywell into the hole. Tighten the drywell nut ( DO NOT over tighten). Insert
temperature sensor into drywell and insert grommet as shown below. Allow silicone to cure for
24-hours.

Using a suitable 2“ diameter hole-saw, cut a hole in the spa wall. Cut from inside the spa wall
toward the outside to prevent splintering the inner surface. Remove any insulation material from
around the hole (at least 2“) at the outside spa wall. Install the gasket onto the light body and
install the light into the hole. Take care not to over tighten the nut securing the light body.
(Silicone sealant may be used in place of the gasket. Allow adequate time for sealant to cure before filling the
spa.)

Using the “System Operation Manual” provided with the unit, complete the following procedures:
1) Read and familiarize yourself with the system Operation manual.
2) Unplug the power cord (120-volt system only) or turn the electrical power “OFF” at the service or
breaker panel (120 or 240 volt permanently connected units.)
3) Open all WATER shut-off valves.
4) For spas equipped with a hose bib or drain valve, make sure that it has been closed.
5) For spas equipped with in-line or pressure water filters, make sure that the filter nut, housing drain plug,
and air relief valve are closed and tight.
6) Using a standard water hose, fill the spa with fresh tap water to the level recommended by the spa
manufacturer.
7) Inspect all plumbing connections and lines for any sign of water leaks.
8) Close all AIR control valves. WARNING: Do not confuse with WATER shut-off valves.
9) Plug the unit into the proper outlet (120-volt system) or turn on the breaker at the electrical service
panel (240-volt system).
10) Adjust temperature to the lowest setting.
11) On units with a Ground Fault Circuit Interrupter (GFCI), check the GFCI by pressing the “Test” button
on the face of the device. The “Reset” button should pop out. The equipment should not operate.
12) Activate the equipment by pressing the “Reset” button on the GFCI. (If the jet pump(s) or blower is
operating, switch them off).
13) Press the “JET PUMP” switch to run on high speed. Allow to run until you achieve a strong, steady
water flow (free of air bubbles).
14) On systems with a pressure filter, bleed off the trapped air by opening the Air-Relief valve. You will
notice a steady flow of water when the air has been bled completely.
15) Switch the “JET PUMP” off.
16) If equipped, switch the “AIR BLOWER” on to verify that it is working, then switch it off.
17) If equipped, switch the “LIGHT” on to verify that it is working, then switch it off.
18) If equipped, switch the “AUXILIARY PUMP” on to verify that it is working, allow to run until all air is
evacuated from the plumbing system, then switch it off.
19) Adjust temperature to the desired set point for comfortable use of the spa. The pump low speed and
heater will activate until the set point has been reached.
It is now time to turn over operation of the spa to the homeowner. See next section for basic
troubleshooting tips.

If your system is equipped with a pressure switch, the function of the pressure switch is to turn the heater off if the
pump stops operating or if there is a restricted water flow (dirty filter, obstruction in the spa plumbing etc.).
The pressure switch has been preset at the factory to operate properly with your spas specific plumbing.
Adjustment or other service may be required if you observe a flow related problem (FLO or FLC on spaside
display). If adjustment is required, follow the next steps carefully.
IMPORTANT: After any pressure switch adjustment, it is important to test the control by
turning on the pump low speed and heater. While operating, unplug the pump, the heater
must turn off. If the heater stays on, plug the pump back in and readjust the pressure
switch to achieve proper operation.
1) With power to system turned OFF, remove the wires from the pressure switch terminals
(secure wires safely to prevent any chance of electrical shock).
2) Use temperature adjustment key to move “set point” temperature to its lowest setting.
3) Turn power to the system ON and activate the low-speed pump.
4) Place an Ohmmeter across the pressure switch terminals to verify an OPEN circuit.
5) Rotate the pressure switch adjustment screw counter-clockwise until the Ohmmeter indicates
a CLOSED circuit.
6) Turn pump OFF and verify that the pressure switch circuit is once again OPEN.
7) Turn power to the system OFF and reconnect pressure switch wires. Reapply power to the
system and operate the spa or hot tub as normal.
