SPIROCROSS INSTALLING AND OPERATING INSTRUCTIONS
Congratulations! With this SpiroCross you have bought a product that will definitely
improve the quality of your complete installation.
This instruction applies to product types starting with X, except for X*S (fig. 1A, ).
Manufacturer: Spirotech bv, Helmond - The Netherlands
This SpiroCross is designed and manufactured according to the Sound Engineering
Practice as stated in the Pressure Equipment Directive (97/23/EC)
CAUTION
• This instruction must be given to the end user, who should keep it.
• Take into account local regulations.
Application
Hydraulically balance / separate the primary and secondary flow in the installation, in
combination with the (fully) automatic removal of air, gasses and dirt from water and
water/glycol mixtures (max. 40%). Not suitable for demineralised water, drinking water,
and dangerous or inflammable substances. Can be used in combination with chemicals
/ inhibitors approved according to local directives. Please check that it is compatible
with the materials used to construct your installation. For more information contact your
supplier.

CAUTION
• Installation and maintenance may only be carried out by a qualified installer.
• When working on the SpiroCross always ensure there is no pressure in the
installation and let it cool down.
• Touching the product "in operation" may cause burns.
• Never use the drain valve for (re)filling.
Handling the SpiroCross (fig. 1B)
Pay particular attention to the following safety procedures when lifting the SpiroCross
from its packaging:
• Use approved lifting chains / straps with safety hooks.
• Make sure that the lifting chains / straps are tight before lifting the SpiroCross
• Do not stand under the load
• Make sure the SpiroCross can move freely.
Installing the SpiroCross
The SpiroCross should be installed vertically, with the air vent on top, between the prima-
ry side (boiler/chiller side) and the secondary side (system side) of the installation. For
heating installations the upper connections should be mounted to the system flow line,
the lower connections to the return line. For cooling installations the lower connections
should be mounted to the system flow line and the upper ones to the return line.
• The SpiroCross should be installed stress free and with the body vertical.
• The SpiroCross should not be used to support pipework.
• The SpiroCross should not be modified in any way, nor should it be welded to, other
than necessary for mounting the SpiroCross into the installation.
• The lifting lugs may only be used for handling during installation.
• Apply the separately supplied product labels if the labels on the product are not visi-
ble, e.g. after the unit has been insulated.
• The unit operates independent of the flow direction .
• Fit the supplied drain valve at the bottom of the SpiroCross, shut off the valve and
mount the safety plug . (for XC050 - XC080: temporarily remove the handle from
the drain valve before fitting it)
• Don't obstruct the vent valve and keep valve accessible.
• A tube can be fitted to the air vent to lead away the released (smelly) air. Excessive
dirt particles or foam forming might cause a temporary leakage of the vent valve .
• Maximum allowable hydraulic test pressure: 1,5 x maximum working pressure ().
• If the installation is tested with compressed air, the SpiroCross should be shut off
temporarily with a cap R½ (not supplied) . Take care: cap R½ must be removed
before commissioning the installation.

Draining dirt from the SpiroCross
After commissioning the SpiroCross must be drained off frequently by a qualified instal-
ler, to remove the collected dirt, according to the procedure below. Proper and regular
draining will ensure correct functioning of the separator and maximize the life time ex-
pectancy as well as a trouble free operation of the unit and system. Regular analyses of
the system fluid will help to take the right measures to maintain the correct fluid quality
and consequently system performance.
CAUTION
• Water may be hot!
• Try to restrict the amount of water drained off as much as possible.
• Check the installation pressure after draining and refill if necessary.
• Remove the safety plug .
• Fit a hose or a permanent connection resistant to the pressure and temperature con-
cerned, to discharge the installation water into a suitable place.
• Open the drain valve gradually for a short period.
• As soon as no dirt is drained off anymore, close the drain valve .
• Fit the safety plug .
Failures
• At initial use the vent valve might drip a little. This will stop after a short period of
time.
• Always contact your installer in case of malfunction.
• In case of leakage of the vent valve , the complete deaeration cap must be repla-
ced.
Guarantee
• 5 years after the date of purchase.
• Incorrect installation or incompetent use or repairs may render the guarantee invalid.
• Damage or losses resulting from failures are not included in the guarantee.
• Normal tear and wear are excluded from guarantee.
Alterations reserved.
