Computherm DS5-20 User manual

Operating instructions
for the COMPUTHERM DS5-20 and DS5-25
type dirt separators
Contaminants are always present in heating and cooling systems. They
can accumulate over time and can cause clogging, failure, performance
degradation, or noise. To prevent this, dirt must be separated from the system.
The
COMPUTHERM DS5-20 and DS5-25 magnetic dirt separators serve this
purpose, with their design,  lter and strong magnet, they e󰀨 ectively remove both
magnetic and non-magnetic dirt from the heating/cooling systems, allowing the
proper operation of the system and increasing its lifetime.
The products are easy to install and maintain. No need to replace seals or other
parts during maintenance and cleaning. The magnetic dirt separators are much
more e󰀩 cient than conventional  lters and require less maintenance.

The components of the product and the main advantages of its design:
1. Swivel connection, which allows connection to horizontal, vertical or
even diagonal pipes.
2. Shut-o󰀨 valves before and after the product for easy draining.
3. Drain valve to remove dirt.
4. Transparent container to check the amount of dirt collected.
5. Removable strong magnet for easy cleaning.
6. Air vent
Installing the device:
Attention! If you’re using a pacemaker, then special care must be taken whi-
le handling the magnetic dirt separator, similarly as with all strong magnetic
products.
Attention! The strong magnet in the product can damage some electrical
devices. Keep away from these devices to avoid damage.
Attention! Install the product in a dry place which is not exposed to frost and
easily accessible for maintenance.
Attention! For higher e󰀩ciency, the installation diameter of the dirt separator
must match the pipe diameter of the system. The
COMPUTHERM DS5-20 pipe
diameter is ¾” and the DS5-25 pipe diameter is 1”. The use of connection
adapters is not recommended.

Before installation, ensure a suitable location for the dirt separator in the hea-
ting/cooling system. To do this, note the dimensions of the ball valves and the
dimensions of the plugs/connectors. The product can be installed in vertical,
horizontal and skew pipe systems too, but take care that the dirt separator
housing should always be vertical and the drain tap must be located at the
bottom of the product. Make sure that the direction of ow matches the di-
rection indicated on the connector. Install the dirt separator in the return line
upstream of the heater/cooler/pump. Before installation, close the ball valves
on the product, and open them only after installation is nished. After instal-
lation, vent the product using the air vent on its top to ensure proper ow in
the system.
Emptying the collected dirt and venting:
The amount of dirt collected is visible through the transparent cover. When
a visible amount of dirt has accumulated at the bottom of the tank, it is worth
emptying it. It is recommended emptying at least once per heating/cooling
season, even if accumulated dirt is not visible to the naked eye. Follow the
steps below to remove dirt:
• Turn o󰀨 the heating/cooling system so that the uid does not ow in it.
• Close the two ball valves connected to the product.
• Unscrew the magnetic rod from the product and remove it until the end
of the cleaning process.
• Unscrew the closing cover from the bottom of the product
• Open the ball valve located at the bottom of the product with the bottom
part of the closing cover.
• Leave the tap open until the contaminated water leaves the product, then
close the ball valve using the cap and screw the cap back on. If you nd
that not all dirt was drained from the housing of the product, unscrew the
transparent lower part of the product to clean it.
• Place the magnetic bar back into the top of the product.
• Open the two closed ball valves connected to the product.
• Vent the system by opening the air vent on the top of the product. Once
the air is out and liquid is owing out of the air vent, close it.
• If necessary, rell the heating/cooling system to achieve the adequate
water pressure.
• Turn the heating/cooling system on.
