Post –Installation LCD-8 Test
Most problems result from installation errors. Before testing, verify that unit is prop-
erly installed.
1. Connect power to snow melting system. Wait 15 seconds; system should
not actuate.
2. Using ice water or other cooling agent, cool ambient air temperature sensor
to below 38°F (3.3ºC); system should not actuate. Apply moisture to moisture
sensing grid. System should actuate in less than 15 seconds.
3. Dry moisture sensing grid. Disconnect power to snow melting system. Wait 1
minute, then reconnect power. If system actuates, ensure sensing grid is dry
and ambient air temperature is above 38°F (3.3°C), then repeat this step.
