Insert heater with cowl body (1) through the wall cut-out (2),
allow approx. 5 mm to project out of the wall. Mount sealing
frame (3) (the anti-twisting device ensures correct fitting!).
Pre-drill holes for the 6 fastening bolts (4).

Remove sealing frame (3) and coat with non hardening mastic
on the side facing the vehicle – do not use silicone!
The sealing frame must be well sealed with respect to
the front sides and the cross bars of the cowl body (1)
as well as towards the outside wall!
Fasten sealing frame (3) to the cowl body using 4 self-cutting
screws (4).

Screw the sealing frame (3) in contact together
with the cowl body (1) so the anti-twist device
projects out!

Seal the gap between the hole (6) and the condensation
tube (7) with non hardening mastic – do not use silicone!
Mount the grille (8). Press the entire cowl assembly onto the
vehicle wall and fasten with 6 screws (5).
Screw the water heater securely to the floor of the vehicle
with at least two shackle plates (9) with the screws provided,
B 5.5 x 25, on suitable base (plywood panel, laminated wood
strips or metal base).
Water connection
All pressure and submergible waterpumps up to 2.8 bar
and all mixed combination sets with or without an electrical
switch, can be used for operating the water heater.
If connecting to a
central water supply
(rural or city con-
nection) or when using more powerful pumps, a
pressure
reducer
must be used which prevents pressures of greater
than
2.8 bar
occurring in the system.
When using submergible pumps, a non-return valve (10 – not in-
cluded in the scope of supply) must be fitted between the pump
and the first branch point (arrow points in direction of flow).

When using pressure pumps with high switching hysteresis,
hot water may flow back through the cold water tap. To pre-
vent the backflow, we recommend that a non-return valve
(11 – not included in the scope of supply) be fitted between
the outlet to the cold water tap and the drain valve.

When using the Truma Ultrastore together witch the
Truma Ultraflow pressure switch, the use of a non-re-
turnvalve is essential (please refer to the pressure switch
instruction).
In order to guarantee complete emptying of the water
content and ongoing sealing tightness of the water
connections, the enclosed
water connectors
(12 + 13)
and
the
safety (pressure relief) drain valve
(14)
must be used!
John Guest System rigid pipe routing
The water connectors (12 + 13) and safety/drain valve (14)
supplied with the Truma Ultrastore have a 12 mm diameter
fitting and are only approved to use with Original John Guest
piping.
For connecting to rigid pipes with other diameters appropiate
adapters (not included in scope of delivery) must be used.
