3. Description
DHG-2 is a device designed to protect the pool water against frost while forcing the filtration pump
to run when there is a danger of freezing due to the outside temperature.
Forcing the pump will move the water around and increase the pressure in the pipes which lowers
the freezing point. Water suction from the main drain will pump the warmer water from the bottom
and warm the water on the surface.
This device can't protect the pipes against frost when outside temperatures are very low and freezing
lasts steadily over days. Users of DHG-2 will not be dispensed from other protection measures like
pipes insulation, wintering floats, even pipes draining.
4. Installation
Put the device at a dry place so that the sensor can measure the outside temperature or the pool water.
Mount the control panel on a dry and even wall with the supplied screws and dowels.

To measure the outside temperature place the sensor away from any heating source or radiation. To
measure the pool water temperature place the sensor on the pipe with clamp saddles and protect it
from surroundings with insulation foam.
Installation of this project involves a hazard of electric shocks. We strongly
recommend you contract a professional installer. Incorrect installation places
you in danger and may irreversibly damage the product and the equipment
connected to it.
5. Connection
A terminal makes the connection of the power
supply, temperature sensor and dry contact for the
pump easy. If DHG-2 has been mounted with a
CCEI filtration panel, the connection to the forced
run of the filtration pump is directly done on ter-
minals A and B in the control panel. If there is no
inputfortheforcedrunforthepumpyoumaycon-
nect the device on the NO contact of the filtration
timer. The power supply of the DHG-2 should be
protected by a 30mA differential protection and
against overload.
6. Settings
DHG-2 displays the temperature when it is powered on. The red light top left on the screen shows
if the forced run is on.
DHG-2 is factory preset to start the forced run when the temperature decreases bellow -2°C and to
stop it when the temperature raises above 0°C.
The set point is the temperature stopping the forced filtration run. The switching point is set at 2°C
bellow this set point.

According to the location of the sensor it may be necessary to modify the set point. It will be shown
by pressing the switch SET.
To modify the set point press the cross up or down until the needed temperature is displayed.
