FOR THE ELECTRICIAN, CONVERSION FROM 120V TO 240V
Installations that do not adhere to these instructions can expose users to electric shock and will void the warranty.
The conversion of the equipment package, from a factory installed 120-
volt system to a hardwired 120/240 volt system, must be completed by a
certified licensed electrician. This procedure will convert the heater from
120 volts (1000 watts) to 240 volts (4000 watts). All other electrical
components will remain 120 volts, so it will be necessary to include a
neutral wire in the new electrical service. It will also be necessary to select
how the heater will operate, thereby dictating the size of the new
electrical service. If the heater will operate only when the low-speed
pump is running, then a 30-amp service will be used, and the #10 dip
switch will be set to the low amp position (page 11). If the heater will
operate when both high and low-speed pumps are running, then a 50-amp
service is required, and the #10 dip switch will be set in the high amp
position (page 11). Regardless of your choice, the following will also have
to be done.
1. Remove and discard the 120-volt GFCI power cord.
2. Remove and discard the white wire jumper between
J32 and J11.
3. Move #10 dip switch to proper position: low amp for
a 30-amp service, or high amp for a 50-amp service.
See page 6 to help with the decision.
4. When supplying the new 4 wire service, connect line
2 to the terminal indicated by the dotted line in the
above diagram.
Additional wiring information:
GFCI PROTECTION: The new service must be protected with by a GFCI and a disconnect switch. The National Electrical
Code requires that spas connected to 240 volts circuits be equipped with a GFCI and disconnect switch. See National
Electric Code Articles 680-12 and 680-42. This spa is not equipped with a 240-volt GFCI or a disconnect switch. A GFCI
must be installed by a certified licensed electrician.
OUTDOOR LOAD CENTER: The addition of an outdoor load center such as a Siemens W0408ML 1125 or equal must be
added to the circuit. This type of load center provides both a GFCI and Disconnect Switch in a convenient configuration as
required by the National Electric Code. (See next page for suggested wiring configuration)
ISOLATED, DEDICATED 240 VOLT, 30 OR 50 AMP CIRCUITS ARE REQUIRED An isolated, dedicated 240-volt, 30 or 50 amp
circuit is required to provide the power necessary to properly operate the 240V equipment package.
PERMANENTLY HARD WIRED: All 240-volt operations wiring must be permanently hard wired, installed in grounded
conduit and installed in compliance with the National Electrical Code and all local codes. Do not use an extension cord.
Use of an extension cord will void the warranty.
WIRE SIZING MUST MEET ELECTRICAL CODES: All installations are different. Wire sizing must meet the National Electrical
Code and all local code specifications.
