Chapter 4: Preventive Maintenance
Prepare for Storage or Shipment
Before the washer is shipped or stored, it should be rinsed and soaked with
disinfectant and then purged of all fluid. Perform these steps when leaving the washer
unused for a long period of time.
Long_Shutdown
The recommended onboard Maintenance program is LONG_SHUTDOWN . This
program flushes and soaks the supply tubing and manifold with disinfectant, then
flushes the system with rinse, and finally purges the system of fluid.
For the ELx405™ HT2/HTV2: Before switching from one manifold to
another (e.g., before removing the 192-tube manifold and installing
the 96-tube manifold), Bio-Tek recommends that you perform this
procedure to thoroughly clean whichever manifold will be removed and
stored.
The LONG_SHUTDOWN Maintenance program primes and soaks the washer with
the Prime Volumes and Soak Durations specified in the P_DECON1 and P_DECON2
Prime programs. These prime programs can be edited for optimum cleaning.
Refer to the charts in the
Prime Programs section of this chapter for a list of
default Prime program parameters and to
Chapter 3
,
Operation
, for instructions
on editing these parameters.
Three supply bottles are required for this procedure: one for
disinfectant, one for rinse, and one for air.
Caution! Be sure to check the percent NaClO of the bleach
you are using; this information is printed on the side of the
bottle. Commercial bleach is typically 10% NaClO; if this is the
case, prepare a 1:20 dilution. Household bleach is typically 5%
NaClO; if this is the case, prepare a 1:10 dilution.
1. Turn off the instrument. Empty the waste bottle.
2. Prepare an aqueous solution of 0.5% sodium hypochlorite (NaClO, or
bleach).
3. Fill one supply bottle with at least 400 ml of bleach solution (disinfectant).
4. Fill another supply bottle with at least 800 ml of deionized water (rinse).
5. Keep the third supply bottle empty (air).
