9. Air Inlet Valve Timing
• (First check lever pivot wear per #6 above)
• Call the QED Service Department for correct air valve timing for your pump.
Returning Equipment for Service
If the equipment needs to be returned to QED for servicing, please follow these steps:
1. Call the QED Service Department and obtain a Return Material Authorization (RMA) number. Please have available
the contact person's name, company name and address, phone number, fax number, reason for the return, and the
names of the chemicals to which the equipment has been exposed.
2. Clean all equipment before shipping. (See Equipment Cleaning Requirements at the end of this section). If the
equipment must be cleaned after it arrives at QED, the customer will be charged for the cleaning and disposal of
material, if necessary. (Cost can be $500.00 per piece of equipment cleaned.) It is also important to note that shipping
equipment with a known hazardous waste is a violation of federal law. Drain and dry all equipment after cleaning.
3. Package the equipment so that it will not be damaged in shipment. Use bubble pack rather than Styrofoam flakes as
packing material.
4. Ship the equipment via a carrier and service level (i.e., one-day, two-day shipping) in consideration of probable service
time and return shipment time.
5. It is recommended that such shipments be insured so, if the shipment is badly damaged or lost, the customer can
replace the equipment at little or no cost.
6. Include the contact's name, company, phone number and RMA number given by QED.
7. Write the RMA number on the outside of the packaging so it will be directed immediately to the QED Service
Department.
Equipment Cleaning Requirements
If the equipment is to be shipped to another site or to the factory for service, it needs to be thoroughly cleaned before
leaving the site. Cleaning the equipment protects the user (sender), the shipper, and the receiver from dirt and/or
contaminants. If the equipment is not cleaned prior to shipping for servicing, it may be severely delayed, refused or the
shipper may be charged a cleaning fee. Before packing and shipping, ensure that the equipment is dry inside and out.
To Clean the AP Ultra:
1. Pump clean water or water with a gentle soap solution (e.g. Dish Soap) through the pump to remove free product and
particles.
2. Rinse all soap off of the equipment.
3. Soak and rinse the outside of the unit with water to remove loose debris and dirt.
4. Pressure wash inside and out to remove difficult dirt and contaminants.
Caution: Use low pressure (less than 40 psi (2.76 bar)) when pressure washing.
