If there are any cavities in the area of the cowl, pack these
with pieces of wood so as to be able to tighten the screws.

Cut out trim strips or such on the vehicle or place supports
beneath them so as to make the cowl lie flat.
Place a support beneath the heater if the walls are sloping. An
angle of inclination of 10 degrees is not to be exceeded.
Insert heater with cowl body (Fig. 8-1) through the wall cut-
out (Fig. 8-2), allow approx. 5 mm to project out of the wall.
Mount sealing frame (Fig. 8-3 – the anti-twisting device en-
sures correct fitting!). Pre-drill holes for the 6 fastening bolts
(Fig. 8-4).

Remove sealing frame (Fig. 8-3) 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
(Fig. 8-1) as well as towards the outside wall!
Fasten sealing frame (Fig. 9-3) to the cowl body using 4
self-tapping screws (Fig. 9-4).

Seal the gap between the hole (Fig. 10-6) and the condensa-
tion tube(Fig. 10-7) with non-hardening mastic – do not use
silicone!
Mount the grille (Fig. 10-8). Press the entire cowl assembly
onto the vehicle wall and fasten with 6 screws (Fig. 10-5).
Screw the Truma UltraRapid securely to the floor of the
vehicle with all three shackle plates (Fig. 10-9a) and the ad-
ditional sheets (Fig. 10-9b) with the screws provided, B5.5 x
25, on suitable base (plywood panel, laminated wood strips
or metal base).
Water connection
Instructions for a proper water system
– All pressure and submergible waterpumps can be used for
operating the water heater.
In order to guarantee complete emptying of the water
and to prevent pressures of greater than the maximum
working water pressure occurring in the Truma UltraRapid, the
enclosed pressure reducer (Fig. 11.-10), water connectors
(Fig. 11.-12 + -13), drain valve (Fig. 11.-14) and : P&T relief
valve (Fig. 11.-23) must be used!
When using pressure pumps with high switching hysteresis,
hot water may flow back through the cold water tap. To pre-
vent backflow, we recommend that a non-return valve (nrv –
not included in the scope of supply) be fitted between the
outlet to the cold water tap and the drain valve.
