Raypak XPAK 85 - Manual (Page 5)

5
Observe these instructions as general warnings:
– Chemicals used to clean the system and/or inhibit corrosion
must be pH neutral, i.e. they should ensure that the level of the
pH in the system water remains neutral.
Premature failure of certain components can occur if the pH
level in the system water is out of normal levels.
– Raypak recommends that an inhibitor - suitable for use with
aluminum heat exchangers - is used to protect the boiler and
system from the effects of corrosion and/or electrolytic action.
The inhibitor must be administered in strict accordance with
the manufacturers instructions.
– A properly sized expansion tank must be installed in the boiler
system. No valve is to be placed between the boiler and the
expansion tank.
– When the boiler has been filled for the first time or the system
has been drained and refilled, it will be necessary to purge
any air that may have become trapped within the appliance
heat exchanger.
NOTE : Glycol in the system must not exced 40%.
Observe these instructions for space heating water:
– Thoroughly flush the system prior to filling.
Only use untreated main water to fill and top off the system.
– Do not use water softners in the system.
– Do not use inhibitors or other additives!
– The maximum permissible flow rate of the XPAK 85 this is 5.7
GPM (1,300 ltr/hr), for the XPAK 120 is 6.2 GPM (1,400 ltr/hr).
– When using oxygen-permeable pipes, e.g. for floor heating
systems, you must separate the system using heat exchangers.
Unsuitable heating system water promotes the formation of
sludge and corrosion. This may damage the heat exchanger
or affect its operation.
– A properly sized expansion tank must be installed in the boiler
system.
Tools, materials and additional equipment
For the installation and maintenance of the boiler you will need
the standard tools for space heating, gas and water fitting.
In addition, a handtruck with a fastening belt is very useful.
Disposal
– Dispose of the boiler packaging in an environmentally sound
manner.
– Dispose of components of the heating system (e. g. boiler or
control device), that must be replaced, by handing them in to
an authorized recycling facility.
DANGER
if flammable gas explodes.
Beware if you smell gas: there may be an explosion hazard!
Warning: If the information in these instructions is not followed
exactly, a fire or explosion may result causing property
damage, personal injury or death.
- Do not store or use gasoline or other flammable vapors and
liquids in the vicinity of this or any other boiler.
What to do if you smell gas
- Do not try to light any boiler.
- Do not touch any electrical switch; do not use any phone in your
building.
- Immediately call your gas supplier from a neighbor’s phone.
Follow the gas supplier’s instructions.
- If you cannot reach your gas supplier, call the fire department.
Installation and service must be performed by a qualified installer,
service agency or the gas supplier.
