For mounting pump to tank, purchase tank fittings Kit No. 2788.
SEARS Captive Air* Tanks are pre-charged at the factory. Check the
tank Owners Manual to find if air charge needs adjustment. Model
390.251483 and Model 390.251883 require 40 pounds for proper
operation.
The jet pump can also be mounted on standard horizontal tanks. A
mounting kit with an AVC is furnished with tank. (Figure 6).

The installation, operation, and care of your Hydroglass* Pump is
very similar to cast iron pumps. We ask, however, that you keep
the following points in mind.
NOTICE: Use Teflon tape supplied with the pump for making all
threaded connections to the pump.
DO NOT USE PIPE JOINT COMPOUND.
1. Wrap 1-1/2 to 2 turns of Teflon tape to all male pipe threads
being attached to the pump. This will insure leakproof connec-
tions. Do not overtighten threaded fittings in the plastic pump.
If leaks do occur, remove the fitting, replace the Teflon tape,
and rewrap with 1-1/2 to 2 turns of Teflon tape and remake the
connection.
2. independently support all piping connected to the Hydrogfass _
Pump,

OPERATION
Priming the Pump
IA j NEVER run pump dry. Running pump without
CAUTION
water may overheat unit, damaging seals and possibly burning per-
sons handling pump.
L_'WARNIN_G_]NEVERrun pump against closed discharge. To
do so can bod water inside pump, causing hazardous pressure in
unit and possibly scalding persons handling pump.
1. Remove priming plug. Fill pump with water. Replace priming
plug. If a priming tee and plug have been installed for a long hor-
izontal run, be sure this line is filled and the plug replaced.
(Figure 2, Page 4).
2. Start the pump. Water will be pumped in a few minutes; the
time depending upon the depth to water and length of hori÷
zontal run. If pump does not prime, check for a possible leak in
the suction line. Reprime. Check to be sure suction lift - dis-
tance from pumping water level to pump - does not exceed 20
feet. See °Piping in the Well" on Page 4.
