General Cleaning And Inspection For Damage; Storage - Cardinal Health Alaris GW Technical & Service Manual

General cleaning and inspection for damage

To ensure that this pump remains in good operating condition, it is important to keep it clean and carry out the routine procedures
described below. All servicing should only be performed by a qualified service engineer, with reference to this manual.

Thoroughly clean external surfaces of the pump by wiping over with a lint-free cloth, lightly dampened with warm water and a
standard disinfectant/detergent solution.
Do not use the following disinfectant types:
- NaDcc (such as PRESEPT)
- Hypochlorites (such as CHLORASOL)
- Aldehydes (such as CIDEX)
- Cationic Surfactants (such as Benzalkonium Chloride)
- Iodine (such as Betadine)
- Concentrated Isopropyl alcohol based cleaners will degrade plastic parts.
Recommended cleaners are:
Brand Concentration
Hibiscrub 20% (v/v)
Virkon 1% (w/v)

 Labels should be flat and legible. Any label, if no longer fully adhered, must be replaced if it represents a path for fluid ingress.

Case components must be checked for damage that may affect function, fluid ingress route or present a user hazard and be re-
placed if necessary.
 Check the pole clamp screws are not loose and that the threads are not damaged. Check that it folds away and ensure arm is not
bent.
 Inspect the AC power supply plug and cable for damage.

Storage

If the pump is to be stored for an extended period it should be cleaned and the internal battery fully charged. Store in a clean, dry
atmosphere at room temperature and, if available, employ the original packaging for protection.
Once every 3 months during storage, carry out functional tests as described in this chapter and ensure that the internal battery is fully
charged.
