CONSTRUCTION
The tub surface is made of Lucite XL® Acrylic. The substructure 
is a composite laminate constructed of fire retardant fillers.
ELECTRICAL
Factory wired for 110 Volt 20 Amps. Ground-Fault Circuit 
Interrupter (GFCI) is required. The 20 Amp GFCI breaker must 
not supply any other circuits or devices. If Air is added to tub, 
electrical requirements is 110 Volt 30 Amps. An access panel 
must be installed to permit pump service.
The unit must be connected only to a supply circuit that is 
protected by a Ground-Fault Circut Interrupter (GFCI). Such a 
GFCI should be provided by the installer and should be tested on 
a routine basis.To test the GFCI push the test button. The GFCI 
should interrupt power. Push the reset button. The power should 
be restored. If the GFCI fails to operate in this manner, there is 
a ground current flowing indicating the possibility of an electrical 
shock. (See schematic on Pg. 5)
ELECTRICAL ROUGH-IN
WARNING: When using electrical products basic precautions 
should always be followed including the following: Rough-in 
wiring to equipment on a Ground-Fault Circuit Interrupter (GFCI). 
The GFCI circuit breaker must not supply any other devices 
or circuits. An access panel must be installed to permit pump 
service.
WARNING: Failure to follow instructions exposes users to risk of 
electrical shock or fire.
PLUMBING ROUGH-IN
The bath waste pipe protrudes below the base approximately one 
inch. Provide supply pipe, rough-in waste and vent per local code.
NOTE: On some models, the pump may exceed beyond the 
perimeter of the tub. If you have such a model, please make 
allowance during installation. See Page 4.
BATH WASTE AND OVERFLOW
Read instructions enclosed with bath waste drain for proper 
setting and fitting. Water tight installation of the drain is the 
installer’s responsibility. The waste and overflow is not included 
with the tubs unless purchased as an option. if not purchased 
with the tub, you must supply and install an alternative.
IT IS THE INSTALLERS RESPONSIBILITY TO
SUPPLY ACCESS TO PUMP AND EQUIPMENT.
1.  Once the tub is leveled, the tub must be supported or 
stabilized with plaster or mortar. If the tub has a supporting 
base, then mortar is not required.
2.  For Caulking, we recommend 100% sanitary silicone rather 
than latex.
3.  For quieter operation, you may choose to insulate the 
surrounding.
PROTECTION OF TUB
Use a section of the box, cut to size, and place in the bottom of 
the tub. When possible, keep the box cover over the tub. These 
steps will help protect the tub from abrasion or damage during 
installation.
IMPORTANT: If installing a skirt with removable panel, read in-
structions for the skirt prior to rough-in. The instructions are lo-
cated in the box with the skirt.
SETTING TUB IN PLACE
The tub needs to be set in mortar or plaster to level tub and pre-
vent shifting after installation. 
Apply mortar to the floor area that makes contact with the tub 
base. Set tub in opening and push on bottom of tub to secure in 
mortar. TUB MUST NOT “HANG” FROM LIP OF TUB! Do not 
allow tub lip and edges bear any weight of the tub. Do not fill tub 
with water until mortar has hardened. Seal all joints with sanitary 
silicone.
Alcove Installation
Set tub in place and level. Install leveling strips to the under side 
of tub lip Do not hang tub by leveling strips. Set tub in mortar and 
allow to dry.
FINISHING
Before finishing with your choice of material, make sure access 
entries are available to the pump, bath waste pipe, and plumbing 
fixtures. Finish as desired and seal around tub, preferably with 
sanitary silicone.
CLEAN PUMP SYSTEM
After tub is installed and ready to use, remove all construction 
debris and clean the pump and system.
SUGGESTION: During construction, we suggest that you cover 
tub to avoid use as trash receptacle.
TESTING
Connect trap to bath waste pipe. Temporarily connect garden 
hose for water testing. Tub must be clean before filling. Seal drain 
with plug and fill tub 2” above jet fittings. Run pump approximately 
20 minutes. Check for leaks. Turn pump off and let water sit in tub 
about 5 minutes. Check for leaks in return pipe and fittings. Drain 
the tub and shut off circuit breaker.
NOTE: ALL TUBS ARE FACTORY TESTED FOR PROPER 
WATERTIGHT OPERATION. However, the tub must be filled 
with water to check for leaks that may have resulted from 
handling, before finishing the tub installation. Universal Tubs is 
not responsible for any defects that could have been discovered, 
repaired or avoided by following this testing and inspection 
procedure.
