SYSTEM DESIGN
PARALEVEL LAYOUT AND DESIGN CRITERIA
START UP
The Paralevel is designed to control the water level in a swimming pool or spa. The “Posi-Click” control makes
adjusting the water level very easy. Four clicks (or one revolution) of the adjustment wheel changes the water
level by ¼”. The Paralevel uses “Smart Sensing”, eliminating rapid cycling of the device even when the pool is
being used. The user can use 1 ½” or 2” pipe for the balance line. The water line can be plumbed with ½” or
¾” pipe. The Paralevel can also be plumbed with 2” pipe for overflow protection, offering the highest overflow
protection in the industry.
1. Paralevel should be level and plumb.
2. The Paralevel main housing is engraved with “Max
High; Max Low; and Pool Level”. The housing
should be mounted so that the “Pool Level”
line is at the expected water level.
3. Maximum water pressure is 80 psi.
4. The fill rate at 50 psi is 120 gph (2880 gallons per
day).
5. Warning: Balance line and overflow line must be
plumbed straight. Failure to keep the run of pipe
straight may cause an airlock.
