SEALS AND INSULATION

Insulation and sealing materials are used in the construction

of the Electrastream cylinders. Units are sealed and when

used in the manner for which they are intended the insulating

and sealing materials do not present any known hazard.

However always observe the following recommendations:-

1. Avoid inhalation of fibres or dust, wear face mask.

2. Avoid eye contamination by fibres or dust - wear eye

protection.

3. As far as possible avoid any skin contact with Fibreglass

Insulation, Glass Rope, Mineral Wool, Insulation Pads and

Ceramic Fibre.

OTHER MATERIALS

SEALANTS, ADHESIVES AND PAINTS

Sealants, Adhesives and Paints are used in the construction of

the Electrastream components. When used in the manner for

which they are intended they do not present any known hazard.

ELECTRICELECTRIC

ELECTRIC

The Cylinder Tri-Core Heater, Pump, Thermostats and Contactor

Box all have electrical supply of 230V (enough to endanger

life).

Always isolate before connection, adjustment, servicing and

repair.

When the Tri-Core Heater cover is removed high power live

electrical terminals are exposed.

ISOLATE THE TRI-CORE HEATER BEFORE REMOVING ITS

COVER.

Earth protection - Earth Continuity Conductors must be fitted

and must comply with IEE Wiring Regulations.

Worked Example

The example below is for a G½ 6 with a discharge pipe (D2)

having 4 No. 22mm elbows and length of 7m from the

tundishtundish

tundish

to the point of discharge.

From Table 1:

Maximum resistance allowed for a straight length of 22mm

copper discharge pipe (D2) from a G½

is: 9.0m

Subtract the resistance for 4 No. 22mm elbows at 0.8m each =

3.2m

Therefore the maximum permitted length equates to: 5.8m

which is less than the actual length of 7m therefore calculate the

next largest size.

Maximum resistance allowed for a straight length of 28mm

copper discharge pipe (D2) from a G½

As the actual length is 7m, a 28mm (D2) copper pipe will be

satisfactory.

3.583.58

3.58 Where a single common discharge pipe serves more than

one system, it should be at least one pipe size larger than the

largest individual discharge pipe (D2) to be connected.

3.593.59

3.59 The discharge pipe should not be connected to a soil

discharge stack unless it can be demonstrated that the soil

discharge stack is capable of safely withstanding temperatures

of the water discharged, in which case, it should:

a. contain a mechanical seal, not incorporating a water trap,

which allows water into the branch pipe without allowing

foul air from the drain to be ventilated through the

tundishtundish

tundish;

b. be a separate branch pipe with no

sanitary appliancessanitary appliances

sanitary appliances

connected to it;

c. if plastic pipes are used as branch pipes carrying

discharge from a safety device they should be either

polybutalene (PB) to Class S of BS 7291-2:2006 or cross

linked polyethylene (PE-X) to Class S of BS 7291-3:2006;

and

d. be continuously marked with a warning that no
