Taking out of service
5.2.1 Temporary shutdown
Ɣ
If installed: Switch off the power supply to the ROTEX electric
immersion heater / booster heater.
Draining the storage tank
Ɣ
If installed: Switch off the power supply to the ROTEX electric
immersion heater / booster heater.
a) Without installed solar system:
Ɣ
Remove the safety oveflow from the overflow connection
(see fig. 4-4 to fig. 4-7, item 14) on the hot water storage
tank.
Ɣ
Fit the safety overflow (fig. 4-1, item C) to the filling and
draining connection (see fig. 4-4 to fig. 4-7, pos.15).
Ɣ
Connect the drain hose to the refitted safety overflow.
Ɣ
Drain out water content from cylinder.
b) With installed solar system:
Ɣ
Connect the drain hose to the KFE cock on the solar
regulating and pump unit fitted during filling (RPS3).
Ɣ
Drain out water content from cylinder.
Draining the heating circuit and hot water circuit
Ɣ
Connect the drain hose to the ROTEX heat generator.
Ɣ
Allow the heating and warm water circuit to run empty based
on the suction lifter method.
Ɣ
Disconnect the heating flow and return flow, as well as the
cold water inflow and the hot water outflow ROTEX Sanicube
/ HybridCube
Ɣ
Connect the discharge hose on the heating flow and return
flow as well as the cold water inflow and hot water outflow so
that the hose opening is at ground level.
Check list for start-up
1.

CAUTION!
A heating system which is shut down can freeze in the
event of frost and may suffer damage.
Ɣ
In the event of a danger of frost, start the entire
ROTEX heating system up again and activate the
frost protection function or take the appropriate
frost protection measures for the hot water storage
tank (e.g. by draining).
If the danger of freezing will only last for a few days, the
very good heat insulation of the ROTEX Sanicube /
HybridCube means that it need not be drained, as long
as the storage tank temperature is observed regularly
and not permitted to fall below +3 °C. This does not,
however, provide any protection against frost for the
connected heat distribution system!
If a storage tank temperature of less than +3 °C is
reached, the STB of the electric immersion heater /
booster heater automatically triggers.This prevents
consequential damage to the electric immersion heater
caused by frost when starting up again.
UK only!
CAUTION!
If filling or topping up the storage tank is done by
means of the boiler filling and drain valve, a temporary
filling loop must be used with the appropriate backflow
prevention device in accordance with clause G24.2,
Guidance to the Water Supply (Water Fittings)
Regulations 1999.
