example if a set point of 140 °F is desired and the
temperature reading is 155 °F, you must turn the
low flow adjustment counter-clockwise to lower
the set point temperature from 155 °F down to
140 °F.
(IMPORTANT - When making the low flow
adjustment the high flow adjustment shaft
SHOULD rotate with the low flow adjustment.
If it does not do so, you will have to turn it by
hand while making the low flow adjustment).
Allow the unit to stabilize to be sure that the unit
will remain at the desired set point. The low flow
is now adjusted and should not be readjusted.
10. To make the high flow adjustment, SLOWLY
increase the flow of water through the unit to
drain while monitoring the outlet thermometer.
When the outlet temperature has dropped by
approximately 10 °F below set point for a
Model 415E, make your high flow adjustment
while maintaining that flow.
11. Place a small screw driver or center punch
through the hole in the high flow adjustment stem
(see Fig. 7-1) and turn it in a clockwise direction.
This will start to close the valve restricting the
cooling water and cause the outlet water
temperature of the unit to rise. Continue until the
outlet temperature is back up to your required set
point.
(IMPORTANT - When making the high flow
adjustment the low flow adjustment SHOULD
NOT rotate with the high flow adjustment. If it
does, you will have to hold it stationary while
making your high flow adjustment).
12. The unit is now adjusted.
(IMPORTANT - If for any reason you must
readjust the unit, you will first have to return
the high flow adjustment back to its full up
position as stated in point # 7).

START-UP AND ADJUSTING PROCEDURE
FOR MODEL 535EP, 665SEP and 8120
Top Of Mixing Valve
Fig. 7-1
Follow all the steps 1-6 as stated in the adjustment
procedures of the model 415.
7.
Locate the low flow temperature adjustment
(LFT) and the high flow temperature adjustment
(HFT) on top of the mixing valve hidden under
the hex bonnet (See Fig. 7-1). Before beginning
adjustments, check to make sure the LFT is
fully closed. To do this, turn the LFT clockwise
until it stops. Also make sure the HFT is fully
open. To do this start by pressing down on the
HFT when water pressure is present on the unit
and there is no water flow through the unit. The
HFT should only depress about 1/8". If it pushes
in further, turn the HFT stem counter clockwise
to open. Check every turn until there is only 1/
8" travel to the HFT when pushed down (Note:
with water pressure on the unit the stem should
pop back up after depressing it). If the HFT
stem will not depress at all the valve is opened
too far and you must turn the adjustment
clockwise until there is 1/8" travel downward to
the stem.
