1.3.11 Condenser Coil
The unit is fitted with a 3 row coil using 7mm tubing.
1.3.12 Autotransformer
An autotransformer may be provided to allow operation
on 190/230, 3phase, 50/60 hertz power. The
autotransformer raises the supply voltage to the
nominal 380/460 volt power required by the base unit.
The autotransformer may also be fitted with an
individual circuit breaker for the 230 volt power.
If the unit is equipped with an autoransformer and
communications module, the autotransformer will be
fitter with at transformer bridge unit (TBU) to assist in
communications.
1.3.13 Temperature Recorder
An electronic recorder manufactured by Partlow
Corporation may be fitted to the unit.
1.3.14 Gutters
Rain gutters may be fitted over the control box and
recorder section to divert rain away form the controls.
The different gutters include standard length bolted
gutters, extended length gutters and riveted gutters.
1.3.15 Handles
The unit may be equipped with handles to facilitate
access to stacked containers. These handles may
include fixed handles (located at the sides of the unit)
and/or a hinged handle at the center (attached to the
condenser coil cover).
1.3.16 Thermometer Port
The unit may be fitted with ports in the front of the frame
for insertion of a thermometer to measure supply and/or
return air temperature. If fitted, the port(s) will require a
cap and chain.
1.3.17 Water Cooling
The refrigeration system may be fitted with a water
cooled condenser. The condenser is constructed using
copper--nickel tube for sea water applications. The
water cooled condenser is in series with the air cooled
condenser and replaces the standard unit receiver.
When operating on the water cooled condenser, the
condenser fan is deactivated by either a water pressure
switch or condenser fan switch.
1.3.18 Back Panels
Back panel designs that may be fitted include panels of
aluminum and stainless steel. Panels may have access
doors and/or hinge mounting.
1.3.19 460 Volt Cable
Various power cable and plug designs are available for
the main 460 volt supply. The plug options tailor the
cables to each customers requirements.
1.3.20 230 Volt Cable
Units equipped with an autotransformer require an
additional power cable for connection to the 230 volt
source. Various power cable and plug designs are
available. The plug options tailor the cables to each
customers requirements.
1.3.21 Cable Restraint
Various designs are available for storage of the power
cables. These options are variations of the compressor
section front cover.

The unit may be fitted with an upper fresh air makeup
assembly. The fresh air makeup assembly is available
with a Vent Positioning Sensor (VPS) and may also be
fitted with screens.
1.3.23 Lower Air (Fresh Air Make Up)
The unit may be fitted with a lower fresh air makeup
assembly. The fresh air makeup assembly is available
with a Vent Positioning Sensor (VPS) and may also be
fitted with screens.
1.3.24 Arctic Mode
To improve operation in cold ambients, the unit may be
fitted with a crankcase heater. The crankcase heater is
operated, before start--up, to warm the compressor oil
and boil off any liquid refrigerant that may be present in
the crankcase.
1.3.25 Power Correction
The unit may be fitted with a set of power factor
correction capacitors to assist in correction of
imbalance in current draw by the compressor.
1.3.26 Evaporator
Evaporator section options include a semi--hermetic
thermal expansion valve, a hermetic thermal expansion
valve and two sizes of heat exchangers. The unit is
equipped with 6 heaters.
1.3.27 Labels
Operating Instruction and Function Code listing labels
will differ depending on the options installed. For
example, additional operating instructions are required
to describe start--up of a unit equipped with an
autotransformer. Where the labels are available with
additional languages, they are listed in the parts list.
1.3.28 Plate Set
Each unit is equipped with a tethered set of wiring
schematic and wiring diagram plates. The plate sets are
ordered using a seven digit base part number and a two
digit dash number.
1.3.29 Controller
Two different controllers are available:
1. Remanufactured -- Controller is the equivalent of a
