8.1 Set-up
NOTICE: THE UNIT SHOULD BE LOCATED IN AN AREA WHERE
WATER LEAKAGE FROM THE UNIT OR ANY CONNECTIONS WILL NOT
RESULT IN DAMAGE TO THE AREA SURROUNDING THE UNIT.
DANGER: THE UNIT MUST NOT BE LOCATED NEAR FLAMMABLE LIQUID
SUCH AS GASOLINE, ADHESIVES, SOLVENTS, PAINT THINNERS, BUTANE,
LIQUIFIED PROPANE, ETC. AS THE CONTROLS OF THIS APPLIANCE COULD
IGNITE VAPORS CAUSING AN EXPLOSION.
Inspect the packaging for damage and remove packaging at the
installation site. Verify presence of six brass thread to sweat fittings.
The installation site must be structurally capable of supporting the
weight of the tank when filled. The location has to be above freezing.
The water drainage pipe must be freeze proof.
8.2 Connection
Refer to Figure 1 and Figure 2.
8.3 Heater Installation
The installation of the hydronic loop is shown in Figures 4 & 5. The
circuit must include a Temperature / Pressure Relief Valve, and air-
vent, a check valve, and an expansion tank.
8.4 Hot Water Installation
8.4.1 Local Site Conditions
Prior to installation check that the local conditions are compatible
with the appliance design, especially that the maximum working
excess pressure of 150 PSI (10 bar.) is not exceeded.
8.4.2 Required Pipe Combinations
A steel or a copper pipe with insulation can be used for the hot
water connectors. Copper pipe with insulation is especially suitable
due to its low heat loss.
Required combinations:
Cold water pipeline Hot water pipeline
Copper pipe Copper pipe
Steel pipe Steel or copper pipe
Plastic pipe Steel or copper pipe
8.4.3 Cold Water Supply Safety Components
All safety components must be installed into the cold water supply
(Fill & drail valve, Check valve, isolating ball valve & pressure
regulator, see Figures 4 & 5). The order of the individual fittings must
be in accordance to local regulations.
8.4.4 Pressure Regulator Settings
The pressure regulator has to be set to 150 PSI (10 bar). It can
only be installed into the cold water supply. The supply has to be
thoroughly inspected prior to installation. Installation of dirt filters
or any other narrowing of the supply line to the pressure relief valve
is forbidden.
The temperature & pressure relief valve has to be easily accessible.
Expansion water generated during the heating has to flow visibly to
a drain. The drainage pipe must be large enough to accommodate
water drainage with a fully opened T & P valve. The drainage pipe
must be protected from freezing and must not lead outdoors.
The pressure regulator (Figures 4 & 5) has to be set so no water
drips from the T & P valve.
Heavy dripping of the T & P valve can be caused by dirt in the valve
seat or water pressure. Water pressure needs to re regulated below
150 PSI.
8.4.5 Before Filling
Prior to filling all screws must be tight.
8.4.6 Drainage and Re-circulation
Drainage of the hot water tank is via the fill & drain valve (Figures 4
& 5).
A re-circulator can be attached to a separate socket across the
thermometer. Drill the outer casing with a hole saw
Ø
50 where
marked and remove insulation from the socket in that area.
For energy conservation, use of a circulator is not recommended.
