3. WATER CHEMISTRY
(Corrosive water voids all warranties)
For your health and the protection of your pool equipment,
it is essential that your water be chemically balanced. The
following levels must be used as a guide for balanced
water.
• Occasional chemical shock dosing of the pool or spa
water should not damage the heater providing the
water is balanced. However, it is highly recommended
that the heat pump pool heater is isolated via shut off
valves before any aggressive chemical treatment.
• Automatic chemical dosing devices and salt
chlorinators are usually more efficient in heated
water. Unless controlled, they can lead to excessive
chlorine level which can damage your heater.
• Further advice should be obtained from your pool
or spa builder, accredited pool shop, or chemical
supplier for the correct levels for your water.
4. INSTALLATION
CONSIDERATIONS
A WARNING: Do not install the unit within 3 ft (0.9m) of
fossil-fuel-burning heaters. Air intake along the sides of
this heat pump pool heater could disturb the combustion
process of the unit, and could cause damage or personal
injury.
● Mount the unit on a level, sturdy base, preferably a
concrete slab. The size of the base should be at least 3 ft
by 3 ft (0.9m x 0.9m) - slightly larger if hurricane tie-down
brackets are installed. See Figure 4 through Figure 6 for
more details.
CAUTION: The unit’s supporting base must be high
enough to keep it completely free of standing water at
all times.
Situate the heater carefully to minimize installation costs
while providing maximum efficiency of operation, and to
allow adequate service access, as follows:
• For unrestricted air intake and service access,
position each side of the unit at least 1 ft (30 cm)
from walls, pipes and other obstructions.
A WARNING: This unit is designed for outdoor
installation. It is NOT certified for indoor installation.
DO NOT install it in an enclosed area such as a shed or
garage, or under a porch or deck.
• This unit features an ‘up-flow’ discharge for quiet
operation. Air is pulled up through the evaporator coil
and discharged through the top grille. Allow at least 5
ft (1.5 m) clearance above the unit for unrestricted air
discharge. Do NOT install the unit under a porch or
deck. Refer to Figure 2 . Allowing cold discharge air
to recirculate back into the evaporator coil will greatly
reduce the unit’s heating capacity and efficiency.
To minimize water piping, locate the unit as close as
possible to the existing pool pump and filter.
• Irrigation water should be directed away from the
heat pump pool heater - irrigation water spray can
damage the heater.
• Rain water run offs - the unit is designed to operate
outdoors and can be exposed to rain. However, rain
water run off falling directly onto the unit can cause
damage and/or shorten the life of your unit. Such
damage is NOT covered under warranty. Install rain
gutters or rain diverters on your roof if the unit is
installed in a position where contact with rain runoff
may occur.
• It is important to keep the area next to the heater
clear of shrubs, bushes and chemicals containers.
They could prevent air from circulating fully through
the heater, and will affect the operation of the heater
or damage the heater.
