Strack Z7757 Manual

The hand pump for pressure tests is used to lest the tightness and strength of the systems and receivers
supplied with water, including solar heating systems supplied with a water-glycol solution.
Before starting pressure tests, read the lest procedure defined in the documentation accompanying the
receiver or the system. Performing the lest procedure incorrectly can damage the tested device and the pump
itself. The manufacturer is not responsible for any damage caused by improper application of the pump.
During the lest procedure, use personal protective equipment such as: safety glasses, protective clothing
with lang sleeves and legs. Use protective footwear with anti-slip soles. Wear protective gloves, too. During a
pressure lest, the tested device could unseal, resulting in ejecting high-pressure water jets. Any contact between
an unprotected part of the body with such a jet of water could lead to skin perforation. Spilled water 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. lt is not allowed to use the pump with any other liquid.
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 fix the handle in the lower position. Keeping the pump handle in the lower position provides bet-
ter protection of the pump's piston.
