READ THESE INSTRUCTIONS CAREFULLY BEFORE INSTALLATION
LOCATION
1. Pump can be located at the well or can be offset some distance
away from the well. For best performance it should be located
as close to the well as possible. The horizontal distance is the
horizotal measurement between pump suction and the water
source. This distance may affect the ability of the pump to
operate. If over 100', contact the Manufacturer for assistance.
2. Location can be in the basement, a pit below ground or in a pump
house above ground.
3. Ventilation and drainage must be provided to prevent damage
from moisture to the motor and pressure switch.
4. The pump and all piping must be protected from freezing.
5. Pump and pipe line must be drained when not in use if there is
any danger of freezing.
WELL CONDITIONS
1. New wells should be pumped clean of all sand and foreign matter
before installing the pump or damage may result to the operating
parts.
2. The foot valve should be installed a minimum of five (5) feet
from the bottom of the well to prevent sand, mud or other foreign
matter from entering the system.
3. The well must be capable of furnishing a sufficient quantity of
water to satisfy the demands of the pump and personal needs.
The water level must not draw down below the maximum rated
depth of the pump or loss of capacity and prime will result.
4. For weak well installations, see Paragraph #1 under Deep Well
(Double Pipe System) Installations (Page 5).
5. For sanitary reasons, install a well seal or pitless adapter as
required and in accordance with local and state codes.
PIPING
1. Old or badly scaled pipe should not be used because dislodged
flakes of scale can cause stoppage of the ejector nozzle and
malfunction the entire system.
2. Use only pipe in good condition free from rust and scale.
Threads should be sharp, cleanly cut with a minimum of two (2)
threads remaining when connection is completely drawn up.
3. On galvanized steel pipe installations, the ends should be
reamed to insure maximum capacity.
4. All joints and connections should be doped (male threads only)
and drawn up tightly.
CAUTION
The entire system must be air and water
tight for efficient operation.
TYPE OF PIPE
1. Plastic or galvanized steel pipe may be used in the installation of
jet pumps.
2. Plastic pipe must have a minimum pressure rating of 160 PSI.
3. Never use flexible plastic pipe and insert adapters on deep well
single pipe ejector applications.
WELL TO PUMP PIPING
1. All offset piping should slope upwards from well to pump.
2. Avoid dips or pockets in offset piping or air will accumulate at high
points which will make priming difficult.
3. Install unions at pump and at well to aid in servicing.
4. Allow enough room around pump and piping installation for using
pipe wrenches and for service and installation.
5. Do not use piping of sizes smaller than those listed in Charts 1
and 2 or pump will not operate properly.
NOTE: For the pump to operate, the venturi tube of the ejector must
be positioned into the top tapping of the face of the pump.
CONTROL BODY AND PRESSURE SWITCH ATTACHMENT
1. To assure leak free connections, use Teflon tape or pipe dope
on all switch and pipe threads. Tighten all connections by hand
plus 1-1/2 additional turns.
2. Use pipe dope on external threads of all plumbing connections.
