Pressure Relief Valve - Truma AquaGo basic Operating Instructions Manual

• 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, insula-
tion, 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 approxi-
mately 0.4 gallons/min (1.5 liter/min) and the
faucet is closed, the burner is automatically
switched back off.
The AquaGo™ comfort and AquaGo™
comfort plus models are equipped with a cir-
culation pump. The circulation pump as well
as the burner are switched on automatically by
the control unit in order to keep the water tem-
perature above a certain level (102 °F (39 °C)
in "Comfort" mode and 41 °F (5 °C) in "ECO"
mode).
The AquaGo™ comfort and AquaGo ™
comfort plus models permit operation without
the risk of freezing even at temperatures of
-4 °F (-20 °C).
• Only the Truma AquaGo™ instant water
heater will be protected from freezing. Cold
water lines, the water tank and the external
water valves may freeze. The vehicle must
be heated separately.
A constant supply of power (12 V), propane
gas, and water is needed during low-tempera-
ture operation.
To conserve gas and power, use the
"ECO ON" switch position. This will main-
tain a temperature above 41 °F (5 °C) in the
Truma AquaGo™ instant water heater. For
maximum comfort (rapid availability of hot wa-
ter at the faucet), use the "ON Comfort" switch
position. This will maintain a temperature above
102 °F (39 °C) in the appliance.
The AquaGo™ basic model does not have frost
protection and shall therefore not be used or
filled with water when there is a danger of
freezing.
