Installation Guide
– 4 –
For installations that are any combination of decks, walls, and pony walls, use the same methods to determine 
 critical heights. Remember that all supports must be at the same height and must establish a plane that is level 
 front to back and side to side. 
4. HOT WATER HEATER: As a rule of thumb, the capacity of the hot water heater needs to be at least 75% of the 
 capacity of the whirlpool tub. Formula = capacity x (2/3)
INSTALLING THE TUB
The installation of the tub/whirlpool tub must meet all applicable regulations and codes. Access must be provided for 
future service or removal of the pump, control boxes and wiring, without removing the tub or damaging the building 
structure or nish. An access panel at least 14" high by 16" wide must be located directly in front of the pump, control 
boxes or wiring. The optional Hydro Systems skirt with removable panel will satisfy this requirement. Minimum  
clearance in front of any panel should be 30" 
IMPORTANT - Never move or lift the tub by the pipes or other plumbing system components. 
Move or lift the tub by the deck or from under the bottom only.
1. READ ALL THE INSTRUCTIONS before you begin the installation.
2. INSPECT THE TUB before you begin the installation. Inspect the following:
•
 Is it the correct model? The corect size? The correct color?
•
 If options or upgrades were ordered, are they complete and correct?
•
 If the tub was ordered with components in non-standard locations, check to make sure they all are in their correct  
 locations.
• 
Check all components to make sure no damage occurred during shipping. 
• 
For Tubs with Tile Flange inspect for positive draft to bathing well
DO NOT INSTALL THE TUB if any of the above is not correct. 
Contact the dealer where the bathtub was purchased or call Hydro Systems directly at 661-775-0686.
You will need to know the bathtub serial number attached to your warranty card 
and also located on the back side of the bathtub when contacting Hydro Systems.
