Air Vent Connection; Liquid Soap Connection - Maytag MFS18PDFTS Installation And Maintenance Manual

4.9. AIR VENT CONNECTION

WARNING!
!
VAPOURS ESCAPE FROM THE MACHINE THROUGH THE AIR VENT OPENING!
DO NOT COVER OR CONNECT TO ANYTHING!
On the backside, the washers are provided with an air vent opening of O.D. 75 mm / 3".
It is part of the back flow prevention water system. It also takes care that the tub can not be pressurized by water
intake and vapor of the hot water. It allows also proper measuring of the water level.
For the safety of everyone make sure that unauthorized persons cannot reach the backside of the machine.

4.10. LIQUID SOAP CONNECTION

General : Always use liquid soap pumps with a flow rate that can bring the requested quantity in less
than 30sec.
Important : Start pumping immediately after the water valves are open. The incoming water dilutes the liquid
soap and brings it into the tub assembly.
Caution : Secure the location of the wiring and hoses in such a way that they can not be pinched, damaged
or rubbed.
For all models except model „MFSxxPNF"
The washer has provisions for connecting external dosing of liquid soaps. For connecting the liquid soap inlets
and wiring the top panel needs to be opened.
On the rear panel is a plastic
that will be used, drill holes (max. 5) of Ø 0.315" / 8 mm in the connection part for each pump. Also drill holes
(max. 5) of Ø 0.256" / 6.5 mm in the soap dispenser nipples located at the back of the soap
fig.4.10.B., pos.1. By default, these nipples are closed. Drill only the ones that will be used. Take care that the
drill particles are carefully removed so that they can not clog up the hoses and openings.
Between the two parts, connect a PVC hose with a somewhat smaller diameter then the 0.39" / 10 mm nipples,
so that the hoses have tension on the nipples. Secure liquid hoses by means of clamps on both sides. Take care
that the hoses are as straight as possible in a direct line and secure the hoses in such a way that they can
not be damaged or rubbed.
