I mounted and wired the Intellistart module into the compressor circuit. I dressed loose wires and dated the module, 05/24/19. I tested the unit for proper operation. Customer paid balance of the repair.

Wired in pumps. While Bob was insulating pipes I cleaned evap coil and replaced contactor. Pressurized Loop to 40psi and Returned power to system and ran ac. Checked operation. When flushing out loop we found water to be very brown. Took water sample to send away to check levels. Office please follow up with customer.

On arrival set both thermostats to call for cooling. Measured return temperature, supply temperature, amps, and voltage. Inspected electrical connections, contactor, replaced filter for unit #1,cleaned condensate drain lines and condensate drain pans. Measured voltage absorption system rated 40mfd. Actual reading 42.5mfd. I explained to the customer the benefits of installing 2 ez traps for both units and also recommended to get their ducts clean. Units are operating normal at this time.
