PRODUCT INFORMATION Continued

The PHD holding drawer is intended to keep cooked food
warm and fresh. It is not intended for cooking or steaming
food. The product allows food to be cooked ahead of
incoming orders at peak periods and maintain freshness and
quality while the food is being serviced.

The humidity set point is intended to approximate a Relative
Humidity scale not replicate it. There are many factors that
limit the accuracy of an RH scale that can be achieved.
Settings will however be repeatable under consistent
circumstances and our humidity scale will be consistent with
all PHD products.

Air temperature and humidity settings will have to be
determined experimentally for optimal product life and
quality. As a guide we provide the following typical data:

PRODUCT

Hamburger Patties 70 158 60 minutes

Chicken Pieces 85 185 45 minutes

Chicken Chunks 85 185 45 minutes

Bread 60 140 60 minutes +

MAXIMUM

HOLDING TIME

NOTE: For Safe hot food holding, NEVER allow food
temperatures to be less than 140°F or 60° C.

For those foods that require additional moisture during the
holding period, water can be added to the interior pan. For
those foods that do not require additional moisture, the
bottom control and heating element can still be utilized
without the additional of water to the pan. It is suggested
that the drawer be closed during the heat up and holding
process to minimize heat loss, also to assure proper
temperature control.

It is suggested prior to holding prepared foods that the
drawer or drawers be preheated for approximately 60
minutes.

INTRODUCTION

Rating Plate

For proper operation, the information on the rating plate of
your new equipment must match your electrical supply.

When corresponding with the factory or your equipment
dealer regarding service problems or replacement parts,
be sure to refer to the particular unit by the correct model
number, including prex and sux letters and numbers and
serial number. The rating plate axed to the unit contains
this information.

Safety

It is the responsibility of the supervisor or equivalent
person to ensure that users of this equipment wear suitable
protective clothing and to draw attention to the fact that
some parts will by necessity, become very hot and will cause
burns if touched accidentally.

The PHD PLUS provides two heating zones. The upper
element rated at 350 Watts is the primary air heat source. The
lower element rated at 550 Watts is used to heat the water
when operating the humidity mode and assists in heating
the air in dry operating modes.

The temperature control provides the following features:

• Continuous actual air temperature display provides an
accurate indication for food safety.

• The temperature can be displayed in Celsius or
Fahrenheit degrees.

• Four Menu settings. Up to four preset air and humidity
setting can be made.

• A unique humidity program provides an accurate
and repeatable method of controlling the humidity
throughout the air temperature range.

• Air temperature settings up to 200°F/93°C.

• Humidity settings up to 90%.

Explanation of Controls:

°F DISPLAY LED: Indicates that the °F display is selected.

°C DISPLAY LED: Indicates that the °C display is selected.

PARAMETER ADJUST MODE LED: Indicates that the

parameter adjust mode is selected.

DIGITAL DISPLAY: Normally displays the actual air
temperature and pre-programmed menus. In set mode
displays other parameters.

SERVICE / SELECT KEY (Hidden on some models): Used to
enter the parameter adjust mode or select a preprogrammed
menu.

INCREASE KEY: Increases the selected parameter value.
Views the air temperature set point in operation mode.

DECREASE KEY: Decreases the selected parameter value.
Views the humidity set point in operation mode.

NOTE The display parameters may be changed in steps by
pushing the or keys repetitively, or automatically by
holding down the same key longer. Digits will increment
or decrement at accelerating rates as the or keys is
continually pressed.

Control Basics

There are a number of control features, which need to be
understood before proceeding with programming and
operating the PHD PLUS.

1. Default air temperature of 150°F or 66°C and 50%
humidity has been programmed in.

2. No preset temperature and humidity has been
programmed.

3. When the unit powers up the control defaults to the last
programmed setting.

Getting Started

Connect the power supply and turn the power switch to the
“1” position.

When power is rst applied to a factory unit: the display
will show [888] and the 3 status LED’s will come on for 10
seconds and then go o for 1 second.

The actual air temperature will be displayed.

Setting Air Temperature (default mode)

1. Press the Select Key until “Air” appears on the display.
Notice the LED is illuminated and will remain
illuminated until the set mode is exited. You will exit set
mode automatically when no key has been pressed for 5
seconds. The last value entered will be stored in memory.

Setting Humidity (default mode):

1. Press the Select Key until “HU” appears on the display.
Notice the LED is illuminated and will remain
illuminated until the set mode is exited. You will exit set
mode automatically when no key has been pressed for 5
seconds. The last value entered will be stored in memory.

2. Press the or key to increase or decrease the
displayed air temperature. The factory default is 150°F or
66°C.

NOTE: The temperature programmed here will become the
default setting. This setting will be restored even after the
power has been turned o.

2. Press the or key to increase or decrease the
displayed humidity setting. To activate the humidity the
setting must be greater than 10. To operate in dry mode
set the display to 10. The factory default is 50.

NOTE: The temperature programmed here will become the
default setting. This setting will be restored even after the
power has been turned o.

Selecting Menu Presets

When menu presets have been programmed they are then
available in operation mode. To select a preset, press the
select key momentarily. The rst preset “P_” will appear. Press
the Select key momentarily again to select another menu
preset or continue to press the Select key momentarily to

Reviewing Operating Setpoints

In operation mode, press the key to view the air
temperature set point. Press the key to view the humidity
set point

Alarm

If air temperature is < (less than the (Air setpoint – 10°C or
18°F) or > (greater than) the (Air setpoint + 10°C or 18°F), the
air temperature display will ash. Pressing any key will stop
the display from ashing.

Calculating the Water Temperature

To provide a simple and consistent means of setting the
chamber humidity we have created a relationship between
the water temperature and the air temperature where the
lower heat source is scaled in percent relative humidity.
By setting the humidity to minimum (10%), the lower
temperature will match the air temperature. In applications
where it is necessary to set the lower element temperature
less than the air temperature in dry mode or for a reference is
humidity mode we provide the preceding chart to calculate
the set point.
