For Proper Installation follow the listed instructions.

• Use 37 o JIC flare fittings.

• Use a non-hardening thread sealing compound.

• Prefill (prime) the pump on long runs to reduce dry running time.

• Check all unused pump fittings for tightness.

• Bleed system. Open bleed port approximately one turn.

Bleed for 15 seconds after clear oil begins flowing out of port.

Close bleeder valve tightly

• See page IV-1 if pump fails to prime or deliver

It is suggested that you DO NOT do the following:

• Install by-pass plug. (Will damage seal.)

• Use compression fittings. (Will eventually leak.)

• Use Teflon tape. (Will void warranty.)

• Use check valves. (Especially on gravity feed systems.) See Thermal Expansion, page III- 12.

• Exceed 10 psi (manufacturer) or 3 psi (NFPA) inlet line pressure.

• Exceed 6" hg. running vacuum (for Suntec “A” and “B” fuel units) or 2" hg. running vacuum (for Suntec “J” and “H” fuel units).
