1. Pipe connections: The unit is equipped with field connection from either top or bottom of the unit. Unit connections shall be made internal to the unit.

2. Pipe adapters: The unit shall include 1-in Rotolock to sweat adapters and associated Teflon seals.

Q.FLOW METER

1. Flow meter shall be factory piped inside the unit and connected to microprocessor controls to provide water flow rate through the unit. The microprocessor controller shall also use this information to provide total unit capacity out of the unit while in operation.

2. Flow meter shall be stainless steel construction turbine type meter, compatible with glycol/ water solutions up to 50%, with accuracy of 1.5% or better on range 5-50 GPM.

R.CABLE WATER DETECTOR (OPTIONAL)
