3. Remove the cover on the top valve using an
adjustable wrench. Using a 5mm Allen key, place key
inside of the valve and turn counter clockwise slowly
until you reach a stop(see figure 2). Then screw the cap
back on the top of the valve and tighten to ensure a
proper seal(see figure 3).
4. Remove the cover on the bottom valve using an
adjustable wrench. Using a 5mm Allen key, place key
inside of the valve and turn counter clock wise slowly
until you reach a stop. Then, screw the cover back on
the top of the valve and tighten to ensure a proper
seal.
5. After steps 1-4, double check that all connections
are properly sealed using leak detection spray or
soap suds. If bubbles form, the system has a leak and
the screw connectors must be tightened again using
an open-ended wrench.(see page 17 for a
description of the leak test)

Ensure the screw connectors do not skew as you
tighten them. See below chart for proper torque.
Because the coupling works with tapping rings, it
may leak if you undo and reconnect the lines this will
void the warranty.
ATTENTION: Once you have made the connections
from the line set to the indoor head, ensure that the
black lines on the fittings are aligned. If they are not you
must re tighten them until they are aligned.
IMPORTANT: The conical ring on the valve has a
sealing function with the sealing seat in the caps. Take
precaution not to damage the cone, and keep it free of
dirt and other debris.
