Lochinvar SSB-i & s--01 Thermostat, Chattering Contactors or Noisy Relay Cause a, Removal

Page 5

CAUSE B

Control thermostat may be set too high or be defective.

SOLUTION - Reset thermostat(s). If condition is not corrected, replace thermostat(s).

CHATTERING CONTACTOR(S) OR NOISY RELAY.

CAUSE A

Contactors chatter or hum excessively when pulled in.

SOLUTION - Accumulation of dirt will prevent proper seating of armature. Remove contactor and clean. If proper seating is prevented by warpage of the frame or distorted coil, contactor should be replaced. Check for loose connections or wire connections with insulation under crimp.

CAUSE B

Contactors chatter only at pull-in or drop-out, or low water cutoff relay is noisy.

SOLUTION - Check for low voltage at control circuit and at secondary side of transformer. If voltage is below 120 volts, replace transformer. Low water cutoff probe may be fouled. To check, remove wire from LWCO probe and ground to tank. If LWCO board relay pulls in and stops chattering, the probe is fouled. To clean, drain water from tank, remove probe and clean probe tip.

THERMOSTAT

ADJUSTMENT AND RECALIBRATION

The thermostats are factory calibrated to produce 185-190ºF

(85-88ºC) temperatures. If recalibration is necessary, turn screw (G) counterclockwise to lower the set point or turn the adjustment nut (F) counterclockwise to raise the set point (must hold screw (G) at high stop). NOTE: one-sixth of a turn equals 12ºF (6.7ºC).

These thermostats are checked and accurately set at out factory. If recalibration is necessary, a 1/4 turn clockwise to screw (F) will decrease the temperature 12ºF (6.7ºC).

REMOVAL

1.Shut off power and drain tank; remove leads from terminals (E).

2.Loosen nut (A), then remove bushing (B) from tank. Thermostat with bracket and sensor bulb (C) can now be removed from tank.

INSTALLATION

1.Pull end of sensor bulb (C) into recess in bushing (B).

2.Insert bushing (B) and sensor bulb into tank; holding sensor bulb in place with capillary tube, tighten bushing (B).

3.Lock sensor bulb and capillary tube in place by tightening nut (A).

CAUTION !!

Do not overtighten nut, or sleeve inside of bushing will cut through tubing.

4.Replace thermostat on bracket. Replace leads on thermostat terminals.

CAUTION !!

Be sure tank is filled with water before turning on power.
