Plumbing
Preliminary Assembly
Once your equipment pack is installed, attach the suction
equalizer tube assembly provided to the suction inlets of the
pumps. Align pump flange ends of the assembly and install
using gaskets, bolts and washers provided. Next, install the
1 1/2" x 3/4" reducing bushing and hose bibb provided onto
the tee on the equalizer tube. This hose bibb can be used
to drain the equipment pack, and if a garden hose is
attached between it and your water supply, it can help when
priming the pumps. Be sure there is an anti-siphon valve in
the water line to prevent fresh water contamination. Screw-
on anti-siphon valves are available for easy installation on
the house water spigot.
Install the two ells to the clear plastic pipes at the
discharge outlets of the pumps, orienting them in the
direction appropriate for your plumbing layout. Note that
each ell has a predrilled hole so you can install the two air
vent valves provided. These are necessary to bleed air
from the lines during priming. Install the air vents at this
time.

Interconnecting Piping
Plumbing lines between the equipment pack and the spa must not be longer than a total of 20 ft., including vertical
and horizontal dimensions.
Use 2" schedule 40 PVC pipe, with as few fittings as possible and bond with PVC solvent cement. When laying out
plumbing lines, avoid making configurations which might cause air entrapment in the system. Four 2" shut-off valves (not
provided) must be installed as close as possible to the equipment pack unit, below the spa water level, and accessible for
normal operation and maintenance. We recommend that they be ball-type valves. Do not use excessive amounts of cement
when bonding the valves to piping. Use pipe primer where required by local codes or when the air temperature during
installation is below 70 degrees F.
Install 2" check valves (swing type) supplied with the spa in the suction line to each pump. These aid in priming and
prevent reverse flow through the heater/filter pump when only the whirlpool pump is running. The arrow on the side of the
check valves must point in the direction of flow. If the base of the equipment pack is to be situated more than 20" higher
than the bottom of the spa shell, locate the check valves in the vertical part of the lines, near the pump.
