Electrical installation
The CuddleBlanket system should be installed by a competent person. The electrical connections
should be made using the 13A plug and lead supplied. An IEC socket is fitted on the side of the unit.
Ensure the supply is according to the electrical requirements stated on the serial number label on the
rear of the unit. This label identifies the voltage/frequency and the maximum current.

Quick Start Guide
We would strongly advise that at least 3 hours has elapsed between the deceased’s passing and use
of the cooling system. The reason is that the body will still be very warm and you will be fully insulating
the deceased so it is strongly advised to let the deceased undertake some natural cooling for a few
hours.
1. Setting up the CuddleBlanket
Ensure unit is switched OFF at the rocker switch adjacent to the power cord
socket. Plug in the electrical cable ensuring the unit is kept flat and in a well-
ventilated area. If the room is small then it is best to leave adjoining doors
open where possible.
2. Connecting the hose
Plug the 2 male connectors of the long blue insulated hose firmly into the ports
on the side of the unit. You will hear a click. It does not matter which way round
you connect the hoses to the unit.
3. Connecting the cooling pad
Place the cooling pad over the deceased, just below the neck. We recommend
placing a sheet over the deceased first. Then use another sheet over the
cooling pad before using the supplied insulated duvet. This will help with
cleaning and any condensation that may build up. You can place any blanket or
cover over the supplied duvet, it will not affect the system. Ensure the duvet is
tucked around the deceased to minimise warm ambient air reaching the cool
pad.
4. Switch on the CuddleBlanket
Switch the CuddleBlanket ON using the black rocker on/off switch adjacent to
the power cord socket.
5. You may need to top up the CuddleBlanket with cooling fluid (Coldflow2)
Fluid will begin to circulate from the CuddleBlanket through the hoses and to
the cooling pad. The fluid level within the reservoir window may begin to drop
and the alarm may sound briefly. For additional ColdFlow2 fluid, please contact
No alarm - the CuddleBlanket is fully operational; please move to stage 6.
Alarm sounds - Do not turn off the unit, unscrew the filler cap and continuously
fill the unit with Coldflow2 cooling fluid using a jug or funnel, avoiding spillage
onto the unit. Fill approximately to the red line shown on the reservoir window.
Model HC170. Issue Number 8. Date 17.01.2022. 4
6. Setting the temperature
The machine will remember the temperature it was set to during its last operation.
Don’t need to change the temperature? Please move to stage 7.
Need to change the temperature? Follow the 3 steps below. The display will run through a self-test programme
for the first few seconds after switching on the system, this is normal.
1. Press the ‘P’ button on the display once. ‘SP-1’ (set point) will be displayed in red at the top of the display.
2. Using the up and down arrow, select the required temperature in green. 8-10°C is usual.
3. Press the ‘P’ button again to set the system. The machine will cool the circulating fluid to this
temperature The temperature of the fluid is shown by the red display and the green shows the set point.
7. Turning off the system
Switch off the unit at the black rocker switch, remove the hose (the alarm will sound which is normal) and
unplug the machine. A few drops of the fluid will be lost from the connectors, this is normal.
IMPORTANT: Always allow the cooling pads to warm back up to room temperature before folding to pack away
as this will increase the life of the pads.
8. Warning lights, alarm and topping up the CuddleBlanket unit with Coldflow2 fluid
The alarm will sound and the red LED light will illuminate if there is an obstruction to flow or if the reservoir is
low on fluid. (Fig.1)
The reservoir should always be kept topped up during operation. Leave the unit switched on, remove the filler
cap and top up slowly. (Fig.2)

Troubleshooting
Condensation on the cooling pad or the deceased
The cooling pad gets very cold in use. When there is a large temperature difference to the pad and the
surrounding ambient air a small amount of condensation on the pad is normal.
There are 2 ways to reduce this:
1. Ensure there are no gaps in the insulated duvet allowing the ambient air to reach the pad.
2. Increase the temperature of the machine (e.g. change from 8°C to 10°C).
The alarm is sounding and the red LED is illuminated
• Check the connection of the hose to the CuddleBlanket. Refer to section 2
• Check that the hose or cooling pad are not kinked or deformed.
• Check that there is fluid in the unit. Refer to section 5.
If the alarm is still sounding:
• Locate the supplied ‘loop back’ short test hose as shown. (see fig.3)
• Remove the blue hose from the unit and replace with the ‘loop back’. (see fig.4)
• Loosen the filler cap to allow any trapped air to escape.
• Turn on the unit.
• If the alarm stops with the loop back fitted, check the cooling pad and blue hose, reconnect
them and retry.
• If the alarm continues, contact Flexmort:

Unpacking and Positioning
Unpacking the CuddleBlanket
Before unpacking the CuddleBlanket unit, inspect the blue packing case for any signs of damage.
Carefully remove unit from packing case. Check unit for signs of transit damage.
If transit damage is discovered, immediately inform both the delivering haulage company and
Flexmort in writing. Take photographic evidence and retain all packaging materials.
Please observe all local and governing recycling requirements when disposing of packaging materials.
Positioning the Equipment
• The equipment must only be positioned indoors.
• The CuddleBlanket chiller unit must be kept upright at all times.
• The equipment must be positioned on a level surface.
Model HC170. Issue Number 8. Date 17.01.2022. 7
• Avoid positioning in an area where other plant operations create a high ambient temperature.
The chiller will operate most efficiently in ambient temperatures up to 23°C
• The equipment must be installed in a well-ventilated area. Avoid obstructing the air grilles as
these allow fresh air to enter the unit and warm exhaust air to escape.
Note: Recirculating hot exhaust air will adversely affect the performance of the coolant
