2.O3 Mechanical Installation
Installing the Rinse Injection Fitting
1) Install the rinse injection fitting to conform to local plumbing codes.
2) The injection fitting is designed to fit global needs. It should thread
directly into a 1/8” NPT (North America) or a BSP (Global) female
threaded connection. As an alternative to the threaded connection a
barb fitting adapter is also included.
3) If the machine’s rinse plumbing is thin-wall pipe, use a saddle clamp
with the 1/8” threaded hole.
4) If the machine already has a tapped hole to accommodate the fitting,
skip to Step 8
5) Choose a location for the rinse injection fitting that is downstream from
the vacuum breaker and at the proper height per local plumbing codes.
This point is either into the pressurized rinse line or upstream of the
booster heater for the rinse water..
6) To create the threaded connection at your selected location, drill a
9mm (11/32”) hole in the rinse plumbing at the injection location.
7) Tap the hole drilled in step 6 with a 1/8” tap (NPT or BSP depending on
the region)
8) Install the injection fitting. Use thread sealant to ensure a leak-free
assembly.
Installing the Detergent Injection Fitting
1) When choosing a mounting locating, make sure that the detergent
infection fitting will be:
•
Above the water level of the filled wash tank.
•
Discharging detergent directly into the wash tank and not on top of
any shelf areas or other obstacles that could prevent detergent from
falling directly into the wash tank.
2. Previously punched holes may be suitable but always confirm that the
fitting is correctly placed. 10mm (3/8’’) holes are common in Europe
and 22mm (7/8’’) holes are common in North America. If an appropriate
hole is present, go to step 4.
3. If a hole is not available already, drill a 10mm (3/8’’) hole at the center of
your chosen detergent injection location on the dish machine tank.
4. Remove the retaining nut from the supplied detergent injection fitting
and gather the gaskets and washers supplied with the unit.
5 a. For a 10mm (3/8’’) hole insert the detergent injection fitting, with a
rubber gasket, into the hole you drilled earlier.
b. For a 22mm (7/8’’) hole insert the detergent injection fitting, with a
large rubber gasket backed by a large stainless steel washer.
6. From the inside of the machine install a second rubber washer,
stainless backing washer if using a 22mm (7/8’’) hole, and the retaining
nut. Tighten finger-tight, then snug using a wrench.
