2 THEORY OF OPERATION
The CoolDrawer is a refrigerated drawer with a wide operating temperature range of between +15 and
–25
O
C, (59 and -13OF) having five different operation modes of a freezer, chiller, fridge, pantry and even to a
wine cooler. The system has a horizontally mounted evaporator in the floor of the cabinet, where the cold air
is drawn through the evaporator by the evaporator fan, and then passes into the ducted back wall to enter
the cabinet higher up.
It has a fan forced condenser system utilizing the benefits of electronic temperature control and has a
variable speed compressor (VCC).
For service access into the CoolDrawer, refer to the servicing procedures (Section
12).
Removal of the complete drawer is carried out by the removal of the side trims (refer to Sections
3.12 and
3.13).
Access to the main power controller is gained by the removal of the lower front panel.

Instructions supplied with it.
The CoolDrawer MUST be installed to allow for future removal from the enclosure if service is required. Do
not seal this CoolDrawer into the cabinetry with silicone or glue. Doing so will make future servicing difficult.
Fisher & Paykel will not be liable for any costs associated with removing or replacing a sealed-in product, nor for
repairing any damage that may be incurred by doing this.
Care should be taken when the appliance is installed or removed to reduce the likelihood of damage to the
power supply cord.
Failure to install the CoolDrawer correctly will invalidate any warranty or liability claims.
If the power supply cord is damaged, it must be replaced. Parts are available from an Authorised Fisher &
Paykel dealer.
Cabinetry must be sufficiently robust to support a combined product and food load of 100 kg (220 lb). Bearers
may be required to support the internal shelf.
Before installing the CoolDrawer, please make sure that:
The switched power outlet must be outside the refrigerator drawer cavity so that it is accessible after
installation.
The switched power outlet must be located outside the cavity, within 1400mm (55") from the CoolDrawer
cavity if situated on the left-hand side of the cavity and within 840mm (33") if situated on the right-hand side of
the cavity.

3.4.1 Integrated Panel Material
• 16 – 20mm (
5

• Adequately sealed to withstand moisture (50
O
C/122OF @ 80% RH).
3.4.2 Height Of Drawer Panel
The following information is required to correctly define your Drawer panel height:
Dimension Data Source
A Reveal dimension Your kitchen designer
B Height between top of internal shelf and underside of benchtop Your kitchen designer
C Bottom face of Drawer panel to top of internal shelf Min. 152mm (6”)
Max. 184mm (7
1
/4”)
D Drawer panel height Calculated from A, B & C
To calculate D complete the following equation:
D = B - A - C
Example: B = 686mm (27”)
A = 20mm (
13
/16”)
C = 184mm (7
1
/4”)
Therefore D = 686mm – 20mm – 184mm = 482mm (27” -
13
/16” - 71/4” = 1815/16”)
3.4.3 Height Of False Panel
Determine the height of the false panel according to the individual kitchen cabinetry requirements,
maintaining a 4mm (
3

4 USING ALTERNATE ENERGY GENERATION
One of the big benefits of the Inverter drive motor technology found in CoolDrawer is that the motor is very
efficient in its energy usage. If running a CoolDrawer from alternate energy sources is being considered, the
following is a brief collection of facts and field observations to assist in making any decisions.
4.1 Product Facts
Average Power Usage.
When used in freezer mode 330kwh/year.
Peak Power Usage.
Peak power is controlled to less than 200W.
Motor Starting Surge.
The CoolDrawer brushless DC motor is electronically controlled. One of the big benefits of this type of
technology is that there is no power or current surge when the motor starts. Power is ramped up
progressively via the electronics.
Operating Voltage.
The CoolDrawer is guaranteed to operate on an AC sinusoidal voltage source of 230V rms +/- 15% at 50Hz
+/- 5%.
4.2 Using A Battery Driven Inverter Supply
There are many different brands and models of inverters available in the market today and often their output
voltage waveform is modified or non-sinusoidal. We sent an enquiry to an inverter manufacturer about
whether an inverter output had to comply with any regulatory standards or guidelines. The reply read:
”There are no guidelines that modified sine wave inverters are required to follow as pertains to the
amplitude, quality or shape of the output waveform. The only regulatory guidelines we choose to follow are
safety guidelines.”
As such we cannot guarantee the operation of a CoolDrawer running from an inverter supply if it does not
comply with our Operating Voltage requirements listed above.
Are there existing customers who are successfully running a CoolDrawer from an inverter supply? - Yes!
There are many installations where these types of refrigerators are successfully operating on an inverter
supply. In our experience, if an inverter meets the following technical criteria, then operation and reliability
should not be an issue:
• RMS Voltage: 230V +/- 15%
• Frequency: 50 Hz +/- 5%
• Peak Voltage: 400V peak
Some inverters have an rms voltage inside specification, but do so by having short duration high voltage
pulses. Some of these voltage pulses can be above 400V, which is higher than the rating of the controls. If
the controls are continuously exposed to these high voltages, it may lead to premature failure of the
electronics and/or the Inverter electronics.
Power Rating.
• 1kVA (1,000VA) minimum.
While the CoolDrawer only requires 200W peak power, the VA requirement is higher. Successful
installations have a rating of 1kVA min.
Some brands of inverters have an “Idle/Sleep” mode. (This puts the inverter in to idle/sleep mode when no
load is being applied). As the CoolDrawer uses less than 2 watts in the off cycle, these type of inverters
need to have the inverter “idle mode” turned off or disabled, as the electronics in the CoolDrawer will be
powered off in the off cycle.
840653
21
Do Fisher and Paykel recommend a brand and model of inverter to use? - No.
Due to the large number of brands and models, it is impractical, not to mention inappropriate, for us to
attempt to approve or disapprove the use of any particular inverter. We simply recommend that everything
possible is done to ensure any inverter used complies with the preceding technical recommendations.
Do Fisher and Paykel provide a guarantee for CoolDrawer electronic modules when run from an inverter
supply? - No.
Even though the design of inverters has improved immensely over the last few years, and the incidence of
reported problems is very low, we do not know the “quirks” of individual inverters. Should an inverter output
go outside our voltage recommendations then it may damage the CoolDrawer Electronics and this,
obviously, is beyond our control.
4.3 Using A Motor Driven Generator Supply
Motor driven generators typically generate a 230V rms. sinusoidal voltage output. Whilst the voltage shape
is better defined than an inverter, a generator can still develop high voltage pulses due to such things as:
• Noise of brushes.
• Surges due to other equipment coming on/off line.
• Surges due to start up - power down.
As such, the same technical recommendations as have been outlined in the preceding inverter supply
section are an excellent guideline if planning to use a generator supply. Please read these technical
recommendations thoroughly.
4.4 Summary
As has been already mentioned, there are many successful installations where customers are using
inverters or generators to power their refrigerators.
If our technical recommendations for inverters/generators are adhered to, we are not aware of any reasons
why operational or reliability problems should be experienced.
