– Drill a hole (18 mm diameter) in the floor of the vehicle.
– Attach drain tube (4) to drain connection, insert both
through the floor and route outside.
– Seal gap between drain hose and hole with plastic body
sealant from below.
– Fasten FrostControl with two screws B 5.5 x 25 (included
with delivery).
Connection of the water pipes
Connect cold water supply to FrostControl. To guarantee the
correct function of the safety/drain valve, the water hoses
(pipes) need to be installed without tension.
Ensure that the cold water supply does not come into
contact with cold bridges (e.g. the outer wall) in order
to prevent freezing.
Water hoses (pipes) need to be installed as short as possible
without kinks.
Installation with flexible hoses (dia. 10 mm)
All hose con nections must be secured with hose clamps
(also cold water hoses)!
Installation with fixed pipes (dia. 12 mm)
We recommend using John Guest pipes, insertion sleeves and
spring washers.
When connecting to a central water supply (rural or city
mains) or if using more powerful pumps, a pressure reduc-
tion valve must always be installed which prevents pressures
above 2.8 bar from developing in the water heater.
Before the pressure relief valve in FrostControl triggers, warm-
ing of the water and its resulting expansion may cause pres-
sure of up to 3.8 bar to occur (also possible with immersion
pumps).
Route all water lines so they drop down to FrostControl!
There shall be no guarantee claims for damage
caused by frost!
