NOTE: That both transfer caps only mount in one orientation. Prior to installation of cap assembly be sure to check that the
stainless steel spring and the plastic spring support is in place attached to the inside of the cap assembly. Next you can
wipe the outside edge of the O-ring on the cap and the inside mating area of the valve with a clean cloth & re-apply a thin
layer of silicone lubricant like Dow #7.
BE SURE NOT TO USE ANYTHING HYDROCARBON BASED SUCH
AS VASELINE OR PETROLEUM JELLY TO LUBRICATE PLASTIC
COMPONENTS OR O-RINGS AS THEY WILL BE DAMAGED BY
THE HYDROCARBONS AND POTENTIALLY CAUSE FAILURES
THAT CAN RESULT WITH LEAKS.
Noting the one possible orientation of the transfer drive cap, use one hand to press in and support the transfer drive cap while using the
opposing hand to start two screws in, one on the top and one opposing it on the bottom. Tighten the screws in evenly so the cap seats
the O-ring without getting pinched or damaged. Screws should only be hand tightened with a 5/32” or 4mm allen wrench, DO NOT OVER
TIGHTEN SCREWS.
Be careful and make sure the meter cable doesn’t get under the drive cap
while tightening as it will result in damaging the cable.
Position the large white drive gear with the “A” pointing toward the 1
o’clock position and then press it onto the stainless steel drive shaft, make
sure it snaps & locks into position.
The white drive gear is splined to the drive shaft and will only assemble in
one orientation. Because of this it is not necessary that the discs and gear
be exactly positioned, the positioning needs to be approximate but they
have to fit on the shaft.
Next install the larger black reducing gear onto the stainless steel shaft,
then install the remaining smaller reducing gears from left to right. Re-install
the grey reducing gear cover over the gears and affix with the 3 stainless
steel screws. Now you can re-install the drive motor by pressing the spring
clip loop to the right then rotate the motor as you are inserting it so the
gear of the motor meshes properly with the reducing gears. Release the
spring clip loop and rotate the motor untill the motor housing engages with
the plastic nub inside the housing that holds the motor in place and make
sure that the top of the motor is flush with the top of the grey gear housing.
Press the drive motor wires down into the strain relief of the drive cap, now
you can re-install the cover assembly.
NOTE: After completing any valve maintenance involving the valve drive assembly or the transfer drive assembly please press
and hold the NEXT & the REGEN buttons simultaneously for 3 to 5 seconds to perform a soft reset which will synchronize
the control valves positions.
