APPLIANCE FEATURES
The hand pump for pressure tests is used to test the
tightness and strength of the systems and receivers
supplied with water, including solar heating systems
supplied with a water-glycol solution.

TECHNICAL DATA

Product No.: YT-24800
Maximum pressure: 5 MPa / 50 bar / 725 psi
Maximum temperature of the test liquid: 50
Nominal capacity of the pump tank: 12 litres
SAFETY REQUIREMENTS
Before starting pressure tests, read the test proce-
dure defi ned in the documentation accompanying the
receiver or the system. Performing the test procedure
incorrectly can damage the tested device and the pump
itself. The manufacturer is not responsible for any dam-
age caused by improper application of the pump.
During the test procedure, use personal protective
equipment such as: safety glasses, protective clothing
with long sleeves and legs. Use protective footwear with
anti-slip soles. Wear protective gloves, too.
During a pressure test, the tested device could unseal,
resulting in ejecting high-pressure water jets. Any con-
tact between an unprotected part of the body with such
a jet of water could lead to skin perforation. Spilled wa-
ter could be slippery, causing the risk of injuries.
The pump can work with water or a water solution of
glycol used in solar heating systems. It is not allowed to
use the pump with any other liquid.
INSTALLATION OF THE PUMP
The pump is mounted by screwing the handle into the
holder. The rear wall of the pump features a rotating
hook, which is used to fi x the handle in the lower po-
sition. Keeping the pump handle in the lower position
provides better protection of the pump's piston.
TEST PROCEDURE
Make sure that both pump valves are open. Turn them
counter-clockwise.
Connect the pump hose to the device under test. Fill the
pump tank with water or glycol-water solution, depend-
ing on the recommendations defi ned in the documenta-
tion supplied with the tested device.

Close the V2 valve by turning it clockwise all the way.
Fill the tested device with liquid and purge it. Close all
valves in the unit.
Start pumping, by moving the handle up and down. Ob-
serve the pressure gauge's pointer to ensure that the
pressure defi ned in the documentation supplied with the
device under test is not exceeded.
When the test pressure is reached, close the V1 valve,
by turning it clockwise all the way.
If a leak develops in the tested device, it will be indicat-
ed by a pressure drop. Follow the instructions provided
C / 122 F in the unit's documentation with regard to test duration
O O
and pressure drop.
After completing the test, open the V1 and V2 valves,
by turning them counter-clockwise. This will reduce
pressure in the system. The pressure gauge's pointer
should point to zero.
Remove water from the pump tank.
MAINTENANCE
Empty the pump's water tank. Close the V2 valve and
start pumping. This will remove any residual water from
the pump's system and from the hose. Dry the remain-
ing water with a soft cloth.
The pump piston connected with the handle should be
periodically lubricated with a water-resistant grease. Do
not allow the pump piston to rust.
Store the pump in shaded, ventilated rooms. Protect the
pump from dust, dirt and other contaminants. Before fi ll-
ing the pump with water, thoroughly clean the inside of
the tank. Contamination from the tank can damage the
system, if it penetrates into the tested system.
