Water Supply - Hydrotech HDS Serie Mode D'emploi

INSTALLATION & PREPARATION

WATER SUPPLY:

Pressurized Supply:
1. Select a water supply hose which is a quality grade of garden hose
measuring at least ¾" ID and no longer than 50 feet.
2. Ensure the water strainer is clean and free of obstructions. Check float
tank for any foreign objects or debris. If water flow becomes restricted
to the pump, cavitation can occur which will cause premature failure of
the pump packings.
3. Connect one end of the water supply hose to the float tank inlet and
connect the other end to the pressurized water supply.
NOTE: If there is a high mineral content in your water, it is recommended
that a water softener be used to prevent the possibility of excessive scale
buildup inside the heat exchanger coil.
4. Follow the incoming water requirements listed below:
a. Water pressure must be between a minimum of 40 PSI
and a maximum of 65 PSI.
b. Incoming GPM must be approximately one gallon more
per minute than the outgoing GPM stated on the
machine nameplate. (You can check the GPM of your
source by timing the filling of a 5 gallon container.)
c. Incoming water temperature must not exceed 125°F.
Excessive pump damage may result if the water
temperature exceeds this level.
5. Never allow the unit to operate without the incoming water line attached
and the water supply completely turned on.
Non-pressurized Supply (Auxiliary Tank):
1. Connect hose from auxiliary tank to open port on the 3-way ball valve.
2. Use the selector lever on the ball valve to allow water to flow from the
auxiliary tank to the pump.
3. The water level in the auxiliary tank must always be higher than the pump
inlet. This will ensure gravity feed of water to the pump. Failure to keep
the water level above the pump inlet will result in the pump running dry
and damage to the wet end of the pump.
