Truma AquaGo® Comfort Plus LP Gas Instant Water
Heater Operation (Model: DLE60CP)
This article provides basic operation instructions for a Truma AquaGo® Comfort Plus LP Gas Instant Water Heater (Model:
DLE60CP).
How It Works
The appliance was developed exclusively for use in
recreational vehicles (RVs). The appliance is connected
between the vehicle’s fresh water supply and its hot
water plumbing system. It is powered by propane and a
12 V power supply. The ventilation grille on the access
door allows combustion air to flow into the appliance and
exhaust gas to flow out. When the appliance is switched
on, the water will be heated on demand:
•
A volume-flow sensor in the appliance detects
when the hot water faucet has been opened and
the volume flow is greater than approximately 0.4
gallons/min (1.5 liter/min). The burner then starts
automatically.
•
The burner control continuously adjusts the heater
output based on volume flow and inlet water
temperature, so that the temperature at the hot water
outlet is approximately 120 °F (49 °C). A temperature
stabilizer is also installed in the appliance to minimize
fluctuations of the outlet temperature.
•
After some time the maximum temperature at the
faucet or in the shower is reached. The length of time
will depend on the model (AquaGo basic, AquaGo
Comfort and AquaGo Comfort plus) and variations
in the water plumbing (length of pipes, insulation,
circulation line, etc.). Like in a home shower, a
comfortable water temperature at the shower head is
reached by mixing in cold water.
•
When the volume flow is less than approximately 0.4
gallons/min (1.5 liter/min) and the faucet is closed, the
burner is automatically switched off.
The AquaGo Comfort and AquaGo Comfort plus models
are equipped with a circulation pump. The circulation
pump as well as the burner are switched on automatically
by the control unit in order to keep the water temperature
above 102 °F (39 °C) in “COMFORT” mode and 41 °F (5 °C)
in “ECO” mode.
Risk of damage in frost conditions.

Access Door
OPENING THE ACCESS DOOR
1. Turn the turn lock counterclockwise into the vertical
position.
WARNING
!
Scalding injury from hot water and/or tampering with
the pressure relief valve! Never actuate the pressure
relief valve as long as the appliance is still hot. Do not
place a plug or reducing coupling on the outlet part of
the valve.
•
The pressure relief valve is a safety component
and must not be removed for any reason other than
replacement.
•
The pressure relief valve is not serviceable; if
defective, it must be replaced.
•
It must be replaced by a Truma pressure relief valve
rated for 100 psi (6.9 bar) that is CSA-certified and
registered.
•
It must be replaced by a Truma certified service
technician.
•
Tampering with the pressure relief valve will void the
warranty.
The appliance is equipped with a pressure relief valve
that complies with the standard for Relief Valves for Hot
Water Supply Systems, ANSI Z21.22
•
The access door can be opened in two different
positions:
❒ Position 1 is the maximum opening width for
switching the appliance on or off.
❒ Position 2 is the starting position for removing the
access door.
2. Open the access door to Position 1.
