Hydraulic Tests - ACV LCA HP 2000 mh Technical Manual

 To enable the expansion of the water in the water heater, the safety valve must be
fitted with a pipe which will allow this expansion to overflow into a funnel connected
to the drain. Under no circumstances must you reduce its diameter or close this pipe
with a plug or a stop valve. Plugging will invalidate the warranty of the appliance.
 Fitting of a filter on the cold water inlet is strongly recommended in order to
eliminate foreign matter such as sand, gravel, sludge, etc.
 It is imperative to install a T-square on the low pipe of the appliance enabling a direct
transition valve to be fitted in order to carr out shunts a d eli i ate sludge
stagnating at the bottom of the tank.
 Provide a degasser with air drain on the hot water outlet (evacuation of dissolved
gas).
 Equip the water heater with a domestic circulating system for proper
homogenisation of the water volume
 For the purposes of combating Legionella, it is imperative that any thermostatic
mixer is installed as close as possible to the supply points, in order to minimise the
water circuit to 40°, temperature for maximum proliferation of Legionella
 There must be no cutout or regulation system between the tank and the safety valve
4.

HYDRAULIC TESTS


Upon first filling with water, it is down to the installer to verify the seal of the upper flange
and the manhole, and to tighten the bolts if necessary.

After hydraulic connection of all pipes, and before carrying out the electrical cabling,
completely fill the appliance and pressurise it.
Check and rectify the watertightness of each connection.

After each intervention on the hydraulic installation, it is imperative to carry out a
hydraulic seal test
