B. ASSEMBLY – VERTICAL POWER UNIT
1. Apply a liberal amount of grease to the motor and pump coupling joint.
2. Align the pump, coupling, and motor and place the pump on the motor.
3. Install the gasket on the reservoir lid and screw the pump and motor assembly onto
the lid. Torque the screws to 14 ft-lbs. Inlet of the pump must be toward the
Deltatrol hole and the foot of the motor must be toward the filler cap. Reconnect the
control box and wiring to the motor.
4. Replace the hose and suction pipe, with filter, on the pump. The suction pipe filter
should point toward the filler cap. Apply the recommended pipe sealant to insure a
pressure-tight fit.
5. Replace the Deltatrol onto the reservoir lid with the single screw placing the gasket
between the Deltatrol and lid. Note the Deltatrol port and gasket orientation for
correct assembly.
WARNING!
Under no circumstances should the speed control orifice be removed from
the Deltatrol to obtain faster lowering speed; a loaded lift can reach
dangerous and destructive speed and/or unnecessary closing of the
velocity fuses.
6. Replace the hoses and down restrictor pipe in the Deltatrol using the recommended
pipe sealant to insure a pressure-tight fit. A bolt and nut may be used in the open
hole of the Deltatrol to restrain to to the lid while the plumbing is being attached.
Remove the nut and bolt after the plumbing is complete.
7. Replace the gasket and set the lid on the reservoir, taking note of the orientation.
Replace the screws attaching the lid to the reservoir. One screw is through the
Deltatrol.
8. Replace the down solenoid and cover onto the Deltatrol using two screws and
reconnect the wiring to the solenoid.
9. Reconnect the electrical supply to the power unit and check for proper rotation of the
motor (see “Power Unit” in the Installation section). Test for hydraulic leaks.
Tighten the joints as necessary.
