INSTALLATION
Pump Sizing Information
The 1700 GPH performance was obtained through a 1" I.D. tube, with friction losses neglected. Using a
50' long ¾" garden hose reduces this performance to approximately 500 gallons per hour due to fric-
tion losses in the garden hose. If your area frequently has heavy rainfalls, (1"– 2" per hour), it may be
necessary to use 1" tubing. One inch ID hose should be available in most pool supply stores.
The number of gallons of water that your pool will collect in a rainfall of one inch per hour can be com-
puted as follows: Cover overall length (ft.) x cover overall width (ft.) x 0.6234 = Gallons per Hour.
NOTE: This is cover dimension, and not pool dimension.
Examples:
A 16' x 32' pool cover would collect 319 gallons (16 x 32 x 0.6234 = 319) in 1 hour, in 1" per hour rain.
A 20' x 40' pool cover would collect 499 gallons (20 x 40 x 0.6234 = 499) in 1 hour, in 1" per hour rain.
Physical Installation
The electrical outlet to be used must meet the requirements of the National Electrical code, as well as
local electrical codes, including grounding, and GFCI protection. Also verify that outlet is properly sized
and located for this pump. Your installation may require a certified electrician, or plumber. See Electri-
cal Connection section below.
If necessary, check your local plumbing codes to verify that
final installation will be in compliance with their require-
ments.
1. If using a garden hose to discharge the water, install the
garden hose adapter to the pump.
2. Connect a garden hose to the hose adapter, or use a 1"
nipple and flexible PVC tubing secured to the pump dis-
charge.
NOTE: The free end of the discharge hose must be
secured so that it cannot blow back onto the pool
cover in high wind or due to discharge water pressure.
3. Use the handle to gently lower pump onto the pool cover. Hold onto the discharge/garden hose if
necessary. While positioning the pump, be certain that you do not pull power cord plug onto pool
cover. The pump is equipped with an eyelet (opposite the discharge) for attaching a positioning
rope (not included). Use rope and garden hose to position pump on the pool cover.
4. It is recommended that two people position the pump. One person should hold onto the electrical
cord plug to prevent it from being pulled onto the pool cover while the second person positions
pump at desired location on pool cover. Once in position, the pump is ready for connection to elec-
trical supply.
