1 Hydroixer motorized temperature mixing unit 67 series CCREDITED CLEI 09/ N ISO ISO 900 No. 000 unction The 67 series Hydroixer provides a modulating three-point floating type non-spring return motorized three-way mixing valve to regulate the fluid temperature in heating and air conditioning systems in response to a separately-sourced outdoor reset controller. It comes complete with onboard three-speed or variable-speed pump, motorized three-way mixing valve, check valve, supply and return temperature gauges, secondary circuit shut-off ball valves and pre-formed insulation shell. Versions are available with either the three-speed Grundfos UPS -8 pump or the variable-speed lpha -U pump. The unit can be ordered with supply flow and pump on the right or left side. The adjustable differential pressure by-pass valve, code 9600 and wall bracket code 60 are optional. The unit comes with male union connections which require separately purchased, inch sweat or NPT, top outlet and bottom inlet fitting kits.

4 Wall bracket racket installation The mounting bracket for wall placement must be attached with dowels, using the special holes in the base. The Hydroixer 67 series unit is applied to the bracket using the slots under the hex part of the shut-off ball valves. 60 Wall mounting bracket for 67 series units. Stainless steel. Hydraulic characteristic of code 9006 Differential pressure by-pass valve p (kpa) (psi) Calibration positions (l/s) Hydraulic characteristics shown account for the presence of ball valves Installation of adjustable differential pressure by-pass valve 0 (gpm) djustable differential pressure by-pass valve 9006 The adjustable differential pressure by-pass valve ensures the head pressure of the pump is proportional to the number of two-way on/off, modulating or thermostatic valves being closed in the secondary circuit, preventing pump overheating and excessive fluid velocity.
