Comments Note -
There are two methods of producing the needed pressure in steps 11 and 15,
using the pumps "Motor" or
separa
te "Hand pump".
Connect a hand pump only if it will be used to crea
te pressure in steps 11 and 15,
and verify
Z-Class pump user adjustable relief valve is set higher than maximum pressure used is step 15. Boot sequence xxxx psi is the current pressure value of SET PRES psi is the current unit of pressure measurement First step into the hidden calibra
