Installation Notes
Install this product according to the installation guide.
Cast iron whirlpools are extremely heavy, making some
drop-in installations difficult. Splitting the deck/surround is
recommended if installing into a deck.
Floor support under whirlpool must provide for a minimum of
62 lbs/square foot (301 kg/square meter) loading.
Fixture conforms to ASME A112.19.1/CSA B45.2. All
