16.1 Maintenance
Routine user maintenance should include a regular inspection of the tubing assembly for excessive wear
and leaks. Many service problems can often be cured by simply replacing a worn tubing assembly. To
insure high accuracy, the pump rotor and tubing clamping mechanics of the pumphead should be kept as
clean as possible at all times.
The unit cabinetry has been designed to an IP31 rating. The plastic top is mineral filled polypropylene and
the base is painted cast aluminum. The pumphead and outer cabinet may be wiped down with warm
water and any mild household cleaning solution. Never use abrasive cleaners or strong acids as cleaning
solutions. Never place liquid containers on top of the OmniSpense
®
ELITE as a spill could result in liquid
entering the dispenser. If liquid should accidentally contact the front panel, the unit should be
disconnected from the AC power source immediately and carefully dried with towels and warm air.
Although the OmniSpense
®
ELITE is designed for easy service, it is highly recommended that the
instrument be returned to Wheaton Industries should any major repairs be needed.
Pump rollers can be occasionally lubricated with Teflon lubricating oil.
