Davey HP, HS & HM Pressure Systems with Presscontrol - Manual (Page 4)

Choosing a Site
Choose a site with a firm base and as close to the water source as possible with
correct power supply. Make sure your pressure system is always connected to an
adequate, reliable source of clean water.
Housing your Davey Pressure System
To protect your pressure system from the weather, make sure the pump house is
both water proof, frost free and has adequate ventilation. The pump should be
horizontally mounted on a firm base allowing for drainage, to avoid damage to
flooring etc., that over time may occur from leaking pipe joints or pump seals. Do
not mount the pump vertically.

WARNING: Some insects, such as small ants, find electrical devices
attractive for various reasons. If your pump enclosure is susceptible to
insect infestation you should implement a suitable pest control plan.
Maintenance
The only regular attention your new pressure system may require will be if you
have used an additional pressure tank. You will need to check the pressure tank’s
air charge every 6 months. This can be checked at the air valve with a tyre gauge.
Do not charge tank to a higher pressure than 135kPa for HP models or 195kPa for
HS models.
To check air pressure in tank:
1. Switch off pump.
2. Open outlet nearest to pump to release water pressure.
3. Charge tank to required pressure using air pump and check with tyre gauge.
4. Switch on.
5. Close outlet.
WARNING : Under no circumstances should the Presscontrol be
disassembled. Failure to observe this warning will expose persons to
the possibility of personal injury and may also result in damage to other
property. Do not dismantle, no user serviceable parts, spring under
pressure.
