SECTION 3 - INSTALLATION

Page S3-27

U. With the LX220

OFF

, restore the filter pump power and prepare to test the

PCS1 water flow as follows:

1. Someone should observe attic unit for any leaks during these tests.

2. Turn LX220 to

ON

[manual override] and observe attic for any leaks

from the plumbing.

3. Shut down immediately by turning off pump or LX220 to

OFF

if

any leak is present.

a. Fix any leak detected.

CAUTION:

Absolutely do not accept any small leaks in the plumbing!

Small

leaks only get worse. If you have allowed the silicone sealant and pvc cement
to cure a full 24 hours before using these joints in the attic, there should be no
leaks or problems in the plumbing joints!

V. Complete the remaining installation issues such as cleaning up, etc.

This is a

general attic process

to follow when a small access opening is

expanded. You, as the installer, are responsible for the safe application and
installation of the PCS1. Poor workmanship inside the attic can lead to a mess.
