Installation Sheet

•
It is not recommended that the blower be mounted over 8 feet away from the tub. The supplied wiring
between the tub and the blower is approximately 10 feet long.
•
Remote blower locations – There are several locations where the blower can be located. There must be a GFCI
electrical outlet within 2 feet of the blower. The blower is approximately 9.25 inches long and 8 inches in diameter
and 5” high. Substantial ventilation is required to keep the blower from overheating and to supply the large volume
of air being sent to the tub. Never wrap insulation around the blower as this will cause the equipment to fail. The
best location is directly below the tub in the floor joists. This location keeps the distance short and offers easy access
from below. If the room below has a finished ceiling, there are many fixtures such as HVAC return that can be used to
camouflage the access panel in the ceiling. Other possible locations include an adjacent closet, vanity or a same
level attic. Every home is different and there may be other desirable locations. Keep in mind that the blower must be
accessible for any future servicing.
•
Remote Blower Kit – If the blower is not mounted directly adjacent to the tub, a remote blower kit will be required.
The kit consists of: extension pipe, couplings and cable. Please indicate the necessary length of pipe and cable re
quired.

FIXTURES
•
No Fixtures can be mounted on the tub deck. Floor and wall-mounted fixtures are required.
•
Wall-Mounted – The position of the tub and the reach of the spout are critical. Pay special attention to the spout
reach when choosing your fixtures. Be careful to ensure the spout will extend out far enough to clear the tub deck
and the falling water will not hit too high up the side wall of the tub and splash.
•
Floor-Mounted – Some freestanding fixtures must be anchored to the tub drain for stabilization.
INSTALLATION INSTRUCTIONS FOR SOAKING WITHOUT PEDESTAL
Note: This is a sub floor drain. Access from below tub is recommended for installation. If there is no access from
below, the installation is more difficult. Clearance for the drain will be required and the
floor near the overflow will
need to be completed after the drain is installed. See picture below.
Drain kit parts breakout is shown in illustration to the right.
Hydro Systems recommends using clear 100% silicone sealant, DO NOT use plumber’s putty.
1) Place the tub in the exact position of final installation. The bathtub cannot be repositioned once it is
plumbed and installed. The tub is designed to sit on top of the finished floor, however, you may need to
leave an area by the drain open until installation of the drain is complete.
2) Ensure location is structurally sound, flat and level.
3) Elevate the tub to allow access to the bottom of the tub from the drain to the overflow area. The tub is
very heavy; use appropriate supports.
4) Temporarily “dry fit” the drain kit and trim the pipes to proper length. Note the distance from the edge of
the tub to the center of the overflow pipe. This measurement will be used to verify the location of the hole
in the floor for the overflow pipe. Also see rough-in dimensions on previous page.
5) Remove the drain kit from the tub.
6) Use emery cloth, grinder or wire brush to remove the plated finish from the pipe where it will be soldered
to the ‘tee’.
7) Provide opening in floor below drain of approximately 6” x 6”. This will be completely covered by the tub.
8) Install tub in precise location desired. Use only 100% clear silicone to adhere tub to floor.
9) Using the distance noted in step #4, drill hole in floor for overflow pipe.
10) Re-assemble drain kit on tub using clear silicone under drain strainer. Remove excess silicone immediately.
Tighten waste flange assembly and ferrule until seated plus 1/4 turn. Remember to install bell flange on overflow
pipe. Slide the bell flange high up on the overflow pipe to avoid heat damage during the next step.
11) Carefully solder connections at brass ‘tee’. Wrap a wet rag around overflow pipe to prevent the heat from
damaging the plating. Always use proper heat shielding to protect the surrounding materials.
