Includes an in-line fluid filter, circulating manifold, and 3 ft. (0.9 m) whip hose. Installing Dual Heater Mounting Kit 222311 WARNING Before installing the heaters, dual heater mounting kit and circulating kit, follow the Pressure Relief Procedure on page 14. Disconnect all hoses from the pump. NOTE: Reference numbers marked with an asterisk (for example, 26*) are included in kit 222311. Apply pipe sealant (36*) to all male threads except at swivel connections. 1. Be sure the wall is strong enough to support the weight of the heaters, hoses, fluid, and stress caused during operation. Locate the holes for the heater wall brackets (26*) exactly as indicated on page 20. Note that one heater will be mounted above and slightly to the left of the other. Use the heater wall brackets as templates to mark the wall. 2. Attach a heater wall bracket to each heater’s mounting posts with the M8 x 1.25 screws and lockwashers supplied with the heater (44). 3. Use M8 or 5/16 in. bolts of the appropriate length and lockwashers (not supplied) to fasten the heater brackets to the wall. 4. Remove the fluid filter (4) and attaching hardware (3, 9) from the pump fluid outlet. Keep the filter, but discard the attaching hardware. See Fig. 5. 10 307932 Installation 5. Screw the 3/4 npt street elbow (28*) into the pump’s fluid outlet. Assemble the nipple (27*), check valve (29*), coupling (30*), and swivel (50*) as shown in Fig. 6. The arrow on the check valve must point down, toward the coupling. 6. Screw an elbow (32*) onto the lower heater’s inlet. Screw the coupler (63) onto the elbow. Attach the heater hose (31*) to the coupler. Connect the other end of the hose to the swivel (50*) coming from the pump outlet. 7. Screw an elbow (32*) onto the upper heater’s inlet. Screw the coupler (63) onto the elbow. Attach the second heater hose (31*) to the coupler. Run this hose to the left of and behind the lower heater. See Fig. 4. 8. Install the bushing (62) and a 3/8 npt nipple (33*) in the lower heater’s outlet. Screw the rigid end of the union (34*) onto this nipple, and screw the swivel end of the union onto the free end of the second heater hose (31*). 9. Screw the bushing (62) and a 3/8 npt nipple (33*) into the upper heater’s outlet. Screw the fluid filter (4) inlet onto this nipple. Unscrew the adapter (10) from the filter outlet. Screw the 1/4 x 3/8 npt nipple (35*) into the filter outlet, and screw the union (34*) onto the nipple. See Fig. 6. WARNING COMPONENT RUPTURE HAZARD To reduce the risk of overpressurizing your system, which could cause component rupture and serious injury, never exceed 90 psi (6 bar, 600 kPa) incoming air pressure to the pump. 10. Install the warning label (51) as shown in Fig. 6. 10 4 25 2 1 3 9 11 2412 4417B Fig. 5 307932 11 Installation Installing Circulating Kit 222312 WARNING Before installing the heaters, dual heater mounting kit and circulating kit, follow the Pressure Relief Procedure on page 14.

Apply pipe sealant (36) to all male threads except at swivel connections. 1. Remove the suction tube (25), fittings (52 and 53), hose (24), and adapter (12). See Fig. 5. Keep these parts for use later. 2. Screw nipple (54) and then the tee (48) into the elbow (11) at the pump fluid inlet. Screw the 1 x 3/4 npt bushing (55) and then the 3/4 npt x 1/4 npt bushing (49) into the branch of the tee. See Fig. 6. 3. Reconnect the bushing (12), hose (24), fittings (52 and 53), and suction tube (25). 4. Install the CIRC end of the three-way ball valve (40) in the bushing (49). Screw a bushing (39) onto the IN branch of the three-way valve. Connect the rigid end of the 45 union (38) to this bushing. Screw the swivel end of the union (38) onto the braided hose (37). Connect this hose to the main fluid return line. See Fig. 6. 5. Screw another bushing (39) onto the DRAIN end of the three-way valve (40). Connect the nylon fluid hose (41) to this bushing, and connect the return tube (42) to the other end of the hose. Place the return tube in the fluid supply container.
