Installation
Note: Some of the following manual sec-
tions contain information in the form of
warnings, cautions and notes that require
special attention. Read and follow these
instructions carefully to avoid personal injury
and damage to the instrument. Only quali-
fied personnel should conduct the instal-
lation tasks described in this portion of the
manual.
Environmental Conditions
The 6200 Calorimeter is completely assembled and
given a thorough test before it is shipped from the
factory. If the user follows these instructions, instal-
lation of the calorimeter should be completed with
little or no difficulty. If the factory settings are not
disturbed, only minor adjustments will be needed to
adapt the calorimeter to operating conditions in the
user’s laboratory.
This apparatus is to be used indoors. It requires
at least 8 square feet of workspace on a sturdy
bench or table in a well-ventilated area with con-
venient access to an electric outlet, running water
and a drain. The supply voltage must be within ±
10% of marked nominal voltage on the apparatus.
The supply voltage receptacle must have an earth
ground connection.
Required Consumables, Utilities and Power
Requirements
The 6200 Calorimeter System requires availability of
Oxygen, 99.5% purity, 2500 psig maximum.
The power requirements for the subassemblies of
the 6200 Calorimeter are:
Calorimeter
120VAC, 6.0 Amps. 50/60 Hz
240VAC, 3.0 Amps. 50/60 Hz
Printer
100 to 240 VAC, 0.35 Amps 50/60 Hz
Printer Supplies
334C Printer Paper
335C Printer Ribbon
Filling the Jacket Reservoir
The water reservoir of the calorimeter must be filled
with approximately 1.4 liters of water (distilled or
de-ionized preferred). This must be done prior to
turning on the heater and the pump. The reservoir is
filled through the tank fill elbow on the back of the
calorimeter. The tank is full once water stands in the
horizontal run of the filling elbow.
Power Connection
Plug the power line into any grounded outlet provid-
ing proper voltage that matches the specification
on the nameplate of the calorimeter. The calorim-
eter will draw approximately 300 watts of power.
Grounding is very important not only as a safety
measure, but also to ensure satisfactory controller
performance. If there is any question about the
reliability of the ground connection through the
power cord, run a separate earth ground wire to the
controller chassis.
Turn the power switch to the on position. After a
short time, the Parr logo will appear on the LCD
display followed by a running description of the
instrument boot sequence. When the boot sequence
is complete, the calorimeter Main Menu is dis-
played. Go to the Calorimeter Operation page and
turn the heater and pump on. This begins circulating
and heating the calorimeter jacket water. Add water
to the filling elbow at the rear of the instrument as
required in order to keep it full.
Jacket Cooling Water Connection
It becomes necessary to use the jacket cooling water
connection only if the calorimeter operating room
temperature exceeds 24 °C (75 °F).
When required, an external water source is used to
cool the jacket of the 6200 Calorimeter. This is done
in either of the following ways:
1. Tap water is used for cooling and then run to a
drain.
2. Cooling water is re-circulated to the calorimeter
from a Parr 6510 Water Handling System.
The water that provides the cooling goes through a
heat exchanger and does not mix with the water in
the jacket and its reservoir. There is a very low cool-
ing load and tap water up to a temperature of 27 °C
should be adequate.
