RECOMMENDED PLUMBING

(continued):

Stand Pipe: A vertical pipe holding a column of water, topped with a column of air. The air pocket provides a "shock absorber"
effect, to reduce or eliminate the possibility of "water hammering" in the plumbing.
Strainer Removes particles from the water supply which could result in damage to plumbing components.

Pressure Reducing Valve: Required if the incoming water pressure exceeds 60 psi.

Check Valve: Eliminates the possibility of steam generafor water backing up into the water supply plumbing. (This check valve

may be required by local plumbing codes.)

WATER QUALITY REQUIREMENTS

If the purity of the incoming water is good, the generafor, the heating element and the valves should give years of trouble free. efficient
service with a minimum of servicing.

The recommended minimum water quality standards, whether untreated or pretreated, based upon 4 hours of operation before the steamer is
shut off and allowed to drain, are

as follows:

• TOTAL DISSOLVED

less than 60 parts per million

•SILICA

less than 13 parts per million

• TOTAL ALKALINITY

less than 20 parts per million

• pH FACFOR

greater than 7.5

Consult a local water treatment specialist for an on-the-premises water analysis and for recommendations concerning steam
generafor

feed

water treatment (if required), in order to remove or reduce harmful concentrations of minerals. The use of a

poor quality (highly mineralized) water will mean that more frequent servicing of water sensitive components will be
necessary. The fact that a water supply is potable is not proof enough that it will not be detrimental to the water sensitive
components. The steamer should be shut off for 3 minutes every 4 hours, in order to minimize scale build-up.

DRAIN

A 1" N.P.T. fitting is provided. The drain termination must be free venting. Up to two elbows and a maximum of six feet of I* I-
P.S. pipe may be attached to the termination. However, the piping must have a gravity flow and vent freely to the air. Each steamer
requires its own 1" I.RS. drain extension. Do not interconnect any other drains to this steamer's drain extension.

If these instructions

are

nor

complied with, there will be steam and water leakage past

the compartment door.

INSTALLATION CHECK

Installer must check out the steamer per the following procedure.

CHECK OUT STEPS

1) Empty the cooking chamber of all literature and

leave the door open.

2) Make sure the cold water supply line to the generafor is open.
3) Turn on the electrical service to the cooker at the fusible disconnect box.
4) Push the "water on" switch button to the right. The switch is illuminated when it is in the "ON" position.
5) Set the steam control at number ten. Steam should be visible inside the cooking chamber after five minutes of operation.
6) Let the steamer continue to operate for five additional minutes with the steam control set at ten. Steam flow should be visible for

this entire period of operation.

7) Set the steam control to number five. Steam will continue to flow but in a lesser amount.
8) To check the timer and buzzer, turn the timer past 10 minutes to wind it. Then reset the timer at three minutes. At the end of the
three minutes, the buzzer will sound for three seconds and then stop.

9) To completely shut down the steamer, push the "water on" switch button to the left (the light should go out), and turn the steam

control knob to zero. The steam generafor water will automatically drain out. At this time. the generafor flush cycle will be
energized. This system automatically flushes the generafor and drain line to assist in removal of lime deposits. After 3 minutes,
the flush cycle should end and the steamer should shut off completely.

If the cooker has functioned

as described, it is ready for use.
