For PD2K installations: Follow the steps below.
For PD1K installations: For the first expansion
kit, connect the air supply tube (35) directly to the
electrical control box (Z). For the second through
fourth expansion kits, follow steps 2–4 below.

NOTE:
NOTE:
NOTE: A 6 ft (1.83 m) length of 1/4 in. (6 mm) OD
polyethylene tubing (35) is supplied with the kit to
supply air to the expansion pump’s solenoid manifold
(3).
1.
See the PD2K Repair-Parts Manual. Remove the
PD2K fluid panel cover to expose the air supply
tubing to the two existing solenoid manifolds.
2.
Cut the air supply tubing upstream of the Y-fitting.
3.
Install the Y-fitting (36) supplied in the kit as
shown, to restore the air supply to the two
existing solenoid manifolds.
4.
Connect the supplied 1/4 in. (6 mm) OD tubing
(35) between the open branch of the Y-fitting
(36) and the air inlet of the solenoid manifold (3).
This supplies air to the expansion pump solenoid
manifold, as shown in the detail of the illustration.
NOTE:
NOTE:
NOTE: If you are installing a fourth pump, make
a second splice in the main solenoid air supply
line and plumb as explained above.
