SPECIAL
APPLICATIONS
AND TIPS
PARKING LOT ISLANDS:
If islands are small, consider tying several of them together on the same zone.
• Once you have determined that the conditions of the islands are similar enough to interconnect them,
design each for the same precipitation rate by using the same Techline CV and spacing.
• Use one Low Volume Control Zone kit at the source, and install a TLSOV or TLFIG8 either at the end
of the last island or, if the islands dead-end, on each island.
• Connections between the islands should be PVC, or as called out by the designer or local codes.
ELECTRICAL GROUNDING:
• The effectiveness of electrical grounding is dependent on the soil and its moisture content. In moist
soil, grounding is more effective than in dry soil.
• One method of ensuring moist soil is to install a length of Techline CV along a length of unclad
copper wire being used for grounding purposes. The Techline CV is installed in the usual method.
Run it from a separate station on the controller to give you maximum control.
• Techline CV can also be installed over the top of a grounding plate or ground rod.
TECHLINE CV ABOVE AND BELOW GRADE:
Techline CV is designed to be used in a variety of ways:
• It can be laid on the surface, (it’s UV resistant!) and held in place with Techline Staples (TLS6),
• It can be laid on the surface, stapled into place and covered with mulch, or
• It can be buried below grade.
NOTE: When using Techline CV above grade with staples, use enough staples to firmly hold the tubing
in place, especially in freezing climates.
