Connecting the System
•
All tubing cuts must be even and clean�
•
Most fi ttings are a push-to-connect design� Use a twisting motion when pushing tubing into
the fi ttings to ensure ends are fully inserted through the collet and into the internal "O" ring�
•
Several fi ttings are a hose barb design� The 1/8" metal barbs are extremely strong and tight when the tubing is
pushed on� If you must remove the tubing for any reason, make a cut along the edge of the tubing at the barb
then remove, make a fresh cut and reinstall�
•
The remaining barb connections are thermoplastic, and the tubing should be held in place suffi ciently by being
stretched over the barbs since there is no pressure in the lines� However, if you feel the tubing could be pulled
during normal use, you may wish to install a stainless hose clamp to hold the tubing fi rmly in place�
•
Do NOT use Vaseline or other lubricants (other than clean water) on the tubing� Moisten the tubing ends with
water before inserting tubing into push-to-connect fi ttings if lubrication is needed�
•
Cut the tubing to a suffi cient length so that no tubing line is tight or stressed, and so the VistaCool tank
assembly can be moved within the cabinet easily�
•
Tubing connecting to the drain (both the condensate lines and coolant line) should be as short as possible and
must not droop, loop or sag in a way that would form a trap that could cause fl ow restriction or backpressure�
•
Ensure that fl uid fl ow is not impeded by kinked or bent tubes�
•
Manually FILL THE TANK before starting the system� See below�
1� Fill the water tank COMPLETELY� Remove the manifold and coil assembly from the tank
1
by twisting the manifold counter clockwise� Fill the tank with COLD water, replace the
coil manifold into the open hole and place the tank into position under the sink�
