For absolute safety always wire through the pump pressure switch. This is a WATER PUMP controller: It will not work with air in the system.
ALWAYS prime your system before starting work. Do not set the Cal value too high. Setting it higher than necessary places extra strain on both the pump and the controller in a dead end situation.
This can result in damage to both the pumps and your controller. Please see or other items. We supply many window cleaning supplies including a full water fed pole set up, van's, water tanks and resin.
