“TecMark” Switch:
1) TecMark switches do not have an
adjustment wheel lock. See Figure 23.
2) With water pump operating and electrical
power supplied to the heat pump, slowly
rotate top of adjustment wheel to the left
or right until “FLO” code (just)
disappears.
3) With electrical power remaining “ON” to
heat pump and heat pump operating,
shut off power to circulating pump. If
switch has been correctly adjusted, when
water pump stops, heat pump will shut
off and “FLO” code will display.
4) Reinstall heat pump front cover.
4.3.g Water Hammer Suppression
AquaCal AutoPilot strongly recommends a water hammer suppression standpipe be installed whenever a
cyclic cleaning system (in-floor cleaning system) is installed. This will prevent possible water hammer
damage to equipment.
Rapidly closing valves can cause a wave of non-compressible water to flow backwards in the piping
system, damaging equipment as the water stops abruptly in the system. Damage to water circuits caused
by water hammer effects are not covered by warranty.
