1. Safety
Every effort is made to ensure that products can be used safety, but it is essential
that all users should be aware of the hazards present and act accordingly. The
following information must be bought to the attention of all persons involved with the
equipment. This handbook refers to a:
Ever Cool Pressurized Temperature Control Unit.
Many parts, including external ones such as hose connections and filters are hot
during operation. Such parts remain hot for some time after the equipment has been
switched off. They may cause blistering or burns if touched before they have had
time to cool.
The temperature controller is electrically powered at mains voltage. It must be
correctly earthed in accordance with the installation section of this handbook and
with local regulations for electrical supply. All electrical and mechanical interlocks,
guards and other safety devices fitted when delivered must be kept in place. They
must be inspected at regular intervals by competent personnel.
Examinations or repair must not be attempted by untrained persons. The equipment
must be completely isolated from the electrical supply and all parts allowed to cool
down, including those surrounded by thermal insulation, before any covers are
removed. The equipment must not be adjusted or modified for use in a non –
standard manner without first seeking advice from Ever Cool Limited.
All hoses and ancillary devices connected to the equipment must be of suitable
quality to withstand the operating temperature and internal pressure specified in this
handbook.
Flexible hoses connected by the user should be installed according to the re –
commendations of the hose manufacturer, especially in regard to minimum bending
radius, and care should be taken to avoid wear or damage during use.
All pipework, particularly flexible hoses, valves and other apparatus should be
inspected regularly by qualified personnel. Equipment should be taken out of service,
until rectified, at any sign of damage of leakage.
In certain circumstances, internal pressure may be present with sufficient force to
cause injury. No part of the fluid circuit, whether internal or external to the
equipment, should be released until the temperature of all parts is at 50°C or below.

2. General Safety Precaution (During Servicing)
Disconnect from supply
Secure against re –activation
Confirm de –energisation
Cover or provide barriers for adjacent live components
Never stand on temperature controller –always access ladders, it may be
considered necessary to provide protection to personnel form any leakage
however caused. Equipment design is under constant review and changes
may be made to improve quality. If any other information is required, or if
there is any doubt regarding safe installation or application of the equipment,
please contact: Ever Cool Ltd on +44(0)208 601 7157.
3. Noise Emissions
For assessment of the noise levels in the work area in which the unit is to be
used the following information is provided:
PRESUMED NOISE LEVEL POWER = LWA 80 (ISO 3746)
4. Introduction & General Description
Each temperature control unit has been designed for efficiency and ease of
operation with high reliability. It is one of a range of similar products designed to
cover very diverse performance needs in process temperature regulation.
This handbook gives details of design, operation and maintenance for the TC 140
pressurized unit.
DO not begin installation or servicing without being sure of the model and the
operating voltage (look at the front panel and serial plate on the back).
5. The Fluid Circuit - Water Unit
MAXIMUM WATER INLET PRESSURE FOR TC 140 (Pressurized units) IS 4 BAR
IMPORTANT: REDUCE PROCESS WATER TEMP TO BELOW 50°C BEFORE
REMOVING HOSES.
IMPORTANT: DRAIN THE UNITS BEFORE YOU TAKE OUT THE PROCESS
HOSES

6. Heating & Cooling
Heating elements are made from low watts density incoloy to present undue built up
of scaling. The heat exchanger (COOLER) is a weld plate to minimize the effect from
uneven expansion and to give a large cooling surface for greater performance.
7. The Fluid Pump
The pump is of Magnetic Drive Pump.
8. The Electrical System
Some details of the electrical system, for maintenance purposes, are in the date
sheet of this manual. Please note: the control voltage is 24V. Always check carefully
before fitting replacement parts.
Power ON/OFF is the RED handle on the front panel which interlocks with the mains
isolator.
All control switches are LED indicators are identified by icons for easy recognition of
functions and faults.
Heater and pumps contactors and pump overload are all housed in the self
contained electrical cabinet. This lies behind the front panel which hinges
downwards for easy access.
Heating and cooling functions are switched on and off automatically by the printed
circuit board. This is achieved with a hybrid PCB circuit board and a J type
thermocouple.

9. Installation - Water Unit
Connecting up and filling with water
Position the unit as near as possible to the equipment to be controlled
A. Connect the “water inlet” at the back of the unit to the factory mains or chilled
water supply and the “drain outlet” to a drain, using suitable hoses (refer to
the drawing of rear panel hose connections).
B. Check that the process circulation and external pipework is clean and free
from lime or particulate matter which could reduce heat transfer or damage
the pump. Clean out if necessary. Connect the “to load” and “from load”
connections at the back of the unit using hoses which MUST BE SUITABLE
for operating temperature and pressures as follows:
FOR 140°C UNITS –HOSE RATING (minimum) = 150°C AND 6 BAR
C. Ensure that the panel mounted isolator is switched off, the front panel is
hinged at the bottom and will swing forward and down.
D. Connect the terminals of the unit’s mains isolator to a suitable electrical
supply (check serial plate at back) by means of an appropriately rated power
cable and connect the earth. Electrical connections must be carried by a
professional personnel.
E. If external isolation valves have been fitted, open them to admit mains water
to the unit. Also ensure that all connections to process and drain are open.
N.B
In normal condition the pump will run in a CLOCKWISE direction when viewed
from the front through the motor vent. If the pump is running in an anti –
clockwise direction swap two phase connections over.

10. Starting Unit
Fill the tank until the LED (minimum level) is extinguished. The unit
will fill automatically from the cooling water supply.
Check hose connections are tight and switch on the pump.
On initial start-up the pump may start and stop automatically due to pressure build
up in the system.
Less than 80°C the unit will automatically bleed air through BLUE HOSE.
Cooling water will flow through heat exchanger to keep away scaling build up in the
heat exchanger.
With the pump selection switch in the O (central) position, neither the pump nor the
heating will function.
11. Inputting Set Temperature Value
Upon switching on the unit, the set temperature value and the measured process
value will appear in the digital display.
Press < and the first digit to be set will flash. Press keys to set the value and to
confirm the data. Repeat the operation for the other digits.
AUTOTUNING function (automatic search temperature)
Pressing during 10 seconds T sign will appear in the display when this sign
disappears the unit will have the suitable parameters for one precise process
temperature.
12. Adjusting Additional Control Parameters
It is not normally necessary to change any control parameters other than the set
temperature value as described above. However, the electronic circuit of the unit has
six additional control parameters from SET 0 to SET 8.
To change the set values to additional SET control parameters, press and
simultaneously for 25 seconds, will visualize the first SET press to go the
wanted SET press will appear the first valve, press again to allow change dates
press and the first digit to be set will flash modify it with keys press
confirm.
